BulletproofJS

This set of tools is not ready for production and is listed for use only for projects of BANKEX Foundation "Proof-of-Skill" hackathon in Moscow on 19-20th of May, 2018

Features

  • Set of local provers and verifiers for BulletProof range proofs (almost 1 to 1 compatible (hashing algo now always pads)) with the original work from Stanford).
  • Set of Ethereum smart-contracts for verification only, as well as libs for EC arithmetics and public parameters generation using "nothing up my sleeve" numbers.
  • Prototype Confidential Transactions contract taking care of various tokens, deposits, key exchange.
  • AES encryption for exchange of transaction values and blinding factors out of the box.

TODO

  • Add Ethereum smart-contracts for key derivation, although using it is HIGHLY DISCOURAGED on any non-user controlled node.
  • Improve key exchange to have separate viewing and spending keys.
  • Improve gas costs by may be adding shifts.
