Blockchain & Distributed Ledger Architecture: Consensus, Cryptography, and Smart Contracts

Distributed ledgers from the mathematics up: hash and Merkle constructions, the consensus family beyond Proof-of-Work, and the applied surfaces — supply-chain provenance, self-sovereign identity, and smart contracts as an agent coordination substrate.
