Blockchain.info - Is It Possible To Identify A Wallet From An Address? - Bitcoin Stack Exchange

Is it possible to identify a wallet from an address? I want to know is there anyway to identify a particular wallet (its username or email address) on the basis of a Bitcoin receiving address which is generated from that wallet. I am posting that address below: If you've added "blockchain.info" because you know that you generated the address on blockchain.info, you should try to contact the customer support. Murch Jun 27 '17 at 3:08 Bitcoin is what is called "pseudonymous", meaning that a bitcoin address does not reveal information about the owner of that address. Bitcoin addresses (like the one you posted) are derived by using two types of cryptographic operations, elliptic curves and hash functions...both of which only operate in one direction. Even if you could reverse this process for a given address, all you have is a private key. That private key does not contain any information about who generated the key, nor which other keys/addresses are associated with it. There are blockchain analysis techniques that can be performed to attempt to associate a bitcoin address with other addresses (with a variable degree of certainty), but even that will not give you what you are looking for unless you can associate one of those addresses with someone's identity. This would require your query to be supplemented with additional information not found on the Bitcoin blockchain. If you do not possess that additional information, you cannot associate an address with an identity. Continue reading >>

Crypto Trader. Tweet about Bitcoin, Ethereum & Crypto at @BambouClub. Crypto Data Analysis at Blocklink.info Are you in the Bitcoin 1%? A New Model of the Distribution of BitcoinWealth TL DR: If you just want to see the results, they are at my data analysis site Blocklink.info [Please clap for this essay. I tweet about crypto trading at BambouClub ] Previous models of the distribution of Bitcoin wealth all depended on an analysis of Bitcoin wallets and Bitcoin addresses. That approach fails inevitably because of the unknowable relationship between people owning Bitcoin, Bitcoin wallets, and Bitcoin addresses. This is a description of a new model of the distribution of Bitcoin wealth built on the assumption that a universal Power Law applies, and that it mirrors the distribution of global financial wealth as reported in the Credit Suisse Global Wealth Report 2016. The Bitcoin distribution that results is tweaked manually to reflect the great mining rewards paid out in the early years to a few people, making it still less equitable than the highly inequitable financial wealth distribution. An estimate of the Bitcoin-owning population is derived from a survey of traffic to Bitcoin-related websites as reported by Alexa.com in comparison to traffic to sites of popular financial corporations that publish their user numbers. There are two parts to this essay a) why former models based on address analysis failed, and b) the new model. Scroll halfway down if you are uninterested in the first part. A.

Using The Blockchain Trail To Track Stolen Bitcoins

Using The Blockchain Trail To Track Stolen Bitcoins

Using the Blockchain Trail to Track Stolen Bitcoins by Clay Michael Gillespie | Jan 17, 2015 | Bitcoin Security , bitcoin technology , Blockchain innovation , News | 19 comments NEW YORK (InsideBitcoins) Recent bitcoin hacks serve as yet another reminder that bitcoin is still in a nascent state when it comes to security. The blockchain may be a public ledger, but its not as easy to track stolen funds as some people might think. Innovations like mixers and tumblers can move digital currency holdings to multiple bitcoin addresses, allowing privacy-seeking users to obscure their trail. Due to repeated and significant security lapses, governments all over the globe are beginning to consider tighter legislation on cryptocurrencies. According to Fabio Federici , CEO of Coinalytics, if people within the bitcoin community can create tools that help keep users safe from hacks, government regulators might be appeased or perhaps of a mind to invoke less rigorous restrictions. Security and regulation are going to be two big topics this year. Even though the blockchain is secure, vulnerabilities in other spaces, like we have seen with the Bitstamp case, could potentially cause major damage, Federici told Inside Bitcoins. Coinalytics compiles data from the blockchain and converts it into user-friendly analytics. After Bitstamp had been hacked, the blockchain data analysts at Coinalytics decided to plug in available information and visualize the direction of where the coins were heading. I think its good that weve shown that we can handle those issues, he said. Being able to show the regulators that we can deal with the bad actors, that we have tools to track fraudulent behavior and keep the end user safe, is going to put us in a favorable environment. At its core, bitcoin allows ano Continue reading >>

Your Bitcoins Are Easier To Trace Than You Think | Time

Your Bitcoins Are Easier To Trace Than You Think | Time

Bitcoins Are Easier To Track Than You Think Bitcoin is sometimes thought of as the prime anonymous cash of the Internet, believed to be as untraceable as an under-the-table payment to a babysitter or a drug dealer. But the dramatic trial of Ross Ulbricht , a 30-year-old man accused of running the contraband Silk Road marketplace, is finally putting those misconceptions to rest. Federal agents said they were able to trace 3,760 bitcoin transactions over the course of a year to servers seized in the Silk Road investigation, Wired reports. A former FBI agent named Ilhwan Yum testified in court that he followed more than 700,000 bitcoins from the Silk Road marketplace to Ulbrichts personal wallets. When federal agents arrested Ulbricht in San Francisco in Oct. 2013, they also seized his laptop before he could encrypt it. That machine gave Yum access to Ulbrichts bitcoin address, which he then compared against whats called the blockchain, a master list of bitcoin transactions kept to prevent counterfeiting. Comparing the two let Yum track bitcoin transfers from Silk Road servers near Philadelphia and Reykjavik, Iceland to Ulbrichts bitcoin wallet. In Ulbrichts case, the transactions show Ulbricht was trading bitcoins during the same period that his defense attorney said he wasnt involved with the website. But more generally, it shows that bitcoin isnt always as anonymous as its made out to be. Continue reading >>

Top Seven Ways Your Identity Can Be Linked To Your Bitcoin Address

Top Seven Ways Your Identity Can Be Linked To Your Bitcoin Address

You are at: Home Top Seven Ways Your Identity Can Be Linked to Your Bitcoin Address Top Seven Ways Your Identity Can Be Linked to Your Bitcoin Address The key to keeping your Bitcoin transactions from being traced back to you is preventing others from knowing which addresses are yours. If youre trying to remain anonymous (or more precisely, pseudonymous) with Bitcoin, read on for the most common ways peoples true identities are forever associated with their Bitcoin addresses. And try to avoid them. It might also be worth checking out Using Bitcoin Anonymously for other best practices and pro tips. 1. Publishing Your Name and Bitcoin Address Online Who Knows Your Address: anyone on the internet Gary has received over 71 BTC to this address . This is a no-brainer and its the most common way ownership of a Bitcoin address is revealed. Lots of folks on the internet publicly display a Bitcoin address with their name attached to it in hopes that others will send them bitcoins. A few examples: Writing a personal blog with your real name on it and posting a Bitcoin address for donations. Using your real identity on a forum and putting your Bitcoin address in the post signature. Launching a website with your Bitcoin address anywhere on it and registering the websites domain name with your real name. Unfortunately, once published, this knowledge becomes available to anyone with an internet connection. Specific Bitcoin addresses are easy to lookup with a search engine. And thanks to things like Google Cache and The Way Back Machine , it will probably be like that forever. 2. Trading Bitcoins for National Currency on an Exchange Mt. Gox kept tabs. And then they were leaked. Nearly every exchange that handles national (fiat) currency is subject to money laundering regulations, maki Continue reading >>

Bitcoin Owners, You Need To Do These Two Things Rightnow

Bitcoin Owners, You Need To Do These Two Things Rightnow

Bitcoin owners, you need to do these two things rightnow The world has officially gone insane over Bitcoin and millions are rushing to buy it. There are a couple of things that need to be said, now more than ever. Lets get straight to the point. That is the name of the Bitcoin game. Bitcoin works because when it comes to keeping track of who has how many coins or who sent how many coins where, neither you or I have to trust each other, or trust a central entity. It also works because we dont have to trust a central entity, like a bank, to hold our coins. Your coins are yours alone, provided you hold the private key to your Bitcoins. Your keys, your Bitcoin. Not your keys, not your Bitcoin. Time and time again, even the most tenured Bitcoin hodlers have ignored this adage and suffered the consequences. Unsurprisingly, the use of centralized exchanges that facilitate the sales of Bitcoin has coincided with Bitcoins growth and gone parabolic. With this rise in exchange usage, this message needs stressed upon now more than ever. The growth rate of one of worlds most popular Bitcoin exchange grows as Bitcoins does, source: AlistairMilne Theres no measuring just how many people using exchanges to buy Bitcoin are keeping their coins on these exchanges for extended periods of time, short of asking exchanges for the numbers themselves. But as long as that number keeps rising, a larger and larger target is painted on these services backs. The potential damage (or payday, depending on how you want to look at it) from a successful attack on any of the countless crypto exchanges also rises accordingly. For those who dont know, leaving your coins on an exchange does not mean those coins are yours. You are simply trusting the exchange to release them to you at some point if you so re Continue reading >>

Can I Trace A Bitcoin Wallet Owner Using Their Wallet Address? - Updated

Can I Trace A Bitcoin Wallet Owner Using Their Wallet Address? - Updated

Can I trace a Bitcoin wallet owner using their wallet address? You absolutely can. A bitcoin wallet is pseudo-anonymous, not anonymous. If Alice sends a transaction to Bob, and Bob knows Alice was the sender, then Bob will also be able to see all transactions that Alice makes from her wallet. Unlike Bitcoin, crytpocurrencies such as Monero and ZCash are completely anonymous because they mix transacstions together before the receiver receives the final transaction. If you are asking about finding information about the sender without knowing anything about sender, it would be very difficult. You cannot find this users identity. Lets see how Bitcoin system works; No one knows who holds a particular bitcoin address. Its like having a clear plastic wallet with no visible owner. Everyone can look inside it, but no one knows whose it is. However, its worth pointing out that people who use bitcoin unwisely (such as always using the same bitcoin address, or combining coins from multiple addresses into a single address) risk making it easier to identify them online. You can have the same wallet but you can use a lot of addresses. Most digital wallets make a new bitcoin address for you every time you make a transaction. But if you use a public address (for example if you post your address on your e-shop) then its easy to find how many bitcoins are stored in this address. Not your wallet. So, practically, its very difficult to identify a bitcoin user nowadays. I hope you found this information useful. If you have any questions feel free to ask in the comment sections below. Youre my oxygen. I need your feedback to become better. Upvote, Comment, Share. If you visit and type in a BTC public address in their search box it will show you the exact amount of BTC they hold in this publi Continue reading >>

Bitcoin: Irs Uses Chainalysis Software To Id Tax Cheats | Fortune

Bitcoin: Irs Uses Chainalysis Software To Id Tax Cheats | Fortune

One benefit of using bitcoin is the digital currency can be anonymousits owners can move money around the world without revealing who they are. Well, in theory at least. In reality, bitcoin is less secret than people think. The latest reminder of this comes via a report that the Internal Revenue Service is using software to unmask bitcoin users who have failed to report profits. According to a contract unearthed by the Daily Beast , the IRS is paying a company called Chainalysis to help identify the owners of digital wallets that users employ to store their bitcoins. In a letter to the IRS, the co-founder of Chainalysis says the company has information on 25 percent of all bitcoin addresses and that it deploys millions of tags to help track and identify transactions. Here is a screenshot of a paragraph from the letter: The decision by the IRS to license the software of Chainalysis, which is based in Switzerland with an office in New York, appears to be part of the agencys larger campaign to target digital currency users who have failed to pay tax. As Fortune reported earlier this year, the IRS claims only 802 people declared a capital gain or loss related to bitcoin in 2015. This is significant since the price of bitcoin soared from around $13 to over $1100 between 2013 and 2015, and hundreds of thousands (like millions) of Americans bought and sold digital currency during this timein other words, there are many people who face bitcoin-related tax trouble, and the IRS is tracking some of them down.

Address - Bitcoin Wiki

Address - Bitcoin Wiki

A Bitcoin address, or simply address, is an identifier of 26-35 alphanumeric characters, beginning with the number 1 or 3, that represents a possible destination for a bitcoin payment.Addresses can be generated at no cost by any user of Bitcoin.For example, using Bitcoin Core , one can click "New Address" and be assigned an address.It is also possible to get a Bitcoin address using an account at an exchange or online wallet service. There are currently two address formats in common use: Common P2PKH which begin with the number 1, eg: 1BvBMSEYstWetqTFn5Au4m4GFg7xJaNVN2. Newer P2SH type starting with the number 3, eg: 3J98t1WpEZ73CNmQviecrnyiWrnqRhWNLy. Like e-mail addresses, you can send bitcoins to a person by sending bitcoins to one of their addresses.However, unlike e-mail addresses, people have many different Bitcoin addresses and a unique address should be used for each transaction.Most Bitcoin software and websites will help with this by generating a brand new address each time you create an invoice or payment request. Creating addresses can be done without an Internet connection and does not require any contact or registration with the Bitcoin network.It is possible to create large batches of addresses offline using freely available software tools.Generating batches of addresses is useful in several scenarios, such as e-commerce websites where a unique pre-generated address is dispensed to each customer who chooses a "pay with Bitcoin" option.Newer "HD wallets" can generate a "seed" token which can be used to allow untrusted systems (such as webservers) to generate an unlimited number of addresses without the ability to spend the bitcoins received. Bitcoin addresses are case-sensitive. Bitcoin addresses should be copied and pasted using the computer's clipboard w Continue reading >>

Blockchain - Knowing A Single Transaction Can You Track Down A Bitcoin User? - Bitcoin Stack Exchange

Blockchain - Knowing A Single Transaction Can You Track Down A Bitcoin User? - Bitcoin Stack Exchange

Knowing a single transaction can you track down a Bitcoin user? I have used this transaction to donate to Wikileaks. I have applied no special techniques to obsure my identity. How much information can find out about me on the blockchain. What tools would you use? Can you guess the following information? Can you prove it? How did I get the bitcoins I was donating? What was my total bitcoin balance at a given time? Please try not to violate other people's right to privacy. Knowing the Wikileaks donation address , one knows every addressthat contributed to them. Knowing a given address we are interested in, we can try tracing the coins back to when they were created (which can be harder if theywere mined by a large pool, in that case you'd probably get a lot oforigin blocks). Given an address we know when it received coins and from what address. If the particular wallet contained more than one receiving address, sometimes the addresses would be used together. If you have more than one address in the "From address", you know the person had to have them together in on wallet. And now a bit of knowledge one can gain from outside the Block Chain: A lot of people put notes like "My Bitcoin Address is: 1HWbVLhxj7bhewhyapMZpyhqWAeAhJd51E" in places like the forum. Then you can link the addresses to particular nicknames, and in some cases emails, names, facebook pages and so forth. If you use one address for everything, one can know if you contributed to Wikileaks, or other known addresses. If one would have a big node in the Bitcoin Network that by chance would be connected to your Client when it sends transactions using the known addresses, one could potentially trace the IP of your computer. If you have a static IP, this can identify you. So all in all, with enough resources, Continue reading >>
