Blockchain is a peer-to-peer decentralized distributed ledger technology that 20provides the records of any digital
asset transparent and unchangeable and works without any third-party intermediaries. Blockchains are tamper-resistant
digital ledgers distributed in a distributed fashion. It is a digital collection of information about the transaction.
Blockchain was initially invented as a way of verifying the contents of a document using immutable timestamps. It was
designed as a way of ensuring authentication, immutability, and privacy. This paper consists of core concepts like proof of
work, proof of stack, Round Robin Consensus Model, BDAS working Algorithm, Agriculture Traceability Tools and
Technology Solutions, and an introduction to Ethereum in Blockchain.
