Introduction A blockchain is an integrated solution of different computer science problems in the form of a single, append-only, publicly available, transparent, and cryptographically auditable database that runs in a distributed and decentralized environment. I’ve heard many times that blockchain is a technology looking for a problem to solve. I disagree with that assessment because the tech and computer science behind blockchain has practical uses in everyday engineering problems. One use of this technology that comes to mind is a dependency management verification system.
