# bellman "Community edition"
# Plasma cash history SNARK
Originally developed for ZCash, with extensions from us to make it a little more pleasant. Uses our "community edition" pairing for Ethereum's BN256 curve.
Compacts history in Plasma Cashes by hiding Merkle proofs under the private witness. Currently contains only non-inclusion circuit, with inclusion being trivially extended.
Without much optimization is requires 4270718 constraints for 128 block of non-inclusion for 24 tree depth.
Public inputs to the zkSNARK:
- Start of the interval index (if single coin - just index)
- Interval length (is single coin - 1)
- Set of roots for which this coin index is proved to be non-included
