Blake3 Tree
This library provides an optimized and SIMD-enabled incremental Blake3 verifier.
Why
The implementation of verifiable stream done in bao does not utilize the happy and fast route of the Blake3 implementation. There also other times that you want a good API and representation.
In any case you can rely on this library to operate under those circumstances.
Benchmarks
We care more about optimizing a server that is generating proofs. Since it is likely serving many clients so while implementing these structures and functionalities we focused on making sure the server side is as fast and efficient as possible.
The benchmark results should that generating a proof for a content takes less than 130 nanoseconds, the numbers on the
left are number of blocks (each block is 256KB) and there are two performance categories prefixed with -beginning and
-resume.
Since the proofs are sent over an stream we have two modes the first one generates/verifies the first proof in the connection, and from that point forward we can assume that the client already has the proof for any data that comes before the offset which we want to prove.
