summary

Exonum exposes merkelized collections (proof map and proof list indices) stored atop RocksDB key‑value storage and signs a state hash in each block under PBFT consensus, claiming about 5000 tx/s and ~0.5s latency. A JavaScript light client receives JSON proofs (Merkle or Merkle‑Patricia paths) that validate a record against the block header; demoed with a timestamping app that builds and verifies proofs end to end and anchors state hashes to Bitcoin every thousand blocks.
