How to Verify a Bitcoin address generated by Bitaddress.org
The Crypto Dad goes through the steps involved in verifying the webpage at https://bitaddress.org Bitaddress.org is a website that allows you to generate a unique bitcoin address that you can use for a cold-storage paper wallet. Verification of this site is very important. The steps followed are outlined here: 1. Save the developer’s signing file on your computer. 2. Import the signing file into your GPG keyring 3. Save the CHANGELOG to your computer 4. Verify the signed CHANGELOG using GPG and the signing key you downloaded in step 1 5. Save the wallet page to your computer as HTML only. 6. Generate a SHA256 hash from the saved webpage 7. Verify that the generated SHA256 hash matches the hash in the now-trusted CHANGELOG You can get the GnuPG verification software at: https://gnupg.org/ Specifically Gpg4Win. https://www.gpg4win.org/index.html Sha Sum Checking is done with: MD5 & SHA Checksum Utility https://raylin.wordpress.com/downloads/md5-sha-1-checksum-utility/ Or The online Checker http://onlinemd5.com/ Donate Bitcoin: 1JBxwXG8P6PYKKsrHKzQduM8s8RoV3dnjr

Blockchain tutorial 17: Generate Bitcoin address
This is part 17 of the Blockchain tutorial explaining how to generate a Bitcoin address using an online tool. In this video series different topics will be explained which will help you to understand blockchain. Bitcoin released as open source software in 2009 is a cryptocurrency invented by Satoshi Nakamoto (unidentified person or group of persons). After the introduction of Bitcoin many Bitcoin alternatives were created. These alternate cryptocurrencies are called Altcoins (Litecoin, Dodgecoin etc). Bitcoin's underlying technology is called Blockchain. The Blockchain is a distributed decentralized incorruptible database (ledger) that records blocks of digital information. Each block contains a timestamp and a link to a previous block. Soon people realises that there many other use cases where the Blockchain technology can be applied and not just as a cryptocurrency application. New Blockchain platforms were created based on the Blockchain technology, one of which is called Ethereum. Ethereum focuses on running programming code, called smart contracts, on any decentralized application. Using the new Blockchain platforms, Blockchain technology can be used in supply chain management, healthcare, real estate, identity management, voting, internet of things, etcetera, just to name a few. Today there is a growing interest in Blockchain not only in the financial sector but also in other sectors. Explaining how Blockchain works is not easy and for many the Blockchain technology remains an elusive concept. This video series tries to explain Blockchain to a large audience but from the bottom up. Keywords often used in Blockchain conversation will be explained. Each Blockchain video is short and to the point. It is recommended to watch each video sequentially as I may refer to certain Blockchain topics explained earlier.

What is a Bitcoin Address?
http://www.bitcoinreport.info - What is a Bitcoin Address? While a Bitcoin address works in a similar way to a bank account number, it is much more than that. The best way to answer the question "what is a Bitcoin address?" is to define it as a Bitcoin wallet identifier, of which there can be many. Unlike a bank account number, a Bitcoin wallet can generate an unlimited number of Bitcoin addresses, which can be used to identify incoming funds from regular payers, or even as a way of enhancing your privacy. Obviously to have a Bitcoin address you first need a Bitcoin wallet, and if you check my videos here you will see that I have put up one on the subject of choosing such a wallet. https://www.youtube.com/watch?v=lUZQ7RxR3rU

How transactions are verified in Bitcoin Blockchain - Longest chain rule explained
How transactions are verified in Bitcoin Blockchain - Longest chain rule explained Watch our earlier Blockchain videos Blockchain Simplified: https://www.youtube.com/watch?v=LWAYveDotb0&t=1s Blockchain Technology explained: https://www.youtube.com/watch?v=gVLIentRlIk&t=1s Have you wondered how transaction get approved in a Bitcoin block chain? Why you need to wait for 3 to 6 confirmations for the transactions to appear in your wallet. This video attempts to explain how a Bitcoin transaction is approved and the process behind it. Let’s assume Mr. Gobish transferred Bitcoin worth 100$ from one crypto exchange to another. Once he does the transfer, the transaction message is sent to the network and passed around all the network participants which are also called nodes. This is added to the transaction pool. Currently, the transaction is in an ‘unconfirmed’ state. All the transactions in the transaction pool will be in an unconfirmed status. Now we will understand who is a miner. In simple words, those who validate new transactions and record them on the global ledger of Blockchain are called miners and this activity is called mining. To make it simple, let’s assume there are currently 3 miners who are trying to confirm the transactions from transaction pool including Gobish’s transaction of $ 100. Normally miners will select those transactions which will generate a higher transaction fees for them. Currently, the numbers of confirmed blocks in the Blockchain public ledger is 998. Once the miners identify that the 998th block is a valid block they will try to create a candidate block by adding unconfirmed transactions from the transaction pool. Now these miners are trying to add the 999th block. To add the blocks they have to solve a complex mathematical problem. This is known as Proof of Work (POW). Let’s assume all the 3 miners were able to solve this problem and have Proof of Work. Now we have 3 different candidate blocks, let’s call them 999 A, 999B and 999C Now which of these block will form part of the valid block will depend upon the longest chain rule. Let’s understand what is longest chain rule is. Now there are other miners who are trying to create other valid blocks and based upon the speed by which a block is created others miners will keep on adding their blocks on top of the earlier blocks. Here in this case Minor C had a better processor which was able to create a block faster than the miner A and B and hence new blocks were created on top of the block 999C. Now the longest chain is the one created by 999C and it will be keep on adding other blocks like 1000, 1001 and so on as miner C solved the proof of work before miner A and B. So what happens to the blocks 999A and 999B? They have to create the Proof of Work again with new set of transactions from the transaction base. Each confirmations represent adding each block. Each confirmation will take on an average of around 10 minutes or more per block. Applying the longest chain rule and proof of work, unconfirmed transaction will become a confirmed transaction and added to the Blockchain ledger Once the blocks are added miner will receive a transactions fees and block fees which will be the new Bitcoin created as an incentive for approving the transactions. Block rewards will be reducing every year and in the end only transaction fees will be there as new Bitcoins will not be created. We will get in to more details about mining and the incentives in our subsequent video.

Blockchain tutorial 28: Bitcoin Improvement Proposal 39 (BIP-39) mnemonic words
This is part 28 of the Blockchain tutorial. In this video series different topics will be explained which will help you to understand blockchain. It is recommended to watch each video sequentially as I may refer to certain Blockchain topics explained earlier. WHAT IS A WALLET -------------------------------- A wallet stores private keys. The word wallet is misleading, it just stores private keys and not the coins. The public addresses are automatically derived from the private keys. If you open your Bitcoin wallet and one of your Bitcoin addresses shows that is has a balance of 5 BTC, than these bitcoins are not actually stored in your wallet. It means that these 5 bitcoins were transferred to your Bitcoin address during a transaction. This transaction (TX) information is stored on the blockchain. Your wallet queries the blockchain and searches for Unspent TX Outputs (UTXO) for all your Bitcoin addresses to display their balances. The bitcoins on these UTXO can be unlocked and transferred to another Bitcoin address using the private keys stored in the wallet. NON-DETERMINISTIC WALLET ------------------------------------------------- Wallets stores private keys but they also create these private keys. The private keys are randomly generated numbers which are not related to each other. You can not derive these private keys with an algorithm. Hence the words "non-deterministic". If you use a non-deterministic wallet you must make regular backups of these private keys. If you have problems with your wallet, you can restore your wallet by importing the backupped private keys. Explaining a non-deterministic wallet (for educational purpose only), see: https://www.mobilefish.com/services/cryptocurrency/cryptocurrency.html DETERMINISTIC WALLET ----------------------------------------- A deterministic wallet uses 12 - 24 words to create a 512 bit seed. These words are called mnemonic words, because they are more easily to remember than this long hexadecimal string. The 512 bit seed is used to create a master private key. This master private key in turn is used to create private keys and corresponding public addresses. Generally speaking using these 12 - 24 words will complete restore your wallet with exactly the same private keys and corresponding public addresses. Hence the word "deterministic". It is imperative that you safely store these 12 - 24 words, without it you have no access to your private keys. To see how an Ethereum deterministic wallet works, see YouTube movie: https://youtu.be/cqz8-hOz_nk BIP-39 ----------- The acronym BIP means Bitcoin Improvement Proposal. BIPs are design documents for introducing features or information to Bitcoin. An overview can be found at: https://github.com/bitcoin/bips BIP-39 describes the implementation of mnemonic words for the generation of deterministic wallets, see: https://github.com/bitcoin/bips/blob/master/bip-0039.mediawiki BIP-39 is becoming an industry standard which is not only used for Bitcoin wallets but it is also used in Ethereum, Dash and other Altcoin wallets. The wordlist can be found at: https://github.com/bitcoin/bips/blob/master/bip-0039/bip-0039-wordlists.md For additional security you can allow users to enter a passphrase. Use the Password-Based Key Derivation Function 2 (PBKDF2) together with the mnemonic phrase and salt to produce a 512 bits seed. If an attacker gets its hands on your mnemonic words the passphrase (it you have set it) will prevent the attacker to access the private keys. PBKDF2 is purposefully made slow to make brute force dictionary attack very difficult. The 512 bit seed is used to generate deterministic wallets. How to generate deterministic wallets is explained in BIP-32 and BIP-44. It is important to know that each time you enter a different passphrase it will generate a valid 512 bit seed and thus a valid wallet with valid public and private key pairs. This feature can help you limit your loss after a 5$ wrench attack. You can setup a second deterministic wallet with some coins to satisfy the attacker. If you do not know what a 5$ wrench attack is watch this comic: https://xkcd.com/538/ Storing your passphrase at the same location as your mnemonic words is not recommended and beats the purpose. But if you lose your passphrase, you have lost access to your coins. A JavaScript implementation of BIP-39 can be found at: https://github.com/bitcoinjs/bip39 How this JavaScript library is used see: https://www.mobilefish.com/download/ethereum/bip39.html A Mnemonic Code Converter web application can be found at: https://iancoleman.github.io/bip39 Check out all my other Blockchain tutorial videos https://goo.gl/aMTFHU Subscribe to my YouTube channel https://goo.gl/61NFzK The presentation used in this video tutorial can be found at: https://www.mobilefish.com/developer/blockchain/blockchain_quickguide_tutorial.html #mobilefish #blockchain #bitcoin #cryptocurrency #ethereum

How Bylls uses PGP to generate secure Bitcoin payment invoices (alternative to Bitpay's BIP70)
Bylls.com proposes a PGP-based invoicing protocol using Keybase. Designed by Francis Pouliot and implemented by Arthur Gerbelot and Paul Laffeuillade using OPENPGPJS. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 The following is a demo of Bylls.com - a Bitcoin payments and exchange applicaiton which lets canadians pay bills and send money to anyone in Canada with Bitcoin. To find out more check out Bylls.com ! To show that this is really me I have signed the URL with my PGP key: https://www.youtube.com/watch?v=GPGx7WPxbbY&feature=youtu.be Verify it at keybase.io/verify -----BEGIN PGP SIGNATURE----- Version: Keybase OpenPGP v2.0.76 Comment: https://keybase.io/crypto wsBcBAABCgAGBQJaUm3gAAoJEOppJT/UFvt7rz4H/Rkpu57dfGvjDlwmcw88txJI ZHE14Ot/ngNZbv7LjEEkYKSAwt0M6lvXaIUlJQ7u7nosPXfI0q2nJWgEhKM/l3Rk KJm6KO4NZUtq0Kkn0LVcw7GOt/k9W9jYutshPBGvFWVTbzmES/+R6Pu58OT1OaCW XZTb/fKLMiMDqj3wHODnSyjGxocM6j1Ifh0Ame5Skq8OoJAmesEl8Y5uYKseoxzi Mknx1xOGlYhUhPFeoprYDl6xj5Tnl9AC82c0dQ/XSvJWWbGeXXQhvJpD4G9B5qMz 8GMvSAw7al+YzJxt+hdAaHZ3orWNjOx2pPAttDM3abJ3Ihu33SELybOdJNxbdl4= =dmpp -----END PGP SIGNATURE----- HOW TO USE THE PGP SIGNED INVOICE "CRYPTO CONTRACT" IN BYLLS.COM PGP instructions The following is a summary of your Bylls transaction invoice which has been cryptographically signed by Bylls, using the Bylls PGP key in accordance to the OpenPGP standard. It is your responsibility to verify that the contents of this signed invoice are accurate, and that the signature is valid. It is a cryptographic contract between you and Satoshi Portal Inc. To validate the signed invoice, copy and paste it here - the signature will be verified and must be signed by Bylls. You can use any PGP software to very the signature - our PGP key is hosted here What is this? This signed invoice consists of irrefutable evidence of Bylls' promise to send an agreed-upon amount of Canadian dollars to the specific bill or bank account of your biller or personal payee, in exchange for an agreed-upon amount of Bitcoin sent to the address specified in the invoice within a timeframe of 15 minutes. You can use this signed invoice as evidence in case dispute mediation is required. This signed invoice is a contract between you, the Bylls user, and Satoshi Portal Inc., the company which operates Bylls.com. This document is the official invoice, and its content is that be the only considered as valid. If there is a discrepancy between this signed invoice and any other invoice, this signed invoice is the one considered official and valid. The three benefits of this are: Authentification: this proves that the invoice was created by Bylls, and not another entity usurping the Bylls identity. This protects you from "phishing" attempts and fake scam imitations of Bylls. Integrity: this proves that the content of the invoice has not changed since it was presented to you in your web browser - any change will make the signature invalid. For example, this protects you from hackers trying to change the Bylls Bitcoin address in the invoice to their own address. Non-repudiation: Bylls cannot deny having create this invoice, since it could only have been signed by our PGP key. In addition, since the Bitcoin address and the requested Bitcoin amount are specified in the signed invoice, any third party can validated the signature and audit the blockchain to see whether or not the requested amount of bitcoins were in fact received, and also check if they were received during the requested timeframe. To validate this signed invoice: Copy the signature Go to www.keybase.io/verify and paste it there After clicking "verify", you should see a message saying "signed by Bylls" You can check the Bylls keybase profile to see the identity proofs attached to our PGP key You can use any other software to validate the signature and see if it matches the Bylls PGP which is hosted here Notes Everytime the invoice price is refreshed, a new invoice will be created, with a new signed invoice. The last invoice created before you send the payment is the only valid invoice. The invoice is valid for 15 minutes. It is impossible to generate an updated invoice after the payment has been sent. If the invoice has been modified, the signature will not be valid. If it is signed by any other key than the Bylls PGP key, the signature may be valid but the invoice will not be valid. We will subsequently be using the SHA256 hash of the signed invoice for timestamping purposes and you are encouraged to verify yourself that the displayed hash is the correct hash by hashing the signed invoice plain text or text file with the SHA256 function yourself and comparing it to the displayed hash.

These mnemonic words together with a password (optionally) are used to generate a 512 bit seed. The 512 bit seed is also called the "BIP-39 seed". This seed is used to create deterministic wallets. There are two types of deterministic wallets: - Sequential deterministic wallets. - Hierarchical deterministic wallets. SEQUENTIAL DETERMINISTIC WALLET Sequential deterministic wallets generates private keys for example by taking SHA256(seed + n) HIERARCHICAL DETERMINISTIC WALLET Nowadays most wallets are Hierarchical Deterministic (HD) wallets. More information: https://github.com/bitcoin/bips/blob/master/bip-0032.mediawiki Most HD wallet vendors have implemented BIP-32, BIP-39 and BIP-44. These 3 Bitcoin Improvement Proposals are becoming an industry standard. BIP-39 BIP-39 describes the implementation of mnemonic words to generate a 512 bit seed. More information: https://github.com/bitcoin/bips/blob/master/bip-0039.mediawiki BIP-32 BIP-32 describes how you can build a general hierarchical deterministic wallet. More information: https://github.com/bitcoin/bips/blob/master/bip-0032.mediawiki https://bitcoin.org/en/developer-guide#hierarchical-deterministic-key-creation If you want to see how BIP32 is implemented in the bitcoinjs library, see: https://raw.githubusercontent.com/bitcoinjs/bitcoinjs-lib/master/src/hdnode.js Online web application: https://www.mobilefish.com/download/ethereum/hd_wallet.html BIP-32 explains how master keys and master chain code are created from a BIP-39 seed. The chain code is used as entropy in the Child Key Derivation function. Using different index numbers will create different unlinkable child keys from the same parent keys. Repeating the procedure for the child keys using the child chain code will create unlinkable grandchild keys. By changing the chain code, a new node (aka wallet) is created. Extended private (xprv) keys can create a complete branch with child private keys and child public keys Extended public (xpub) keys can only generate public keys. BIP-44 BIP-44 defines a specific logical hierarchy for deterministic wallets based on an algorithm described in BIP-32. More information: https://github.com/bitcoin/bips/blob/master/bip-0044.mediawiki BIP-44 uses the following derivation path: m/purpose'/coin_type'/account'/change/address_index The letter m denotes the master node and all hierarchical levels are separated with slashes (/). m is level 0, purpose is level 1, coin_type is level 2 etc. The purpose scheme is described in BIP-43. Because we are using BIP44 scheme we should use 44'. The apostrophe (for example in purpose') indicates hardened derivation. More information: https://github.com/satoshilabs/slips/blob/master/slip-0044.md account level can be seen as bank account types, for example payment account, savings account etc. change level is also known as "external / internal level" where external (0) is used for addresses that are meant to be visible outside of the wallet (receiving payments) and internal (1) is used for addresses which are not meant to be visible outside of the wallet (signing transactions). address_index is a sequence of addresses starting at 0. BIP-44 XPRV AND XPUB DEMONSTRATION Suppose a webshop wants to receive payments in only in ETH. For each payment received a different Ethereum address must be used. The webshop should use a wallet containing only public keys. The webshop wallet uses a xpub key with derivation path: m/44'/60'/0'/0 This wallet creates the following addresses: m/44'/60'/0'/0/0 m/44'/60'/0'/0/.. The accounting department uses another wallet containing the same public keys AND accompanied private keys. The accounting department can transfer payments made on these public addresses and transfer it to a separate accounting address. This is possible because they have access to the private keys. The accounting department wallet uses a xprv key with the same derivation path: m/44'/60'/0'/0 BIP-32 RISK If a hacker gets it hands on any child private key and the account xpub key, the hacker can recompute the account xprv key and thus have access to every private and public key descending from the account level.

IOTA tutorial 9: Address and checksum
If you like this video and want to support me, go this page for my donation crypto addresses: https://www.youtube.com/c/mobilefish/about This is part 9 of the IOTA tutorial. In this video series different topics will be explained which will help you to understand IOTA. It is recommended to watch each video sequentially as I may refer to certain IOTA topics explained earlier. The procedure to generate IOTA addresses is as follows: IOTA addresses are deterministically generated starting with the seed (81 trytes). Seed (trytes): C9RQF ... QIAWT Convert the seed (81 trytes) to trits (= 81 x 3 = 243 trits) Seed (trits): 0,1,0,0,0,0 ... -1,-1,0,-1,1,-1 Every address has a corresponding key index number. A key index number is an integer starting from 0. Address 0 has key index number 0, address 1 has key index number 1, etc. They key index number always starts with integer 0, and is simply incremented in order to get the next address. The largest key index number allowed is 9007199254740991. This largest key index number is the same as 2^53 - 1, which is the same as the Javascript constant: Number.MAX_SAFE_INTEGER An IOTA seed can generate in total 9007199254740992 addresses. The decimal key index number must be converted to trits. For example the key index number 1 converted to trits looks like: 1,0,0 Next create a subseed by adding the key index number and seed together. subseed = seed + key index number IOTA provides 3 security levels: 1, 2 or 3. A security level determines the number of rounds for hashing, which means that a single seed can have 3 different accounts. A different security level with the same index number, means that you will get a different address. Security level 1, Key size (trits): 6561 x 1 Remark: Used for low security (for very high efficiency). Best for tiny IoT devices that only transact/store small amounts of value. Security level 2, Key size (trits): 6561 x 2 Remark: Used for standard security (for medium performance). Best for regular people's wallets and devices that store higher amounts of value. Security level 3, Key size (trits): 6561 x 4 Remark: Used for full blown quantum proof security that conforms to National Security Agency’s (NSA) recommendations for sensitive material. Good for big value transactions and paranoids. Client libraries, such as iota.lib.js makes it possible to choose another security level. See: https://www.mobilefish.com/services/cryptocurrency/iota_wallet.html By default the IOTA light wallet uses security level 2 and you can not change its security level. If you created an address using security level 1 or 3 this address will not appear in the IOTA light wallet using the same seed. In the next slide a simplistic explanation is given how the subseed is hashed multiple times using the Keccak-384 hash algorithm. The hashing is done in a wrapper class called Kerl. The seed and subseed can differ between the first 1 tryte up to and including 12 trytes. If someone else has exactly the last 69 (= 81 - 12) trytes up to and including 81 trytes of your seed they can see the balance of one or more of your addresses. The probability that someone else happens to have the same last 69 trytes of your seed is very small. Here is the proof: IOTA seed with only 69 trytes has 27^69 = 5.80 x 10^98 possible combinations. For comparison: A Bitcoin private key with 256 bits has 2^256 = 1.15 x 10^77 possible combinations. This means, even if you have an IOTA seed with only 69 trytes it has more possible combinations than a Bitcoin private key. A checksum is an additional 9 trytes added to an address (81 trytes) which can be used to validate the integrity and validity of the address. An address with checksum is 90 trytes long, 81 trytes for the address itself and 9 trytes for the checksum. The procedure to calculate an address checksum is as follows: Start with an IOTA address (81 trytes).Address (trytes): FSAFM ... NVDZC Convert the address (81 trytes) to trits (= 81 x 3 = 243 trits) Address (trits): 1,0,-1,1,0,-1 ... -1,0,0,0,1,0 The address is hashed using the Keccak-384 hash algorithm. Convert the address checksum (243 trits) to trytes (81 trytes): ...PJFNYWVUGKPRTRV Get the last 9 trytes: VUGKPRTRV Append the last 9 trytes to the original address: FSAFM ... NVDZCVUGKPRTRV The address including checksum has a length of 81 + 9 = 90 trytes. The IOTA light wallet: Always creates addresses including the checksum. The addresses are always 90 trytes long. Always requires receive addresses, with valid checksums when making a transaction. The receive addresses must be 90 trytes long.

IOTA tutorial 6: Why you should not reuse an address for outgoing transactions
If you like this video and want to support me, go this page for my donation crypto addresses: https://www.youtube.com/c/mobilefish/about This is part 6 of the IOTA tutorial. In this video series different topics will be explained which will help you to understand IOTA. It is recommended to watch each video sequentially as I may refer to certain IOTA topics explained earlier. Digital signatures are used for authentication, integrity checking and non-repudiation.  Development of quantum computers threatens the security of currently used digital signature algorithms such as Rivest–Shamir–Adleman (RSA) and Elliptic Curve Digital Signature Algorithm (ECDSA). Cryptographers developed a variety of quantum-resistant alternatives of which hash based signatures are the most promising. Hash based signatures are based on so called One Time Signatures (OTS). The term implies that a single public/private key pair must only be used once. Otherwise, an attacker is able to reveal more parts of the private key and spoof signatures. In 1979 Leslie Lamport created a method to construct digital signatures using only cryptographically secure one way hash functions. This method is called the Lamport signature or Lamport One Time Signature (OTS) scheme. Other One Time Signature schemes are the Merkle OTS and Winternitz OTS. The Lamport One Time Signature scheme is very easy to understand and is VERY LOOSELY comparable to Winternitz OTS. For simplicity's sake I will be using the Lamport One Time Signature scheme explaining why you should never reuse an IOTA address for outgoing transactions. Alice uses a random number generator and produces two pairs of 256 random numbers, total 512 numbers. Each random number is 256 bits in size. These random numbers forms the private key. Each of the 512 random numbers are separately hashed, using for example SHA-256. These hashed random numbers forms the public key. Alice has a document (or transaction data) which is hashed using SHA-256. The document hash is of course 256 bits long: 101..011 Alice wants to create a digital signature for her document. She applies the following procedure: - Loop thru each bit (n) of the hash from 0-255. - If the bit is a 0, publish the nth number from pair 0. - If the bit is a 1, publish the nth number from pair 1. - When all bits are looped, destroy all unused numbers from pair 0 and 1. This produces a sequence of 256 random numbers. The digital signature is a sequence of 256 random numbers. After the digital signature is created, delete all unused numbers from the private key. The digital signature consist half of the private key, the other 256 random numbers are still unknown and thus nobody can create signatures that fit other message hashes. Alice sends her document, together with the corresponding digital signature and public key to Bob. Bob wants to verify Alice's document signature. He first hashes the document using SHA-256. The document hash is again: 101..011 Bob follows the same steps when Alice created the digital signature, but instead uses the public key. Bob produces a sequence of 256 hashes picked from Alice's public key. Bob now hashes each of the random number in the digital signature. If both sequence of hash numbers match then the signature is ok. The Lamport signature creates a digital signature which reveals part of the private key. The private key has 512 numbers and using it once will reveal 256 numbers. Using the private key twice weakens the security of the scheme again by half. The probability of an attacker being able to successfully forge a signature for a given message increases from 1/(2^256) to 1/(2^128). A third signature using the same key would increase the probability of a successful forgery to 1/(2^64) and a fourth signature to 1/(2^32), and so on. Please note IOTA's signature scheme is based on the Winternitz One Time Signature (WOTS) scheme and is NOT the same as the Lamport signature scheme. However by using the Lamport One Time Signature scheme I am trying to give you a very simplistic understanding why you should never reuse an IOTA address for outgoing transactions.

HOW TO BUY BITCOIN: Simply Explained - Buying Bitcoin For Beginners
HOW TO BUY BITCOIN: Simply Explained - Buying Bitcoin For Beginners ★ BUY BITCOIN HERE ➤ http://iqopts.com/bitcoin These exchanges vary within the fees you pay out them for your transaction buy bitcoin, the countries they can be found in, as well as the Restrict of simply how much you can buy in one transaction. The journal encourages authors to digitally indication a file hash of submitted papers, that can then be timestamped in to the bitcoin blockchain. Authors are questioned to incorporate a personal buy bitcoin handle in the very first web page of their papers. As it is largely only a series of keys, you can find a wide variety of buy bitcoin wallet varieties with different levels of protection. All of them have their benefits and drawbacks. You may purchase them in a number of methods, ranging from tough money to credit rating and debit cards to wire transfers, or Despite other cryptocurrencies, according to who you might be buying them from and where you reside. The following selection for buying & selling Bitcoin is a Limit Purchase. That has a limit get you can buy or offer or specific quantity of buy bitcoin at a provided selling price or better. To submit a Restrict purchase it is possible to change the cost for every buy bitcoin to something you prefer in the shape underneath and click on the Acquire or Provide button, When you click the button the Restrict purchase will be submitted as well as your buy will likely be open right up until either a trade occurs or else you terminate the purchase. Within a pool, all participating miners receives a commission anytime a collaborating server solves a block. This payment relies on the amount of operate a person miner contributed to help you see that block. You will find a quite neat website which shows you The present BTC/USD fee after all of Virwox’s costs. I’m not sure check here how reliable the location is however, you can test it out for yourself below. It's also wise to ask the vendor if they like to get paid out in hard cash or by using an online payment provider. Some seller may perhaps permit you to use a PayPal account to pay for, even though most vendor want non-reversible income as payment. The aforementioned Local Bitcoins also allows you to use cash, as connecting customer and vendor lets you probably satisfy them in particular person and shell out them immediately in cash. Furthermore, you'll find web sites like Bitquick and Paxful, which connect purchaser and seller in a means where by the vendor presents financial institution details that permit the client generate a dollars deposit within the lender. Physical wallets store offline the credentials important to invest bitcoins. A person notable instance was a novelty coin Using these credentials printed over the reverse facet. Paper wallets are merely paper printouts. PayPal would not like bitcoin, because the bitcoin network is in direct Level of competition to it. They may ban accounts which have anything at all to carry out with Bitcoins, and freeze their equilibrium. You could develop a wallet by setting up the Bitcoin shopper[twelve], that's computer software which powers the currency. However, In the event your Pc is hacked by a virus or hackers or in the event you misplace the files, you could drop your Bitcoins. Generally again up your wallet to an exterior disk drive to stay away from getting rid of your Bitcoins. Users will have to build adverts or Find other ads to find sellers of bitcoin. Bitcoin-OTC is considerably challenging and hard to use, but may be the only choice for users in certain nations around the world without an Trade. Pros Complete clientele check the validity of mined blocks, protecting against them from transacting on a series that breaks or alters community procedures. Due to its size and complexity, downloading and verifying the entire blockchain isn't suited to all computing units.

Free Giveaway Contest Link:- https://goo.gl/Y9UgSq Aadhar Card Virtual Id की सुविधा सुरु | How to generate Virtual Id | बिना Aadhar Card होगा सारा काम https://www.youtube.com/watch?v=ej5jrprAmjI&t=9s In this video i am going to show you "what is Virtual Id and How to generate Virtual Id? The Unique Identification Authority of India (UIDAI) has mandated the use of Virtual Identification from July 1. Virtual Identification is a 16-digit random number that is tagged to one's Aadhaar number. The owner of the Aadhaar number has complete control over this number and can generate, replace or revoke it at any time. Virtual ID can be given in place of a person's original Aadhaar number from July 1 onward. There are two types of an Authentication User Agency -- Local AUA, which involves limited KYC, and Global AUA, which can access e-KYC using the Aadhaar number. AUAs are government entities or other public and private legal agencies registered in India that makes use of Aadhaar authentication services provided by the UIDAI. Local AUAs include non-life insurance companies, prepaid payment instruments (PPIs), non-bank financial institutions (NBFCs) and telecom operators. All banks, including regional banks, small finance banks, commercial banks, rural banks, cooperative banks and payments banks, come under the global AUA category. Life insurance companies and the National Payments Corporation of India (NPCI) are also global AUAs. However, use of Virtual ID for availing services of global AUAs is optional for all users.

Victory Crypto - Bitcoin, Ethereum, Bitcoin Cash, LiteCoin, NEO, DASH and other cryptocurrencies
http://bit.ly/2R9NkpI Victory Crypto - Bitcoin, Ethereum, Bitcoin Cash, LiteCoin, NEO, DASH and other cryptocurrencies What is Crypto Victory? http://bit.ly/2R9NkpI As a platform that’s packaged as an “Exclusive Cryptocurrency Trading Community” with subscription plans for its members, Crypto Victory is undoubtedly a step away from the quintessential types. And it is rightly so given that it is more than a crypto investment marketplace. Mostly, it is where one can get precious market updates, get trained and educated and also taken on step-by-step technical analysis on the way the crypto industry behaves. Crypto Victory is a members-only group where those who would solemnly love to be part of the cryptocurrency train make their dreams a reality. It thrives on the fact that Bitcoin, Ethereum, Bitcoin Cash, LiteCoin, NEO, DASH and other cryptocurrencies are very volatile and hard to predict how they can behave. #victorycryptoreview Crypto App Victory Crypto Review Victory Crypto Program Victory Crypto System Victory Crypto Team Victory Crypto crypto app, crypto apple watch, crypto application, crypto app wallet, crypto app mobile, crypto app review, crypto app shark tank, crypto apparel, crypto app for windows, delta crypto app tutorial, earn crypto app, crypto trading app android, crypto miner app android, best crypto app, bison app crypto, crypto.com app, crypto cash app, crypto coin miner app, crypto crunch app, crypto diamonds app, delta app crypto, crypto diamonds app hack, crypto applet failed to validate certificate, jason appleton crypto, jason appleton crypto crow, best crypto app for android, crypto tracker app in hindi, crypto mining app, crypto miner app, crypto money app payment proof, crypto millionaire app, crypto pro app, crypto pop app, crypto portfolio app, robinhood app crypto, crypto rewards app, crypto signals app review, crypto trading app, shark tank crypto app, crypto trader app, cryptotab app, crypto viewer app crypto, crypto news, crypto trading, crypto analysis, crypto bot crypto best, crypto best indicators, crypto best buys, crypto best investment, crypto best buys 2018, best crypto wallet, best crypto wallet 2018, best crypto trading bot, best crypto trading platform, best crypto exchange, best crypto brokers, best free crypto trading bot, best crypto books, best crypto arbitrage bot, best cryptocurrency, best crypto coin, best crypto mining companies, best low cap crypto, best crypto wallet canada, best crypto credit card, best cryptocurrency youtuber, best crypto coin exchange, best cheap crypto, best desktop crypto wallet, best crypto dice, best crypto dex, best crypto exchange uk, world best crypto exchange, best australian crypto exchange, best crypto exchange canada, best crypto experts, best crypto faucets 2018, best crypto for 2019, best indicators for crypto trading, best bot for crypto trading, best free crypto mining sites, best free crypto wallet, best crypto faucets, best strategy for crypto trading, best crypto games, best crypto gambling sites, best crypto signal group, best crypto hardware wallet, best crypto hard wallet, best crypto to hodl, best long term crypto, best long term crypto investments, best crypto miner, best crypto mining rig, best crypto mining app, best crypto masternodes, best crypto news sources, best crypto news, best new crypto, best crypto now, best crypto october 2018, best online crypto wallet, best offline crypto wallet, best crypto october, best crypto portfolio, best crypto projects, best crypto platforms 2018, best crypto passive income, best crypto robot, best crypto signals, best crypto september 2018, best scalping strategy crypto, best crypto trading, best crypto to buy, best crypto to invest, best crypto trading app, best crypto indicators tradingview, best crypto under $1, best crypto wallet app, best crypto trading websites, best crypto youtubers, best crypto under 1 cent, best crypto investments 2018
How Does The Bitcoin Network Know You Have The Right Private Key?
When you send Bitcoin from one account to another how does the bitcoin network know you have the right private key? How does Bitcoin authorize and validate transactions to ensure only people with the private keys can send money? What is stopping anyone sending money from one account to another and how do the private and public keys work?

Zerocash: Addressing Bitcoin's Privacy Problem
A Google TechTalk, 8/28/17, presented by Alessandro Chiesa Abstract: In Bitcoin, a payment's details are broadcast in the clear, so that anyone can verify its validity. Unfortunately, this violates user privacy and sacrifices coin fungibility. I will describe the Zerocash protocol, which uses zero knowledge proofs to achieve privacy-preserving payments in a Bitcoin-like system. This protocol was recently deployed in the wild, as part of the cryptocurrency Zcash. About the Speaker: Alessandro Chiesa is an assistant professor in the Department of Electrical Engineering and Computer Science at UC Berkeley. His research spans the areas of complexity theory, cryptography, and security, and focuses on the theoretical foundations and practical implementations of cryptographic proof systems such as zero knowledge proofs. He is a co-inventor of Zerocash and co-founder of Zcash. He is an author of libsnark, the leading open-source library for succinct zero knowledge proofs. He has received a Ph.D. in computer science from MIT in 2014, and B.S. degrees in computer science and in mathematics from MIT in 2009.

ep 13: How is bitcoin "locked" to an address - OP_CHECKSIG, locking scripts, signatures, UTXO chain
I've been meaning to make this video for a long time. It follows on from episode 12 which talks about locking and unlocking scripts and here we finish off the explanation with a look into how digital signatures are used to ensure that only the intended recipient of UTXO (unspent transaction output) can actually spend that UTXO in new transactions. Essentially the transaction is defined and then hashed and that hash is encrypted with the private key of the transaction creator (spender) - that becomes a signature of the transaction - and is used by all the nodes in the network to validate the transaction, and ensure that corresponding public key is the one used as the beneficiary of the output referenced in the transaction inputs.
