It consists of a chain of blocks and each block contains a secure group of transactions of money, bitcoins, contracts, property, etc. without any need for third-party middle-man such as central authorities, banks, government, etc. Transactions are verified by a network of computers. Once a block of information is created in the chain, it can’t be changed or deleted. This makes the blockchain very secure and trustworthy. It is a software protocol, it never runs without the internet.A Blockchain is a chain of blocks that contains information about transactions. On completion of a transaction, it will go to the blockchain's permanent database. It is mainly used for secure transactions without any third-party involvement in between. To visualize blocks, transactions, and blockchain network metrics, you can use blockchain explorer.Why Do We Use Blockchain?Blockchain is a distributed digital ledger of transactions. It changes the whole concept of the transaction now we don’t have any need for centralized authorities to verify our transactions, blockchain makes it decentralized and secure. The security is maintained by cryptographic processes performed by p2p users, through the process called Data mining Here are some important features given below:SecureTransparentTamper-proofPeer-to-peer transactionRecent Articles on BlockchainIntroduction to Blockchain TechnologyIntroduction to Blockchain TechnologyHistory of BlockchainFeatures of BlockchainImportant Blockchain TerminologiesDifferent Versions of Blockchain Types of BlockchainPublic BlockchainPrivate BlockchainHybrid BlockchainConsortium BlockchainApplications of BlockchainAdvantages and Disadvantages of Blockchain Benefits of Blockchain TechnologyHow Does the Blockchain Work?Need of BlockchainPeer-to-Peer NetworkWhat is Decentralization?What is Ledger?What is Blockchain Distributed Ledger?Difference between Centralized and Distributed LedgersDifference between Public and Private LedgersCryptographyCryptography and its TypesCryptography in BlockchainBlockchain Hash FunctionBlockchain - Block hashingHow Block Hashes Work in BlockchainWhat is Digital Signature?Blockchain – Public Key CryptographyBlockchain - Private Key CryptographyBlockchain Merkle TreesWhat is Cryptographic Primitive in Blockchain?Blockchain - Elliptic Curve CryptographyHow to Create a Public/Private Key Pair?Blockchain - Encrypt & Decrypt Files With Password Using OpenSSLBlockchain - Elliptic Curve Digital Signature Algorithm (ECDSA)Blockchain Resolving ConflictsApplications of Homomorphic Encryption in BlockchainConsensus AlgorithmsConsensus Algorithms in BlockchainBlockchain Proof Of WorkProof of Work Consensus algorithmProof of Burn Consensus Algorithm in BlockchainProof of Stake (PoS) in BlockchainByzantine Generals Problem in BlockchainCryptographic Consensus Mechanisms in BlockchainDelegated Proof Of Stake (DPoS)practical Byzantine Fault Tolerance(pBFT)Blockchain ArchitectureBlockchain StructureGenesis Block in BlockchainCandidate Block in BlockchainActors Involved in Blockchain SolutionBlockchain Transaction Life-cycleBlockchain ForksBlockchain and Block HeaderComponents of Blockchain NetworkBlockchain Incentives to MinersCore Component of BlockchainBlockchain Protocols and Their WorkingBlockchain – Resolving ConflictsWhat is Blockchain Authentication?Blockchain and CryptocurrencyWhat is Blockchain Cryptocurrency?Cryptocurrencies BenefitsHow are Cryptocurrencies createdWhat is a Cryptographic TokenNon-Fungible Tokens (NFTs)What is Cryptoeconomics?What is an ICO?Generalized Proof-of-Stake Mining in CryptocurrenciesBlockchain - Electronic CashWhat is Blockchain Wallet and How does it workSmart Contracts and Decentralized Applications (DApps)What is EthereumComponents of the Ethereum NetworkDifference between Ethereum and BitcoinWhat is EtherEthereum AccountsNodes and Clients in EthereumWhat is Ethereum Virtual MachineEthereum – Gas and FeesWhat is a Smart ContractHow to Test a Smart Contract for Ethereum?How to Simply Deploy a Smart Contract on EthereumHello World - Smart Contract in Remix-IDEDecentralized Apps (dApps) in BlockchainWhat is an Ethereum APIPros and Cons of DappsWhat is a Dao?Blockchain SecurityBlockchain and Data PrivacyBlockchain and KYCRole of Blockchain in CybersecurityBlockchain to Secure IoT DataBlockchain ApplicationsApplications of Blockchain in Data ManagementTop Applications of Blockchain in the Real WorldBenefits and Applications of Blockchain in Cloud ComputingIntegration of Artificial Intelligence and BlockChainHow Blockchain Can Change the Future of Banking?Blockchain – Into the FutureBlockchain in GenomicsIntegration of Blockchain and AIUse Cases of BlockChain in different fieldsRole of Blockchain in Sustainable DevelopmentApplications and Uses of BlockchainBenefits of Blockchain in HealthcareDecentralized Voting System Using BlockchainBlockchain ImplementationCreate a simple Blockchain using PythonImplementation of Blockchain in JavaBuild a To-do List Web Application Powered by BlockchainFlutter and Blockchain – Hello World DappBlockchain Gaming: Part 1 (Introduction)How to Use GANACHE Truffle Suite to Deploy a Smart Contract in Solidity (Blockchain)?How to Use MetaMask to Deploy a Smart Contract in Solidity (Blockchain)?Build an Authentication Using the BlockchainMiscellaneousPublic Blockchain vs Private BlockchainBlockchain vs DatabaseProof of Work (PoW) vs Proof of Stake (PoS) DAG vs BlockchainHot Wallets vs Cold Wallets in BlockchainBitcoin vs CryptocurrencyFull Payment Verification vs Simple Payment Verification in BlockchainBitcoin vs BlockchainHyperledger vs EthereumBlockchain vs HashgraphQuorum BlockchainWhat is EOS Blockchain?DAO(Decentralized Autonomous Organization) in BlockchainWhat’s the connection between Java and Blockchain?Top 10 Programming Languages for Blockchain DevelopmentHow does Blockchain support Crowdfunding?
