@nourharidy The current scope of Zinc doesn't include support for smart contract operations, it is just pure ZKP for now. However, it will be added once ZKP circuit functionality is stable.
@gluk64 Looks like it is poseidon_hash. I am looking for poseidon_eddsa.
oh, I see. @shamatar ?
i can't post in the zinc channel for some reason
I've created a PR that includes a script to help get people hacking faster zpreview/public#2
Hey Matter Labs team! Been following from a distance and am just curious as to when you anticipate smart contracts being able to be run?
Thank you @thebkr7 -- merged! Please try to relogin, everybody is posting in the zinc channel
There was never a Poseidon EcDSA implemented (Schnorr signature to be precise. Keep in mind that EDDSA is very specific protocol). But it’s composable, there is no problem to take the current MuSig implementation and swap sha256 to Poseidon hash
Hi, I just want to check what the verification time for redshift is given that it was not mentioned in the paper
Hi, colleagues! I am using sapling_crypto_ce::poseidon::poseidon_hash in Rust. I need to calculate the exactly same hash in Solidity. I've tried Circom hash function generation, but it uses another seed scheme, which cannot be easily changed. Are you aware of any solution? I mean, tried to implement the same hash in Solidity?
Hi - can anyone here help with withdrawing Gitcoin grant money that is stuck in ZKsync with a Gnosis Safe wallet? Thanks
is this Gitter active? Am i even in the right place?
There is a separate zksync one here https://gitter.im/matter-labs/zksync, but in short there are public functions in the contract like getBalanceToWithdraw and corresponding WithdrawERC20 and WithdrawETH that you can use to get the available withdraw values for your Ethereum address and proceed with the withdraw. I assume you did trigger the withdraw procedure from the zksync itself and funds are now held by Ethereum contract
Hi @shamatar thanks for the info. sorry, i have not triggered anything. I believe the funds are still on ZKsync, which is where they ended up during Gitcoin Grants round.
Then you would need to trigger the withdraw first using the wallet interface. In any case use a zksync channel or a discord’s zksync channel for a conversation
Hello Team, need to know the rerequisites to run the zkSync setup on an Amazon Linux EC2 instance as I'm facing issues with "zksync init". A detailed setup document on Amazon Linux EC2 instance will be much appreciated. Thanks
