Building Blockchains on the Go
summary
Live demo builds a runnable blockchain distribution in Go using gRPC and protocol buffers and a microservice layout, generating a genesis block named "genesis_hash", hashing blocks with SHA256, and linking them by previous-hash. Implements proto RPCs addBlock and streamGetBlocks, a server listening on :8004 and a client that appends a new block every second and consumes a continuous block stream. The code compiles, the server streams updated blocks, and hashes match in the demo.
