@ddsm/core

Pure-functional core of the DDSM protocol — token types, validation, proof verification, log compaction, and selective disclosure. No I/O, no side effects.

Install

npm install @ddsm/core

What's in the box

| Export | Description | |---|---| | DDSMToken, SchemaManifest, LogEntry | Core protocol types | | parseToken | Parse and structurally validate a raw token object | | verifyProofChain | Verify every log entry signature back to genesis | | getTransitionContract, validateParams | Manifest-driven transition rules | | applyTransition | Compute the next token state | | compactLog, verifyLogRoot | Log compaction and root verification | | encryptParams | Field-level selective disclosure |

Usage
