Paper Title: Bulletproofs+: Shorter Proofs for Privacy-Enhanced Distributed Ledger.


  1. Due to distributed and transparent nature, short NIZK without a trusted setup is highly desired in the context of distributed ledger.

  2. This work presents an improved variety of Bulletproofs, that has shorter proof size than Bulletproofs.

  3. It achieves the shortest proof size in the category of NIZK without trusted setup. 

  4. The main ingredient is the zero-knowledge weighted inner product argument (zk-WIP) to which it reduces both the range proof and the arithmetic circuit proof.

  5. The benefit of reducing to the zk-WIP is a minimal transmission cost during the reduction process, which makes the overall proof size of Bulletproofs+ smaller than that of Bulletproofs.

  6. This work also has additional extensions such as aggregating range proofs and batch verification.
