Crypto Secure Data Management with In-Database Blockchain

on YouTube ↗24m

" summary

Claim: Oracle adds a blockchain table keyword to enforce immutable rows via chained cryptographic digests, preventing updates even by DBAs and detecting disk‑level tampering when verification fails. Implementation details: digests chain row+previous, optional per‑row user signatures, an open source verifier lets outsiders recompute checks, and digests can be published for third‑party audit. Result: SQL‑level integration needs no app rewrite, supports analytics and the JSON‑relational duality, and runs at regular database speeds.
