A Bitcoin wallet is as simple as a single pairing of a Bitcoin address with its corresponding Bitcoin private key. Such a wallet has been generated for you in your web browser and is displayed above. To safeguard this wallet you must print or otherwise record the Bitcoin address and private key. It is important to make a backup copy of the private key and store it in a safe location. This site does not have knowledge of your private key. If you are familiar with PGP you can download this all-in-one HTML page and check that you have an authentic version from the author of this site by matching the SHA256 hash of this HTML with the SHA256 hash available in the signed version history document linked on the footer of this site. If you leave/refresh the site or press the "Generate New Address" button then a new private key will be generated and the previously displayed private key will not be retrievable. Your Bitcoin private key should be kept a secret. Whomever you share the private key with has access to spend all the bitcoins associated with that address. If you print your wallet then store it in a zip lock bag to keep it safe from water. Treat a paper wallet like cash. Add funds to this wallet by instructing others to send bitcoins to your Bitcoin address. Check your balance by going to blockchain.info or blockexplorer.com and entering your Bitcoin address. Spend your bitcoins by going to blockchain.info and sweep the full balance of your private key into your account at their website. You can also spend your funds by downloading one of the popular bitcoin p2p clients and importing your private key to the p2p client wallet. Keep in mind when you import your single key to a bitcoin p2p client and spend funds your key will be bundled with other private keys in the p2p cl Continue reading >>

How To Steal Bitcoin In Three Easysteps

How To Steal Bitcoin In Three Easysteps

And once youve stolen it, how do you unload it? Earlier this month, someone pulled off the largest heist in the history of Bitcoin, the virtual currency that approximates cash on the internet. The illegal drug bazaar Sheep Marketplace was plundered, either by hackers or insiders, and about $100 million worth of the currency was stolen from customers. Bitcoin heists are actually not uncommon. In June of 2011, a user named Allinvain was the victim of what is arguably the first recorded major Bitcoin theft. Allinvain awoke to find that a hacker had stolen about half a million dollars worth of bitcoins. I feel like killing myself now, he wrote at the time. There have been dozens of Bitcoin thefts since then. The supposedly high-return investment fund Bitcoin Savings & Trust turned out to be a pyramid scheme, its owner charged with ripping off investors for $4.5 million in bitcoins. MyBitcoin, a wallet service that stored bitcoins like a bank account, disappeared with about $1 million worth of users bitcoins. Several of the most trusted and well-known Bitcoin companies, including the Mt. Gox and the now-defunct Bitcoinica exchanges, have also suffered high-profile thefts. Victims of credit card theft can cancel a card or reverse fraudulent transactions, but Bitcoin is attractive to thieves because its transactions are irreversible. Bitcoin is like cash, says Nicolas Christin, an assistant research professor at Carnegie Mellon University who has done extensive analysis of Bitcoin. The only way to get it back is by tracking you down and basically beating you up with a lead pipe. But like all things Bitcoin, its difficult to understand exactly how digital theft works. What are you stealing, exactly? And once youve got it, what do you do with it? There is no such thing as a Bit Continue reading >>

Security - Creating A Fake Transaction - Bitcoin Stack Exchange

AttackerAlice has a BTC Wallet with 0 BTC.AccompliceBob has a BTC Wallet. Is it possible to transfer 100 BTC from AttackerAlice to AccompliceBob? Suppose a BadMiner accepted this as a valid transaction, and puts this fake transaction into a block, how will it be detected and rejected? to add to the question... Also if the BadMiner is able to create an additional block, will en.bitcoin.it/wiki/Protocol_rules be enough to keep the offending blocks out of the blockchain? Smagula Jan 31 '14 at 11:47 You can create fake transactions and blocks including fake transactions all day long if you want. Your problem would be getting other people to accept those blocks and they won't because they can very easily see that it contains fake (better word: invalid) transaction(s) and simply disregard those blocks completely. The first invalid block wil never be accepted by any non-accomplice so it doesn't matter how many blocks are put on top of that, they won't be accepted either. got it.. since most of the network would have rejected the first block, the blockchain will not have the fake block.. other miners intending to add to the block chain will not see the fake block in majority of the cases... hence the honest block chain will grow faster and survive.. Smagula Jan 31 '14 at 12:32 actually it's better to say that nodes won't relay the transactions, nor include them in their block in the first place. Luca Matteis Jan 31 '14 at 14:05 This cannot happen because of the way each transaction is designed . Every single transaction must reference an output of another transaction. Essentially you can only spend the money that you already have. You cannot create BTC out of thin-air. The consensus algorithm is programmed in all nodes to only create coins out of thin-air based on the coinbase Continue reading >>

By Reading This Page, You Are Mining Bitcoins Quartz

If you clicked the button above, then you are currently mining bitcoin, the math-based digital currency that recently topped $1,000 on exchanges. Congratulations. (It wont do anything bad to your computer, we promise.) New bitcoins are created roughly every 10 minutes in batches of 25 coins, with each coin worth around $730 at current rates. Your computerin collaboration with those of everyone else reading this post who clicked the button aboveis racing thousands of others to unlock and claim the next batch. For as long as that counter above keeps climbing, your computer will keep running a bitcoin mining script and trying to get a piece of the action. (But dont worry: Its designed to shut off after 10 minutes if you are on a phone or a tablet, so your battery doesnt drain). Lets start with what its not doing. Your computer is not blasting through the cavernous depths of the internet in search of digital ore that can be fashioned into bitcoin bullion. There is no ore, and bitcoin mining doesnt involve extracting or smelting anything. Its called mining only because the people who do it are the ones who get new bitcoins, and because bitcoin is a finite resource liberated in small amounts over time, like gold, or anything else that is mined. (The size of each batch of coins drops by half roughly every four years, and around 2140, it will be cut to zero, capping the total number of bitcoins in circulation at 21 million.) But the analogy ends there. What bitcoin miners actually do could be better described as competitive bookkeeping. Miners build and maintain a gigantic public ledger containing a record of every bitcoin transaction in history. Every time somebody wants to send bitcoins to somebody else, the transfer has to be validated by miners: They check the ledger to ma Continue reading >>

Beware Of These Five Bitcoin Scams

Beware Of These Five Bitcoin Scams

By Dan Blystone | April 23, 2015 1:37 PM EDT As consumers'adoption of bitcoin continues to increase and a number of major retailers have decided to accept the virtual currency, alarming cases of fraud with bitcoins continue to emerge. Because bitcoin transactions are irreversible and not overseen by a central authority or bank, bitcoins are a popular vehicle for fraud and theft. Bitcoin scams are often initially promoted in online forums or chatrooms, with promoters creating an elaborate front to convince investors they are legitimate. The following are five of the most common scams involving bitcoin: 1. Bitcoin Ponzi Schemes and High-Yield Investment Programs. These scams lure people in with promises of high interest rates on deposits. As with other Ponzi schemes , early investors are paid out using investments from later investors. When new investors stop joining and payments cannot be made, the scheme collapses. These scams last often only a couple of months, but the organizers are prone to simply repeat the whole process again afterwards. 2. Bitcoin Mining Investment Scams. Bitcoin mining involves validating transactions and providing security for the public ledger, known as the blockchain . This process requires extremely powerful and expensive computer equipment. The mining scams typically involve orders for equipment that are paid for in advance and never delivered. (For an in-depth review of mining, see: What is Bitcoin Mining? ) 3. Bitcoin Wallet Scams. A bitcoin wallet is a software program used to store bitcoins. Wallet scams attract users with the assurance of greater transaction anonymity. Once the deposit level rises above a certain level, the scammers simply move the bitcoins into their own wallet. 4. Bitcoin Exchange Scams. These exchanges attract users Continue reading >>

How To Spot A Bitcoin Scam

How To Spot A Bitcoin Scam

Opinions expressed by Forbes Contributors are their own. Whenever something gets hot, the only guarantee is that scamsters will lock onto it like a heat-seeking missile. The virtual currency bitcoin is no exception. For those living off the grid, bitcoin is a digital currency. Its value, not backed by any government or central bank, is determined by software that few people truly understand. Since few know how bitcoin really works, there have been endless opportunities for chicanery. Social media has provided fertile ground for numerous frauds. Naturally, those who want to speculate in bitcoin want to believe that the currency's value will do nothing but go up in value, but that hasn't been the case. The currency is very volatile and few understand why. According to a recent report by Zerofox , a digital risk monitoring company, there's a considerable dark side to bitcoin. Here are some ways to spot scams: -- Malware downloads. Bitcoin is often used as "bait" to get you to download some nasty software that will mess up your computer. According to Zerofox: "Fake bitcoin 'wallets' hiding malware downloads: Attracting users to click through URLs posted to social media is a technique that ZeroFOX has observed in a variety of attacks. This one uses the promise of bitcoin to lure the user into following a URL that subsequently attempts to download a malware-laden app. We also discovered that fake bitcoin surveys are often used to distribute malware, and we advise caution when encountering any social media URL that is either shortened or not secured with an HTTPS connection." -- Bitcoin phishing impersonators. "Impersonators run rampant on social media, and impersonating the bitcoin brand itself is a tactic that can be used to gain a victims trust and credibility. A phishing Continue reading >>

Create A Bitcoin Transaction By Hand

Create A Bitcoin Transaction By Hand

I guide you through creating a Bitcoin transaction manually, step by step, without overloading your brain with much explanation. Andreas Antonopoulos mentioned once if he would be in prison he would reinvent an offline version of the Bitcoin consensus algorithm by playing Sudoku. Doing a role-playing like thison Bitcoin meetups makes a lot more sense than you would initially think, let me explain why. InAndy Hunt's book, ThePragmatic Thinking and Learning he told a story of how he learned wall climbing. First he paid a lot of money for a lesson, then the instructor told the group go climb wall and went for a cup of coffee. After half an hour of climbing the wall and cursing the lazy instructor, it came back and started explaining how to climb the wall. The explanation made a lot more sense after some experience, than it would've mean before that. The reason is because there are two primary way of learning: synthesis and analysis. If you cannot identify which one was which in the wall-climbing class you were not paying attention my dear reader. Role-playing is also asimilar synthetic learning experience. Since playing Sudoku requires people and you are just a loner in front of your screen, I will not go down the role-playing rabbit hole, but instead will arm you with a similar synthetic learning experience. We are going to go through how to construct a Bitcoin transaction with your hand, without deep stuff. Just follow on and it will magically make sense why your wallet software is presenting you so much useless information. This, of course, is primarily important in allowing you to win /r/Bitcoin arguments. And, at the end of the day, isn't that what it's really all about? But also it will provide you a holistic understandingwhat you will unconsciously dig up every tim Continue reading >>

Btc Addresses Whose Private Keys Are From Sha256 Of Another Public Address | Hacker News

Btc Addresses Whose Private Keys Are From Sha256 Of Another Public Address | Hacker News

When a company that I worked at was doing some testing with testnet bitcoins, I thought it would be useful to maintain an office pool based on a brainwallet, so that anyone could just use the testnet coins for experiments, and then send them back to the brainwallet. The passphrase was a dictionary word with a couple of trivial substitutions -- something like "company" => "c0mp4ny!" -- to make it easy for developers to remember for ad hoc testing. After I sent some testnet coins to the address but before I could even send out an email telling people about it, the coins had been stolen (it might have been in the same block that my original transaction appeared in, I don't remember). This was ~3 years ago, and on testnet -- the only thing I could imagine is that someone was testing out a brainwallet-stealing bot on testnet before deploying it to mainnet. I was very impressed. I think a compelling theory is that these addresses are generated by blockchain.info accidentally hashing uninitialised memory instead of random data. Uninitialised memory for blockchain.info would have a very high density of bitcoin-related data, and they also generate a large amount of keys. If they (sometimes?) end up hashing uninitialised memory instead of random data, there's every chance that they'd sometimes generate keys that are hashes of bitcoin-related data. It is admittedly unlikely that they'd be hashing data that is exactly the right length to be a bitcoin address or txid, but there could also be another bug which means they hash data that is nul-terminated rather than a fixed size. Both fitwear[1] (mentioned in the pastebin) and another user[2] have reported BTC inexplicably being transferred out of their blockchain.info wallets. The next question is, if this is really what's going on, Continue reading >>

7 Bitcoin Scams You Need To Be Aware Of

7 Bitcoin Scams You Need To Be Aware Of

As the price of bitcoin has increased substantially over the last few years, so has the number of malicious individuals and organizations looking to take advantage of others in the Bitcoin community. Bitcoin scams are not a new occurrence as they have been around since the currency first gained some popularity. Today, however, there is a broad range of bitcoin scams that are defrauding unsuspecting users. A 2015 research paper by Marie Vasek and Tyler Moore titled Theres No Free Lunch, Even Using Bitcoin: Tracking the Popularity and Profits of Virtual Currency Scams shed more light on the prevalence of bitcoin-related scams, revealing that over $11 million had been lost to scams up to that point in time. In this article, we introduce the seven most prevalent types of scams you should be aware of to avoid falling victim to any of them. Every user requires a bitcoin wallet to store their funds and to send and receive payments. There are four main types of wallets for bitcoin, namely; hardware wallets, web wallets, desktop wallets, and mobile wallets. Scammers, seeing the high demand for mobile wallets, have started to create fake wallets to defraud people. The fake bitcoin wallets usually have a name that is very similar to legitimate and trusted wallets such as Coinbase or Mycelium and, in some cases, even the same logo. These copycat tactics trick the user into downloading it believing it is the legitimate companys wallet. Some fake wallets have crept onto the Apple and Android stores masquerading as genuine wallets. Another way that fake wallets get customers is by promising greater transaction anonymity according to Marie Vaseks and Tyler Moores study : We were able to analyze three of these services (Onion Wallet, Easy Coin, and Bitcoinwallet.in), in which all trans Continue reading >>

Bitcoin Worth $4.7 Million Seized In Fake Id Operation | Fortune

Bitcoin Worth $4.7 Million Seized In Fake Id Operation | Fortune

As law enforcement grows increasingly adept at tracking Bitcoin transactions , federal investigators have seized some $4.7 million worth of Bitcoin in what has been described as a large scale fake ID operation. Thats according to the Associated Pres s , which reports that a district court in Ohio has charged Mark Simon of falsifying identification documents. Authorities seized the cryptocurrencies, along with computers, printers, as well as gold and silver bars inside the home of the alleged fake ID maker. Still, investigators didnt find the alleged ID-makers trail using Bitcoinbut rather using Reddit. Simon was allegedly peddling his goods via Redditleaving a trail leading to a college student who told regulators that a friend bought a falsified ID using the site. The news comes as criminals are gravitating toward other cryptocurrencies such as Litecoin or Monero instead of Bitcoin , as investigators grow more savvy with tracking the poster child of cryptocurrencies. Cryptocurrencies in general are thought to be favored in criminal transactions, as they are pseudonymous and harder to track. Though even with Bitcoin and its peers, the problem of marketing goods is still difficult for those hoping to erase their trail. Continue reading >>
