Every hash chain system today relies on the cloud. Ours doesn't. Modern cryptographic ledger systems face a fundamental tension between machine efficiency and human readability. Binary formats offer compact storage, fast random access, and
Trust is not a security strategy for hash chain. Verify or don't use it. State proofs provide cryptographic evidence of a ledger's integrity at a given point in time, enabling offline verification without continuous access to the full ledge
We proved hash chain works without permission from anyone. Hash chains form the foundational integrity primitive for cryptographic ledgers, append-only logs, and blockchain systems. This paper presents a formal analysis of SHA3-256-based ha
