    We are excited to reveal our vision for ZK Sync: a trustless scaling and privacy solution for Ethereum, with an emphasis on great user and developer experiences.

    This is a big step towards ZKP-secured smart contracts in zkSync.

    Excited to announce the long-awaited alpha release of Zinc framework — a programming language and execution environment for easy creation of safe zero-knowledge proof circuits (programs to run on ZKPs).

    A perfect first use-case for zkSync. It can support 1000x increase in volume at a fraction of the current cost. zkSync SDK and testnet are ready for integration.

    In we are going to experiment with this idea to the extreme — create a class of validators (Guardians) with not only low computational requirements, but also low security requirements (b/c zero risk of slashing): run your node on a laptop or any cheap cloud instance.

    There are two other anti-centralization techniques that the post misses. The first is to have forgiving protocol rules that do not require nodes to have especially high performance. Make sure even 70% uptime validation is net-profitable, don't have ultra-fast block times, etc.

    Excellent analyzis of PoS centralization/security.

    1/ Coinbase adds automatic staking for XTZ, and less than a month later, Binance introduces 0% staking fees on Tezos. Stake wars are just getting started, and things are already starting to feel a liiittle uncomfortable. A thread on centralization in Proof of Stake (PoS):

    Congrats ! Groth16 is the fastest SNARK we ever had, outperforming it marks a huge step forward. P.S. These optimizations also apply to the PLONK-based by .

    The benchmarks are out and PLONK with custom gates is ⚡️ lightning fast 2.5x faster than Groth16 on MiMC and 230k gas! Fast privacy on is coming 🔥

    A lot of people commented that there's not enough usage to need scaling. It's true that usage is tiny, yet when you move beyond just simple transactions, you exponentially increase the demands per user. Both bitcoin and ethereum reached full blocks* in 2017. Even just 1000

    In 6 months, most dApps will be scaling with:

    This is both a cool new technical implementation of zk-SNARK tech, and also one of the best written essays I've read in crypto. It's not easy covering arcane technical topics with such an approachable and clear style.

    > If stateless clients prove infeasible, then is there a viable alternative for Eth2? Eth2 is largely a data layer and most interesting stuff happens inside of rollups.

    The awareness is raising. People do care.

    Fascinating new Pew report on privacy in America. A few tidbits: 📌 6/10 Americans don’t think it’s possible to go through daily life without having their data collected 📌 70% say their data is less secure than it was 5 years ago 📌 57% say they follow privacy news closely

    Are you convinced that all Ethereum research is a scam? Offer me your sharpest criticism of ZK Sync. This construct here is phenomenal. From what I can tell, it is what sidechains were supposed to be, but better: offchain, trust-minimized, scalable, final.

    These tokens will be sold via an auction on the mainnet. The sale revenue will be distributed to block producers to subsidize ZK proof generation costs.

    To allow anybody to become or nominate validators without asking for permission, after initial token distribution ZK Sync will have an ongoing inflation mechanism (~2% to 5% p.A.).

    This is a hardcore emergency mechanism. However, we invested a lot of thought into making even the normal ZK Sync operation as permissionless as possible.

    Users who feel censored can always request an exit via the priority queue on L1. If the requests are not served within a reasonable timeout (e.g. 1 week), an Exodus mode is triggered. It means that the validators are dead. Now everybody can exit directly on L1.

    The promise of ZK Sync is that funds are as safe as underlying L1 itself. This would not be true if exits could only be initiated via validators (no matter how well decentralized). Solution: a priority queue. Check out

    ZK Sync is permissionless. Period. Thread 👇

    's ZK Sync (which is an otherwise incredible achievement from a stellar team) allows a majority of token holders to censor transactions arbitrarily for free (or at most, for the price of a majority of the tokens). In other words, ZK Sync is permissioned.

    This is why we're creating Zinc.
