BTC: How to Avoid High Fees & Tx Times

I also want to go over the scary concept that is unconfirmed transactions. If you’ve ever sent bitcoin to another wallet, you’ve probably had the delightful experience of anxiously waiting and constantly refreshing your screen until you see that your transaction has indeed been confirmed by the network. If you’ve ever wondered if there’s anything you can do besides pay a hefty transaction fee to ensure it goes through quickly, I have good news for you. The answer is to check the status of the Mempool. There are many websites that are happy to fill you in on this information. Mempool stands for Memory pool and it refers to the holding area for pending transactions. When you first send out your transaction it is sent into the mempool where it waits to be selected by a miner to include it in the next block. The size of the mempool lets you know generally how many blocks will need to be mined before your transaction is confirmed. If the mempool size is 3MB, you’ll need to wait for three blocks to be mined before your transaction is confirmed. It’s possible that the mempool could become too large with pending transactions; this could cause the nodes to crash. To prevent this from happening the nodes will introduce a minimum fee. If your transaction is waiting in this mempool and the fee paid does not meet this minimum then your transaction will be dropped from the mempool and the balance will be sent back to your wallet. So when the blockchain gets flooded with transactions this can explain at least in part why the fees increase and why transactions take a long time to go through. So if you have time to spare, you can keep an eye on the size of the mempool to see when the number of waiting transactions is down, that’s when your transaction will go through quickly and with much cheaper fees. One thing to keep in mind here about the transaction fees. If you try to send your bitcoin without paying any transaction fee or you pay a very very small transaction fee compared to the average being paid, most likely your transaction will be left unconfirmed for many days, weeks or it may never be confirmed. An unconfirmed transaction means the amount of Bitcoin you’ve tried to send is withdrawn from your balance will not be sent to the destination and your Bitcoin is stuck and will not be returned to your wallet. Your best chance at this point is that there exists a miner who will process your transaction knowing that you did not provide them with a fee payment. Most wallets will calculate a proper transaction fee to ensure that this will not happen. Some will even give you some fee options to choose from depending on how quickly you’d like your transaction to be confirmed. The busier the network, the more transactions that are flooding the network, the higher your transaction fee will need to be to ensure that your transaction doesn’t get tossed aside and stuck in limbo. If you’ve ever been curious about how the Bitcoin network is doing, what kind of profit miners can make, which mining pools are dominating the network, you can check out the many Bitcoin block explorer websites. These are good for finding out all sorts of information about the state of the Bitcoin network. Things like the most recent blocks mined, the number of transactions being included in those blocks, transaction fees, and unconfirmed transactions. This tool isn’t exclusive to Bitcoin either. If you’re interested in learning more about Ethereum, Stellar, EOS or other coins with their respective blockchains you can most likely find links to these options with a simple DuckDuckGo search.

The Bitcoin and Blockchain Technology Explained
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?

Blockchain tutorial 27: Bitcoin raw transaction and transaction id
This is part 27 of the Blockchain tutorial. This tutorial explains: - What Bitcoin raw transaction is. - Shows an example of a raw transaction using the very first transaction on the Genesis block. - What the difference is between big endian and little endian. - What a satoshi is. - What a Bitcoin transaction id or hash is and what its purpose is. - How to calculate the transaction id. 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.

Bitcoin Q&A: Enterprise "blockchain" gentrification?
Will mainstream adoption affect the culture of crypto? Are enterprise "blockchain" projects signs of gentrification? Banks will train the developers for us. They can't ignore Bitcoin forever. Why is there so much development and marketing around private blockchains? Not all blockchains are created equal. Immutability is not a characteristic of all blockchains. Is proof-of-authority or committee-driven dynamics (i.e. standards war) in federated systems interesting? These questions are from the Polish Bitcoin Congress (Polski Kongres Bitcoin) Warsaw, Poland, and the November Patreon session, which took place on May 12th and November 17th, 2018, respectively.

Testnet & Faucets | Mainnet | Bitcoin - Etherum - Blockchain | Hindi
Bitcoin Testnet Sandbox and Faucet brings all the coins to developers and interesting insights of the Testnet Blockchain. The testnet is an alternative Bitcoin block chain, to be used for testing. Testnet coins are separate and distinct from actual bitcoins, and are never supposed to have any value. This allows application developers or bitcoin testers to experiment, without having to use real bitcoins or worrying about breaking the main bitcoin chain. Run bitcoin or bitcoind with the -testnet flag to use the testnet (or put testnet=1 in the bitcoin.conf file). There have been three generations of testnet. Testnet2 was just the first testnet reset with a different genesis block, because people were starting to trade testnet coins for real money. Testnet3 is the current test network. It was introduced with the 0.7 release, introduced a third genesis block, a new rule to avoid the "difficulty was too high, is now too low, and transactions take too long to verify" problem, and contains blocks with edge-case transactions designed to test implementation compatibility. On the December 21 of 2015 SegNet was deployed, to test the Wuille's Segregated Witness proposal. www.nodearts.com

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

What is The History of Bitcoin: Super Easy Explanation
What is The History of Bitcoin: Super Easy Explanation - https://blockgeeks.com/ We’ll start at the very beginning by understanding the history of blockchain. The very first blockchain in the world was Bitcoin. An anonymous person or group known as Satoshi Nakamoto published a document in an online cryptography forum in November 2008 and revealed the first details of how it would work, describing it as a “peer-to-peer electronic cash system”. The whitepaper is available today at bitcoin.org/bitcoin.pdf. It allows any 2 people to pseudonymously send money to each other no matter where they are in the world. It is a borderless currency. The main benefit of Bitcoin is that it does not require any centralized authority or institution to operate. This is in contrast to today’s centralized financial systems that depend on the existence of a central bank or government to mint money. If for any reason the central authority were to shutdown, the money would become worthless. In a decentralized system like Bitcoin, there is no central authority and the system can continue to operate as long as there are members in its peer-to-peer network. The goal of the whitepaper was to describe how the different parts of the Bitcoin protocol would operate and be kept secure. A new type of database, called a blockchain, would keep track of a single history of all Bitcoin transactions and it would be maintained by everyone in the network. The database would be publicly available for anyone to view and inspect, and anyone can download a copy of the same database. This provides data redundancy and makes sure the data is never lost, but also provides a way for anyone to verify the transactions in the database themselves. A block in the database just stores a sequence of transactions, and a sequence of blocks is called a blockchain. Each block is identified by an incrementing number and a unique Sha-256 hash. The hash for a block is calculated using the transactions inside it, as well as the previous block’s hash, which forms a chain of hashes. The data in the blocks is secured using a cryptographic algorithm called proof-of-work, which also keeps all members of the network and the database in sync to prevent double-spending. In this context, preventing double-spending means preventing anyone from spending money they dont have. Proof-of-work is used to generate new blocks for the database, also known as mining, and the reward for mining a new block is given to the miner by creating new Bitcoins in the system. This is the only way new Bitcoins can be created. Anyone on the network can be a miner and a new block is mined roughly every 10 minutes, which includes the latest set of verified transactions. The first release for Bitcoin was version 0.1 written in C++ by Satoshi and published on SourceForge in January 2009 under the open-source MIT license. Anyone could download the source code and run it to join the network, also known as becoming a node in the network. This is the original version 0.1 source code written by Satoshi. We can see the hard-coded genesis block, which is the very first block in the chain. The hash for the block can be verified by using any Bitcoin blockchain explorer. Let’s copy and paste this hash into the blockchain explorer available at blockchain.info. We can see that this hash is for block number 0, and that it has only one transaction in it which is the mining reward, and the reward amount of 50 Bitcoin was given to this Bitcoin address. We can also see this 50 Bitcoin reward for the genesis block in the original source code. The genesis block is a special case needed to start the blockchain and is the only block that is hard-coded, whereas every subsequent block is calculated using proof-of-work. Satoshi’s motivation for creating Bitcoin is revealed in the piece of data he included in the genesis block: a newspaper headline from The Times that read ‘Chancellor on brink of second bailout for banks’. The date of the newspaper is proof that the genesis block was created on or after Jan 3 2009. Satoshi developed the source code mostly himself up until mid-2010, when he handed it off to the open-source community. It is now maintained under the project called Bitcoin Core. The software is currently at version 0.15.1 and is available for download at bitcoin.org. This is still the most popular Bitcoin client, and its estimated that there are over 10 thousand nodes running the Bitcoin network today using various clients. Satoshi disappeared from public view in late 2010, his identity still unknown to this day. The only way someone could prove that they are Satoshi is by using the same encryption keys used when posting the original whitepaper in the online cryptography forum.

What is a Bitcoin Node? - Step by Step Explanation
What is A Bitcoin Node. Step by Step Explanation https://blockgeeks.com/ The bitcoin network consists of a network of nodes, which are just computers or servers running the Bitcoin software. The code ensures the nodes can find and establish connection with other nodes and hence form a network that is used by the various nodes to transfer information, like transactions, blocks and other data. Through this web of interconnecting nodes, bitcoin can send digital cash securely through the network. The underlying bitcoin code implements the bitcoin protocol. So how does a new node join the bitcoin network? First it must discover at least one peer to connect to and then it can get a list of other peers from that initial peer. There are a few methods a node can use to connect to its first peer. The bitcoin client contains a hardcoded list of well known DNS servers which can return a list of ip addresses of bitcoin nodes. Alternatively, the bitcoin client can be given a static ip address of a peer if one is known. You can pass this ip address as a parameter when starting the bitcoin client software through the command line. It’s important to note that bitcoin’s network topology is not geographically defined, so the physical location of the nodes in relation to one another is irrelevant.This means a node can find and connect to any other node regardless of where it is in the world. Once a node has the ip address of a peer, it then goes through an initial handshake to establish a connection with a remote node. First the local node will send a version message to the peer which contains some basic information about itself. This will always be the first message sent by any peer to another peer. The remote peer receiving the message will examine if the sender’s version is compatible with its own version. If it is, it will acknowledge the version message and establish a connection by sending a “version acknowledgment” message, which consists only of a message header with the command string “verack”. Once a node establishes connections with one or more peers, it will exchange some information with these peers. For example, nodes can exchange ip addr of their connected peers, so each node can maintain a list of peers that it can use to re-establish connection in the future since nodes can leave and join the network at anytime. A Node can also ask its peers what the length of their local copy of the blockchain is. It can then determine if it’s own copy of the blockchain is missing any blocks, and if so, can ask its peers to send the missing blocks. Of course it can also send blocks to other nodes who do not have as much data as itself. Let’s take a closer look at the various nodes in the network. Although all the nodes participate in the network, they have different roles depending on the functionalities they want to support. There are 4 major functions: routing, storage, mining and wallet services. The bitcoin core client implementation in c++ has all four of these functionalities. Routing is the bare minimum functionality a node must support in order to participate in the bitcoin network. It contains the functionality to discover and connect to other peers in the network and it also validates and propagates transactions and blocks through the network. It serves the purpose of keeping the network connection alive and passing information through the network. A node is called a full blockchain node if it stores a local copy of the entire blockchain database. A full node can autonomously and authoritatively verify any transactions without any external references. With a full node you get complete independence and freedom from central authority at the cost of hardware storage space. A mining node serve the special purpose of creating a new block to add to the blockchain. Mining nodes runs special mining software in order to solve a cryptographic puzzle to win mining rewards. They serve the purpose of adding new transactions into the blockchain. To learn more visit us at blockgeeks.com

Typically, these transactions occur in the production environment called the Mainnet but there’s also a few test networks available for us to use. Test networks are useful when you want to use Ethereum without having to pay real money. Some of the popular test nets today are Ropsten, Rinkeby and Kovan. Properly functioning test environments are a critical part of the DAPP development process. Ropsten, which is the main public network and uses proof of work has become prone to spammy transactions and slowness. In response to this, two separate community efforts led to the creation of new test nets, Rinkeby and Kovan. These networks require authenticating using your GitHub account and the transactions are validated using proof of authority meaning there are a small set of validators. Let’s try to send a transaction over the Rinkeby test net. We’ll use a Chrome plugin called MetaMask to connect to the network and make transactions. I highly recommend getting MetaMask since it makes interacting with the Ethereum blockchain extremely easy. First, we’ll change the network to Rinkeby to make sure we’re using test ether and not real ether. Let’s create two test accounts and label them. To get test ether into these accounts, we need to use a tool called a Faucet which is just a website where you enter your address and it sends you some test ether. Let’s copy the address for one of our accounts. When we click the buy button, we get redirected to the Faucet. Since we’re connected to Rinkeby, we need to use our GitHub credentials to get the test ether. To do this, go to gist.github.com, create a new Gist with a single line that contains the address you just copied and publish it. You then copy the Gist URL and paste it into the Faucet. In a few short moments, we can see that we have updated the balance in our account. The reason the balance took a few seconds to update is because we need to wait for the transaction to get mined on the Rinkeby network. Now, let’s move this test ether between our accounts. First, let’s copy the address of our receiving account. Then, we click the send button, paste the address, as well as the amount and hit submit. Once we submit the transaction, we’re provided a transaction hash which we can use to reference this transaction. If we use an Ethereum blockchain explorer like Etherscan, we can get more details about this transaction. Since we made the transaction on the Rinkeby network, we have to use rinkeby.etherscan.io and we can see that the transaction is still waiting to be mined. Once it is successfully mined, we’ll see a block number assigned to the transaction. We can then verify the updated account balances using MetaMask.

And also allow for alt coins and Bitcoin to scale- Remember Lightning Network? They could also one day allow for cryptos to interact with each other, thus opening the door for so many possibilities. Understanding Blockstream: https://thecontrol.co/understanding-blockstream-25af2b6f0084 So Blockstream funds the development of Bitcoin Core, which is the main Bitcoin network client software. Blockstream is a blockchain technology company that also boasts itself as being the originator of side chains. Whether or not that’s true, they were at least one of the first and still a major player that is pursuing this big idea. https://blog.blockchain.com/tag/blockstream/ Let’s break down what a sidechain is. In laymen’s terms, sidechains run parallel to a main blockchain, like bitcoin’s blockchain for example. They use a two-way peg, meaning you can move your bitcoin from the main bitcoin blockchain, to the sidechain, and then back again. This is done by essentially locking away your bitcoin from the main blockchain while it is in use on the sidechain, and they are then released once you prove they are no longer being used on the sidechain. The first side chain is called Elements Alpha. It’s a tesnet where developers can utilize the open source code to contribute to the project and discover ways to improve the bitcoin blockchain. Other projects for side chain implementations include the likes of Rootstock. The developers at Rootstock, or RSK have announced at consensus 2017 the release of Ginger, which is their open sourced testnet. Ginger is aimed at providing more functionality to the Bitcoin Network like smart contracts, increased scalability and a new revenue stream for miners. http://media.rsk.co/rsk-announces-the-global-release-of-ginger-the-open-source-testnet/ https://www.cryptocompare.com/coins/guides/what-is-rootstock/ As always in crypto land, it’s not always sunshine and roses, there are still some kinks to work out with side chains until they can be considered ideal. One of the arguable weak points of sidechains is the fact that federations are a select few who ultimately call the shots and determine if/when the coins you use between the main blockchain and the sidechain are locked up and released. This is a centralization of the whole system, and whoever is behind the sidechain will determine who is included in its federation. Trusting a dozen or so individuals to authorize all transactions can be seen as a major security flaw. One other weak point is the fact that sidechains will need it’s own miners. This could pose a problem when considering that these miners will need to be monetarily incentivized. One way to fix this is by implementing merge mining. T his is the process of allowing two different crypto currencies based on the same algorithm to be mined simultaneously. It allows low hash powered crypto currencies to increase the hashing power behind their network by bootstrapping onto more popular crypto currencies. https://www.cryptocompare.com/mining/guides/what-is-merged-mining-bitcoin-namecoin-litecoin-dogecoin/ I’m sure that there are Bitcoin maximalists out there who see this development of side chains for Bitcoin as a nail in the coffin for Ethereum. Because sidechains have the potential to provide Bitcoin with the ability to integrate smart contracts, this does seem to take an edge away from Ethereum in terms of services provided. However, I will always believe in the robust development team behind Ethereum and their ability to work together to constantly produce innovative new projects. So don’t say goodnight to Ethereum. Instead, I’d like you to consider how side chains can open the door for different cryptocurrencies to work together and take advantage of their strengths.

What is Bitcoin mining? - GMO INTERNET
https://mining.gmo.jp/ Bitcon is built on blockchain technology that regularly adds all transaction records to blockchain, which is a chain of blocks saved on the network. If transaction data of Bitcoin, which is exchanged all over the world, is transmitted to the network, miners worldwide will compete to generate a block of transaction data of a given time period. The exact block needs to be generated while recording to the blockchain and ensuring the integrity of the new transaction data. The work involves intensive computation. If a given miner succeeds in generating the block first, and the block is approved and added to blockchain, Bitcoin is issued as a reward to the miner. Data fraud is prevented and Bitcoin is kept integrated and safe through the above process ("mining").

6 Things You Didn't Know About a Blockchain
Blockchain explained! Here’s how to understand the blockchain & the technology behind Bitcoin & cryptocurrency. A blockchain is essentially a super secure form of record-keeping. It’s made up of a list of digital transactions, information, data, or whatever else you can think of, that are grouped together in “blocks” then added to a row of past blocks to form a “chain,” hence the name “blockchain.” What powers the blockchain is a network of computers (or nodes) working together to verify each transaction & adding it to the chain of blocks so it’s viewable to the public & can’t be changed or edited retroactively. This makes it virtually impossible for human error to ever occur, therefore ensuring the blockchain’s long-lasting integrity. Blockchains operate autonomously, meaning they’re self-governed & their actions are carried out without any outside control or influence whatsoever. In the case of Bitcoin, it solves the problem of double-spending by ensuring that each unique transaction doesn’t occur more than once. Like I said earlier, data on the blockchain is resistant to any modifications. The only time it can be retroactively altered is when a majority of the computers in the network agree to let these modifications take place. But doing so consequently alters subsequent blocks. If I wanted to send you $1,000 using a traditional bank wire, I’d have to pay between $35-$45 in fees & wait between 3-5 business days for you to get your money. It’s because blockchain technology’s autonomous nature allows for transactions to take place directly from one person to another without the need for third-party services to regulate the transaction. It simply facilitates the transaction for cheaper & faster. It’s also extremely secure. Not only is its foundation based on cryptography, but its decentralized nature means there’s no single access point in which hackers can exploit it, making vulnerabilities within the system practically non-existent. Basing it in one specific location makes it “centralized.” Blockchains are “decentralized,” meaning their information is stored on thousands, if not, millions, of network computers all across the globe. Any hacker looking to taint the data would have to access each & every one of these computers at the same exact time! Ledgers based on blockchain technology are also open & public, making them easily verifiable. Anyone can view any transaction for any amount at any time, while still keeping user identity anonymous. Additionally, it’s designed to check in with itself in a sort of self-auditing manner. Satoshi Nakamoto was the first to conceptualize & implement blockchain technology when he introduced Bitcoin to the public. As I said before, the Bitcoin blockchain is upheld by a network of nodes that verify each & every transaction in a process as “mining.” Mining involves setting up a computer & connecting it to Bitcoin’s blockchain network using a client designed specifically for validating & relaying transactions. Once connected, the computer is automatically required to download a copy of the entire blockchain. It’s at this point that the computer can begin solving complex mathematical puzzles to verify transactions in a process called “proof-of-work.” Once a puzzle has been solved, the transaction is added into a block, a new copy of the ledger is distributed to the entire network, & the miner is rewarded with a certain amount of Bitcoin. Now, say you’ve sent me 1 BTC, the transaction has been verified, & it’s been added to the latest block; since then, another newer block has been created & added to the chain. It’s said that the block in which our transaction can be located is “1 block deep.” Most merchants & exchanges won’t consider the transaction confirmed until it’s 6 blocks deep or more. Doing so prevents any possibility of double-spending from occurring. These days, a new group of BTC transactions is accepted & formed into a block every 10 minutes on average. There are currently over 1,100 new cryptocurrencies available, most of which use different technology. Bitcoin’s primary function is a transfer of value directly from one person to another...but that’s just the tip of the iceberg. One such other cryptocurrency is Ethereum, which we’ll discuss in further detail later since it warrants its own video. To give you the gist of it though, Ethereum allows for smart contracts to function & also acts as a platform for developers to create & deploy other decentralized applications aka “Dapps.” Storj will take your photos, break each photo up into smaller files, encrypt each file for safety & security purposes, then distribute them to be stored across other hard drives within the Storj network.
