海外TECH	DEV Community	Demystifying Blockchain Technology	https://dev.to/ieeecsvitc/demystifying-blockchain-technology-2gj4	Demystifying Blockchain TechnologyOverview To thrive in this rapidly changing amp globally competitive environment businesses have no option but to be agile resilient amp innovative This calls for digitalization of the processes which has been accelerated by COVID amp Industry The key challenge to digitalization is Data Security amp Transparency To address these challenges Blockchain has emerged as a possible antidote to one of today s most vexing online business challenges ーhow to create greater trust transparency and accountability for all who wish to transact and interact online Key TakeawaysUnderstanding Blockchain TechnologyWhy use Blockchain How does it work What are the opportunities When to use Blockchain Origin and History of BlockchainIn Satoshi Nakamoto An Anonymous person persons first generated and implemented the first blockchain database as a infrastructure for the bitcoin the first cryptocurrency ever created Satoshi Nakamoto used block and chain separately in his paper in October Later with time it became a single word blockchain From onward blockchain is the term being referred to new applications of blockchain Role of BlockchainIndustry the cause of the fusion of physical and the virtual world has come much forward around the type of technology which have come up around advanced robotics D printing IOT Artificial intelligence big data etc They are the key technologies around but the problem with this has been now when we talk of technology many of us are using it whether we are using digital I mean robotics part whether we are using data analytics it has improved the convenience speed and efficiency certainly but the key thing which we are suffering in the technology is the time of transit from between the transaction and settlement you have all the best technologies around now a days but the time cycle is very long it s more of a linear path then there s a duplication of efforts if you have or players involved in the whole supply chain each one is maintaining his own ledger then which one is the truth nobody knows it and if information is all centralized and the centralized data can be changed around so the trust is gone anybody can hack into the centralized system that s the way they lack the trust and the data security We are moving toward digital era but people are having worrisome the more we become digital anybody can hack our data so the concept of blockchain basically avoid those issues around this is how the blockchain come if you look in this the technology enablers which have come from industry like IOT robotic process d printing augmented reality cloud AI cyber security of which we all are aware but the cyber security is not serving the purpose around in many places so the blockchain which is overriding you can see it s a new way of securing a trust transferring the values and storing the data the new way means it is not centralized information Today when I am having or people in the whole supply chain and every information if it is particularly dealing with funds is going to the bank if anything else is going to some other servers and those servers are centralized so anybody can hack and change it but the moment the blockchain concepts come it s a more of a distributed concept so it s not a centralized a decentralized database and the moment it is decentralized it s not easy to change so that s how the blockchain is coming into our industry What is Blockchain In the simplest terms Blockchain can be described as a data structure that holds transactional records and while ensuring security transparency and decentralization You can also think of it as a chain or records stored in the forms of blocks which are controlled by no single authority A blockchain is a distributed ledger that is completely open to any and everyone on the network Once an information is stored on a blockchain it is extremely difficult to change or alter it What does it mean to be decentralized Traditional ledgers are centralized use rd parties and middlemen to approve record transactions Blockchain distributes ledgers across network or participating node no central authority required similar to peer to peer torrent file sharing How does it work At its core blockchain brings together an ecosystem of partners who all choose to collaborate to address inefficiency There are tenants of the technology that everyone needs to understand Shared Immutable VisibilityPrivacy Blockchain Technology leverages years of research and development in cryptography Smart Contracts Blockchain smart contracts are not legal documents so don t think of it that way Trust Consensus Here again Blockchain leverages cryptography When an event is published to the ledger the algorithms do a couple of things First the identity of the participant publishing the transaction is validated by other participants Blockchain owes its name to the way it stores transaction data in blocks that are linked together to form a chain Each block contains a hash a digital fingerprint or unique identifier timestamped batches of recent valid transactions and the hash of the previous block In a nutshell here s how blockchain allows transactions to take place A blockchain network makes use of public and private keys so as to make a digital signature ensuring security and consent Once the authentication is ensured through these keys the necessity for authorization arises Blockchain allows participants of the network to perform mathematical verification and reach a consensus to agree on any particular value While making a transfer the sender uses their private key and announces the transaction information over the network A block is made containing information like digital signature timestamp and therefore the receiver s public key This block of data is broadcasted through the network and therefore the validation process starts Miners all over the network start solving the mathematical puzzle related to the transaction in order to process it Solving this puzzle requires the miners to take a position their computing power Upon solving the puzzle first the miner receives rewards within the sort of bitcoins Such quite problems is mentioned as proof of work mathematical problems Once the bulk of nodes within the network come to a consensus and comply with a standard solution the block is time stamped and added to the prevailing blockchain This block can contain anything from money to data to messages After the new block is added to the chain the prevailing copies of blockchain are updated for all the nodes on the network Consensus MechanismProof Of WorkProof of work PoW describes a system that requires a not insignificant but feasible amount of effort in order to deter frivolous or malicious uses of computing power such as sending spam emails or launching denial of service attacks The concept was subsequently adapted to securing digital money by Hal Finney in through the idea of reusable proof of work using the SHA hashing algorithm Proof Of StakeProof of stake PoS reduces the amount of computational work needed to verify blocks and transactions that keep the blockchain and thus a cryptocurrency secure Proof of stake changes the way blocks are verified using the machines of coin owners The owners offer their coins as collateral for the chance to validate blocks Coin owners with staked coins become validators What makes blockchain so lucrative to business First of all it reduces operational costs The removal of intermediaries may be a boon for business because it not only reduces cost but also reduces the purpose of contact ーimproving efficiency and growth Transactions speeds also are improved to a replacement height For businesses it s all about efficiency if they will keep their accuracy intact The use cases also are in favor of business Some companies have already shown their interest in blockchain The Dubai Blockchain Strategy is one example The Dubai Blockchain Strategy will help Dubai to be the first city fully powered by Blockchain and make Dubai the happiest city on earth The strategy will be using three strategic pillars government efficiency industry creation and international leadership How Will Blockchain Disrupt Industries Several industries like Unilever Walmart Visa etc use blockchain technology and have gained benefits in transparency security and traceability Considering the benefits blockchain offers it will revolutionize and redefine many sectors Here are the top prominent industries that will be disrupted by blockchain technology in the near future BankingCyber SecuritySupply Chain ManagementHealthcareGovernment ConclusionThis leads us to the end of our article “Demystifying Blockchain Technology Blockchain is undoubtedly important to our society It s an impact on the current industries It is unparalleled With the growth of BaaS and other improvements it is the only time when most of the industry will start adopting blockchain So what do you think about blockchain Do you see the benefits	2022-01-09 17:02:16
