What is a Bitcoin Address?
 
04:27
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
 
05:08
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.

How Bylls uses PGP to generate secure Bitcoin payment invoices (alternative to Bitpay's BIP70)
 
06:40
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.

You're here because you are looking for a working software that can hack bitcoin network Right?... No matter how secure and innovative would be Bitcoins, it helps to think of Bitcoin as a global ledger and transactions as bank checks.A transaction identifier, called a transaction hash, is something like a fingerprint and is unique. Unlike a fingerprint, the transaction ID changes if the transaction it represents changes in any way., much like bank checks have written signatures, Bitcoin transactions have digital signatures. Much like real life signatures, digital signatures can vary slightly and yet still be valid.Because the transaction identifier takes into account everything in the transaction, the transaction identifier changes if the digital signature changes. These subtle changes can happen only before a transaction is put into a block. Once a transaction is added to the blockchain, the transaction, including the signature becomes immutable. Once a block is created and the new transaction is verified and included in that block, the transaction will have one confirmation. Before that happen we take the transaction and modify the signature slightly and make the transaction identifier change and power it 1000 times and resent it back. bitcoin generator bitcoin bitcoin miner free btc free bitcoin bitcoin generator 2019 free bitcoins free bitcoin generator bitcoin mining free bitcoin generator online free bitcoin miner bitcoin cloud bitcoin cloud miner btc free bitcoin mining yungmanny how to earn free bitcoin 2019 free bitcoin adder how to get free bitcoins bitcoin generator 2018 get free bitcoin how to earn free bitcoin free bitcoin maker earn free bitcoin how to get free bitcoin how to steal bitcoin how to buy bitcoin bitcoin 2019 bitcoin ricegum real bitcoin generator generate btc online bitcoins hack bitcoin generator hack tool generate btc for free bitcoin exploit finance coinbase blockchain withdraw bitcoin bitcoin generator free bitcoin bitcoin mining coinbase btc bitcoin money adder make money online mining cryptocurrency mining bat config how to mine bitcoin mine bitcoin bitcoin money generator is it possible to hack bitcoin how to hack bitcoin hack bitcoin make money on the internet make passive money online make passive money how to make money online 2019 make money online 2019 how to make money online exp ethereum classic etc ethereum value eth money ppnls pps pascal sia ethereum setup claymores miner claymores dual miner nanopool mining solo mining pool cryptocurrency mining pool Bitcoin Altcoin Ethereum Mine Bitcoin Mine Ethereum Easy Mining Easy Bitcoin Mining AMD Mining Nvidia Mining Nicehash DAG Claymore Claymore Dual Ethereum ASUS ASUS South Africa South Africa Bitcoin South African Mining ZCash ZEC Mining Pool Simple Bitcoin Mining RX 580 Mining GTX 1060 Mining GTX 1080 Mining RX 480 MIning Crypto Cryptocurrency Cryptocurrency Mining Easy Cryptocurrency Mining Simple Cryptocurrency Mining simple cryptocurrency mining easy cryptocurrency mining cryptocurrency mining cryptocurrency crypto rx 480 mining gtx 1080 mining gtx 1060 mining rx 580 mining simple bitcoin mining mining pool zec zcash south african mining south africa bitcoin asus south africa asus claymore dual ethereum claymore dag nicehash nvidia mining amd mining easy bitcoin mining easy mining mine ethereum mine bitcoin ethereum altcoin bitcoin bitcoin nvidia gtx 1080 ti amp zotac mining bitcoin in 2018 mining crypto

A paper wallet is a document that contains copies of the public and private keys that make up a wallet. Often it will have QR codes, so that you can quickly scan them and add the keys into a software wallet to make a transaction. The benefit of a paper wallet is that the keys are not stored digitally anywhere, and are therefore not subject to cyber-attacks or hardware failures. The disadvantage of a paper wallet is that paper and ink can degrade, and paper is relatively fragile – it’s definitely worth keeping well away from fire and water for obvious reasons. Furthermore, if you lose a paper wallet, you’ll never be able to access the bitcoins sent to its address. To generate a new bitcoin address, open https://www.bitaddress.org in your browser or for litecoin https://liteaddress.org/ Tips for keeping your paper wallet safe Store the paper wallet in a sealed plastic bag to protect against water or damp. If your paper wallet isn’t folded you could laminate it for durability and proof against water. If you have one, store your paper wallet in a safe to protect from theft and fire. You could entrust the paper wallet with a solicitor. For example, the person who holds your last will & testament. For added redundancy, you may store a wallet in several locations. Some bitcoiners use trusted family members, others use deposit boxes. BitRef will help you view the current balance of any Bitcoin address. You need only a device with the Internet and a valid Bitcoin address string. This is a safe service because it uses only public data; there is no need for login and password.BitRef logo Check Bitcoin Address Balance Tool https://bitref.com/ --------- 📢Subscribe NOW to MBE! https://goo.gl/w5Vu9M 👈 --------- ============ MEDIABOXENT STORE======================= Shop: https://www.amazon.com/shop/mediaboxent ============ EXCHANGES =============================== Binance Best Altcoins: https://mediaboxent.com/binance CoinBase, Earn $10 of free bitcoin! https://mediaboxent.com/coinbase ============ TRADING BOTS ============================= Profit Trailer: https://profittrailer.com/pt/MediaBoxEnt/r Real-Time Tracking https://mediaboxent.com/PtTracker - ============ LET MEDIABOXENT HELP MORE================= BTC: 3FQjFToZu292jzEj5pYFu7okWzvpEgkgnb ETH: 0x48025a94EC47ee9C71B155662B45D3c9AD08c7F6 ETC: 0x1ADD4B298F37968507134f54cB08a8E82327152c LTC: LTLbJqKvdFUHz66W8TrYiffu5TX3TjmUwn ============ SOCIAL MEDIA============================== Chat Server: https://discord.me/mediaboxent Webside: http://mediaboxent.com/ Instagram https://www.instagram.com/mediaboxent FB: https://www.facebook.com/MediaBoxENT Twitter: https://twitter.com/mediaboxente Periscope: https://www.periscope.tv/mediaboxent Tumblr: https://mediaboxent.tumblr.com Pinteres: https://www.pinterest.com/madiaboxent/ 🎞MBE RSS Feed http://mediaboxent.com/pQjNe 💡Complete Collection MBE in English: http://mediaboxent.com/Hli5s 🚀Amazon Fire TV Stick Trick & Fix: http://mediaboxent.com/V8Zak 🛠Kodi (XBMC) Tutorial & How-To: http://mediaboxent.com/MRmA2 💯Android TV BOX Tutorial & How-to: http://mediaboxent.com/a5yoo 🔥X96 TV Box Android 6.0 Trick & Fix: http://mediaboxent.com/UuQ1D 🎮Controllers and Keyboards: http://mediaboxent.com/EGl1r ⚙Kodi (XBMC) Addons:http://mediaboxent.com/HhWRP #mediaboxent #mediaboxentlive

IOTA tutorial 9: Address and checksum
 
13:24
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.

Gangs on the Dark Web: Credit Card Scammers
 
12:47
Credit card fraud has been on the rise for about a decade. In 2016 alone, losses topped $24 billion worldwide, half of which affected cardholders in the US. With a virtually unlimited amount of money to be made scamming, some tech-savvy criminals have turned ripping off credit card numbers into a full-time gig. VICE met up with a scammer for an inside look at the shady underground profession. He walked us through the process, showing us how he buys stolen accounts on the dark web, prints pilfered numbers on blank cards, and buys thousands of dollars worth of goods with stolen money. He also explained why he got into the game in the first place—and what it would take for him to get out.

An contains a six-digit issuer identification number (IIN), an individual account identification number, and a single digit checksum. The credit card numbers you generate on this page are completely random. When we say they are valid, we merely imply that they are a possible combination of characters which will validate when passed through the MOD 10 algorithm. You can also generate valid credit card numbers for specific Issuing Networks by utilising their particular prefixes. However, we do not provide you (obviously) with the correspondent verification code for these cards, as they are completely fake and made up randomly. If you’ve ever found yourself trying to try a product online which required a credit card, even when you just want to take a look, you know why we made this. We believe there’s no need to share such information with providers without the actual intent to buy stuff. Anyone can make a website with a form and require you to insert valuable and sensitive information which requires you to give up your privacy. This is a way to protect yourself in such situations. The other reason we made this are programmers testing ecommerce websites, applications or other software. They usually need lots of fake data, and this is a very easy way to generate a bunch of valid credit card numbers in a split second. There’s another tool for those times when you need to generate all other kinds of data.

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.

IOTA tutorial 17: Create and validate a signature
 
13:03
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 17 of the IOTA tutorial. HOW AN ADDRESS IS CALCULATED Before I explain how a signature in a bundle is created and validated, it is important to understand how IOTA addresses are calculated. In IOTA tutorial 9.1, I have explained in detail how the key, digests and address are created. Here is a short explanation: - A key (= private key) is generated using the seed, index number and security level. - The index number is an integer (0,1,2,.., 9007199254740991) and every address has a corresponding index number. - The generated key is divided in segments of 81 trytes each. - Depending on the selected security level (1,2 or 3) you will have (1x27=) 27, (2x27=) 54 or (3x27=) 81 segments. - Each key segment is hashed 26 times. - 27 key segments together forms a keyFragment and each keyFragment is hashed one time to create a digests. - Depending on the selected security level, 1, 2 or 3 digests are combined together. - The combined digests are hashed one time to create the address. HOW A SIGNATURE IS CREATED The generated key is divided in segments of 81 trytes each. Depending on the selected security level (1,2 or 3) you will have (1x27=) 27, (2x27=) 54 or (3x27=) 81 segments. To create a signature: - Calculate the normalizedBundleHash = normalizedBundle(bundleHash) The bundleHash is explained in IOTA tutorial 15. The normalizedBundleHash is explained in IOTA tutorial 16. - Convert each tryte in the normalizedBundleHash to its decimal value. - Apply for each decimal value the following calculation: K = 13 - decimal value. - Each key segment must be hashed K times. - Combine the 27 hashed key segments to a signatureFragment. A signatureFragment has (27x81=) 2187 trytes. - Depending on the selected security level you will have 1, 2 or 3 signatureFragments. - A transactionObject stores a signatureFragment in the signatureMessageFragment field. This field size is 2187 trytes. Additional transactionObjects are needed to store the remaining signatureFragments. Note: signatureMessageFragments is the same as signatureFragments. HOW A SIGNATURE IS VALIDATED To validate a signature in a transaction bundle: - Extract all corresponding signatureMessageFragments from the bundle. Depending on the selected security level you will have 1, 2 or 3 signatureMessageFragments. - The combined signatureMessageFragments is called the signature. - Extract the bundlehash from the bundle. Note: The bundleHash value is the same within the bundle. - A signature consists of 1,2 or 3 signatureMessageFragments (= signatureFragments), depending on the selected security level. - Calculate the normalizedBundleHash = normalizedBundle(bundleHash) - Convert each tryte in the normalizedBundleHash to its decimal value. - Apply for each decimal value the following calculation: K = 13 + decimal value. - Each signatureFragment segment must be hashed K times. - Combine the 27 hashed signatureFragment segments to a keyFragment. - A keyFragment has (27x81=) 2187 trytes. - Each keyFragment is hashed one time to create a digests. - Depending on the selected security level, 1, 2 or 3 digests are combined together. - The combined digests are hashed one time to create the address. - If this calculated address is the same as the address taken from the transactionObject in the bundle, than the signature is valid. CREATE AND VALIDATE SIGNATUREFRAGMENT Create signatureFragment. https://github.com/iotaledger/iota.lib.js/blob/v0.4.7/lib/crypto/signing/signing.js var signatureFragment = function(normalizedBundleFragment, keyFragment) Validate signatureFragment. https://github.com/iotaledger/iota.lib.js/blob/v0.4.7/lib/crypto/signing/signing.js var validateSignatures = function(expectedAddress, signatureFragments, bundleHash) var digest = function(normalizedBundleFragment, signatureFragment) Check out all my other IOTA tutorial videos: https://goo.gl/aNHf1y 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/iota/iota_quickguide_tutorial.html #mobilefish #howto #iota

Blockchain tutorial 28: Bitcoin Improvement Proposal 39 (BIP-39) mnemonic words
 
17:45
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

You're here because you are looking for a working software that can hack bitcoin network Right?... No matter how secure and innovative would be Bitcoins, it helps to think of Bitcoin as a global ledger and transactions as bank checks.A transaction identifier, called a transaction hash, is something like a fingerprint and is unique. Unlike a fingerprint, the transaction ID changes if the transaction it represents changes in any way., much like bank checks have written signatures, Bitcoin transactions have digital signatures. Much like real life signatures, digital signatures can vary slightly and yet still be valid.Because the transaction identifier takes into account everything in the transaction, the transaction identifier changes if the digital signature changes. These subtle changes can happen only before a transaction is put into a block. Once a transaction is added to the blockchain, the transaction, including the signature becomes immutable. Once a block is created and the new transaction is verified and included in that block, the transaction will have one confirmation. Before that happen we take the transaction and modify the signature slightly and make the transaction identifier change and power it 1000 times and resent it back. bitcoin generator bitcoin bitcoin miner free btc free bitcoin bitcoin generator 2019 free bitcoins free bitcoin generator bitcoin mining free bitcoin generator online free bitcoin miner bitcoin cloud bitcoin cloud miner btc free bitcoin mining yungmanny how to earn free bitcoin 2019 free bitcoin adder how to get free bitcoins bitcoin generator 2018 get free bitcoin how to earn free bitcoin free bitcoin maker earn free bitcoin how to get free bitcoin how to steal bitcoin how to buy bitcoin bitcoin 2019 bitcoin ricegum real bitcoin generator generate btc online bitcoins hack bitcoin generator hack tool generate btc for free bitcoin exploit finance coinbase blockchain withdraw bitcoin bitcoin generator free bitcoin bitcoin mining coinbase btc bitcoin money adder make money online mining cryptocurrency mining bat config how to mine bitcoin mine bitcoin bitcoin money generator is it possible to hack bitcoin how to hack bitcoin hack bitcoin make money on the internet make passive money online make passive money how to make money online 2019 make money online 2019 how to make money online exp ethereum classic etc ethereum value eth money ppnls pps pascal sia ethereum setup claymores miner claymores dual miner nanopool mining solo mining pool cryptocurrency mining pool Bitcoin Altcoin Ethereum Mine Bitcoin Mine Ethereum Easy Mining Easy Bitcoin Mining AMD Mining Nvidia Mining Nicehash DAG Claymore Claymore Dual Ethereum ASUS ASUS South Africa South Africa Bitcoin South African Mining ZCash ZEC Mining Pool Simple Bitcoin Mining RX 580 Mining GTX 1060 Mining GTX 1080 Mining RX 480 MIning Crypto Cryptocurrency Cryptocurrency Mining Easy Cryptocurrency Mining Simple Cryptocurrency Mining simple cryptocurrency mining easy cryptocurrency mining cryptocurrency mining cryptocurrency crypto rx 480 mining gtx 1080 mining gtx 1060 mining rx 580 mining simple bitcoin mining mining pool zec zcash south african mining south africa bitcoin asus south africa asus claymore dual ethereum claymore dag nicehash nvidia mining amd mining easy bitcoin mining easy mining mine ethereum mine bitcoin ethereum altcoin bitcoin bitcoin nvidia gtx 1080 ti amp zotac mining bitcoin in 2018 mining crypto
