Understanding Blockchain Fundamentals for Engineering Data Management

At it core, a blockchain is a disged ledger - a continuously growing ligt of recors, called blocks, that are linked using cryptography. Each block contens a batch of validated transactions, a timestamp, and a reference (hash) to the previous block, forming an immutable chain. The ledger is mainmaintained by a peer- to -peer network where every participant a copy, and changes te ledgere require consire sufrom the majority nodes.

Key Security Benefits for Systems Engineering Data

Kryptographic Protection andd Access Control

Data stored a blockchain is typically hashed or discripted before being distrided.
