    Thanks and happy new year.

    Hi @jenstark, and happy New Year!
    Privacy is not in scope of the current version

    @jenstark
    Ok thank you.
    Is there a roadmap for ZKSync?
    Alex G
    @gluk64
    We will publish updates as they appear

    Hi. Is it possible to compile bellman_ce as no_std package?
    Alexander
    @shamatar
    No, at the moment Vec type is used a lot and GlobalAllocator trait is not stable to be able to use existing collections in no-std environment. You can nevertheless compile it for WASM if it’s what you are interested in
    Maciej Zieliński
    @zie1ony
    Actually I want to use it as WASM file, but without panic handler.

    I use https://github.com/paritytech/wasmi so I can use only no_std.
    Alexander
    @shamatar
    I suppose it’s a part of substrate work? Unfortunately I’m not a wasm specialist

    @gluk64 is it possible to include some arbitrary data in the transfer within ZKSync network? some notes attached to a token transfer?
    Alex G
    @gluk64
    @scheneclk_gitlab it will be, but not right now. How do you intend to use it?
    Steve Chen
    @scheneclk_gitlab
    I plan to use it for decentralized token exchange

    Hi all, kudos for really great project! A quick q: is it planned to run one sidechain to rule them all, or is it envisioned there to be multiple? I take it validators are set in one place on the main-chain. Thanks.
    Alex G
    @gluk64
    It's most efficient if there is only one sidechain.

    @gluk64 Can I set up a dev environment and connect to a local POA network (parity Ethereum)?

    Could you share the idea of how you envision that private txs will be possible in the future? I've read that amounts will eventually be made private, however anonymity of users would require prohibitive modifications, is that still true? Thanks!

    Hey

    @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?

    @notyourkeys_twitter
    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?

    @nourharidy
    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.

    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?

    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?
