Hello
Is the bounty still available?
Hi @ilblackdragon Very cool! We are currently building the exact same thing between tendermint to Ethereum. So far we have been able to create zk-proofs for a single ed25519 sig. The next step, do it for the entire validator set, and then the complete light client. If this grant is still open, let us know, we would love to submit a proposal for Rainbow.
Interesting, before I saw this Bounty, I submitted a high-level outline for this a couple of days back on the NEAR forum - https://gov.near.org/t/rainbow-upgrade-idea-using-zk-snarks-to-cheaply-verify-ed25519-signatures-on-ethereum-mainnet/7089
Progress Update: Hi @ilblackdragon We have already done the ED25519 and ECDSA signature verification implementation in a zero-knowledge circuit and verified it on EVM.
Hi @garvitgoel, is there any way to test it with the Rainbow Bridge?
I'm curious to know what is the cost of submitting such proof on Ethereum.
NEAR Bounty Terms
Before beginning work on the bounty, you must submit a proposal. Only if your proposal is accepted will you be able to claim the reward of the bounty. Your proposal should include time that it would take for your to complete this bounty.
There should be at most 1 week between proposal is accepted and you start working on the bounty.
Description
Light client for NEAR is relatively cheap in verifying, outside of set of ed25519 signatures of block producers.
Compressing the light block verification to just verifying of a single proof would provide a useful tool to sync blocks faster and use it in the Rainbow bridge.
Context
NEAR's light client specification is described here: https://nomicon.io/ChainSpec/LightClient.html
