Blockchain and Smart Contract
A blockchain is composed of a series of blocks, each containing a list of transactions. These blocks are linked together in a chronological order, forming a chain.
nlike traditional centralized databases, a blockchain is maintained by a network of computers (nodes). Each node holds a copy of the entire blockchain, ensuring that no single entity has control over the entire network.Transactions recorded on a blockchain are transparent and can be viewed by anyone with access to the network. Once recorded, transactions cannot be altered, providing a permanent and tamper-proof record.
A smart contract is a program that automatically executes predefined actions when specific conditions are met. These contracts are stored and replicated on the blockchain. Smart contracts eliminate the need for intermediaries by automating the enforcement and execution of agreements. This reduces the risk of human error and increases efficiency.Together, blockchain and smart contracts offer a robust framework for creating decentralized applications (DApps) that operate without the need for central authorities, fostering innovation and efficiency across various sectors.
