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.

Which cryptocurrency blockchain has the most transactions per day?
 
12:57
Would you join us in discovering which blockchain has the most transactions daily because knowing this helps determine which cryptocurrency truly is valuable and which is likely to be pure speculation? The reason fiat currencies like USD have value is the ability to transact. A key indication of the true value of a currency is how much it is being used. With cryptocurrencies the same rule applies because a currency that has many users sending and receiving money is worth buying while anything that has a low amount of activity is likely overvalued and best to sell. For example, Ethereum actually has more transactions than Bitcoin today but Steem has more than both of them combined even with a fraction of the number of users!

Use a Multisig Wallet to Protect your Bitcoin Transactions
 
03:27
As Bitcoin and other cryptocurrencies gain popularity as a mode of payment transfer, it has become common for the average Bitcoin user to be scammed by an anonymous identity who requests payment for some work is then never heard from again. . The decentralized nature of cryptos certainly has a tradeoff – unlike a credit card or bank transaction that can be reverted, a cryptocurrency transfer once confirmed is permanently recorded on the Blockchain. This is where multi-signature (multisig) wallets come to our rescue.. A multisig wallet is a special bitcoin wallet that requires more than one private key to sign transactions. Most multi-signature setups usually involve three parties – the sender of the payment, the recipient, and an escrow agent. Each of the three parties holds one private key, and to send any transaction, at least two private keys must be used.. Typically, escrow agents are trusted members of the Bitcoin community or registered entities who arbitrate any disputes that may arise. Therefore, the buyer is protected in case the seller turns out to be fraudulent, and the seller, too, is assured of payment even if the buyer refuses to pay.. CREATING A MULTISIG WALLET. There are many ways to create a multisig wallet. In fact, most Bitcoin clients support the multisig protocol. Electrum and Armoury are used by many crypto holders because they have provisions for advanced settings like custom fees etc. which are great for power users. . BitGo is another popular option for those who prefer a web-based client. In my opinion, however, CoPay offers the most streamlined, easy to use interface, that is usable by anyone, even a new Bitcoin user. So for the purposes of this tutorial, I will be using. Step 1: Download CoPay. Head over to the CoPay website and download the appropriate installer for your platform. A great advantage of using CoPay is its support for nearly all desktop and mobile platforms (iOS and Android included).. Step 2: Start by setting up your personal wallet. Open the installed app, and run through the quick setup to create your personal wallet. This will involve typing in an email address for transaction notifications, and noting down a mnemonic phrase that can be used as a backup in case CoPay is accidentally deleted from your computer.. Step 3: Create a Shared Wallet. Multisig wallets are called ‘Shared Wallets’ in CoPay. Once your personal wallet is set up, click on the shared wallet option on the CoPay home screen to create a multisig wallet. You will be presented with a screen where you can configure the wallet with the number of co-payers, the number of signatures required etc. depending on your needs.. Step 4: Share the CoPay invite with others. The last step is to share your multisig wallet with the 2 other parties. Send them the CoPay code displayed or ask them to scan the QR code. That’s it! Your CoPay escrow is set up! Now everytime someone requests a payment, you will receive a notification to confirm the transactio

KCN Confirmation queues on bitcoin blockchain
 
00:54
Partner: CRYPTOPIA - https://www.cryptopia.co.nz/ Number of unconfirmed Bitcoin transactions keeps increasing, a lot of users are left frustrated. Blockchain Consultant, Timothy Suggs notes the possible reasons for the increased delays are exponential growth and acceptance of the platform and political reason. By political it means that, there are actors in the system sending thousands of transactions to themselves in order to add leverage to the block size debate. Suggs notes that to speed up their transaction time users can increase their fee or engage in what can be referred to as a round trip. For example, if you are using an exchange like Poloniex or Bittrex, simply trade your Bitcoin for an asset like Expanse and send it to your destination.

Bitcoins are a commonly-used currency among cyber criminals for exchanging goods and services and receiving payments from ransomware. While cryptocurrency claims to promote anonymity, the nature of the blockchain’s public ledger means that criminal activities can be traced and correlated. This presentation will cover a brief high-level overview of how transactions on the blockchain work and will focus on how to apply this knowledge in order to both manually and automatically map out transactions, associate bitcoin addresses, and identify potential cybercriminal-owned bitcoin wallets with the goal of providing context to the scale and duration of a campaign impacting your enterprise. Examples will include identifying a Locky affiliate’s infrastructure, attributing the Shark/Atom ransomware, and identifying “bitcoin exchanges” on the blockchain.

The Bitcoin and Blockchain Technology Explained
 
06:16
A block chain is a transaction database shared by all nodes participating in a system based on the Bitcoin protocol. A full copy of a currency's block chain contains every transaction ever executed in the currency. With this information, one can find out how much value belonged to each address at any point in history. ------------------------------------------------------------------- BUY BITCOIN SAFELY HERE: http://bit.ly/BuyBitcoinNow ------------------------------------------------------------------- REGISTER FOR A COINBASE ACCOUNT: http://bit.ly/CoinbaseBitcoinSignup ------------------------------------------------------------------- Every block contains a hash of the previous block. This has the effect of creating a chain of blocks from the genesis block to the current block. Each block is guaranteed to come after the previous block chronologically because the previous block's hash would otherwise not be known. Each block is also computationally impractical to modify once it has been in the chain for a while because every block after it would also have to be regenerated. These properties are what make double-spending of bitcoins very difficult. The block chain is the main innovation of Bitcoin. Honest generators only build onto a block (by referencing it in blocks they create) if it is the latest block in the longest valid chain. "Length" is calculated as total combined difficulty of that chain, not number of blocks, though this distinction is only important in the context of a few potential attacks. A chain is valid if all of the blocks and transactions within it are valid, and only if it starts with the genesis block. For any block on the chain, there is only one path to the genesis block. Coming from the genesis block, however, there can be forks. One-block forks are created from time to time when two blocks are created just a few seconds apart. When that happens, generating nodes build onto whichever one of the blocks they received first. Whichever block ends up being included in the next block becomes part of the main chain because that chain is longer. More serious forks have occurred after fixing bugs that required backward-incompatible changes. Blocks in shorter chains (or invalid chains) are not used for anything. When the bitcoin client switches to another, longer chain, all valid transactions of the blocks inside the shorter chain are re-added to the pool of queued transactions and will be included in another block. The reward for the blocks on the shorter chain will not be present in the longest chain, so they will be practically lost, which is why a network-enforced 100-block maturation time for generations exists. These blocks on the shorter chains are often called "orphan" blocks. This is because the generation transactions do not have a parent block in the longest chain, so these generation transactions show up as orphan in the listtransactions RPC call. Several pools have misinterpreted these messages and started calling their blocks "orphans". In reality, these blocks have a parent block, and might even have children. Because a block can only reference one previous block, it is impossible for two forked chains to merge. • How do Bitcoin Transactions Work? http://www.coindesk.com/information/how-do-bitcoin-transactions-work/ ------------------------------------------------------------------- DID YOU LIKE THIS VIDEO? ------------------------------------------------------------------- Enjoy this video?

How to remain anonymous while using bitcoin
 
01:55
Bitcoin is a cryptocurrency that can help protect your identity when making purchases online. But it's not foolproof. Kevin Mitnick, one of the world's most famous hackers and author of the book "The Art of Invisibility," offers some tips that will help you remain anonymous. Following is a transcript of the video: The whole idea of really being truly invisible is a disconnect between you as the user and your first connection to the internet. If you use bitcoin, there is a blockchain. And the blockchain is really traceable. In fact, during the trial of Ross Ulbricht, the guy that was accused of running the drug emporium Silk Road, they were able to trace millions of dollars of transactions to the wallet on his computer. So to try to anonymize bitcoin, you can go to a bitcoin ATM. You could buy it from person-to-person on the street, which is probably the safest way if you're using a phone that's not really registered to you. Like a burner device. Or you could use services that launder bitcoin. So you could buy bitcoin, for example, with a pre-paid card. You can go to any of the pharmacies, buy prepaid gift cards. You could go to certain sites and actually convert that to bitcoin for a large fee, and then you could go take that bitcoin and launder it even further. They have laundering sites. So you basically send bitcoin to them, and they'll mix it with other people's bitcoins, and eventually send you bitcoin back with a small fee that's deducted from the transaction. And then, when you have this clean bitcoin, you could use it, for example, to top up data cards or to purchase email accounts, where you have to sign up for a subscription, to make it really hard to trace you as the anonymous user behind it.

How Bitcoin Can Help Track Down Criminals (HBO)
 
04:02
People like to think that using Bitcoin makes your transactions anonymous. But buried in last month’s special counsel indictment of 12 alleged Russian spies is an explanation of how law enforcement used the blockchain, the network which facilitates bitcoin transactions, to track and identify the suspects using their cryptocurrency transactions. Because every bitcoin transaction is recorded on a public ledger, law enforcement can trace back bitcoins to its origins. Once you trace enough steps back, an investigator could typically find some place where bitcoins were purchased or where bitcoins were used to purchase a service. This is key, because bitcoin sellers, like Coinbase, or places that sell services, typically require some personal information. With the power of subpoena, law enforcement could obtain that personal information, making it easier to link a bitcoin transaction to a real person, interad of a random series of numbers and letters. One blockchain developer, Tim Cotten, was even able to trace Bitcoin purchases back to Russia’s intelligence agency, the GRU, using only public information. And he agreed to show VICE News how almost anyone with a bitcoin wallet could do something similar.

Bitcoin inside information for 2018 💰💰💰 | Bitcoin 5000 BVK
 
08:04
website: http://bitcoin5000.org exchange: graviex.net/markets/bvkbtc #bitcoin #bitcoin5000 #cryptocyrrency Bitcoin is a decentralized digital currency that enables instant payments to anyone, anywhere in the world. Bitcoin uses peer-to-peer technology to operate with no central authority: transaction management and money issuance are carried out collectively by the network. The original Bitcoin software by Satoshi Nakamoto was released under the MIT license. Most client software, derived or "from scratch", also use open source licensing. Bitcoin is the first successful implementation of a distributed crypto-currency, described in part in 1998 by Wei Dai on the cypherpunks mailing list. Building upon the notion that money is any object, or any sort of record, accepted as payment for goods and services and repayment of debts in a given country or socio-economic context, Bitcoin is designed around the idea of using cryptography to control the creation and transfer of money, rather than relying on central authorities. Bitcoins have all the desirable properties of a money-like good. They are portable, durable, divisible, recognizable, fungible, scarce and difficult to counterfeit. Bitcoin is P2P electronic cash that is valuable over legacy systems because of the monetary autonomy it brings to its users. Bitcoin seeks to address the root problem with conventional currency: all the trust that's required to make it work -- Not that justified trust is a bad thing, but trust makes systems brittle, opaque, and costly to operate. Trust failures result in systemic collapses, trust curation creates inequality and monopoly lock-in, and naturally arising trust choke-points can be abused to deny access to due process. Through the use of cryptographic proof, decentralized networks and open source software Bitcoin minimizes and replaces these trust costs. Bitcoin Transactions are: Permissionless and borderless. The software can be installed by anybody worldwide. Do not require any ID to use. Making it suitable for the unbanked, the privacy-conscious, computers or people in areas with underdeveloped financial infrastructure. Are censorship-resistant. Nobody is able to block or freeze a transaction of any amount. Irreversible once settled, like cash. (but consumer protection is still possible.) Fast. Transactions are broadcasted in seconds and can become irreversible within an hour. Online and available 24 hours a day, 365 days per year. Bitcoin can also be a store of value, some have said it is a "swiss bank account in your pocket". Stored Bitcoins: Cannot be printed or debased. Only 21 million bitcoins will ever exist. Have no storage costs. They take up no physical space regardless of amount. Are easy to protect and hide. Can be stored encrypted on a hard disk or paper backup. Are in your direct possession with no counterparty risk. If you keep the private key of a bitcoin secret and the transaction has enough confirmations, then nobody can take them from you no matter for what reason, no matter how good the excuse, no matter what.

Blockchain 101 Ep 16 - What's the fee for Bitcoin transactions?
 
01:07
Bitcoin transaction fees give Bitcoin miners an incentive to include transactions into their blocks and provide sufficient hashing power, securing the Bitcoin network. Some also call it “miner fees”. When making a transaction over the Bitcoin network, one usually pays for miners to facilitate the transaction. The fee tends to be around 0.0001-0.0015 Bitcoin. Block sizes are limited and can only support limited number of transactions. Therefore, miners will prioritize transactions that pay higher fees. A higher fee means the transaction can be processed sooner. This raises the threshold of making Bitcoin transactions and also effectively protects the blockchain from spams while ensuring miners still have the incentive to maintain the Bitcoin network even after all the Bitcoins are mined.

Bitcoin - Intro to Political Economy, Lecture9
 
59:12
https://sites.duke.edu/intrope/ COURSE OVERVIEW: Introduction to Political Economy is a self-contained and nontechnical overview of the intellectual history of political economy, the logic of microeconomics, and the definitions used in macroeconomics. It introduces the notion of a political economy, emphasizing the moral and ethical problems that markets solve, and fail to solve. LECTURE OVERVIEW: 1. Venezuela as an example: a "shortage" of money? 2. Bitcoin: Is a global crypto-currency, has been around since January of 2009. It is not issued by any entity, but rather is peer-to-peer / decentralized. It trades over the internet, or “feature phones.” The protocol is open source. The participants are owners, buyers, and "miners," or people who transmit and check transactions. 3. The maximum number of Bitcoins will be about 21 million. A bitcoin is a unit of measurement, but the “unit” depends on solely on how people value it in transactions. No physical existence. 4. Five essential steps in a Bitcoin transaction: -- Step 1: owner of Bitcoins signs in, using public key (or Bitcoin Address) a bit like username) and a private key (a bit like password). -- Step 2: owner of Bitcoins sends X Bitcoins (highly divisible) to another Bitcoin Address. -- Step 3: This information is then broadcast by the software on the sender’s phone or PC, and received by all the (active) nodes in the network -- Step 4: All the active nodes add the (pending) transaction to the relevant (current) block. A block is like a ledger entry, divided into 10 minute intervals. All the transactions in one 10 minute interval are in the same block (blocks are disjoint: 10:10 to 10:20, 10:20 to 10:30, and so on…) -- Step 5: The block is run through a hash function by miners. This is a unique set of characters that contain all the information in the entire block, though knowing the hash won’t let you reproduce the block. Blocks are linked to previous blocks, creating a blockchain. The value of every account is evident on the blockchain.

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 squares in the Tangle represents transactions and each NEW transaction should reference transactions which have no other transactions referencing them. These non referenced transactions are called tips (tip 0 and tip 1). Each transaction consists of a bundle of transactions. An example of an IOTA transaction where 3 IOTA’s are transferred from Alice's address to Bob's address: https://www.mobilefish.com/download/iota/transactions_in_bundle_example1.txt A transaction consists of a bundle of transactions: currentIndex 0 refers to transaction 0, currentIndex 1 refers to transaction 1, etc.. All these transactions have the same bundle hash. All transactions in the same bundle should be treated as an atomic unit. It means that either all transactions of a bundle are confirmed, or none of them are confirmed. Every transaction in the bundle requires it own PoW, see the different nonces in the transactions. There can be 3 different types of transactions inside a bundle: - Output transactions Transactions where IOTA’s are send to one or multiple addresses. The IOTA light wallet can only send to one address. These transactions are easily recognised because the transaction value is always greater than 0 and the address does not belong the sender. - Input transactions There are two types of input transactions: * Input transactions where the value is negative. These are the transactions where the complete balance from that address is spent. * Input transactions where the value is greater than 0. These are the transactions where unspent/not used IOTA’s are send to a new change address in the senders wallet. - Meta transactions Zero value transactions are meta transactions. The signatureMessageFragment of these transactions could either hold a signature or a message fragment. Transaction examples: https://www.mobilefish.com/download/iota/transactions_in_bundle_example1.txt https://www.mobilefish.com/download/iota/transactions_in_bundle_example2.txt https://www.mobilefish.com/download/iota/transactions_in_bundle_example3.txt https://www.mobilefish.com/download/iota/transactions_in_bundle_example5.txt By increasing the security level you increase the key size, meaning you increase the private key size. Depending on the key size, this signature is fragmented and stored in 1, 2 or 3 transactions. Wallet 1, using security level 1, the signature is stored in 1 transaction: https://www.mobilefish.com/download/iota/transactions_in_bundle_security_level1.txt Wallet 2, using security level 2, the signature is fragmented and stored in 2 transactions: https://www.mobilefish.com/download/iota/transactions_in_bundle_security_level2.txt Wallet 3, using security level 3, the signature is fragmented and stored in 3 transactions: https://www.mobilefish.com/download/iota/transactions_in_bundle_security_level3.txt By increasing the security level you increase the signature size and thus the number of transactions needed to store the signature. IOTA signatures are larger than Bitcoin signatures due to IOTA's use of Winternitz one-time signatures to gain quantum resistance. Each single transaction inside a bundle consists of 2673 trytes and much of it is taken by the signatureMessageFragment which has a size of 2187 trytes (approx 82%). A single transaction inside a bundle requires 2673 trytes or ~1.55 kBytes. A bundle can have one transaction, for example when you attach an address to the Tangle. A bundle can have an X number of transactions. For example: Alice has a wallet (using security level 2) with address 0 to address 99 with each address having one IOTA. When Alice transfers her complete wallet balance to Bob, she creates a transaction bundle containing 201 transactions: 1 transaction to Bob, 100 transactions withdrawing 1 IOTA from each address and 100 meta transactions to store the second signature fragment. Each transaction inside the bundle requires a PoW. Let assume a PoW takes 20 seconds per transaction. Please note: This 20 sec is arbitrary chosen! In this example the total time to create the bundle, takes: 201 transactions x 20 sec / tx = 67 minutes. You can easily create a transaction bundle containing lots of transactions. However watch out for the Proof of Work.

Bitcoin Q&A: What happens to transaction fees when the block reward is zero?
 
04:28
Keywords/phrases: Based on the incentives in the network, what happens to fees when the reward for generating new blocks goes to zero? Will miners keep mining? Will the network fees be reasonable? This will gradually happen between now and 2141. Presumable the reliance on the block reward drops while the number of transactions rises. Fees will go up not because it's getting more and more expensive but because you have more and more transactions paying the same fee or less. We know this is going to happen just as we knew the Halvening was going to happen, because bitcoin is a deterministic currency. We don't have to wait for the spokesperson from the Federal Reserve to come out and tell us what our interest rate is. We're getting better at optimisation. If we introduce all the optimisation and scaling things, we can do more than Visa - cheaper. We will manage capacity in a way that isn't fatal, failing to scale (gracefully) for 25 years. This talk took place on September 13th 2016 at the Silicon Valley Bitcoin Meetup in Sunnyvale, California: https://www.meetup.com/Silicon-Valley-Bitcoin-Users/events/232546018/

Blockchain/Bitcoin for beginners 6: blocks and mining, content and creation of bitcoin blocks
 
46:48
In this video we introduce the basic concepts behind how new blocks are created in the Bitcoin blockchain. We start by taking another look at the blockchain.info website to see some sample blocks and then to a quick screencast explaining how new, unconfirmed transactions are collected by mining nodes and included in new transaction blocks, whose header needs to be hashed along with a random number to produce an output hash meeting a set requirement. I mention that the requirement is that the generated hash starts with a specified number of leading zeros...this is a slight (and very common) simplification, the reality is that the hash must be LESS than or equal to a specic 256 bit binary number. See here: https://youtu.be/4QxOUwG8a2Y I introduce the concepts of difficulty targets and validation of blocks

ep 14: OP_RETURN, proof of existence explained with demo
 
25:54
In this video, I'm taking a slight diversion to introduce an example of how the blockchain can be used for things other than transfer payments in the underlying transaction currency of that particular blockchain. We look at how by using the OP_RETURN transaction output type, we can include up to 40 bytes of freeform data, in the bitcoin transaction. Once the transaction gets mined into a block, like any other transaction, it becomes part of the unchangeable history of the blockchain. One use of this is known as "proof of existence" - if you can encode the hash of any document or file or digital asset in the blockchain, you can prove beyond reasonable doubt that the file existed in that particular exact state on or prior to the timestamp on that block. This has all sorts of potential applications.... I take you through a live example of an upload to this great website https://proofofexistence.com/ - they provide an interface to get your files hashed (locally) and arrange for that hash to be included in the OP_RETURN of a bitcoin transaction. You can then see the hash in that transaction on the following blockchain explorer (some explorers don't show transactions with OP_RETURN statements in there) https://www.blocktrail.com/BTC/tx/9fc5c20918333683fece4d82aabcc7c225a03606ef2bd8ed286b64bf65890cd7 Any questions please ask

What is a BitCoin? Explained - Tech Tips
 
17:40
what's bitcoin. Bitcoin is a worldwide cryptocurrency and digital payment system called the first decentralized digital currency, since the system works without a central repository or single administrator.It was invented by an unknown programmer, or a group of programmers, under the name Satoshi Nakamoto and released as open-source software in 2009. The system is peer-to-peer, and transactions take place between users directly, without an intermediary. These transactions are verified by network nodes and recorded in a public distributed ledger called a blockchain. Besides being created as a reward for mining, bitcoin can be exchanged for other currencies, products, and services. As of February 2015, over 100,000 merchants and vendors accepted bitcoin as payment. Bitcoin can also be held as an investment. According to research produced by Cambridge University in 2017, there are 2.9 to 5.8 million unique users using a cryptocurrency wallet, most of them using bitcoin.On 1 August 2017 bitcoin split into two derivative digital currencies, the classic bitcoin (BTC) and the Bitcoin Cash (BCH). Terminology. The word bitcoin occurred in the white paper that defined bitcoin published on 31 October 2008. It is a compound of the words bit and coin.The white paper frequently uses the shorter coin. There is no uniform convention for bitcoin capitalization. Some sources use Bitcoin, capitalized, to refer to the technology and network and bitcoin, lowercase, to refer to the unit of account. The Wall Street Journal. The Chronicle of Higher Education, and the Oxford English Dictionary advocate use of lowercase bitcoin in all cases, a convention which this article follows. Units The unit of account of the bitcoin system is bitcoin. As of 2014, symbols used to represent bitcoin are BTC,[note 1] XBT,[note 2] and ₿ (U+20BF, BitcoinSign.svg).[note 3:2 Small amounts of bitcoin used as alternative units are millibitcoin (mBTC),[1] microbitcoin (µBTC, sometimes referred to as bit), and satoshi. Named in homage to bitcoin's creator, a satoshi is the smallest amount within bitcoin representing 0.00000001 bitcoin, one hundred millionth of a bitcoin.[9] A millibitcoin equals to 0.001 bitcoin, one thousandth of a bitcoin. One microbitcoin equals to 0.000001 bitcoin, one millionth of a bitcoin. bitcoin Design. Blockchain[edit] For a broader coverage related to this topic, see Blockchain. Number of unspent transaction outputs The blockchain is a public ledger that records bitcoin transactions. A novel solution accomplishes this without any trusted central authority: the maintenance of the blockchain is performed by a network of communicating nodes running bitcoin software.Transactions of the form payer X sends Y bitcoins to payee Z are broadcast to this network using readily available software applications.Network nodes can validate transactions, add them to their copy of the ledger, and then broadcast these ledger additions to other nodes. The blockchain is a distributed database – to achieve independent verification of the chain of ownership of any and every bitcoin amount, each network node stores its own copy of the blockchain. Approximately six times per hour, a new group of accepted transactions, a block, is created, added to the blockchain, and quickly published to all nodes. Transactions. Transaction fees. Paying a transaction fee is optional. Miners can choose which transactions to process and prioritize those that pay higher fees. Fees are based on the storage size of the transaction generated, which in turn is dependent on the number of inputs used to create the transaction. Furthermore, priority is given to older unspent inputs. Mining Semi-log plot of relative mining difficulty.[note 4 Mining is a record-keeping service.[note 5] Miners keep the blockchain consistent, complete, and unalterable by repeatedly verifying and collecting newly broadcast transactions into a new group of transactions called a block Each block contains a cryptographic hash of the previous block using the SHA-256 hashing algorithm,:ch. 7 which links it to the previous block, thus giving the blockchain its name.

I.R.S. Bitcoin Tracing Tools; Track & Identify Transactions via Chainalysis

I.R.S. Bitcoin Tracing Tools; Track & Identify Transactions via Chainalysis: https://steemit.com/@garypalmerjr As we mentioned in yesterdays video, #Bitcoin is not 100% anonymous; is only pseudo-anonymous, and while some of your privacy may be leaking online, analytics companies like "#Chainalysis" are sifting-up the details and placing tags on a whopping 25%-plus, of all Bitcoin addresses! And now, we find out that U.S. #InternalRevenueService (yes, the beloved #IRS) is using this #BitcoinTracing software (from the startup "Chainalysis") to monitor as many Bitcoin transaction as possible. So, if you pay your taxes and have no secretes, then do you have anything to worry about? Should we be upset that exchanges like #Coinbase are allegedly storing wallets in such a way that an analytics company like Chainalysis or #BitSeer can identify individual users? And what does it mean that the owners of Coinbase have an ownership stake in the startup Chainalysis? === Show Links === ► http://coinmarketcap.com/ ► https://www.coindesk.com/irs-using-bitcoin-tracking-software-since-2015/ ► http://fortune.com/2017/08/22/irs-tax-cheats-bitcoin-chainalysis/ ► https://www.reddit.com/r/Bitcoin/comments/6vbhcv/good_morning/ ► https://cointelegraph.com/news/hodlers-beware-hackers-persuade-phone-companies-to-hand-over-numbers ► https://cointelegraph.com/news/each-bitcoin-could-be-worth-619047-in-10-years-forbes-contributor === HOW TO HELP ♥ MINTING COINS™=== 1) WATCH, + Subscribe, Like, & Comment :) 2) DONATE Cryptocurrency, to the addresses below. 3) FOLLOW-us on SteemIt: https://steemit.com/@garypalmerjr/ 4) JOIN us at: https://mintingcoins.com/ === DONATIONS Accepted === ✯ Donate BTC-Bitcoin ♥ 1G5QaqZH6WQ5wcFb6TGbHoT7Ugct6TYnML ✯ Donate ETH-Ether ✯ 0x2184b97649a1689E7F92b11f217AF8ae39f701Aa ...or use our ENS name: mintingcoins.eth ✯ Donate DASH ✯ Xmi5w4F26VPt2C5pSJQahe8969V43zrP2J ✯ Donate LTC-Litecoin ✯ MTPicHRLbBwmqcSEAyhm9qXox2GdAb6iBb ✯ Donate ZEC-Zcash ✯ t1VqC9NL5o3DkNBzKB4fPvtDsdGQ1h2F2nR ✯ Donate BCH/BCC-Bitcoin Cash ✯ 1FXxpWiHh9XoCNrRpb8ii61aecYDDCp2do ✯ Donate XMR-Monero ✯ 49E4qvpriNgJ8C1wD9iSDDcSiSqXFwUUdP7XRnhw7CbfT5mLeGk2M5n6pZtu5P6sk7KficCFCpFUdSpfBqguP1HR6iahc6u === FOLLOW, Like, & Subscribe === ♥ Follow us on SteemIt: https://steemit.com/@garypalmerjr ➨ Follow us on Twitter: https://twitter.com/MintingCoins/ ➨ Like us on Facebook: https://www.facebook.com/MintingCoins/ ➨ Follow us on Google+: https://plus.google.com/+MintingCoins E-mail us any screenshots, footage, or ideas ..for future episodes, to: MintingCoins 23 @ gmail .com === Approved Products === MINTING COINS™ T-shirt & Accessories! ♥ https://MintingCoins.spreadshirt.com/ Join COINBASE: ♥ https://www.coinbase.com/join/528bf7b561411909040001fa TREZOR Wallet (Cryptocurrency/Bitcoin Hardware-Wallet) ► Shop: https://mintingcoins.com/shop ► eBay: https://goo.gl/sSib2w Bitmain ANTMINER'S ► Shop: https://mintingcoins.com/shop ► eBay, S9 & S7: https://goo.gl/yRdPsG === ABOUT Minting Coins™ === It's time to join the Blockchain & Cryptocurrency Revolution.

Bitcoin Scalability SOLVED - Bitcoin to become "streaming money" and radically transform commerce
 
09:18
Bitcoin Scalability SOLVED - Bitcoin to become "streaming money" and radically transform commerce. - Billions of transactions per second - 0 fees - No Banks - Just Hodl The Bitcoin Lightning Network is essentially a decentralized system where users can set up trustless micropayment channels to conduct one or multiple payment transactions off-blockchain. These channels reside outside the Bitcoin blockchain. However, once the payment channel is closed, the transactions that occurred between the channels are then broadcast, as a single transaction, to the main blockchain network. Thus, no matter the number of micro-transactions conducted, the blockchain is accessed only twice, when the channel is opened and when the channel is closed. Obviously, this approach would significantly reduce the load on the blockchain. Presently, three teams are independently working on the LN implementation: ACINQ, Blockstream, and Lightning Labs. In early December 2017, they announced that their respective systems had completed payment tests on the main Bitcoin network. Moreover, these tests achieved interoperability across all three implantations. Right now, to educate potential LN users, the website https://htlc.me/ allows you try a testnet Bitcoin LN transaction.

What is Bitcoin (Part 3) - the Blockchain

Watch, like, subscribe and tell us your opinion in the comments! If you would like to support us either check out our Patreon: https://www.patreon.com/theinvisiblefootofgovernment or donate some bitcoins to the wallet address 1A6oNTWReRy2reBwaHPLJ8147XTU2vGikm and spread the word about us :) This video series is based on part 3 of this paper by Rasheed Sabar https://www.ellington.com/content/uploads/2017/09/What-Are-Cryptocurrencies_Sabar.pdf Narration --------------------------------------------------------------------------------- Definitely watch Parts 1 and 2 first! There are a couple of reasons why proof-of-work is a really cool solution to secure the ledger. First of all it is a secure way to pick a random validator without a centralized entity (this might not be such an obvious problem, but ask yourself how can you pick someone randomly in a decentralized network, that mechanism could easily be a point of failure, for someone to come in, mess with it and make it select them) secondly it’s a way to check that the validator participated in the selection process and the more validators participate in guessing the number the harder it is for an attacker to overwhelm the network and mess with the ledger, because they’re up against the combined computing power of all the validators. Think of it like this, all the validators are working together to find that number. A malicious intruder who would want to make sure that he was selected would have to guess the number faster than the whole network of validators together. Cool! No we arrived pretty much at how bitcoin works. Bitcoin’s validators are called “miners” (yeah, maybe not such a good choice) and the community ledger is called the “public blockchain”. Block chain, Block chain, buzzword alarm!! Yeah I saved this for the end. What is a blockchain? It’s bitcoins decentralized ledger and it has one more feature that I didn’t mention yet. A blockchain is a specific way to store data in which each new data element embeds a condensed copy of the prior element, all the way back to the first element. (These elements are called blocks and they are basically just a set of new transactions that we want to append to our blockchain ledger in the case of bitcoin). This structure makes it hard to alter past data because now the condensed copy in the next block wouldn’t match anymore. So someone trying to alter past data would have to literally alter every following block, since the one they altered, as well ... or it would be obvious that something was altered. So that’s bitcoin and the blockchain. Here are a couple more things that are worth mentioning. - The bitcoin ledger can be checked by anyone any time - It has privacy through aliases (kind of like bank account numbers that are not associated with a real name) - It’s tamper resistant without any central authority Today, Bitcoins validators are rewarded with new bitcoins that are programmed to be created at every block, so every 10 minutes, and not yet so much transaction fees. The number of new coins created to compensate the validators is programmed to decrease over time, and we can calculate that the total number of bitcoins will be 21 million in the year 2040 (around 16 and a half million bitcoins already exist today in 2017). Different from a central bank which creates new money when they feel like it, they claim to follow certain rules, but who knows … in Bitcoin the increase in coins is pre-programmed and transparent and will stop in 2040. Lastly, why is Bitcoin called a “crypto” currency? That’s because it uses cryptography in three places: in proof-of-work puzzles for anti-tampering, in digital signatures for anti-forgery, and in hash functions (those are the condensed versions of the previous block that we put into new blocks). Of course this was not enough to answer all of your questions about bitcoin. Probably you actually have more questions now! No worries, we are going to be posting more videos about the topic, but definitely post your questions in the comments!
Blockchain tutorial 24: Blockchain and miners
 
07:34
This is part 24 of the Blockchain tutorial explaining what a Blockchain is and what miners are. This tutorial explains the following: - what the blocks are in the blockchain - what data does a block contains - what a block number and block height is - what a genesis block is - what a main chain, side fork or orphaned forks are - what miners are and their purpose - what a coinbase transaction is and how Bitcoins are created - there will be maximum 21 million Bitcoins - what a block reward is - what block reward halving is - what a hash puzzle is 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.

You can obtain one from an online based service such as Coinbase or Blockchain.info. These are two of the most used bitcoin wallet and come with an online and a mobile version. Having said that, the safest way to store your bitcoins would be offline. For that, you could use a so-called “cold wallet” such as Trezor.

Bitcoin Mining we love bitcoinMining bitcoins can be quite complex and is usually not recommended for beginners. The process entails the use of sophisticated machines that are expensive and consume quite a lot of electricity to solve mathematical algorithms in exchange for bitcoins. Bitcoin miners enable bitcoin transactions by sharing their processing power. In exchange for enabling the bitcoin network to function, they are rewarding with new bitcoins. This is what “mining” refers to. Having said that, it is no longer considered lucrative for individuals to mine at home using mining equipment and the shift is being made towards more large-scale operations. If you do want to engage in bitcoin mining and are willing to invest in expensive mining hardware, it is strongly advisable to join a mining pool. In a mining pool, miners pool their resources together and share their hashing power with the aim of solving a block and dividing the reward equally, depending on the number of shares contributed by each person. It is an effective way to motivate small-scale miners to continue their involvement in mining activities. Some popular mining pools are: Antpool BTCC SlushPool Bitcoin Cloud Mining Alternatively, you could engage in bitcoin cloud mining. Bitcoin cloud mining is the process of mining bitcoins using a remote datacenter with shared processing power. Cloud mining is beneficial to individuals as it allows them to carry out their mining activities without having to manage the mining hardware. It enables you to earn bitcoins without mining software, mining hardware, bandwidth, electricity or other offline issues. However, there is a cost associated with cloud mining as a service and this will have an effect on your bottom line. The most reputable cloud mining company is Genesis Mining. I personally have a small bitcoin mining contract running with them. Having said that, the time it will take you to break even on bitcoin cloud mining can easily take well over a year and that is assuming the price of bitcoin doesn’t drop. If you want to play your part in the bitcoin network and want to mine at a low cost, then cloud mining is a good option. If you are looking for a lucrative investment, however, you are much better off just buying the cryptocurrency itself or engaging in peer-to-peer bitcoin lending.

The Lightning Network - the Bitcoin Scaling Debate!
 
04:27
LOOKS LIKE I MIXED UP THE LIGHTNING NETWORK AND SIDE CHAINS A BIT! THOSE ARE TWO SLIGHTLY DIFFERENT TECHNOLOGIES ... SORRY!! Patreon: https://www.patreon.com/theinvisiblefootofgovernment bitcoin wallet: 1A6oNTWReRy2reBwaHPLJ8147XTU2vGikm We thank you for all of your support so so much :) Watch, like, subscribe and tell us your opinion in the comments! Here are some good links if you want to read more about this Timeline: https://hackernoon.com/the-great-bitcoin-scaling-debate-a-timeline-6108081dbada About Segwit: https://medium.com/@brenmcma/understanding-segwit-and-the-bitcoin-scaling-debate-c9f7170e9e79 Narration --------------------------------------------------------------------------------- The Lightning Network Definitely watch the video “what is Bitcoin?” first, cause it’s going to get a bit technical. The way bitcoin is set up only about 3 transactions per second are possible. Compare that to a couple of thousand per second on conventional payment networks like VISA. So by 2015 the bitcoin network was already starting to get congested. More and more people we sending bitcoin transactions and it was reaching the limit of it’s capacity. So the transaction fees started to increase as people were trying to pay to get priority over other transactions and have their transactions processed quickly by the validators. It was pretty obvious that something needed to be done to increase the number of transactions that were possible per second. Two solutions were proposed and bitcoiners split up into two camps each supporting one of the solutions. The first solution was an obvious fix. The reason the number of transactions is limited is that blocks are limited to only 1 MB. Blocks are the groups of transactions that are appended every 10 minutes. So basically that means that the ledger that records the transactions can only be appended by 1MB worth of transactions every 10 minutes. Now one camp says, we need a fast solution or people are going to stop using bitcoin. The most obvious solution is to increase the block size. Just change it from 1MB to 2 or 8 or 32. But the other camp think that that’s a bad idea because on one hand it would be an upgrade where people on the network who hadn’t upgraded wouldn’t be able to use bitcoin anymore. Usually the developers had done their best to make the updates backwards compatible with the older software versions so that people who didn’t upgrade wouldn’t get kicked off the network. But more importantly they are worried that that could make the bitcoin network less distributed and more centralized. How so? So remember all the features that needed to be added in our thought experiment in the video “what is Bitcoin?” In order to distribute the ledger among the validators and then keep the copies synchronized and avoid tampering? That ends up being a pretty massive infrastructure. But it’s important that as many people as possible participate in maintaining the network, not just as transaction validators but also as what are called nodes. Nodes store an updated version of the ledger without participating in the validating. Transaction validators contribute processing power and memory, nodes only contribute memory, but they play an important role in keeping the network distributed, keeping it from centralizing. Whoever participates needs to have a copy of the entire blockchain on their computer. So the more transactions happen per block, the faster the blockchain will grow and the harder it will be to maintain by regular people and the smaller the network will be and the more vulnerable the network will be. Some counter that computers are getting faster and memory is getting cheaper faster than the blockchain would increase so it doesn’t matter, but let’s move on. So what is the other camp proposing? The lightning network. It’s basically a system where the bulk of small transactions happen in side chains instead of the bitcoin block chain. Think of it like this. Alice and Bob do a bunch of transactions. Bob owns a supermarket and Alice does her grocery shopping there. So they record their transactions and every once in a while update the bitcoin blockchain with 1 consolidated transaction. The other cool thing is that the side chains would be run by nodes, which would be able to charge a small transaction fee too. So that would even encourage a larger decentralization of the network, because more people would have an incentive to run nodes and not just the validators would be profiting from securing the network. So but for that to work that camp needed to pass a fix called Segwit to the software that corrected a bug that was allowing people to change their transaction IDs in the middle of a transaction. It was a huge debate but eventually the bug fix was accepted. Now we should see the lightning network rolling out. But so far unfortunately there isn’t much. That’s maybe because it’s ...

There are several types of wallets that provide different ways to store and access your digital currency. Wallets can be broken down into three distinct categories – software, hardware, and paper. Software wallets can be a desktop, mobile or online. Desktop: wallets are downloaded and installed on a PC or laptop. They are only accessible from the single computer in which they are downloaded. Desktop wallets offer one of the highest levels of security however if your computer is hacked or gets a virus there is the possibility that you may lose all your funds. Online: wallets run on the cloud and are accessible from any computing device in any location. While they are more convenient to access, online wallets store your private keys online and are controlled by a third party which makes them more vulnerable to hacking attacks and theft. Mobile: wallets run on an app on your phone and are useful because they can be used anywhere including retail stores. Mobile wallets are usually much smaller and simpler than desktop wallets because of the limited space available on a mobile. Hardware: wallets differ from software wallets in that they store a user’s private keys on a hardware device like a USB. Although hardware wallets make transactions online, they are stored offline which delivers increased security. Hardware wallets can be compatible with several web interfaces and can support different currencies; it just depends on which one you decide to use. What’s more, making a transaction is easy. Users simply plug in their device to any internet enabled computer or device, enter a pin, send currency and confirm. Hardware wallets make it possible to easily transact while also keeping your money offline and away from danger. Paper: wallets are easy to use and provide a very high level of security. While the term paper wallet can simply refer to a physical copy or printout of your public and private keys, it can also refer to a piece of software that is used to securely generate a pair of keys which are then printed. Using a paper wallet is relatively straightforward. Transferring Bitcoin or any other currency to your paper wallet is accomplished by the transfer of funds from your software wallet to the public address shown on your paper wallet. Alternatively, if you want to withdraw or spend currency, all you need to do is transfer funds from your paper wallet to your software wallet. This process, often referred to as ‘sweeping,’ can either be done manually by entering your private keys or by scanning the QR code on the paper wallet.

Bitcoin Transaction (VJ Edition)
 
02:40
Bitcoin Transaction (VJ Edition) ------------------------------------------------------------------------------------ Bitcoin is a digital money, meaning it's Digital, simple. It is based on 0 and 1s, as they say. A more efficient way of showing 0 and 1s is by using their hexadecimal representation a.k.a base 16. All historical data of all Bitcoin transactions ever happened are stored in a big database called "Blockchain", and that is because these hexadecimal numbers are grouped together in batches called "block" and appended to the previous data on the database with a cryptographic method to prove the order and sanity, so basically a chain, a Blockchain. Everyone running a Bitcoin full node, have a fully secure copy of this database. It’s just like torrent, when you download a linux image, you actually connect to some other computers and download the file from them, a peer to peer connection. So when you run Bitcoin software on your computer, It starts downloading that database and verify all the blocks, one by one, to make sure it’s a legit copy that everyone else have. That is the basics of Bitcoin. Transaction hash: 7f2875779f2429ee76e50857c6407e56ecc5ba7b0c9cfb102a477e50072233fa https://api.blockcypher.com/v1/btc/ma...

Blockchain 101 by HBUS | Ep.15 How do Bitcoin transactions work?
 
01:06
Bitcoin transaction fees give Bitcoin miners an incentive to include transactions into their blocks and provide sufficient hashing power, securing the Bitcoin network. Some also call it “miner fees”. When making a transaction over the Bitcoin network, one usually pays for miners to facilitate the transaction. The fee tends to be around 0.0001-0.0015 Bitcoin. Block sizes are limited and can only support limited number of transactions. Therefore, miners will prioritize transactions that pay higher fees. A higher fee means the transaction can be processed sooner. This raises the threshold of making Bitcoin transactions and also effectively protects the blockchain from spams while ensuring miners still have the incentive to maintain the Bitcoin network even after all the Bitcoins are mined.
