Actually I want to use it as WASM file, but without panic handler.

Alexander

@shamatar

https://github.com/rustwasm/console_error_panic_hook something like this?

Maciej Zieliński

@zie1ony

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

@thecryptofruit

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.

@scheneclk_gitlab

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

@thecryptofruit

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!

@Aveesh52

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?

Alex G

@gluk64

@shamatar

@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?

Nour Haridy

@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?

Alex G

@gluk64

@DryginAlexander https://github.com/matter-labs/sapling-crypto/blob/master/src/circuit/poseidon_hash.rs

@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.

Drygin Alexander

@DryginAlexander

@gluk64 Looks like it is poseidon_hash. I am looking for poseidon_eddsa.

Alex G

@gluk64

oh, I see. @shamatar ?

Hey

Luke Schoen

@ltfschoen

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

Benji Richards

@thebkr7

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?

Petr Korolev

@skywinder

@shamatar @gluk64

Alex G

@gluk64

Thank you @thebkr7 -- merged! Please try to relogin, everybody is posting in the zinc channel

Alexander

@shamatar

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

@jon-chuang

Hi, I just want to check what the verification time for redshift is given that it was not mentioned in the paper

Иван Иваницкий

@ivanitskiy_gitlab

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?

zkSync v1 is Live on Mainnet!

Congrats guys! Onwards and upwards.

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?

hello, is the developer(s) online?

Andrew Redden

@androolloyd

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.

@kiwizhang

When will the zkSync v2 be launched?

@bufrr

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

Sebastian C. Bürgel

@SCBuergel

Hi guys - just made my first tx on zkSync - cool stuff!

Some questions:

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
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
