Immutable verification log for ORM operations with cryptographic integrity and event broadcasting.

Purpose

Maintains an append-only chain of signed blocks for auditable ORM operations. Each block contains a SHA-256 hash linking to the previous block, with RSA-signed payloads for tamper detection.

Role in Semitexa

Depends on semitexa/core and semitexa/orm. Optionally integrates with NATS (basis-company/nats) for cross-node event broadcasting. Hooks into ORM operations automatically via ResourceBroadcastListener.

Key Features

• Append-only block chain with SHA-256 linking
• RSA cryptographic signing via SignerInterface
• ResourceBroadcastListener hooking into ORM operations automatically
• NATS transport for broadcasting chain events
• Swoole-aware mutex locking for concurrent appends
• SQLite-backed local chain storage

Notes

The chain is local per node. NATS transport enables cross-node verification but is not required for single-instance deployments.
