crypto-database

The database that can prove it never lied.

PyPI npm crates.io Python licence free under $1M

One version across npm · PyPI · crates.io — every release ships aligned.


crypto-database is a content-addressed, hash-chained, time-traveling datastore. Every version of every record is an immutable, BLAKE2b-verified object in a Merkle DAG — nothing is ever overwritten, and the store can prove its own integrity on demand.

If your data is evidence — ledgers, audit trails, provenance, anything you may one day have to defend — crypto-database makes the history itself tamper-evident and replayable.

Why crypto-database

  • 🔒 Tamper-evident by construction. verify() re-hashes every object against its content address. Flip a single byte on disk and it's caught — silently impossible to forge history.
  • ⏪ Time-travel is a query. AS OF <seq> returns the exact state at any point. VALID AS OF <time> adds bi-temporal validity — what was true, as of when.
  • 🧬 Causal provenance. caused_by links every record to the facts that produced it; TRACE walks the graph. Audit why, not just what.
  • 🔐 Encrypted at rest (AES-256-GCM), RESP2 wire protocol, SQL / Redis / Mongo adapters, a nedbd-v2 server daemon.

Install

npm install crypto-database   # Node (native addon)
pip install cryptodb          # Python  ← note the PyPI name
cargo add crypto-database     # Rust

Why the split name? crypto-database was already taken on PyPI by an unrelated project, so the Python distribution keeps the original cryptodb name there. npm and crates.io publish as crypto-database. Same engine, same version, same code — only the registry labels differ.

Reach for it when

Audit logs · financial & token ledgers · compliance trails · supply-chain provenance · anything where provable, replayable history is the product, not a nice-to-have.

import { NedbCore } from "crypto-database";
const db = new NedbCore();
db.put("ledger", "acct:alice", JSON.stringify({ balance: 100 }));
db.put("ledger", "acct:alice", JSON.stringify({ balance: 250 }));
db.getAsOf("ledger", "acct:alice", 0n);   // → balance 100, the past, intact
db.verify();                               // → true: nothing was tampered

crypto-database (previously CryptoDB) is a distribution of the NEDB engine, tuned for verifiability. Engine development happens upstream at Eth-Interchained/nedb. © Interchained LLC.
