The financial transactions database designed for mission critical safety and performance.

Most teams treat testing as a necessary evil. TigerBeetle is built entirely on Deterministic Simulation Testing (DST).
Most teams build their software on top of loads of other software. TigerBeetle has zero dependencies.
Built to be storage fault tolerant..
TigerBeetle uses Protocol Aware Recovery to remain available unless all copies of a piece of data get corrupted on every single replica.
All data in TigerBeetle is immutable, checksummed, and hash-chained, providing a strong guarantee that no corruption or tampering happened.
TigerBeetle puts as little software as possible between itself and the disk, including a custom page cache, writing data to disk with O_DIRECT, and even running on a raw block device directly (no filesystem necessary — to sidestep filesystem bugs which do tend to happen from time to time).
They built their own implementation of LSM instead of using an off-the-shelf one – they call it an LSM Forest, which is something like 20 different LSM trees.
