海外TECH	DEV Community	But why do we need Blockchain, anyway? And why does it need us just as much?	https://dev.to/manbir/but-why-do-we-need-blockchain-anyway-and-why-does-it-need-us-just-as-much-115p	But why do we need Blockchain anyway And why does it need us just as much Out of all the cult surrounding Bitcoin many people think of blockchain as the technology that powers it While it s true and that was its original purpose blockchain is capable of a lot more thanks to all the innovation happening Also we don t hear the term blockchains quite often but that s a term because there are a whole bunch of them Blockchain is in fact a shorthand for a whole suite of distributed ledger technologies that can be programmed to record and track any type of value for example from financial transactions and medical records to property land titles You might be thinking that we already have processes to track and store data then what s so special about blockchain Let s dive into the reasons why blockchain technology is here to revolutionize the way we store and interact with data along with why blockchain needs us just as much we need it Storing and Tracking DataWhile many people relate blockchain with cryptocurrencies it has more to do with how we store and manage data Blockchain stores information in batches called blocks There are multiple of them that are linked together in a chronological order that can not be modified forming a continuous line metaphorically a chain of blocks If we want to make a change in the information in a particular block in between the chain we can not do that simply by rewriting the data in that block Instead the change is stored in a new block after the most recently created block depicting that x changed y at a particular date and time To software engineers this might sound familiar reference git Leaving even git aside it might still feel familiar to you because blockchain is based on the centuries old method of the general financial ledger making it a non destructive way to track data over time As an example say there are two siblings Anne and Harry in a dispute over who owns a piece of land that has been there in the family for centuries Now since blockchain technology uses the ledger method it would hold an entry in the ledger showing that Josh one of Anne and Harry s ancestor owned the property first say from to then transferred it to Bill another ancestor forming a new entry in the ledger and so on until it got transferred to Anne in by her father making Anne the current owner We ll be able to see that history of transfer of ownership for the piece of land in the ledger along with date and time Unlike the old age ledger method being on a notebook or a computer all that data can never be tampered or deleted over blockchain because of its decentralized nature which brings us to its second unique property Distributed and DecentralizedBlockchain is designed to be decentralized meaning that it can not be controlled by any individual organization or government institution The data is distributed over a large network of computers So if any entity wants to change the data they ll need to change it on all the computers that hold that dataーwhich is nowhere near feasible thus making blockchain tamper proof All this creates trust in the network of blockchain users Before a block gets added to the chain an algorithmic problem must be solved to validate an action over the network for example a transaction The computer that solves the problem called nodes shares the solution with all the other computers over the network This is called Proof of Work PoW The network then works on verifying this PoW thereby reaching a consensus and if it s correct the block gets added to the chain One of the major benefits of having a decentralized and distributed network is that in case one of the nodes go down there would still be multiple up and running to validate the transactions and share data with rest of the nodes represented in the GIF above The combination of these complex computational problems along with verification by a large number of computers collectively ensures that we can trust every single block on the chain Because the network does the trust building for us it brings us the opportunity to interact with the data in real time also bringing us to the third major property of blockchain No Requirement for IntermediariesCurrently when dealing in business we don t show the other party our financial or business records We instead rely on a trusted intermediary such as a broker bank or lawyer We also trust them to keep our information confidential For example Uber connects a passenger with a driver and ensures that the ride is carried out efficiently In the process additional time and money is involved and we also give out our personal information like contact address etc to Uberーwhich has nothing to do with the data after a ride They may or may not hold your sensitive data after the ride Now what if a passenger could get in touch with one of the nearby drivers directly Taking an example of voting in elections how do we make sure that the count of votes going to a particular political party is genuine How do we make sure that every citizen in a country gets an equal opportunity to vote just by being a part of it without requiring any additional document How do we make sure that there s no human error in the counting of votes in case of ballot casting By relying on algorithms that can be audited anytime by anyone in the world Blockchain works to solve such type of problems Taking back the example of Anne and Harry in real world a lawyer would have to sort out the dispute to verify that Anne is the rightful owner of the land by looking at the records thus data getting exposed to the middleman If Anne s ownership information was stored in the blockchain she could independently retrieve the information about her property from there Now since the data on blockchain is verified to be true by multiple computers instead of a single human intermediary Anne could simply show that data to Harry thus saving a considerable amount of time and money that would ve been invested while dealing with a lawyer This type of trusted peer to peer interaction with data can revolutionize the way we access verify and transact with each other by leveraging the power of algorithmic computations Since blockchain is a type of technology and not a single network it can be implemented in many different ways While some blockchains can be completely public for anyone to view and access at any time others can be closed to a select group of authorized users such as an organization group agency or government institution like banks There can be hybrid public private blockchains too where anyone can see the public data but only authorized parties can see the sensitive data All the three properties above collectively contribute to allow groups of people who are anonymous and don t know each other to establish trust between each other This develops a democratization in the data which can significantly reduce fraud and mismanagement due to human errors Now that we know why we need blockchain how does the inverse hold Blockchain needs us users and early adopters just as much we need it in the form of developers miners investors validators liquidity providers educators and other form of contributors because the power of a blockchain is in its community The bigger the community of a blockchain network becomes the more trust is established not just because we ll have more computational power to validate transactions but also because we re building an ecosystem in which the use cases are linked together between products that can co exist to form a workflow each providing a separate solution to a real world problem that gets solved on chain To sum it up we re building a new generation of internet on which data is driven by trust and we re doing it on the internet of value that requires relentless adoption and meaningful contribution And we want you to on board towards this new era of innovation Come join us with ️by Manbir	2021-11-07 12:49:27

海外TECH	reddit	Why dog coins are so popular but cats are not? We finally have the answer to both questions!
