Description
Hash all public inputs of each proof down to 1 public input.
Changed all .code files to include a publicInputHash, which is the hash of all previously public inputs.
Changed both shield contracts: parameters, added a check on the publicInputHash Edited bit-lengths of commitments, nullifiers, and roots to 256-bit. The intermediate merkle nodes retain the 216-bit length. The publicInputHash is 248-bits; for maximal security within the field size.
Changed node.js controllers to deal with this new publicInputHash. Edited / added some zkp-utils functions to solve problems relating to hashing and padding.
Motivation and Context
Preparation for batching.
