A community dedicated to Bitcoin, the currency of the Internet. Bitcoin is a distributed, worldwide, decentralized digital money. Bitcoins are issued and managed without any central authority whatsoever: there is no government, company, or bank in charge of Bitcoin. You might be interested in Bitcoin if you like cryptography, distributed peer-to-peer systems, or economics. A large percentage of Bitcoin enthusiasts are libertarians, though people of all political philosophies are welcome.
Not sure if Bitcoin is a currency designed to be somewhat anonymous or private, but in the web it gives lots of advice to protect your privacy while using it, my question is: If they worry that much about user's privacy, what is the purpose of the blockchain and its public record of transactions?
seems that new money is not getting in and im not talking about big institutions im talking about people, fiat was forced upon people,bitcoin wont be. people have to force it upon the government but can we do it? no matter how much i try to explain to my friends what bitcoin is and how it will benefit our generation they just keep noding their heads but nobody bought literaly none of them, my bros that are 7years old and 13 years old are realy in to it and want to buy when they start geting money so what u guys think? is bitcoin gona moon soon or we gona have to wait for 5 to 10 more years for general iq of the population to increase enough so the majority realizes thats what we need
I'd Heard we will be able to assemble a pc in out hideout or so it was rumored... Instead of Physical Bitcoins why not have Scrap Paper with cold storage keys? that way when you get back to your hideout it's like playing the lotto to see how many bitcoin it stored? i know it's too much but just a passed idea.
Hi guys, Please dont take me as FUD creator. I really want this to be a discussion and see the replies from old bitcoin hodlers. We all know that the idea of bitcoin was to be a glabal payment instrument. Now that USA government has classified bitcoin as an asset I really think that the original idea behind the bitcoin is dead. Bitcoin is same as gold now, thats still a great achievement for a crypto currency, but you dont buy your coffee for gold in your local cafe. What are your thoughts about this?
As a BDSM enthusiast I have a Bitcoin idea. Is this possible to do ?
I'm not that technical but I can pay someone to code this. I just want to see if it's possible and would it work. I think it's a niche idea and definitely has a market anyone whos into Bitcoin and is kinky. I want to build a shock collar to be activated when the price drops. Is it doable with raspberry pie somehow as the controller ? I have a budget so if anyone can help pm me.
X-POST from r/Bitcoin: [idea] Simple live bootable ubuntu iso for cold storage wallet
X-POST from Bitcoin. Currently the iso only has bitcoin support, but I have it prepped and basically ready to support ltc and ether. I have spent a few solid weeks on this and want to guage support before spending more time. Let me know what you all think. Hey everyone, I am wondering if anyone would be interested in a live, bootable, iso version of ubuntu which would make creating an air-gapped offline wallet much simpler for the average person? I have one that i consider beta version which boots up and has a pdf with instructions and Electrum already installed and ready to create a wallet. The iso has networking disabled to ensure it is airgapped, so the user does not have to physically unplug it, or if they forget to they are still safe. It has unity hidden so it is simple and basic such that even non-linux users should be able to follow. I chose electrum because you can use seed words and create an online watcher wallet to be able to request money and monitor the balance without compromising the security of the cold storage wallet. Would any of you be interested in that? Are there any tips or suggstions on anything that could be added to make it easier? Thanks!

Hey, me and a developer friend of mine have some time on our hands and want to develop a website or app within a month(within the bitcoin ecosystem of course). Though we have some ideas on our own, it would be great to hear your suggestions/ideas. Let the brainstorming begin! EDIT: I prefer something simple, that is well implemented over an ambitious project, that will have its flaws due to limited manpower and time.

Hidden Nick Szabo paragraphs reveal even more explicitly proto-Bitcoin ideas
Nick Szabo's "Secure Property Titles with Owner Authority" is a fascinating essay describing a "secure, distributed title database" as a way to protect property titles through a public network. It is a must-read for those interested in Bitcoin history, and thus it deserved a place on the Satoshi Nakamoto Institute website. The essay, of course, is a forerunner to the concept of the block chain, and recently many have resurrected the speculation that Nick Szabo is Satoshi Nakamoto. This post is not meant to suggest one way or another if such a speculation is true, but for the sake of Bitcoin and crypto-anarchist history, I'd like to present some hidden paragraphs I found commented out on the essay page while I was uploading.
Confidential Ownership Using a new key pair for each transfer, besides facilitating shared control over property, can also help solve the confidentiality problem, and make it so that servers cannot discriminate against politically incorrect parties. This takes advantage of the "blindfolded justice" effect provided by anonymity. The holder of the unique key can remain anonymous (to some extent, see caveats below) and still transfer the title to others. One could contact the owners if they incorporate remailer-return envelopes with the title. Anonymous property titles would have some other interesting consequences. Let's say there's a public good which nobody has incentive to fund unless they own most of a certain kind of property. (For example, the classic stock market takeover, where only holders of large voting blocks will put in the oversight needed to straighten out management). They could purchase property under different keys without raising suspicion that a takeover is underway. Of course, the same strategy could be used to create monopolies for less useful purposes. If potential users of a property don't know who the owner of the property is, that might make practical enforcement of some kinds of property rights difficult. To enforce Alice's rights, she may have to prove to a jurisdiction that she owns the property. She can prove that the titled owner claims that she owns (not the same thing as proving that she owns, but perhaps good enough for enforcement purposes) by signing her jurisdictional name with the current owner's key. To completely prove that she owns, she would have to transfer the title to her jurisdictional name. (The jurisdiction being the entity that actually physically enforces the property rights, where this is necessary). In either case, it seems she has to reveal her jurisdictional identity in order to enforce her rights. Self-enforcing property protection protocols might allow more anonymity, where these are feasible. Some kinds of property would naturally be associated with some physical location, and thereby not be very anonymous. Furthermore, a mass of transaction detail can accumulate in the public database, revealing unique patterns of behavior. So overall the anonymity is pretty weak even with use-once keys, and may raise problems with hidden monopolies and enforcement. So it would be nice if the servers could be trusted not to block trades even when they know the identities of the owners. In the design I suggested a conspiracy of >=1/4 of the servers can so block. It might also be nice if some sort of blinding/mixing mechanism (a la digital cash) could be introduced to unlink trades between these identities while maintaining the integrity of ownership transfer, so that the public database doesn't reveal so much traffic information. Keeping Servers Honest The two theoretical areas dealing with this are Byzantine agreement (used here) and multiparty secure computation. Some recent work in these areas has been done by:
The Byzantine agreement and related results typically require n>3f. (n is the number of servers and f is the number of maliciously faulty, or "Byzantine", servers that can be tolerated). Multiparty secure comptutions achieve n>2f but assume Byzantine agreement for synchronization, so they have in theory a 3f "security hole". Variations don't always achieve such numbers. The Malkhi/Meiter replicated database achieved only n>4f. (They do have a newer paper I haven't read which may improve upon this by going to "highly probable" security). Under the assumption of digital signatures, agreement can be reached in n > f. This gives the same abstract trust model as the untraceability of anonymous remailers. (Of course, actually getting the message through requires all n remailers to work properly, so in that sense even cf reliability is better than remailers). It would be neat if one could do a replicated database with such a high trust threshold, but I haven't seen anything like that in the literature and there may be good reasons why we can't. Economic security models would be desirable here, but are not ready for prime time. Deciding what the preferences and resources of the attacker should be is tough. Economists assume some typical probability distribution of preferences, and some constant amount of wealth. Cryptographers, and even some people studying fault tolerance, assume a much more powerful and malicious adversary: with polynomial computational resources, and preferring to do the most damage possible to the user. The Byzantine attacker's utility is precisely the negative utility of the user! Economic models tend to look at linear or constant differences (Mallet can't make more money than it costs him to crack the security, so Mallet won't try to crack it) whereas cryptographers prefer super-polynomial differences (the cost to Mallet is super-polynomial in a security parameter controlled by the defender). Economic models bear some similiarity to the "benign" models of statistically distributed error in fault tolerance (as opposed to the "Byzantine" models of maximally malicious faults). However, once security models bubble up to the level of trading off f vs. 2f vs. 3f security, we have the same linear structure as an economic model. So it would make sense to introduce economics at that level of analysis. Economic security ideas like "exposure" make a lot of sense, especially for financial security. An example is the the ATM limit of $300/day: this is the user's "exposure", the most she can lose, to a crack of the ATM system. This is a "knob" which can be adjusted to reflect the current costs of cracking the security. So it would be nice to come up with good theories along these lines at some point. Another nice thing might be a theoretical regime "in between" economics and cryptography, dealing with resource and preference differences within the polynomial range (e.g., O(n4) vs. O(n)).
