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 >>

Protocol Documentation

Protocol Documentation

This page describes the behavior of the reference client . The Bitcoin protocol is specified by the behavior of the reference client, not by this page. In particular, while this page is quite complete in describing the network protocol, it does not attempt to list all of the rules for block or transaction validity. Type names used in this documentation are from the C99 standard. For protocol used in mining, see getblocktemplate . Usually, when a hash is computed within bitcoin, it is computed twice. Most of the time SHA-256 hashes are used, however RIPEMD-160 is also used when a shorter hash is desirable (for example when creating a bitcoin address). Example of double-SHA-256 encoding of string "hello": hello2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824 (first round of sha-256)9595c9df90075148eb06860365df33584b75bff782a510c6cd4883a419833d50 (second round of sha-256) For bitcoin addresses (RIPEMD-160) this would give: hello2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824 (first round is sha-256)b6a9c8c230722b7c748331a8b450f05566dc7d0f (with ripemd-160) Merkle trees are binary trees of hashes. Merkle trees in bitcoin use a double SHA-256, the SHA-256 hash of the SHA-256 hash of something. If, when forming a row in the tree (other than the root of the tree), it would have an odd number of elements, the final double-hash is duplicated to ensure that the row has an even number of hashes. First form the bottom row of the tree with the ordered double-SHA-256 hashes of the byte streams of the transactions in the block. Then the row above it consists of half that number of hashes. Each entry is the double-SHA-256 of the 64-byte concatenation of the corresponding two hashes below it in the tree. This procedure repeats recursively until we reach Continue reading >>

Facebook Is Banning All Ads Promoting Cryptocurrencies Including Bitcoin And Icos

Facebook Is Banning All Ads Promoting Cryptocurrencies Including Bitcoin And Icos

Facebook is banning all ads promoting cryptocurrencies including bitcoin and ICOs Its an intentionally broad policy aimed at stopping scammers. GEOFFROY VAN DER HASSELT/AFP/Getty Images Facebook is banning all ads that promote cryptocurrencies, including bitcoin, in an effort to prevent people from advertising what the company is calling financial products and services frequently associated with misleading or deceptive promotional practices. That means no advertiser even those that operate legal, legitimate businesses will be able to promote things like bitcoin and other cryptocurrencies, initial coin offerings ICOs for short or binary options, according to a Facebook blog post. A James Altucher crypto ad, delivered by Facebooks Audience Network That also means that crypto-genius James Altucher , whose ads have appeared all over the internet and have become a meme of sorts for the entire crypto industry, wont be able to advertise on Facebook. Ads that violate the companys new policy will be banned on Facebooks core app, but also in other places where Facebook sells ads, including Instagram and its ad network, Audience Network, which places ads on third-party apps. This policy is intentionally broad while we work to better detect deceptive and misleading advertising practices, wrote Rob Leathern, one of Facebooks ad tech directors. We will revisit this policy and how we enforce it as our signals improve. The cryptocurrency boom/bubble has led to scams and wild price fluctuations that have cost a lot of people including unsophisticated investors a lot of money. Scams are illegal, but gambling on investments you dont understand is not. Look for blowback from entrepreneurs and investors who argue that the move unfairly punishes legitimate cryptocurrency companies and relat Continue reading >>

What Is The Difference Between

What Is The Difference Between "bitcoin Wallet Id" And "bitcoin Wallet Address"?

A Bitcoin address is a single-use token. 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. Example: 1B2S4Nf8jD3fshHodzuYhframoQsQaZEcZ A Wallet ID (also called your Wallet Identifier) acts similarly to a username you'd use to access your email, or log into Facebook. To log into your wallet, you'd use your Wallet ID, password, plus any form of Two Factor Authentication you've enabled. It looks like a string of letters and numbers, like the sample Wallet ID below: A Wallet ID is only used for the login process, and it's different from a bitcoin address. In other words, it can't be used to send or receive funds. For security reasons, we strongly recommend you don't share your Wallet ID publicly, or with anyone. 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 >>

Facebook Bans Ads For Bitcoin And Other Cryptocurrencies

Facebook Bans Ads For Bitcoin And Other Cryptocurrencies

Technology |Facebook Bans Ads for Bitcoin and Other Cryptocurrencies Although Facebooks chief executive, Mark Zuckerberg, has expressed an interest in digital currencies, the company said ads for them were frequently associated with misleading or deceptive promotional practices. Credit Jeff Roberson/Associated Press SAN FRANCISCO Want to get rich quick through Bitcoins or other virtual currencies? Youll have to do it without Facebook. The social network said Tuesday that it would ban all ads for Bitcoin and other cryptocurrencies, in order to stop promotions that it sees as frequently associated with misleading or deceptive promotional practices. Under Facebooks new policy, no ads from well-known digital currency exchanges or for initial coin offerings will be allowed. Among those who will be affected is James Altucher , a self-described crypto genius whose viral ads have become a talking point in how the cryptocurrency boom has led to scams and wild price fluctuations. Facebooks move followed questions about whether it has done enough to protect its site from bad actors. The company has been trying to clamp down on misinformation and false news after admitting last year that Russian agents had used it to spread divisive and polarizing messages. The world of cryptocurrencies, which people have flooded into as prices soared in recent months, has also increasingly raised fears that parts of the market are dogged by scams. The Securities and Exchange Commission said Tuesday that it had halted what may have been a fraudulent initial coin offering that asked people to fund what was supposed to be the worlds first decentralized bank. Rob Leathern, a Facebook product management director, announced the ban on cryptocurrency ads in a blog post . He said the ban was intentionall Continue reading >>

Bitcoin's Price Bubble Will Burst Under Government Pressure

Bitcoin's Price Bubble Will Burst Under Government Pressure

Bitcoin's price bubble will burst under government pressure The cryptocurrency is up 1,600% in two years but state efforts to remove its near-anonymity will undermine its popularity Bitcoins price is up 600% over the past 12 monthsPhotograph: Alexander Demianchuk/TASS The cryptocurrency is up 1,600% in two years but state efforts to remove its near-anonymity will undermine its popularity First published on Monday 9 October 2017 07.51EDT Is the cryptocurrency bitcoin the biggest bubble in the world today, or a great investment bet on the cutting edge of new-age financial technology? My best guess is that in the long run, the technology will thrive, but that the price of bitcoin will collapse. If you havent been following the bitcoin story, its price is up 600% over the past 12 months, and 1,600% in the past 24 months . At over $4,200 (as of 5 October), a single unit of the virtual currency is now worth more than three times an ounce of gold. Some bitcoin evangelists see it going far higher in the next few years. What happens from here will depend a lot on how governments react. Will they tolerate anonymous payment systems that facilitate tax evasion and crime? Will they create digital currencies of their own? Another key question is how successfully bitcoins numerous alt-coin competitors can penetrate the market. Warnings grow louder over cryptocurrency as valuations soar In principle, it is supremely easy to clone or improve on bitcoins technology. What is not so easy is to duplicate bitcoins established lead in credibility and the large ecosystem of applications that have built up around it. For now, the regulatory environment remains a free-for-all. Chinas government, concerned about the use of bitcoin in capital flight and tax evasion, has recently banned bitcoin ex Continue reading >>

There's A Facebook Alternative, It's Called Self-sovereign Identity

There's A Facebook Alternative, It's Called Self-sovereign Identity

There's A Facebook Alternative, It's Called Self-Sovereign Identity Apr 6, 2018 at 02:01 UTC |UpdatedApr 6, 2018 at 10:37 UTC Kaliya " Identity Woman " Young is a co-founder of the Internet Identity Workshop and of HumanFirst.Tech and an independent expert on blockchain and identity systems who consults with governments, companies and startups. This article was inspired by conversations with Tony Fish and Lubna Dajani. Following the Cambridge Analytics election scandal, the meme #DeleteFacebook is widely circulating, leading to the next question, "what is the alternative?" The answer isn't a "new, better" platform - it's an open standards-based infrastructure that centers on people and enables a whole new ecosystem to flourish. Self-sovereign identity puts people in charge their own digital identities. It means that individuals have choice and sovereignty over their digital selves to the same degree we have control over our physical selves. This aligns with the fact that we all have inherent dignity that does not come from being born in a certain place or with certain attributes other than being human. With self-sovereign identity, individuals don't rely on another party, such as Facebook, to issue them an identifier for their use. They create the identifiers and own and control them along with what information is shared with whom under what conditions. Under the status quo, where we don't own and control our own identifiers, we are subject to the the terms of another party, whether this is a corporation (Google, Facebook, LinkedIn, Twitter etc) or a government. These actors have a role to play in the identity ecosystem, but the new self-sovereign identity tools will shift the power balance. The large organizations will be in service to, and in a relationship with, the Continue reading >>

Address - What Is Bitcoin Id? - Bitcoin Stack Exchange

Address - What Is Bitcoin Id? - Bitcoin Stack Exchange

The paragraph you copied from the Bitcoin wiki is imprecise. Transactions result in transaction outputs that usually are associated with specific addresses . I.e. there is a balance of bitcoins associated with an address, that only can be spent by an order signed with the address' corresponding private key. The bitcoins itself are not identifiable, rather the path that they arrived through may be traceable. As an example, let's assume there are two transactions: Transaction 1: A --- 1 BTC ---> BTransaction 2: B --- 1 BTC ---> CA, B, and C are addresses in this case. What the text from the wiki is trying to confer is that if somebody knew who owned address A, they might be able to force this person to tell them who owns the address B. This second Bitcoin user might then be forced to reveal the owner of address C. However, the bitcoins itself do not have any identifiable footprint in the system, they merely exist in form of a transaction output's balance that may only be created through mining or the destruction of a previous balance. You can see addresses and transactions. But you can't get the owner of this address unless he or someone else is publishing the identity. For example, this happend when the coins of silk road where seized: 1F1tAaz5x1HUXrCNLbtMDqcw6o5GNn4xqX .Everyone can check where those coins went to from there on. Blockchain.info allows people to add a note to an address, to let others easily find those addresses. Normaly people would not post their identity. So if you look into the blockchain and see someone send 1 BTC to someone else, you will never know which persons traded those coins. Therefore it's anonymous. Continue reading >>

What's A Bitcoin Address? Public Keys, Private Keys, And Addresses Explained

What's A Bitcoin Address? Public Keys, Private Keys, And Addresses Explained

One of the things I get asked all the time is what is a bitcoin address?. Theres the full technical answer for someone who wants to build bitcoin technologies, but theres a lot less to know to bea user of bitcoin nowadays. For example, I bet you didnt know that email runs on a protocol called SMTP (Simple Mail Transfer Protocol) which plays a similar role in email that the bitcoin protocol does in transferring bitcoin (although with some key differences). But if I asked you to fire off an email to [email protected] you could have something ready to send in less than a minute. Sending bitcoin is a similar level of complexity, only you dont need to write a message to send bitcoin. Even Fluffy can send an email with her eyes closed. A lot of people seem to worry about learning the complex mathematics behind the bitcoin protocol before buying and using bitcoin. This might have been true pre-2014 before hoards of startups set out to make bitcoin accessible, but today its simply not the case. So Im going to give you the basic information you need to know to be a userof bitcoin, but not a mathematical expert. So lets get started! A bitcoin address is one of the key concepts that make the currency and the blockchain work. It isnt quite as straightforward to define or explain as an email address. You first need to know about two other parts of bitcoin in order to see how the address fits into the picture: a private key and a public key. The main difference is that you dont use the same address to send bitcoin as you do to receive it. Instead, there are three key terms to know: Private key : a 64 character long code using any combination of the letters A-F and the numbers 1-9. You can see an example of a private key on the image above.This is what you use to send money out of you Continue reading >>

How To Mine Bitcoins

How To Mine Bitcoins

Twitter Pushes Android App Update To Fix The Me Tab Bug Mining bitcoins a process that helps manage bitcoin transactions as well as create new wealth is the new Beanie Babies. Luckily for us, however, bitcoins seem to be going up in value and should maintain their value over time, unlike your mint condition Tiny the stuffed Chihuahua. But how do you get bitcoins? You can begin by buying them outright, but the market is currently wild. At $188 per coin, the direction of the bitcoin is anyones guess right now and, unlike equities, these things dont split. In short, you should probably mine. But what is bitcoin mining? Think of it as work done by groups of people to find large prime numbers or trying keys to decrypt a file. You can read a lot more about it here but just understand that for every block mined you get 25 coins or, at current rates, $4,722.25. Currently a single bitcoin is valued at $188, an alarming result that is probably caused by money movements related to Cyprus and a general bubble-like excitement over the platform in general. In fact, many wager that the DDOS attacks on many bitcoin-related services are direct action by hackers to inject instability in order to reduce the price. As it stands, mining solo is very nearly deprecated. The process of finding blocks is now so popular and the difficulty of finding a block so high that it could take over three years to generate any coins. While you could simply set a machine aside and have it run the algorithms endlessly, the energy cost and equipment deprecation will eventually cost more than the actual bitcoins are worth. Pooled mining, however, is far more lucrative. Using a service like Slushs pool (more on that later) you can split the work among a ground of people. Using this equation: (25 BTC + block fe Continue reading >>
