Blockchain online training

Blockchain originally blockchain, is a growing list of called blocks, which are linked using Each block contains a cryptographic hash of the previous block, and transaction data (generally represented as a Merkle tree root hash).

a blockchain is resistant to modification of the data. It is “an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way”. For use as a distributed ledger, a blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for inter-node communication and validating new blocks. for best blockchain training visit follow link
