Happy to announce that with my recent optimizations, Bandersnatch’s scalar multiplication circuit is reduced to 2600 constraints from 3100 constraints, resulting a 17% improvement over the Jubjub curve.
Introducing the Falcon-r1cs
I recently worked on a rust wrapper of the reference implementation for Falcon signature scheme. Also a rank-1 constraint system (R1CS) implementation of Falcon which shows falcon’s signature can be verified with some 80k r1cs constraints. The main ingredient is an almost linear time NTT based multiplication circuit that performs ring multiplications with 15k constraints.
Introducing the Bandersnatch curve
The Bandersnatch curve was discovered by Simon Masson from Anoma and Antonio Sanso from Ethereum Foundation. I have implemented this curve with rust. The group operation is 40% faster than the Jubjub curve. See here for a short report on this curve.
For personal reasons, I will be leaving Manta network. My last day at Manta will be 07/16/2021.
Manta submitted the first milestone for W3F open grants program
A few months ago, Manta network received the Web3 Foundation’s Open Grants Program to build a decentralized anonymous payment system for Polkadot. As part of the milestone 1 deliverables of this program, we are open-sourcing our code pallat-manta-dap, manta-node and manta-front-end.
