crypto-database
The database that can prove it never lied.
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_bylinks every record to the facts that produced it;TRACEwalks the graph. Audit why, not just what. - 🔐 Encrypted at rest (AES-256-GCM), RESP2 wire protocol, SQL / Redis / Mongo adapters, a
nedbd-v2server 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-databasewas already taken on PyPI by an unrelated project, so the Python distribution keeps the originalcryptodbname there. npm and crates.io publish ascrypto-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.
