    Hey
    Alex G
    @gluk64

    Could you share the idea of how you envision that private txs will be possible in the future?

    The exact scheme will depend on a number of factors. There is definitely utility already in hiding the amounts, although ultimately you need to hide the interaction either. However, level of privacy increases the cost of the transaction. Thus, at the end it will be up to market to see what people are willing to pay for and how far we are with the scalability efficiency by then.

    Hello, could you help me to find the implementation of Poseidon_Eddsa for circuit (bellman_ce)? Is it exist?

    Would it be possible to improve on-chain space efficiency by distributing computation of validity proof generation in a zk-rollup? (assuming gained computation power)

    @notyourkeys_twitter
    Could something like github/matter-labs/snarkyGPU be applicable to something like zkSync?

    Hey guys, I've read the Zinc v0.1 docs and I can't find any instructions regarding handling tokens/ETH. Can you help me with that?
    @notyourkeys_twitter definitely
    @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.

    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?

    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 all. Grate on the launch. I’ve already started hacking in new stuff
    Curious on the new circuit language. Where could I read about it?

    I have! Seems like perhaps subscriptions might work on the protocol level too.
    If transactions themselves could become EIP 1337 compliant or a variant that would be dope vs having to build out contracts that ultimately just manage allow for programmatic txns.

    When will the zkSync v2 be launched?

    sir may i ask can i using zksync mainnet to deposit erc20 token to the exchanges?

    @SCBuergel
    Hi guys - just made my first tx on zkSync - cool stuff!
    Some questions:
    1. It would be awesome to have a multi-send feature, is that feasible? would make my life easier using zkSync for bounty payouts for our HOPR bounty sessions
    2. It seems that the withdraw tx is coming from your relayers, why can I not broadcast that tx myself? I'm asking because maybe you're too pricy for me and I want to have a cheaper gas price ;)
    Sebastian C. Bürgel
    @SCBuergel
    Actually addendum to (2). If I can't broadcast the tx myself then I can be held hostage in your L2, and validators can extort whatever fee they wish, correct?

    Hello~ Is the Redshift zk proof open sourced, or will it be open sourced in the future? Thank you

    Hey, I was wondering if you guys had heard back from Reddit yet regarding your submission? Anything at all or still on standby?

    @gluk64
    Reddit is currently evaluating all the submissions, we are in touch with them.

    Hey there, seems like ropsten zksync doesn't work, I sent few transactions today to deposit sync from ethereum and sync balance still nothing, ropsten zkscan also is silent
    Nikolai Bailo
    @nbailo
    Is it connected with ropsten reorg?

    Hey
    Do you have https://wallet.zksync.io/ open sourced? Would love to add QRCODE reader in it

    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?
    Alexander
    @shamatar
    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
    skyminert
    @skyminert
    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.
    Alexander
    @shamatar
    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
