Why the models rank TigerBeetle — on best double-entry ledger databases for fintech developers
“The only database purpose-built for double-entry accounting at the storage-engine level — debits/credits are first-class primitives with balance invariants enforced in the database, not application code; extreme throughput (hundreds of thousands to ~1M transfers/sec) with strict serializability, deterministic simulation testing and storage-fault tolerance that no general-purpose DB matches; open source (Apache 2.0) with commercial support, and by 2026 it has real production adoption in payments and switching. Assumption shaping rank: the practitioner needs a correct, fast ledger core and accepts pairing it with a general-purpose DB for everything else.”
