Background and Description
=nil; Foundation as an initial member of Free TON community developed an upgraded version of TON Virtual Machine, which includes cryptographic primitives required for usage zero-knowledge proof verification within the virtualized applications. =nil; Foundation also prepared C++ (GitHub - NilFoundation/cpp-ton: Cryptography-enhanced Telegram Open Network Protocol C++ Implementation 2) and Rust-y (GitHub - NilFoundation/rust-ton: Cryptography-enhanced Telegram Open Network Protocol Rust Implementation 1) ZK proof verification instruction-enhanced TON protocol implementations.
Crucial application for such a verificaiton instruction is to verify rollups which often consist of transactions/replication packages/votes signatures etc.
Verifying transactions, votes etc. is all about verifying its signatures. Widespread signatures (EdDSA, ECDSA) are defined over non-pairing friendly curves (Ed25519, secp256k1) which have no twisted curves and induce high verification costs and timings. In case of FreeTON verification timings are required to be kept as low as possible.
Ths document proposes a contest results of which are supposed to introduce the way to efficiently verity non-pairing friendly curves-based signatures over BLS12-381-based Groth16 SNARK proof which would result in the introduction of a way to verify zk-rollups on FreeTON.
Instructions for participants
Participants are expected to introduce the way to efficiently verify EdDSA over Ed25519 signatures with the newly introduced VERGRTH16 instruction to make it possible to verify outside protocols zk-rollups inside the TVM.
General requirements
Solutions provided are expected:
To be a correctly functioning FreeTON virtualized application deployed either to https://main.ton.dev (https://ton.live) (in case the protocol gets upgraded) either to https://net.freeton.nil.foundation (https://nil.ton.live or https://live.freeton.nil.foundation) either to https://fld.ton.dev (https://fld.ton.live).
To involve VERGRTH16 TVM instruction usage.
To be able to verify a Groth16 proof of at least 32000 EdDSA over Ed25519 signatures within a single replication packet production interval.
Evaluation criteria and winning conditions
Apart from uploading a submission, a code should be submitted in accordance with GitHub - freeton-org/readme and deployed either to https://main.ton.dev (https://ton.live) (in case the protocol gets upgraded) either to https://net.freeton.nil.foundation (https://nil.ton.live or https://live.freeton.nil.foundation).
A participant should do a presentation of her solution at a convenient time agreed with Cryptography SG members. A solution should include tests with clear instructions.
If a test does not cover some scenarios, then jurors can develop their own tests, but it should reduce such a submission score.
The solution should have an open source license.
The solution should contain at least a draft of an architecture description.
Reward
Only submissions with an average score equal to or more than 5.0 can get a reward.
1st prize (score >= 7.0) - 300000 TONs
2nd prize (score >= 6.0) - 150000 TONs
3rd prize (score >= 5.0) - 50000 TONs
