Coinreport Dont Lose Your Bitcoin Wallet! Tips On How To Secure Your Bitcoins

Gotten yourself a couple of bitcoins and trying to find a way to keep them safe? Just like a regular wallet, you have to take precaution with your bitcoin wallet since you dont want to lose your money. It may seem a bit difficult to protect a virtual wallet, but if done properly you can definitely secure it. The following guide will explain a few practices you can do to keep your virtual coins safe and sound. Keep Only a Small Amount of Bitcoins in Your Wallet In having a wallet, whether a virtual or physical one, you wouldnt want to have all of your money in it since if you lose your wallet you are broke. Therefore, it is advised that you store only a few coins on your phone or computer which will be your everyday spending money. The rest should be kept secure at another location. This is a web-based wallet that stores your private bitcoin key online. This means your coins are controlled by someone other than you. In addition, it can place great power into the hands of the organization that runs your online wallet because they have the private key. On the other side, having a web based wallet is a good for when you want to have access to your bitcoins anywhere at any time. Here are a couple of known online wallet sites: Blockchain , Coinbase , Strongcoin . Out of these three, Strongcoin is the only one that allows you to encrypt your private keys before sending them online, offering a bit more security. A basic, yet imperfective way to protect your coins is to encrypt your wallet. Encrypting means setting a very strong (at least 16 letter) password with capital letters, punctuation marks, numbers, etc. This helps against most robbing mishaps, however there are limitations: Hackers could use a software to log your keystrokeshence even if you have a super strong passwor Continue reading >>

Top 5 Bitcoin Vanity Addresses

Top 5 Bitcoin Vanity Addresses

Throughout the course of Bitcoin history, there have been some rather unique addresses. Some users resort to vanity generation solutions, which allow anyone to create an address with specific letter combinationsthat matter to them. In 2017, this process has become more complicated, as it takes days, or even weeks, to generate a vanity address.Some have spent a long time searching for those addresses, while others luckily stumbled upon them. As most people are well aware of, some Bitcoin addresses are generated automatically yet seemingly contain a word that exists. Lightlord, a long-standing Bitcoin user, generated the worlds longest real-world prefix address known to date. Through a very thorough vanity generation process, he managed to find an address containing the word Embarassable . Even though the address contains upper and lower case letters, it is the longest word found in a single Bitcoin address so far. One thing that makes Bitcoin addresses so difficult to remember and type in manually is the mix of lowercase and uppercase letters. RyanC successfully generated a Bitcoin address which contains no uppercase letter whatsoever . Even though this address does not contain sequence of words whatsoever, it is well worth noting. Under the current circumstances, generating such a password would take up a lot of time and computational resources. Palindromes are quite intriguing in their own right, even though most people would never give them a second glance. The Bitcoin world has at least one palindrome address, which was generated by xhomerx10. To be more precise, it is an address that starts with 1234 and ends with 4321:. Having a Bitcoin address that begins with 1234 is rather unusual, to begin with, although not all of these wallet addresses are the product of van Continue reading >>

Bitcoin Addresses

Bitcoin Addresses

A bitcoin address is like your bank account number. A bitcoin address is what people use to send payments to you. Bitcoin addresses are 26-35 characters made up of letters and numbers, starting with a 1 or 3 (we'll explain the difference shortly). Bitcoin addresses slightly differ from bank account numbers, as you can actually create as many addresses as you like, all linked to your same bitcoin wallet. Bitcoin addresses are case sensitive, however not to worry if you do accidentally typo one character your wallet will not send the bitcoins, as the address will be invalid. As Bitcoin addresses are a little long and complex for most users to type out, QR codes are used to help make this part of the process more user friendly. a QR code is embedded with the bitcoin address and sometimes even an amount, which can then be scanned by mobile wallets. This will automatically complete the Bitcoin address for you, making it very quick and simple to send a payment. Multi-signature addresses are typically prefixed with a 3 instead of the original 1. A multi-signature is effectively just requiring 2 (or more) private keys to sign a transaction before it can be sent. This is more of an advanced feature of bitcoin, but is becoming more popular with a variety of wallets. Bitcoin vanity addresses are like having a personalised car registration plate You can choose the first part of the address. These are not often used, but can be quite a nice novelty idea.

Up Close With The New Multibit Hd Bitcoin Wallet

Up Close With The New Multibit Hd Bitcoin Wallet

Up Close With the New MultiBit HD Bitcoin Wallet May 23, 2014 at 18:50 UTC|UpdatedMay 23, 2014 at 18:51 UTC MultBit has been quietly dropping scraps of information about its new MultBit HD wallet for months now. At the recent Bitcoin2014 conference, Jim Burton and Gary Rowe of MultiBit gave CoinDesk a hands-on preview of the new software. One of the most popular wallets out there , MultiBit gets around 4,500 downloads every day. Since its launch in 2011, MultiBit has been downloaded 1.8 million times. That's a lot of users and a great deal of pressure when it comes to producing a product that will last. Rowe said: "We wanted [to build] software that could scale up to tens of millions of people." The new wallet is less of a redesign and more of a reimagination of their wallet; it has been totally rebuilt from the ground up. On the surface, the changes are obvious. In the current version of MultiBit known as MultiBit Classic in anticipation of the new wallet the technical aspects of bitcoin are clearly on show. Your address is shown in its raw form, for example. MultiBit HD hides all of that away behind a clean design that's heavy on accessibility. Large buttons make navigating the interface intuitive and it now includes a more refined contacts list, creating the sense that you're sending money to a person instead of a string of letters and numbers. "This is the kind of wallet you can give your mum," says Rowe. Under the hood, the software incorporates the standards that the most demanding bitcoin users would expect. MultiBit HD will be compatible with the Trezor hardware wallet and the HD label refers to the fact that it will be a " hierarchical deterministic "wallet, meaning that you will be able to regain access to addresses created by MultiBit HD with a single 'seed' Continue reading >>

Yet Another Cool Checksum Address Encoding #55

Yet Another Cool Checksum Address Encoding #55

My preference is that a checksum-enabled Ethereum address is immediately recognizable as such. The proposed solution is not immediately recognizable as being distinct from a standard Ethereum address and could be confused for being a strangely-cased version of non-checksummed addresses. Although it offers superior backwards compatibility, I believe will only cause additional confusion to the end-user. Since the change in format serves to make the address less error prone through checksums, I posit they should also be immediately recognizable through a fixed prefix or otherwise obvious identifier. One reason why I prefer ICAP over this proposed solution is that it signals to the user clearly that this is an Ethereum address and cannot be confused with a transaction/block hash. I disagree @tgerring that it will cause confusion: to a layman, it will be indistinguishable from a normal address. This approach is very easy to implement in the client side and doesnt require much. I would say this could be adopted as a great intermediary before ICAP also would be a good alternative if ICAPs don't catch on. I did a rudimentary implementation on javascript in the web3 object: var isAddress = function (address) { if (!/^(0x)?[0-9a-f]{40}$/i.test(address)) { // check if it has the basic requirements of an address return false; } else if (/^(0x)?[0-9a-f]{40}$/.test(address) || /^(0x)?[0-9A-F]{40}$/.test(address)) { // If it's all small caps or all all caps, return true return true; } else { // Otherwise check each case address = address.replace('0x',''); // creates the case map using the binary form of the hash of the address var caseMap = parseInt(web3.sha3('0x'+address.toLowerCase()),16).toString(2).substring(0, 40); for (var i = 0; i < 40; i++ ) { // the nth letter should be uppe Continue reading >>

Question (don't Upvote): Are Bitcoin Addresses Case Sensitive? I See Both Upper And Lower Case, But Are They Interchangeable? : Bitcoin

Do not use URL shortening services: always submit the real link. Begging/asking for bitcoins is absolutely not allowed, no matter how badly you need the bitcoins. Only requests for donations to large, recognized charities are allowed, and only if there is good reason to believe that the person accepting bitcoins on behalf of the charity is trustworthy. News articles that do not contain the word "Bitcoin" are usually off-topic. This subreddit is not about general financial news. Submissions that are mostly about some other cryptocurrency belong elsewhere. For example, /r/CryptoCurrency is a good place to discuss all cryptocurrencies. Promotion of client software which attempts to alter the Bitcoin protocol without overwhelming consensus is not permitted. Trades should usually not be advertised here. For example, submissions like "Buying 100 BTC" or "Selling my computer for bitcoins" do not belong here. /r/Bitcoin is primarily for news and discussion. Please avoid repetition /r/bitcoin is a subreddit devoted to new information and discussion about Bitcoin and its ecosystem. New merchants are welcome to announce their services for Bitcoin, but after those have been announced they are no longer news and should not be re-posted. Aside from new merchant announcements, those interested in advertising to our audience should consider Reddit's self-serve advertising system . Do not post your Bitcoin address unless someone explicitly asks you to. Be aware that Twitter, etc. is full of impersonation. Continue reading >>

Understanding Bitcoin Addresses And Private Keys.

Understanding Bitcoin Addresses And Private Keys.

Understanding Bitcoin addresses and private keys. I have recently thought about bitcoin addresses and the private keys, and just cant get my head around how they are created and link together, would love if someone could break it down into laymans term. My understanding of it is that a long string of ?? is passed through sha256 and creates an address (bitcoin address). from the address you can not go backwards and find the original string of ? but if you have the private key which in some way is related to the string ? then you can access the address and the bitcoin stored there. . I am probably way off but sure thats why i'm here, to learn There's a good video somewhere. Sorry can't remember what it was called.

Smtp - Are Email Addresses Case Sensitive? - Stack Overflow

Smtp - Are Email Addresses Case Sensitive? - Stack Overflow

I've read that by standard first part of e-mail is case sensitive, however I've tried to send e-mail to [email protected], [email protected] and [email protected] - it has arrived in each case. How do mail servers handles usernames? Is it possible to miss with case and that message wouldn't be delivered? Is it really very important to use exactly same letter case, as was written while registering when giving your e-mail address? The standard mailbox naming convention is defined to be "[email protected]"; contemporary usage permits a much broader set of applications than simple "user names". Consequently, and due to a long history of problems when intermediate hosts have attempted to optimize transport by modifying them, the local-part MUST be interpreted and assigned semantics only by the host specified in the domain part of the address. So yes, the part before the "@" could be case-sensitive, since it is entirely under the control of the host system. In practice though, no widely used mail systems distinguish different addresses based on case. The part after the @ sign however is the domain and according to RFC 1035, section 3.1, "Name servers and resolvers must compare [domains] in a case-insensitive manner" In short, you are safe to treat email addresses as case-insensitive. 'In short, you are safe to treat email addresses as case-insensitive.' I'd phrase it stronger: "you're unsafe to treat email-addresses as case-sensitive manner" Especially when checking for duplicates in user-databases, etc. Geert-Jan Nov 16 '13 at 23:00 I'd disagree with the conclusion. If you're looking for duplicates in a database - yes, a case insensitive match is probably the best way to go, but I've seen code where the email address is converted to lower case prior to sending. That's not a go Continue reading >>

Why Bitcoin Matters - The New York Times

Why Bitcoin Matters - The New York Times

Marc Andreessen, a co-founder of the venture capital firm Andreessen Horowitz.Credit Keith Bedford/Reuters Editors note: Marc Andreessens venture capital firm, Andreessen Horowitz, has invested just under $50 million in Bitcoin-related start-ups. The firm is actively searching for more Bitcoin-based investment opportunities. He does not personally own more than a de minimis amount of Bitcoin. A mysterious new technology emerges, seemingly out of nowhere, but actually the result of two decades of intense research and development by nearly anonymous researchers. Political idealists project visions of liberation and revolution onto it; establishment elites heap contempt and scorn on it. On the other hand, technologists nerds are transfixed by it. They see within it enormous potential and spend their nights and weekends tinkering with it. While regulators debate the pros and cons of bitcoins, this volatile digital currency inspires the question: What makes money, money? By Channon Hodge, David Gillen, Kimberly Moy and Aaron Byrd on Publish Date November 24, 2013. Eventually mainstream products, companies and industries emerge to commercialize it; its effects become profound; and later, many people wonder why its powerful promise wasnt more obvious from the start. What technology am I talking about? Personal computers in 1975, the Internet in 1993, and I believe Bitcoin in 2014. One can hardly accuse Bitcoin of being an uncovered topic, yet the gulf between what the press and many regular people believe Bitcoin is, and what a growing critical mass of technologists believe Bitcoin is, remains enormous. In this post, I will explain why Bitcoin has so many Silicon Valley programmers and entrepreneurs all lathered up, and what I think Bitcoins future potential is. First, Bitcoi Continue reading >>

What Are Addresses On Blockchains? Blockchain Address 101

What Are Addresses On Blockchains? Blockchain Address 101

Blockchain Address 101. Blockchain Addresses are an important concept in cryptocurrencies and blockchains . In our guide, we explain. What addresses are, how they are created and what the differences between different kind of addresses on different blockchains are. What Are Addresses on Blockchains? Blockchain Address 101 In the early days of Bitcoin , it was possible to send payments to an IP-address like 104.25.248.32 (which is blockgeeks.com). This was planned to be a convenient method to use Bitcoins without dealing with unhandy public keys and addresses. However, after the Bitcoin developers realized that this way of sending coins could be subject to serious man- in-the-middle-attacks, the option was disabled and did never come back. This anecdote of Bitcoins early days seems to have mostly historic values. But it demonstrates what an address is: It is not something special or something set in stone. It is just a placeholder to accept and send blockchain transactions. Like an IBAN or SWIFT address. The address itself doesnt matter, nor does its format. The only thing matters are that the address serves its purpose to enable payments to an entity which has a unique information. Usually, a private key, to exclusively access the funds. The address is nothing but a secure identifier. However, while SWIFT or IBAN numbers are assigned by central authorities like banks, blockchain addresses exist. Every blockchain address possible already existed, long before a wallet found it. The reason is that blockchain addresses are the result of a mathematical operation. The Public Key: Where the Blockchain Address Generation begins After Pay to IP had been abandoned in Bitcoin , P2PKH became the new standard format for Bitcoin addresses. You might know it; it looks like this: A st Continue reading >>

Drawing The Distinction Between The Uppercase B And Lowercase B In Bitcoin

Drawing The Distinction Between The Uppercase B And Lowercase B In Bitcoin

Share your email with us to receive updates on Blockchain and the industry. A commonarea of confusionwhen talking about Bitcoin is the use of the uppercase B versus the lowercase b. What is the difference, and when do you use each one? In this post, we take a few minutes to explain what each of them represent, and how to use them. Bitcoin (the protocol and payment network) Bitcoin with a capital B is typically associated with Bitcoin the protocol and payment network. The uppercase form, Bitcoin, is also often used to refer to as the ecosystem as a whole. Using Bitcoin with a capital B is the common way of referencing Bitcoin when writing about it in general terms. An example would be, I just learned about Bitcoin, and its a fast and cheap way for merchants to accept payments. Bitcoin with a lowercase b written as bitcoin is usually associated specifically with bitcoin as the currency. When you intend to referencehow much of the currencywas transacted, or youre focusing solely on the currency and not the broader payment network or protocol as a whole, you can use the lowercase form, bitcoin. An example would be, I just sent two bitcoins from my Blockchain Wallet to the merchant. These are not hard and fast rules, but they can helpful when trying to avoid confusion. Whichever way you decide to write Bitcoin, making sure you provide adequate context is usually all you need to ensure youre explaining yourself clearly. It becomes particularly significantto draw the distinction when writing about the technical aspects of Bitcoin, and when explaining the differences between the protocol and the currency like we did here.

Bitcoin Addresses - Dummies

Bitcoin Addresses - Dummies

Similar to the way e-mail addresses work, a bitcoin address can be used to both send and receive data or in this case, bitcoins. That said, there is one major distinction to be made between bitcoin addresses and e-mail addresses. People can have multiple bitcoin addresses they can use to send and receive transactions. In fact, it is advisable to use a brand new bitcoin address for every transaction, which may or may not be manageable for individual users depending on how many transactions they intend to process on a daily basis. Contrary to popular belief, the generation of a new bitcoin address does not require an active Internet connection. A bitcoin address is an identifier representing a possible destination or origin for a bitcoin transaction. Every bitcoin address is between 26 and 35 alphanumeric characters in length and can start with a 1 or a 3. Creating new or additional bitcoin addresses can be done free of charge through the installed bitcoin software, or you can obtain a bitcoin wallet address from an exchange or online wallet provider. One important aspect of a bitcoin address to keep in mind is that every address is case sensitive and exact. A bitcoin address like the following has both uppercase and lowercase letters in its string of characters: Changing an uppercase letter to a lowercase letter or vice versa would result in an invalid recipient address, and the funds would not be transferred. There is always an off chance of an invalid address being accepted as a recipient, but that only occurs once every 4.29 billion transactions. Use a different bitcoin address for every transaction. Keep in mind that there is technically nothing wrong with using the same address over and over again, but using a new address for every transaction creates an additional Continue reading >>
