Found a bitcoin wallet from a backup I did on my Mac from six years ago and I have no idea what it might contain. Is there any way of examining the contents of the wallet without downloading an app the connects to resources online?

BitBox02 & KeepKey honest reviews

BitBox02 & KeepKey honest reviews

Hey, Bitcoin community 👋

I've just joined after a small research over the web, and decided to share some of my thoughts about these hardware wallets as individual experience.
KeepKey
The first hardware wallet I've received was the KeepKey, which acquired by the ShapeShift platform. It has some great advantages I liked at first sight:
  1. Using ShapeShift platform web to communicate between the wallet and the outside world. On the platform you could watch your assets with nice graphs, send & receive Bitcoin (and other ERC20 tokens) and trade between assets without commission (as long as you have FOX tokens - more on the ShapeShift subreddit).
  2. The most cheap hardware wallet, can be purchased for only 10$ here
  3. Great customer support! any question I sent them was answered quickly
The KeepKey via the web platform needs to be verified by a PIN (4 to 9 digits) of your choose. I didn't like it has there is no zero ("0") digit, only one to nine.
KeepKey verifies PIN screen
The PIN pattern on the KeepKey large screen (which is great advantage!) changes every time you unlock it, and numbers are not shown over the web (only dots). All actions on the web must be approved by one single button on the device it self and all the details shown very nicely!
Receiving Bitcoin on KeepKey - address and QR shown (and can be scanned)
KeepKey implemented a great privacy feature that each successful transaction changes the wallet's address. On the other, once you got the transaction done you can't see this address anywhere again.
Some of the disadvantages that made me move to the BitBox02, are:
  1. The lack of USB-C adoption. It was a bit frustrating looking for an adapter every time I wanted to connect it to my MacBook, which has USB-C ports only.
  2. Mobility isn't available, as you must use the ShapeShift platform (no native desktop program nor mobile application is available)
  3. Chrome is the only supported browser and the platform can't be used by any other.
  4. Not sure about the build quality. When I first opened the box, the upper half of the device wasn't parallel to the bottom, made me a bit nervous
  5. Not supported bech32!
  6. Lead to KYC
MicroUSB connector and edgy built
Overall, I find the KeepKey a great wallet, decently for this low price and the platform as some nice features. KeepKey has a Chrome extension which will be removed by June of this year, as the Google removes Chrome App Store.
------------------------------------------------------------------------------------------------------------------------------------------------
BitBox02 Multi edition
So, after the downsides of the KeepKey I was waiting for my wallet of choice, the BitBox02 which was built by the Shift Cryptosecurity, it is much smaller device but I find it more useful and much easier to use everyday.
The BitBox02 has two types, one for Bitcoin only and one for Bitcoin and some others. Currently not many coins supported, which isn't a great (Bitcoin, Ethereum, Litecoin and some other ERC20).
Shift Cryptosecurity has some other type of threat model, it has no seal tape on the box to verify it's a legit unboxed wallet, as many manufacturers (including KeepKey) does; they actually vacuuming the box and make it almost impossible to cut it without notice. As for now, they working on new awesome feature called "Tep", a really innovative idea! watch the video, it's really great!
Inside the box there was a USB-C to USB-A adapter (awesome thing to provide!), extended USB-C cable, stickers, microSD card (soon to be explained why, but again, awesome they send it included) and the device it self.
Some of the advantages are:
  1. Native desktop program for MacOS, Windows and Linux
  2. Android application (hope for iOS soon as well), which is great for mobility
  3. Easy to use and guided through every step of the initialisation
  4. MicroSD card used to backup (not encrypted) the keys, another method for users, along with the 24 mnemonic passphrase. It's nice feature to have for those who aren't that technologically.
  5. Secure chip built-in the device
  6. Able to use with Electrum
BitBox02 has no buttons, it has a unique gesture touch sensors on it's sides and it used a slide, tap and hold gestures.
Supported low and capital letters along with all 0-9 digits
The device will wipe it self after 10 times of wrong password. Backup of the keys can be done by the microSD card or by the 24 words.
BitBoxApp, receiving address must be verified on the device
Verify on the device by single tap
Same as the KeepKey, the BitBox02 generates a new address each time you made a successful transaction, keeping the privacy in mind and focused. another nice feature to have is that the BitBox02 has U2F ability, which means websites like Google, Facebook, Twitter and else can be 2FA with a physical security key, a great way to secure accounts.
------------------------------------------------------------------------------------------------------------------------------------------------
In my opinion, KeepKey is a great wallet but I liked the BitBox02 more, specially because of the mobility and the ease of use on any OS no need to download Chrome, although it's bit more expensive.

Reddcoin (#RDD) May 2020 Team Update, or “New Wallets & What to Expect when You’re Expecting PoSV v2”

Link to Medium post -> https://medium.com/@techadept/reddcoin-rdd-may-2020-team-update-or-what-to-expect-when-youre-expecting-posv-v2-b708319221ce?sk=b5eafc57b67327d99a35380f390d77ca
Hey, ReddHeads!
To new ReddHeads, welcome! To old ReddHeads, welcome back! It’s an exciting time in Reddcoin (RDD) for a lot of reasons, and we, the Reddcoin Core development team, wanted to get a brief update out to touch base on some of the highlights.
Attached are some screenshots of our work to enhance security and interoperability, and to extend support to MacOS Catalina in our newest v3.10.1 wallet.
This wallet release also includes components and performance & security upgrades taken from the Bitcoin 0.10 codebase, and we will be following much of that same development and enhancement in our Reddcoin Core wallet in the future, with 0.11 up next.
This release is not a required upgrade (except for Catalina users), but will benefit user experience and security significantly. We’ll be publishing, of course, a full public changelog, hashes and commit list in Github along with open source code and compiled executables upon release.
But the major changes in Reddcoin v3 are just about to start, as PoSV v2 gets ready to activate. Released to the community on 12/24/19, the blockchain has (at time of writing) reached 8197 of the required 9000 block threshold, or 91.08% of our goal of supermajority. If you haven’t upgraded yet, or aren’t staking, it’s time.
After PoSV v2 activation, older (v2.x, v1.x) wallets will not be able to send transactions or stake.
We anticipate activation to be reached within a very short time period, especially once our Mac ReddHeads are able to participate, and as such we want to ensure that information for the general community is available and up to date.
1) AM I GOING TO LOSE MY REDDCOIN (RDD)??
a. NO. This is a soft-fork, and whether you’ve upgraded to a v3 wallet or not, you cannot lose your coins. The blockchain itself will remain the same, it is only the rules of staking that are changing. Older wallets WILL stop functioning immediately after the threshold is passed and PoSV v2 activates, but all that is required at that point to restore functionality is to install the new v3 wallet. If you need help, please join our Telegram or Discord live chats for community or Dev help directly. No ReddHead left behind!
2) WHAT DO I NEED TO DO??
a. If you’re staking, make sure you’re using a v3 wallet, preferably the latest version. Right now, that is v3.0.1, in a few days with the above noted release it will be v3.10.1. You may also wish to use the “Backup…” function at this time to make sure you have a backup of the only important file you need, the “wallet.dat” file. There are no mobile staking options at this time due to the nature of our PoSV protocol, but you can deposit coins in the dev team-run ReddBot on Telegram to stake if you have no other options until a mobile staking option is made available.
b. If you’re not staking, or are holding on Coinomi, or Guarda, or other 3rd party wallets, or on an exchange, or a paper wallet, you will also have no operational issues, but of course you’re encouraged to help secure the network and validate transactions, by starting to stake.
3) I’M BORED. ENTERTAIN ME!
a. OK. As successful as our first meetup was, we agree. Look for an upcoming benefit concert from Reddcoin and hopscotchmafiamusic.com at the end of this month. No, really. Free awesome music, cool people, come have a bit of fun with the ReddHead community virtually!
4) I’M HUNGRY. FEED ME!
a. Well…with the activation of PoSV v2, and the creation of Reddcoin’s self- funded development mechanism, we’re very excited to be able to provide at least some resources and RDD toward the Reddcoin Community Food & Supply Bank initiative in the near future. Reddcoin Core will also be donating any funds received in connection with the above concert event to worthy and working charities, especially if we can convince them to receive RDD (or BTC). Watch for further info about this and other charity initiatives to come. Our own efforts rely on PoSV v2 activation, but will be documented publicly and transparently as they evolve.
5) I WAS USING RDD AND THEN X (or Y or Z) HAPPENED AND NOW I’M BROKE AND SAD AND ANGRY. HELP ME!
a. Perhaps you’ve not heard about Reddcoin’s uniquely conceived “Reddcoin Restitution Fund”. Been hacked? Lost a few coins when your computer crashed or your brother formatted your hard drive? Reddcoin has committed a percentage of PoSV v2 funding to give back to users legitimately affected by events beyond their control.
Cases of extreme stupidity will be vetted on a case by case basis, obviously fraudulent claims will be laughed at, and all cases will be dependent on a reasonable standard of proof and verification. This is also going to be an evolving and good faith approach to giving back to our real ReddHead community, and will require both transparency and abuse-prevention to be successful, but we look forward to being able to help those who deserve and need it. NOTE: Trading and speculative losses aren’t covered in any of this. Obviously.
6) I WANT TO KNOW MORE!
We’re working right now to rebuild our main website www.reddcoin.com into a more informative and resource-rich site, but it’s a good starting point. We are in the process of updating our roadmap to cover the end of 2020 and the future as well, and both of those should be available and will be announced within the next month.

Move Paper Wallet To Secure Long-Term Solution

Hi, I got into Bitcoin mining a long time ago, eventually sold half my coins and kept half on a paper wallet made from a popular online wallet service. For a few reasons I want to move this to a modern and secure way to store the coins.
My idea is to make a VM on my Macbook in VMware of macOS and keep it virtually "air gapped" by uninstalling the virtual network card and disallowing copy & paste as well as shared folders. On this VM install the Electrum software as the main wallet and generate a new public and private key pair. Export the wallet in encrypted form and store on a NAS as well as AWS S3. Print the mnemonic (12 word backup phrase? I assume Electrum can help with this?) and store in a safe at home. Buy a Ledger Nano X or Nano S and hook up to this air-gapped wallet, so this would basically be a second backup, and could be used to spend the coins without the use of the air-gapped VM.
Then install the Electrum software on my actual Macbook's user-space, import the public key and the private key from the legacy Bitcoin address on the paper wallet (yeah, long-time old paper wallet...) and send all the coins to the air-gapped wallet address, set up as a watch-only address on this Electrum client. Basically use this to empty all the coins from the old legacy address to the new address generated on the air-gapped computer.
Does this sound safe/sane? Am I missing something/is there a better or easier way? Any experience with the Ledger Nano X/S and is it actually trustworthy?
I really appreciate feedback on this. It has been a _looooong_ time and the BTC world has changed a _lot_.

Recovered my 4 year old wallet

I am super stoked about this. A long time ago (2011-2015), on an old machine (an iMac), I used Armory. I was selling that old machine, so I swept my keys into an electrum wallet, and I replaced the hard drive that was in it knowing one day I would come back to it.
Well, a couple years after that, I had issues because I couldn't access the files from that hard drive without another mac (trust me, I tried. I password protected that hard drive so only booting it from a legit mac would grant me access to it). And, I lost my paper backup... Luckily, my friend had an old mac mini he let me borrow, and I sat on it for about another 2 years.
Today, I finally pulled my wallet off, and could not remember the password I put on the wallet. Thank god for the btcrecover tool, because that cracked my password in under a second (I remembered what it could of been, but not exactly. I would have not guessed what it actually was).
It's not a huge amount of bitcoin. But it was more than I remembered keeping (more than 1). Still face-palming though at some of my transactions. I had my armory wallet going back to 2012. Sooooo many bitcoins went through that wallet, mining on slush with my petty mac GPU. I had one of the first OG ASIC butterfly 60GH/s miners too. If only I had kept more, I could quit my day job now. Oh well.
But, I thought I'd share an antitheses to the old "I lost my old wallet. please help!!!" posts. Probably going to continue sitting on it for a few more years. And now that I've regained interest, I'm going to start running a full node again. To the moon!

Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

How to Upgrade?

Windows
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer.
OSX
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), run the dmg and drag Groestlcoin Core to Applications.

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet

Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network.
GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – GroestlcoinSeed Savior

Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases.
This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats.
To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.

ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

Verify Electrum Wallet GPG and Download Signature on MacOS Mojave?

A couple years ago, back when Bitcoin and Bitcoin Cash split, I moved my paltry amount of bitcoins into an electrum wallet on my windows machine. That machine has since had a complete death due to overheating, but I had multiple backups of the wallet generating pass phrase so in theory I should be able to access my wallet through Electrum on a different machine. I now have another machine running Mojave, and I want to verify the GPG signature before installing Electrum from the downloadable binary.
Unfortunately, I don't know how to do this and copy-pasting the commands listed in the documentation doesn't do anything because bash can't find the gpg command: https://electrum.readthedocs.io/en/latest/gpg-check.html
I'm at a loss as to how to proceed. I found a tutorial here: https://bitzuma.com/posts/how-to-verify-an-electrum-download-on-mac/ that is a little involved, but it is from 2017 and I'm not sure if it's still up to date.
Edit: For posterity, I used these two sets of instructions to get things properly set up and verified: https://bitzuma.com/posts/how-to-verify-an-electrum-download-on-mac/ , and https://electrum.readthedocs.io/en/latest/gpg-check.html

I just lost my $170K wallet secure your wallets

It’s not a joke. You don’t realize shit happens until it happens don’t be that guy in my position. Please copy your backup codes and secure your wallet it’s not a good feeling
It’s not even about losing 170K it’s about losing a wallet with that much money in BTC. It’s there but you cannot use it. When I start seeing the price go up is when it’s going to piss me off
40% reward to person that finds a way or gives me an idea to restoring the wallet. Read bottom of post.
Story:
I had purchased a new 27 inch iMac for our new office. I later got so much negative feedback about how it was just too big for my desk and that a MacBook would be better.
Anyway after completing my new office I decided to go on holiday for a week which was fun but had this bad feeling I don’t know why.
I got back to my office and decided I would take a trip to London as there was a super car conference (I’m into cars). I then decided to go clothes shopping as clothes are a lot cheaper in my home country. I decided going to the fancy mall near by. I then bumped into the Apple store I bought my iMac from and asked an employee if I could swap it they said no. I’d have to return it first. I thought it would be late now because it had been a while. We looked it up and it was the 14th day of purchase, the employee told me I had 4 hours to return it so I quickly ran home and brought the iMac back.
My wallet was newly transferred onto a Blockchain wallet created on the iMac after I had an incident with an offline wallet and got scared. I used auto generate password by apple with no iCloud to backup the keychain. When creating it i took a screenshot on the iMac of the recovery phrase which is also now gone.
I realized at night and called Apple all over the world to try and find somebody that could help. I went to the store 2 hours before it opened Incase there was a delivery van taking the products back to China which is the procedure I was informed by the employee on the phone. The Apple store finally opened, the manager went to check and informed me it was formatted as it’s the standard return- refund procedure.
Fucked
Bitcoin recovery companies?
Those companies try brute forcing into your wallet offline. It’s only and mainly mostly possible if you remember your password and are sure it’s just a typo mistake. Example: your idea of the password: Password2019. Real password: Passsword2019
It would take an average of 100 years from my research to brute force into my own wallet. Correct me if I’m wrong
Questions: just making sure,
If a new device doesn’t have iCloud Keychain installed does the Mac OS still recommend a generated password?
Apples regular password generation function:
Aa8-by9-ANk-999
Is this really that hard to brute force offline?

Does browsers such as safari or chrome sync the passwords too? Or is it just keychain.

If anybody has any other ideas to possibly gain access please do contact me. You will be rewarded 40% on success

So I made a thing - AceTipper! for Bitcoin Cash. If you love tipping in BCH, this app will print your tip as paper wallet to be gifted, keeps track of them to see who actually claims them, and (best of all) you can reclaim the gift after a period of time if it goes unclaimed.

AceTipper is an application that will help you print out paper-wallets for the purposes of tipping Bitcoin Cash (BCH) to people who may or may not be familiar with Bitcoin.
This application looks to solve 2 problems that I saw.
1) The need for the recipient (who may not be familiar with Bitcoin) to have to install a wallet in order to get some BCH can be a barrier. So with this app, you print out the tip as a paper wallet so you can hand them out to anyone anywhere.
2) Another problem I saw was that many folks (like servers at restaurants) may take the Bitcoin Cash tip, out of politeness, but then never claim them. Therefore, you lose your funds for no benefit to anyone. So with AceTipper you can track who actually claims the tip - and if nobody claims it within a period of time of your choosing, you can simply take those funds back.
This app manages your tips, prints paper wallets of various designs (one design so far actually), but also allows you to take back your tip if it hasn't been claimed for a period of time - say a year.
If you have any feedback, I would love to hear about it.
This app is Windows and MacOS.
Download the Windows and MacOS Installer from Github
bitcointipping for questions / feedback.
Some notes:
This runs completely on your machine as a desktop application (ElectronJS).
The seeds for your wallet are stored on your machine.
You are absolutely encouraged to make backups of your wallet seed.
This is an open-source application.
Here is a sample of what a printed BCH tip looks like.

My Blockchain.info account got hacked and I lost $7k worth of Bitcoins.

I got my Blockchain.info account hacked yesterday and lost $7k worth of coins. I'm not sure how they got my identifier and my password contained 12 characters (including numbers and punctuation) but contained a word in it.
I'm not sure how it got hacked but I suspect they got into my Gmail or Dropbox where my backup wallet was stored. I've since enabled 2 Factor Authentication in Gmail and am using super strong passwords that probably could withstand any brute force attack.
I'm not a techie and so let this be a warning to anyone on Blockchain that you must super encrypt your password or store your coins offline. I'm pretty choked but if this post helps a few people not lose their coins, then some good will come of this.
My coins went to IP address 134.129.23.124 and sent to address 1HmVdtqSxEReh4GVqLbSsgH7YArQb8xGq4
I was pretty choked about it yesterday but feeling a bit better. I got a super great life, the best girlfriend in the world and a lot to be immensely grateful for despite this robbery.

Feedback on new Nano "cold" storage feature in Q Vault

Hey guys, hope you are well. I'm looking to get some feedback on an idea I just had. A team and I are currently building an open source password manager for Mac, Windows and Linux. (https://qvault.io)
The goal of the manager is to have all the security features and configurations such that cryptocurrency keys can be safely stored inside. For example, offline use, cloud backup integrations, virtual keyboard, etc.
Anyhow, I just finished importing a nano wallet backup into my personal Q Vault. (simply a valid address and the associated seed), and I was thinking I should be able to generate that address and seed from within the vault, in the form of a button that is "generate simple wallet". Not only would it be more convenient, but it would be way more secure (no need to copy/paste the keys into the vault). This would obviously be only for HODLers, because the vault has no capabilities to spend the coins. Once a user wants to move the funds, that seeds would need to be imported into a "hot" wallet like natrium.
Anyhow, I'm thinking of doing this for Bitcoin and Nano first, and maybe adding more coins down the road if the feature is used. What are your guys thoughts?
Go ahead and download the app and play with it if you want to get a feel for how it would work.

The History, The Current State And The Future Of NavCoin

The History, The Current State And The Future Of NavCoin

This is it. If you're interested to see what NAV is all about, this is the ultimate guide for you. You will learn about the history of NavCoin and how it evolved. You will learn about the current state and features of NavCoin and you will learn about the exciting new features that are planned and coming up in the (near) future.
So buckle up, this is going to be a long ride!

Table Of Content


Introduction - What is NavCoin?


The History

Introduction
The following chapter will summarize and break down the history of NavCoin in a few sentences. NAV started a long time ago, went through rebrandings and changes of the core team before it became what it is today.

SummerCoin
NavCoin was initially first introduced under the name SummerCoin on April 23 in 2014. SummerCoin was a fork of the Bitcoin blockchain. It used to have a PoW/PoS hybrid algorithm with a block time of 45 seconds.

SummerCoinV2 /NavajoCoin
Soon after the initial launch of SummerCoin, the original developer left and SoopY (soopy452000 on bitcointalk) took over as the main developer and rebranded the project to SummerCoinV2 respectively NavajoCoin and introduced new features.
The name NavajoCoin was chosen in honor of the Navajo Code Talker. The unbreakable Navajo code was used to encrypt highly classified military information and commands and decrypt the same in WW II.
SoopY introduced a technology which allowed sending transactions anonymously and private. This technology was called "Navajo Anonymous Technology". SoopY also released a new wallet and set the Proof of Stake rewards at 10% for the first year, 5% for the second year and 2% for every year after.

NavCoin
On August 12, 2014, Craig (current lead core developer, pakage on bitcointalk) started to get involved with NAV by helping to set up a website [10].
It was officially announced that Craig joined the core team as a "Wallet & Web Developer" on November 06, 2014.
The last tokenswap and restart of the blockchain of NAV happened on May 12, 2016.
Soon later, SoopY stopped showing up and Craig stepped into the role of the lead core developer. Since then, Craig has assembled a strong team with which he built NavCoin into what it is today.
Currently, Craig and the NavCoin Core team is located in New Zealand and they are actively developing many ground-braking features which differentiate NAV from other cryptocurrencies. You will read more about that later in this article.

The Current State

Introduction
The year 2018 has been a thriving year for the NavCoin ecosystem. Despite the USD price of NAV not reflecting it, in 2018 the core team has developed a whole bunch of new features. Also the core content creators published the first official guidelines that function as an orientation guide for community content creators. This chapter will give you an overview of the current team, the features, the prior mentioned guidelines and the community of NavCoin.

Core Team [1]
Last year, the core team has grown alot. It contains of developers, content creators and interns. The core team are employees of Encrypt S, the New Zealand's leading blockchain R&D lab. Encrypt S is developing blockchain solutions since 2014 and values building open-source software highly.

Craig MacGregor - Chief Executive Officer
Craig is the CEO of Encrypt S and the founder of NavCoin. He is one of the world's most experienced blockchain developers. Craig founded NavCoin in 2014 and is developing software for it since then. He has assembled a strong team of like-minded people. Craig also speaks at seminars and conferenced. Some of the companies and conferences he did blockchain education sessions at are Oracle, Xero, Air New Zealand, Blok Tex and trademe. Together with the team, he is also doing a education series on YouTube where he explains upcoming features in-depth for the community.

Alex Vazquez - Chief Technical Officer
Alex is the CTO of Encrypt S and the most active contributor to the NavCoin core Github. He has incredible knowledge of blockchains and proposes and implements solutions for challenges and features. He supports community developers frequently and answers any questions of the community thoroughly. Like Craig, Alex is developing software for the NavCoin ecosystem for a very long time. Alex speaks at universities at times and educates students about the blockchain technology.

Paul Sanderson - Lead Software Engineer
Paul is the Lead Software Engineer at Encrypt S. He has a flair for technology. His technical and management skills are perfectly suited for consultancy and investment advising. He also frequently contributes to the NavCoin core source code.

Rowan Savage - Senior Software Engineer
Rowan is a full stack software engineer with more than a decade experience in developing complex front-end web applications. He joined Encrypt S in February 2018 and has since been involved in the Valence Plattform, the Kauri Wallet and NavCoin Core. You will read more about these feature/projects later.

Carter Xiao - Lead UX/UI Designer
Carter specializes in user-centric design and is also very talented with 3D animation, motion graphics and programming. One of NavCoins core principle is "Simplifying Crypto" and UX/UI is a very important part of that.

Matt Paul - Software Engineer
Like Rowan, Matt is a full stack Software Engineer. He joined the core team in Mai 2017 and has since worked on NavPay, NavPi, the Kauri Wallet and NavCoin Core. Kieren Hyland - Chief Strategy Officer Kieren is one of the employees that are working for Encrypt S for a very long time. He is the CSO and is a digital strategist and growth hacker with a passion for new technology and has a lot of experience in online marketing. Laura Harris - Creative Director Laura has a combination of commercial and creative flair. She manages the social media accounts for NavCoin and ensures, that NavCoins' message is always powerful, relevant and distinctive. John Darby - Content Creator John is an internationally awarded Technology and Financial sector marketing communications specialist. He is one of the Core Content Creators for NavCoin.

Features of NavCoin [2]
The following features are currently available and have been developed in the last months and years. It is sorted from newest to oldest.

Static Block Reward
The soft-fork for the enabling of static block rewards have been accepted and became active recently at 5th January 2019. This means, that the block reward was changed from a percentage based reward to a static reward. This will incentivize the stakers to have their node online 24/7 which increased the security of the network. It also aligns NavCoin with the PoSv3 specification. With this implementation, the yearly inflation will be 3.6% currently and will exponentionally decrease because of the static value of the rewards. Every staked block will now give the staker 2 NAV. Depending on how many people are staking, the yearly percentage varies. With the network weight currently being around 20'000'000 NAV, stakers earn around 10% rewards from staking 24/7.

Cold staking
To provide extra security to participants in the staking process in the NavCoin network, the core team decided to implement cold staking. This allows to store NAV offline and still be able to sign staking inputs. Looking forward, a possible integration into the Ledger Nano S would mean, that one can stake NAV securely from a offline hardware wallet. How cool is that?

OpenAlias
One of the core principle of NAV is to simplify cryptocurrencies. Many non-technical people are deterred from the long, cryptic addresses used in wallets. When sending funds, you have to make sure that every single letter and digit is correct which is nerve-wracking for the average person. NavCoin has implemented OpenAlias, which allows to transform the wallet address into a email-like form. Everyone can register a name like "[[email protected]](mailto:[email protected])". Funds can then be sent to this name, which makes sending crypto much easier and less error-prone.

Community Fund
This is the one big feature I was most excited about. NavCoin core has implemented the first fully decentralized community fund. Acceptance of proposals and release of funds is all approved by the decentralized network. No central authority has access to the fund. The community fund enables everyone to propose their ideas to the NavCoin community and to get paid to implement these ideas. Everyone can propose whatever they like (of course there is a higher rate of success if the proposal contributes to the NavCoin ecosystem ;-)). In fact, this article was sponsored by the NAV-Community by voting "yes" for my proposal. The fund works like this:
For a fee of 50 NAV, everyone can create and present his idea/proposal to the entire NavCoin network. The fee is here to help prevent spam attacks. Proposals can literally be anything - be it development, marketing or anything else you can some up with.
After creating the proposal, everyone contributing to the NavCoin network can then decide if they like the proposal of not. They vote with "Yes" or "No" for the acceptance of the proposal. Voting happens via staking. Every transaction that gets validated by you gives you one vote. This means that the more NAV you are staking, the higher your voting weight is.
The proposal stays in the state "Pending" until it is accepted or rejected. To be accepted, a proposal has to have a participation of at least 50% of all staked blocks and at least 75% of these votes have to be "Yes"-votes. Like-wise to be rejected a proposal need 50% participation of the network and 75% of these votes have to be "No"-votes. Additionally, if a proposal didn't pass after 6 voting cycles (about 6 weeks) it is also rejected.
After a proposal has been accepted, the creator of the proposal can start his work. When the work is finished, or at in the proposal defined checkpoints, the proposal creator can create a payment request for the full or part of the requested funds.
The NavCoin network can then again decide, if the work is what the creator promised to do and vote for the funds or reject the payment request because it was not what he promised. This mechanism ensures, that the funds are only release if the creator of the proposal did what he promised. The NavCoin network decides everything, there is no central authority which makes the community fund 100% decentralized.
The community fund is quite new but there have already been some proposals that were accepted like paying for the development & hosting of NAV block explorer, the creation and distribution of NAV car stickers to the community for free (or paid by the community fund), the funding of interns for NavCoin Core, translation of the website into other languages and YouTube videos. What ideas could you come up with? By the way: this article was also sponsored by the community fund :-)

Proof of Stake
Like said before, NavCoin uses the Proof of Stake algorithm to create and validate blocks. Participants of the NavCoin network can earn rewards by putting their coins to stake and thus validating blocks and securing the network. The reward used to be 4% fixed but recently changed with the implementation of PoSv3. Currently, rewards for stakers that are staking 24/7 is about 10% but it is dependent on how many people are staking. If more nodes come online, this reward will go down. If 90% of all NAVs would be at stake, stakers would still earn 4%.

Tutorials And Guidelines [3]
The NavCoin Core team pushes the community to contribute to the NavCoin ecosystem constantly. They emphasize that NavCoin is an open source project and everyone can contribute. The team tries to make it as easy as possible for the average person to contribute and thus created different tutorials and guidelines.

Tutorials To Contribute To The Website
The whole website is open source. Everyone can contribute to the website. The team created different guides for people to follow [4].

The NavCoin Developer Manifesto
The content creator core team has build a developer manifesto. It defines the values that should be uphold like for example that they will always operate in the best interest of the network. If defines the principles, purposes, scope of involvement and operational requirements [5].

The NavCoin Content Creation Manifesto
Similar to the developer manifesto, there is also a content creation manifesto. Again it defines the principles for creating content, the purpose, the scope of involvement and the operational requirements [6].

NavCoin Brand Guidelines
In addition to the content creation manifesto, there is also a brand guideline booklet. This should help content creators to create images, videos, articles etc. in the same style as the core team. It defines the NAV brand. The brand guidelines contain definitions, the language to use (words to use, words not to use), the tone of voice, what the community aspires to be and what we discourage to be. It also contains the logo pack which can be used in graphics etc. It describes correct logo spacing, logo placement, the colors of NAV and different web assets. It gives tips about gradients and overlays, the typefaces (with a font pack) and many more. Check it out yourself [7].

NavCoin Educational Series
The core team has decided to actively involve the community in the creation of new features. For this reason and to allow users to ask questions, they created the NavCoin Educational Series. The core team schedules an online live meetup which can be joined by everyone. On YouTube they do live-streams and explain upcoming features. Examples of these series are explanations for cold staking, static rewards (PoSv3) and the community fund. The community can ask questions live and the core team will answer them immediately.

Community
During the last year there have been an influx of software developers from the community starting to create features for NAV.

navexplorer.com
An examples is navexplorer.com which is programmed by community developer prodpeak and is a block explorer for NavCoin. Additionally, it functions as a interface to see what is going on in the community fund. It shows pending proposals and payment requests.

NEXT Wallet
The NEXT Wallet is an alternative wallet for NAV and other cryptocurrencies. It has a beautiful user interface and is additionally the easiest interface to interact with the community fund (create proposals, create payment requests and vote for proposals and payment requests). It is programmed by community developer sakdeniz who put hundreds of hours into it during last year.

There were also some marketing activities starting to emerge with the release of the community fund. Some of these were for example free stickers for everyone in the NAV community to stick to their car / shop / window etc. or YouTube videos of CryptoCandor and Cryptomoonie that explained the details of NAV. I am sure, that with the 500'000 NAV available in the community fund per year there will be an influx of gread ideas - development as well as marketing activities - that will be funded.

The Future

Introduction
These features are planned for the future. Many of the following features are part of the 2019 roadmap. Some will not be described in great detail because not much is known about them yet. I've still listed them as they are part of what is yet to come.

Features
Rimu - Improved Privacy Solution
NavCoin used to be a optional privacy coin. That means, that you could choose to send a transaction in private. NavCoin was criticized for the way it handles private payments because it relied on a few servers which didn't make it that decentralized. The technology was called "NavTech" and was a secondary blockchain that obscured the transaction and the amount that was sent. NavCoin Core is currently developing a new improved privacy solution that will make the private payment system completely trustless and districuted and runs at a protocol level. Alex of the NavCoin Core team has published a paper that describes this new privacy solution. It's called Zero Confidential Transactions and can be found here: https://www.researchgate.net/publication/330366788_ZeroCT_Improving_Zerocoin_with_Confidential_Transactions_and_more. What I want to highlight is the collaboration between Alex as the proposer of the solution and the Veil team, a Bitcoin Core developer and Moneros main cryptographer as reviewers. When the best work together, it will be interesting to see what the outcome is!

Valence Plattform [8]
Valence is an applied Blockchain platform that can help businesses realise the tangible benefits of blockchain. You can think of Valence as a platform with which you can build Anonymous Distributed Applications (aDapps) with. But Valence is a different kind of platform that enables developers to create new types of blockchain applications. The problem with current (turing complete) dApp platforms are their complexity and rigid nature. Security holes in smart contracts and scaling issues happen frequently [9].
Valence provides transitional pathways that let businesses migrate only part of their activities to the blockchain without having to restructure their entire business model [9].
Valence will provide a spectrum of blockchain application solutions which sit along the decentralized spectrum, offering businesses simple ways to dip their toes into the blockchain at minimal risk or complexity [9].
Thanks to the proof of stake nature of the Valence blockchain, more of a node's resources can be used for processing and routing application data which makes the platform faster and scalable.
Valence aims to make building blockchain applications as accessible to the general public as WordPress or Squarespace has made building websites.
The developers NavCoin and Valence aim to make Valence extremely easy to work with:
A Valence application could be an open source mobile or web application that submits unencrypted or encrypted data directly to the blockchain. The only configuration necessary for the app developer would be setting up the data structure. Once they've done that they can start writing to the blockchain immediately.
The Valence blockchain interface is language agnostic, meaning developers are free to build applications in whichever language they're familiar with, which greatly reduces the barrier to entry.
As the platform progresses, Valence will introduce more and more smart contract templates in collaboration with the development community. These will be like plugins that users can simply select and configure for their application, without having to reinvent the wheel and risk contract errors or spend countless hours of research to program them.

NavShopper
The following information is taken from the latest weekly news: NavShopper is a new project which will allow people to spend NavCoin on a growing list of retailers and service providers. NavShopper sits between traditional retailers accepting fiat and NavCoin users and purchases products on behalf of the user by managing the crypt-fiat conversion, payment and shipping. This project will unlock many more ways for people to spend NAV on existing websites/marketplaces without requiring each site to individually accept cryptocurrencies. Some of the prototypes we are working on include crediting your Uber account, buying products on Amazon and donating to charities.

Kauri Wallet
The Kauri Wallet aims to be an open-source, multi-currency wallet which functions as a foundation for other features.

Kauri Enhanced
Enhancements to the Kauri Wallet will allow multiple accounts, pin numbers, recurring payments and more.

Kauri DAEx
The Kauri DAEx is a Decentralised Atomic Exchange that utilises the features of the Kauri Wallet and enables users to create safe peer to peer atomic exchanges for any currency supported by the Kauri Wallet. NavDelta NavDelta will be a payment gateway that allows users to spend NAV at any business which accepts currencies supported by the Kauri Wallet. NavMorph NavMorph is a fusion of Rimu and Kauri DAEx and will allow to privately send every cryptocurrency supported by the Kauri Wallet.

Outro

If you have made it this far: Congratulations! You have learned about how NAV evolved, what its current state is and what the future will bring. To sum all up: NavCoin has made incredible progress during last year and released many long awaited features despite the bear market. Many more exciting features are yet to come and it's going to be very interesting to see where we will stand on this day next year.

Giveaway

Unfortunately, the giveaway was not possible in the cryptocurrency-subreddit because of their rules, so I'm doing it here :-) As a surprise, in the next 2 hours I am going to send some NAV to everyone who wants to try out the awesome features and NavPay you read about above.
To get your NAVs, all you have to do is the following:
If you liked the experience, I'd be happy to hear back from you :)

I am so sorry BCH community, please accept my apology.

I'm sorry BCH community. I always thought this was just another scam. I've falling for all the brainwashing online and never believed in anything other than bitcoin.
It's been easy for me to believe what I wanted to believe and I'll explain why I wanted to believe in BTC. I first heard of bitcoin 6 years ago and I shrugged it off as being something that's pointless, each year after that there was another article that caught my eye about the huge rise in value, everytime I saw it (not lying - every year I saw it), I thought damnit! I should just have bought it, but I guess it's too late now.
A few years later I bought some Ethereum, it was VERY cheap so I bought it, even though I didn't understand it at all (it was very cheap, I bought hundreds with the hopes that it will do what BTC did), I completely forgot about it, and two years later a friend told me ETH was $400 - I rushed to open up my wallet and sync it and realised I don't remember the password, this would've been worth millions, in otherwords I would have had true freedom. I spent around 3 months researching ways to try and recover my password and eventually realised that there is no way, at this point my mac got extremely slow (I blame Sierra) and I had to format / reinstall it. I figured there's no point in taking a backup of the eth directory as I don't have the password to decrypt the wallet anyway, so I nuked it and said goodbye to my freedom.
Now, fast-forwarding, me and my girlfriend are switching phones (she wants and iPhone, I want an Android), the next step for me was to move all my data from the iPhone to the droid (Google Authenticator, mail accounts etc.) as I got to my Notes application I found a note containing my ethereum wallet password. I cannot explain to you how sick this made me feel, even just thinking back about it now is making me feel queesy.
I could have had true freedom, I could get myself, my girlfriend and our child out of South Africa to be in a better country, with lower crime rates, less risk of my rape - better education etc. I could have said goodbye to all of my stress and worries - the long 16 hour work days, it would all have been gone, but I screwed it up - twice.
This made be feel sick and I stayed away from crypto for longer, last year (2016), was the year I decided that I am sick and tired of worrying about our futures, sick of worrying about a robery or a hijacking, sick and tired of long working hours and almost 2hour long commutes on a dangerous freeway. This was the year that I would get into crypto. The first thing I realised is that my reasoning for entering crypto was to seek financial freedom, I didn't just want to buy and hold a currency, I wanted to help the community and make some money doing it, so I took a loan - and built a rig (cheap GTX 1060s) - so far it's helped a lot, the money I've been mining helped keep my nose above water. I haven't been able to pay off the loan yet, but atleast the monthly expenses are all covered.
I decided to keep money aside and save it (instead of buying new cards every n months) into a type of savings account, where I'll keep it until it's enough to build another rig, the second rig will help my pay off the loan, but there's no point in spending the cash on parts that are useless on their own. It worked out pretty well, but unfortunetly even after the doubling of BTC price, it's still not enough for a new rig - however I believe I can get there, the reason I wanted you guys to be wrong is that you were a contradiction to everything I was led to believe the last couple of months and this project (the reports of the "flippining" threatened my survivability).
This latest "dip", hurt a lot, where it went from $20k to $14k - I was close to buying the new rig, I was actually trying to move my BTC from my wallet to Luno so I can sell it - and I saw that my transaction fee was huge, the fee was something like ZAR 1600+, I just couldn't spend it - so I decided to keep holding until Lightning was implemented, and now it dipped - hard :( So I'm still left holding the bag.
I was hurt by these fees, so damn much that I couldn't get my cash out - and I realised how bad it is, I also realised that at the very least Segwit2x could've been implemented to relieve some of this (or atleast minimize the effect), but it just didn't get implemented and I feel that it's disgusting, do they not realise by ignoring the original 'Peer to peer cash system' use-case that some people are getting very hurt through this? I mean - what's the point in a "decentralised" currency if it can be controlled by a central authority (blockstream) - and they hurt the consumers, why didn't I just use a bank to store my savings for my new rig, it would sure as hell have hurt alot less (TX fees to send from Bank to computer shop would have been around ZAR 6 ffs).
Now, I know this is longwinded, but I would like to apologise for thinking every BCH supporter is an idiot/liescammer, the only thing I can say is that I didn't understand it - I didn't understand what you guys were so upset about, until now - and I feel terrible for the few downvotes I made, I feel sorry for saying something like "don't support evil people" when the BCH crowd is trying to keep BTC from collapsing. I feel terrible about it, I really do.
I hope you guys can forgive me, I truly do - I will try my best to educate myself and help others, I will make it my mission. The only thing I ask now of the BCH community, is if someone knows of an easy/cheap/safe way to exchange my BTC for BCH, without those huge TX fees, I am sorry to ask, I know I don't deserve your help, but I'm desperate and running out of time, I'm starting to feel the pressure and I need to get rig x2 up as soon as possible, before life becomes even more uncomfortable.
Thank you for taking the time to read my apology.

Giveaway and infos about NAV and the 3 soon to be released Nav Coin developments: Valence, Community Fund & Cold Staking

Hi /CryptoCurrency
EDIT: Alright my friends I'm off to sleep now. But if someone decides to download NavPay and post the wallet I might still send him some NAVs tomorrow evening :P
I am a fan of NAV and I would like anyone of you to take a look at NAV Coin and what better way is there to do this with a giveaway so everyone can see for themselves how fast and easy NAV Coin is.
Additionally to the giveaway I want to give the interested ones of you some more infos & teasers about NAV and what I think makes it unique and valuable.

1. Giveaway

First the info about the giveaway so that the people who are only here for the free money don't have to scroll down a wall of text... I won't judge you - you do you! :-P But maybe some of you guys will come back later to read more about NAV after you see how nice the mobile wallet of NAV is.
To get some free NAVs, all you have to do is the following:
  1. Download the app NavPay from the Android Play Store
  2. Follow the steps to set up your mobile wallet
  3. Backup your private key (the random words) so you could restore your wallet if you phone breaks or sth. like that!
  4. Post your public address as a comment in this thread, so I can send you some NAVs
If you liked the experience, I'd be happy to hear back from you :) In the next 2 hours, I'll be giving away NAVs worth about $200 in total (but split up of course, so that everyone will get some to try out the mobile wallet NavPay etc.).
Some additional links:
Thats all for the giveaway, now follows the additional infos.

2. Additional Infos about NAV

Nav Coin has been publicly traded since mid 2014. It's a decentralized cryptocurrency which is built on the latest version of Bitcoin Core with many additional features and functionalities which differentiate Nav from other cryptocurrencies. I'm going to dive into the details of these features later on in this post.
The aim of Nav Coin is to simplify cryptocurrencies. In my opinion, this (the mainstream-adoption) is one of the most important topics for all cryptocurrencies in general. Nav is directly adressing this issue by providing very easy to use tools (wallet, mobile wallet, etc.).

2.2 Facts & Figures

2.3 Team

The team was recently expanded and consists now of the following people.
More infos and links to linked in about the core team is found on the first page of the official NAV website (just scroll down a bit).

2.3.1 Core developer contributors

2.3.2 Core content contributors

2.3.3 Community developers

Since NAV is open source and the core team is encouraging the community to contribute to NAV, there are many more people working on NAV like sakdeniz who is creating a second desktop wallet, slothmike who is working on a reddit tipbot or Prodpeak who is developing an alternative block explorer.

2.3.4 Weekly updates

The core team is releasing weekly updates about the ongoing projects on their website so that anyone interested can see the current status of the roadmap items.

2.4 Main Features

2.4.1 Optional Private Payments

With Nav Coin you have the ability to send private payments. The privacy is optional so you can choose to send non-private or private payments. Nav Coin uses a different approach to achieving privacy than other coins. Nav uses the so called NavTech. NavTech is a dual blockchain system. Essentially, the transaction information is encrypted, split in smaller transactions and sent through a second blockchain, which completely breaks any links between the sending and the receiving address. If you're interested in this technology, you can find the whitepaper on the official NAV website.
At the moment, private payments are processed by trusted servers. Everyone can operate a server themselves or can use the existing ones. The team is working on NavTech 2.0 'Rimu' which will make these servers obsolete, since every wallet will act as a private payment processor which will further push the decentralization.

2.4.2 Proof of Stake

Nav Coin uses the consensus model Proof of Stake which lets holders of Nav Coins earn a reward of 5% in interest of the coin they stake. Staking coins is very simple, you just have to have the wallet open and running.
5% rewards also mean, that there is an inflation of maximum 5% per year. But it is actually lower (at around 2-3%) since not all coins are staking. So if you are staking, you will earn more than the yearly inflation.
Here is a very detailed article about how Nav Coins Proof of Stake works.

2.4.3 Fast transaction times

Nav Coin has a really fast block speed. Transactions are confirmed as spendable withing only 30 seconds which makes it ideal for retail and e-commerce which in my opinion is one of the main points in real-life adoption. There was a video posted recently on the official twitter account which shows how NAV was used to purchase groceries in a store in Rome... That's real-life adoption!

2.4.4 NavPi

Like mentioned above, Nav Coin uses a Proof of Stake consensus model. Most of us have read about the immense energy consumption of Bitcoins Proof of Work model. In my opinion, this is not feasible for the future. With the PoS model of Nav Coin, you can stake your coins on a Raspberry Pi which uses only about 18kWh of power annually if run 24/7! This is much more environment friendly!
Nav Coin even sells their own preconfigured and ready to use NavPi Stakeboxes. Since they're out of stock very fast every time, you can create your own NavPi by following the step-by-step tutorial of the community member navtechservers

2.4.5 Community Fund

Since Nav Coin did not have an ICO or premine, they're fully self financed at the moment. The community has voted for a community fund which will propel the development and marketing of NAV greatly.
When the community fund is implemented, the PoS reward will be reduced from 5% to 4% per year. Each block will generate 0.25 Nav which will be allocated for the community fund (about 21'600 Nav per month).
Both the Nav Coin Core team and the community will be able to propose projects and budgets which the community (the stakers) will vote for. The payouts happen when everyone votes that the work is completed. The aim of this is to fund the development and ongoing success of NAV. You can read more about it here.

2.4.6 NavPay

NavPay is NAVs mobile wallet. It's one of the first mobile wallets that allows private payments. There are already real world merchants accepting Nav thanks to the NavPay app like Pasticceria Piemontese in rome and you can even pay for a cardiologic examination using Nav.
NavPay has a very simple and beautiful user interface. Download it for this giveaway and take a look yourself!

2.4.7 NavChange

Using a combination of lightning network transactions and exchange integrations, NavChange will be a Valence-powered application which facilitates instant exchange between NAV and other currencies
NavChange is a feature which is planned to be launched in 2018.
Here is an example of how it is possible to send Bitcoin anonymously with Nav Coins NavChange.
For the traders: NavChange will greatly increase the volume for Nav.

2.4.8 Valence Plattform (Anonymous Distributed Apps)

At the moment, Nav Coin is "just" a currency. But this is going to change in 2018. The team is in the latest phase of finishing the whitepaper of the Valence Platform which will enable the development of Anonymous Distributed Apps Platform (aDapps) (think of Ethereum's smart contracts, but with privacy!). Valence is a platform that gives developers and businesses a new set of tools to help them realize their ideas on the blockchain. The whitepaper is probably coming in the next 1-2 weeks!

Final thoughts

There are some people who will say that NAV tries to do too many things. I don't agree with these guys. I think this is the main point that speaks for NAV. NANO might be faster (even tho NAV is almost instant as well), XMR might have better privacy (used by Monero fans but never really proven), ETH might have a more accepted dApps platform (we'll see what the whitepaper brings)... but who combines all of these features in one project?
NAV is a jack of all trades.
Thanks for reading this far and now post your NAV public address so I can send you some NAVs! :-D

We need to figure out how to help newbies store and use their bitcoin safely

This is how I do it:
BACKUP:
master private seed words on paper , saved securely.
REGULAR USE:
Preparation: Created a USB bootable linux , install electrum on it , disabled its internet/networking (IMPORTANT!), put private keys in electrum wallet, copy public keys from electrum wallet to usb drive. Boot to regular OS (windows/mac) , open electrum, create watching only wallet with public keys saved on USB.
Using: Create transaction in electrum on regular OS -> save transaction to file on USB . Boot into usb linux -> load transaction from USB in electrum -> sign it, save to USB -> boot to regular OS -> load singed transaction from USB in electrum -> Broadcast!

Add encryption and passwords to the above, and I think its a fairly bullet proof method of storing bitcoins. The private keys are never exposed to any network. I struggled at the part of disabling internet, but it worked out in the end.
Obviously, this process is hard for the average joe. He will just keep his coins on some web wallet, defeating the point of bitcoin, and set themselves up to lose their btc down the road.
There really need to be a method to make this easier. Maybe a modified version of ubuntu, with no networking, encryption and electrum preinstalled ? There is trezor , but I don't have knowledge there. Comments?

The History, The Current State And The Future Of NavCoin

The History, The Current State And The Future Of NavCoin

This is it. If you're interested to see what NAV is all about, this is the ultimate guide for you. You will learn about the history of NavCoin and how it evolved. You will learn about the current state and features of NavCoin and you will learn about the exciting new features that are planned and coming up in the (near) future.
So buckle up, this is going to be a long ride!

Table Of Content


Introduction - What is NavCoin?


The History

Introduction
The following chapter will summarize and break down the history of NavCoin in a few sentences. NAV started a long time ago, went through rebrandings and changes of the core team before it became what it is today.

SummerCoin
NavCoin was initially first introduced under the name SummerCoin on April 23 in 2014. SummerCoin was a fork of the Bitcoin blockchain. It used to have a PoW/PoS hybrid algorithm with a block time of 45 seconds.

SummerCoinV2 /NavajoCoin
Soon after the initial launch of SummerCoin, the original developer left and SoopY (soopy452000 on bitcointalk) took over as the main developer and rebranded the project to SummerCoinV2 respectively NavajoCoin and introduced new features.
The name NavajoCoin was chosen in honor of the Navajo Code Talker. The unbreakable Navajo code was used to encrypt highly classified military information and commands and decrypt the same in WW II.
SoopY introduced a technology which allowed sending transactions anonymously and private. This technology was called "Navajo Anonymous Technology". SoopY also released a new wallet and set the Proof of Stake rewards at 10% for the first year, 5% for the second year and 2% for every year after.

NavCoin
On August 12, 2014, Craig (current lead core developer, pakage on bitcointalk) started to get involved with NAV by helping to set up a website [10].
It was officially announced that Craig joined the core team as a "Wallet & Web Developer" on November 06, 2014.
The last tokenswap and restart of the blockchain of NAV happened on May 12, 2016.
Soon later, SoopY stopped showing up and Craig stepped into the role of the lead core developer. Since then, Craig has assembled a strong team with which he built NavCoin into what it is today.
Currently, Craig and the NavCoin Core team is located in New Zealand and they are actively developing many ground-braking features which differentiate NAV from other cryptocurrencies. You will read more about that later in this article.

The Current State

Introduction
The year 2018 has been a thriving year for the NavCoin ecosystem. Despite the USD price of NAV not reflecting it, in 2018 the core team has developed a whole bunch of new features. Also the core content creators published the first official guidelines that function as an orientation guide for community content creators. This chapter will give you an overview of the current team, the features, the prior mentioned guidelines and the community of NavCoin.

Core Team [1]
Last year, the core team has grown alot. It contains of developers, content creators and interns. The core team are employees of Encrypt S, the New Zealand's leading blockchain R&D lab. Encrypt S is developing blockchain solutions since 2014 and values building open-source software highly.

Craig MacGregor - Chief Executive Officer
Craig is the CEO of Encrypt S and the founder of NavCoin. He is one of the world's most experienced blockchain developers. Craig founded NavCoin in 2014 and is developing software for it since then. He has assembled a strong team of like-minded people. Craig also speaks at seminars and conferenced. Some of the companies and conferences he did blockchain education sessions at are Oracle, Xero, Air New Zealand, Blok Tex and trademe. Together with the team, he is also doing a education series on YouTube where he explains upcoming features in-depth for the community.

Alex Vazquez - Chief Technical Officer
Alex is the CTO of Encrypt S and the most active contributor to the NavCoin core Github. He has incredible knowledge of blockchains and proposes and implements solutions for challenges and features. He supports community developers frequently and answers any questions of the community thoroughly. Like Craig, Alex is developing software for the NavCoin ecosystem for a very long time. Alex speaks at universities at times and educates students about the blockchain technology.

Paul Sanderson - Lead Software Engineer
Paul is the Lead Software Engineer at Encrypt S. He has a flair for technology. His technical and management skills are perfectly suited for consultancy and investment advising. He also frequently contributes to the NavCoin core source code.

Rowan Savage - Senior Software Engineer
Rowan is a full stack software engineer with more than a decade experience in developing complex front-end web applications. He joined Encrypt S in February 2018 and has since been involved in the Valence Plattform, the Kauri Wallet and NavCoin Core. You will read more about these feature/projects later.

Carter Xiao - Lead UX/UI Designer
Carter specializes in user-centric design and is also very talented with 3D animation, motion graphics and programming. One of NavCoins core principle is "Simplifying Crypto" and UX/UI is a very important part of that.

Matt Paul - Software Engineer
Like Rowan, Matt is a full stack Software Engineer. He joined the core team in Mai 2017 and has since worked on NavPay, NavPi, the Kauri Wallet and NavCoin Core. Kieren Hyland - Chief Strategy Officer Kieren is one of the employees that are working for Encrypt S for a very long time. He is the CSO and is a digital strategist and growth hacker with a passion for new technology and has a lot of experience in online marketing. Laura Harris - Creative Director Laura has a combination of commercial and creative flair. She manages the social media accounts for NavCoin and ensures, that NavCoins' message is always powerful, relevant and distinctive. John Darby - Content Creator John is an internationally awarded Technology and Financial sector marketing communications specialist. He is one of the Core Content Creators for NavCoin.

Features of NavCoin [2]
The following features are currently available and have been developed in the last months and years. It is sorted from newest to oldest.

Static Block Reward
The soft-fork for the enabling of static block rewards have been accepted and became active recently at 5th January 2019. This means, that the block reward was changed from a percentage based reward to a static reward. This will incentivize the stakers to have their node online 24/7 which increased the security of the network. It also aligns NavCoin with the PoSv3 specification. With this implementation, the yearly inflation will be 3.6% currently and will exponentionally decrease because of the static value of the rewards. Every staked block will now give the staker 2 NAV. Depending on how many people are staking, the yearly percentage varies. With the network weight currently being around 20'000'000 NAV, stakers earn around 10% rewards from staking 24/7.

Cold staking
To provide extra security to participants in the staking process in the NavCoin network, the core team decided to implement cold staking. This allows to store NAV offline and still be able to sign staking inputs. Looking forward, a possible integration into the Ledger Nano S would mean, that one can stake NAV securely from a offline hardware wallet. How cool is that?

OpenAlias
One of the core principle of NAV is to simplify cryptocurrencies. Many non-technical people are deterred from the long, cryptic addresses used in wallets. When sending funds, you have to make sure that every single letter and digit is correct which is nerve-wracking for the average person. NavCoin has implemented OpenAlias, which allows to transform the wallet address into a email-like form. Everyone can register a name like "[[email protected]](mailto:[email protected])". Funds can then be sent to this name, which makes sending crypto much easier and less error-prone.

Community Fund
This is the one big feature I was most excited about. NavCoin core has implemented the first fully decentralized community fund. Acceptance of proposals and release of funds is all approved by the decentralized network. No central authority has access to the fund. The community fund enables everyone to propose their ideas to the NavCoin community and to get paid to implement these ideas. Everyone can propose whatever they like (of course there is a higher rate of success if the proposal contributes to the NavCoin ecosystem ;-)). In fact, this article was sponsored by the NAV-Community by voting "yes" for my proposal. The fund works like this:
For a fee of 50 NAV, everyone can create and present his idea/proposal to the entire NavCoin network. The fee is here to help prevent spam attacks. Proposals can literally be anything - be it development, marketing or anything else you can some up with.
After creating the proposal, everyone contributing to the NavCoin network can then decide if they like the proposal of not. They vote with "Yes" or "No" for the acceptance of the proposal. Voting happens via staking. Every transaction that gets validated by you gives you one vote. This means that the more NAV you are staking, the higher your voting weight is.
The proposal stays in the state "Pending" until it is accepted or rejected. To be accepted, a proposal has to have a participation of at least 50% of all staked blocks and at least 75% of these votes have to be "Yes"-votes. Like-wise to be rejected a proposal need 50% participation of the network and 75% of these votes have to be "No"-votes. Additionally, if a proposal didn't pass after 6 voting cycles (about 6 weeks) it is also rejected.
After a proposal has been accepted, the creator of the proposal can start his work. When the work is finished, or at in the proposal defined checkpoints, the proposal creator can create a payment request for the full or part of the requested funds.
The NavCoin network can then again decide, if the work is what the creator promised to do and vote for the funds or reject the payment request because it was not what he promised. This mechanism ensures, that the funds are only release if the creator of the proposal did what he promised. The NavCoin network decides everything, there is no central authority which makes the community fund 100% decentralized.
The community fund is quite new but there have already been some proposals that were accepted like paying for the development & hosting of NAV block explorer, the creation and distribution of NAV car stickers to the community for free (or paid by the community fund), the funding of interns for NavCoin Core, translation of the website into other languages and YouTube videos. What ideas could you come up with? By the way: this article was also sponsored by the community fund :-)

Proof of Stake
Like said before, NavCoin uses the Proof of Stake algorithm to create and validate blocks. Participants of the NavCoin network can earn rewards by putting their coins to stake and thus validating blocks and securing the network. The reward used to be 4% fixed but recently changed with the implementation of PoSv3. Currently, rewards for stakers that are staking 24/7 is about 10% but it is dependent on how many people are staking. If more nodes come online, this reward will go down. If 90% of all NAVs would be at stake, stakers would still earn 4%.

Tutorials And Guidelines [3]
The NavCoin Core team pushes the community to contribute to the NavCoin ecosystem constantly. They emphasize that NavCoin is an open source project and everyone can contribute. The team tries to make it as easy as possible for the average person to contribute and thus created different tutorials and guidelines.

Tutorials To Contribute To The Website
The whole website is open source. Everyone can contribute to the website. The team created different guides for people to follow [4].

The NavCoin Developer Manifesto
The content creator core team has build a developer manifesto. It defines the values that should be uphold like for example that they will always operate in the best interest of the network. If defines the principles, purposes, scope of involvement and operational requirements [5].

The NavCoin Content Creation Manifesto
Similar to the developer manifesto, there is also a content creation manifesto. Again it defines the principles for creating content, the purpose, the scope of involvement and the operational requirements [6].

NavCoin Brand Guidelines
In addition to the content creation manifesto, there is also a brand guideline booklet. This should help content creators to create images, videos, articles etc. in the same style as the core team. It defines the NAV brand. The brand guidelines contain definitions, the language to use (words to use, words not to use), the tone of voice, what the community aspires to be and what we discourage to be. It also contains the logo pack which can be used in graphics etc. It describes correct logo spacing, logo placement, the colors of NAV and different web assets. It gives tips about gradients and overlays, the typefaces (with a font pack) and many more. Check it out yourself [7].

NavCoin Educational Series
The core team has decided to actively involve the community in the creation of new features. For this reason and to allow users to ask questions, they created the NavCoin Educational Series. The core team schedules an online live meetup which can be joined by everyone. On YouTube they do live-streams and explain upcoming features. Examples of these series are explanations for cold staking, static rewards (PoSv3) and the community fund. The community can ask questions live and the core team will answer them immediately.

Community
During the last year there have been an influx of software developers from the community starting to create features for NAV.

navexplorer.com
An examples is navexplorer.com which is programmed by community developer prodpeak and is a block explorer for NavCoin. Additionally, it functions as a interface to see what is going on in the community fund. It shows pending proposals and payment requests.

NEXT Wallet
The NEXT Wallet is an alternative wallet for NAV and other cryptocurrencies. It has a beautiful user interface and is additionally the easiest interface to interact with the community fund (create proposals, create payment requests and vote for proposals and payment requests). It is programmed by community developer sakdeniz who put hundreds of hours into it during last year.

There were also some marketing activities starting to emerge with the release of the community fund. Some of these were for example free stickers for everyone in the NAV community to stick to their car / shop / window etc. or YouTube videos of CryptoCandor and Cryptomoonie that explained the details of NAV. I am sure, that with the 500'000 NAV available in the community fund per year there will be an influx of gread ideas - development as well as marketing activities - that will be funded.

The Future

Introduction
These features are planned for the future. Many of the following features are part of the 2019 roadmap. Some will not be described in great detail because not much is known about them yet. I've still listed them as they are part of what is yet to come.

Features
Rimu - Improved Privacy Solution
NavCoin used to be a optional privacy coin. That means, that you could choose to send a transaction in private. NavCoin was criticized for the way it handles private payments because it relied on a few servers which didn't make it that decentralized. The technology was called "NavTech" and was a secondary blockchain that obscured the transaction and the amount that was sent. NavCoin Core is currently developing a new improved privacy solution that will make the private payment system completely trustless and districuted and runs at a protocol level. Alex of the NavCoin Core team has published a paper that describes this new privacy solution. It's called Zero Confidential Transactions and can be found here: https://www.researchgate.net/publication/330366788_ZeroCT_Improving_Zerocoin_with_Confidential_Transactions_and_more. What I want to highlight is the collaboration between Alex as the proposer of the solution and the Veil team, a Bitcoin Core developer and Moneros main cryptographer as reviewers. When the best work together, it will be interesting to see what the outcome is!

Valence Plattform [8]
Valence is an applied Blockchain platform that can help businesses realise the tangible benefits of blockchain. You can think of Valence as a platform with which you can build Anonymous Distributed Applications (aDapps) with. But Valence is a different kind of platform that enables developers to create new types of blockchain applications. The problem with current (turing complete) dApp platforms are their complexity and rigid nature. Security holes in smart contracts and scaling issues happen frequently [9].
Valence provides transitional pathways that let businesses migrate only part of their activities to the blockchain without having to restructure their entire business model [9].
Valence will provide a spectrum of blockchain application solutions which sit along the decentralized spectrum, offering businesses simple ways to dip their toes into the blockchain at minimal risk or complexity [9].
Thanks to the proof of stake nature of the Valence blockchain, more of a node's resources can be used for processing and routing application data which makes the platform faster and scalable.
Valence aims to make building blockchain applications as accessible to the general public as WordPress or Squarespace has made building websites.
The developers NavCoin and Valence aim to make Valence extremely easy to work with:
A Valence application could be an open source mobile or web application that submits unencrypted or encrypted data directly to the blockchain. The only configuration necessary for the app developer would be setting up the data structure. Once they've done that they can start writing to the blockchain immediately.
The Valence blockchain interface is language agnostic, meaning developers are free to build applications in whichever language they're familiar with, which greatly reduces the barrier to entry.
As the platform progresses, Valence will introduce more and more smart contract templates in collaboration with the development community. These will be like plugins that users can simply select and configure for their application, without having to reinvent the wheel and risk contract errors or spend countless hours of research to program them.

NavShopper
The following information is taken from the latest weekly news: NavShopper is a new project which will allow people to spend NavCoin on a growing list of retailers and service providers. NavShopper sits between traditional retailers accepting fiat and NavCoin users and purchases products on behalf of the user by managing the crypt-fiat conversion, payment and shipping. This project will unlock many more ways for people to spend NAV on existing websites/marketplaces without requiring each site to individually accept cryptocurrencies. Some of the prototypes we are working on include crediting your Uber account, buying products on Amazon and donating to charities.

Kauri Wallet
The Kauri Wallet aims to be an open-source, multi-currency wallet which functions as a foundation for other features.

Kauri Enhanced
Enhancements to the Kauri Wallet will allow multiple accounts, pin numbers, recurring payments and more.

Kauri DAEx
The Kauri DAEx is a Decentralised Atomic Exchange that utilises the features of the Kauri Wallet and enables users to create safe peer to peer atomic exchanges for any currency supported by the Kauri Wallet. NavDelta NavDelta will be a payment gateway that allows users to spend NAV at any business which accepts currencies supported by the Kauri Wallet. NavMorph NavMorph is a fusion of Rimu and Kauri DAEx and will allow to privately send every cryptocurrency supported by the Kauri Wallet.

Outro

If you have made it this far: Congratulations! You have learned about how NAV evolved, what its current state is and what the future will bring. To sum all up: NavCoin has made incredible progress during last year and released many long awaited features despite the bear market. Many more exciting features are yet to come and it's going to be very interesting to see where we will stand on this day next year.

Giveaway

Unfortunately, the giveaway was not possible in the cryptocurrency-subreddit because of their rules, so I'm doing it here :-) As a surprise, in the next few hours I am going to send some NAV to everyone who wants to try out the awesome features you have read about above.
To get your NAVs, all you have to do is the following:
If you liked the experience, I'd be happy to hear back from you :)
