IPSQL

A decentralized SQL database that runs on IPFS, implementing SQL schema, data model, and query language. Currently at v1.2.18 in pre-alpha stage with heavy active development and frequent breaking changes. Not production-ready. Uses chunky-trees for ordered search indexes and IPLD for data structures. Supports CREATE/INSERT/UPDATE/SELECT with WHERE, ORDER BY, aggregation functions (MIN, MAX, COUNT, AVG, SUM), optional encryption, and DAG tables (JSON-like unstructured rows). Key differentiator: every operation produces deltas and proofs for replication as hash-linked blocks. Does NOT yet support full SQL (e.g., JOIN, GROUP BY, DELETE without WHERE, DATE types).
