The latest @ZKsync governance proposal aims to reduce the execution delay for all ZK Chains from 21 to 3 hours.

In practice, this reduction greatly improves the UX for users (including CEX withdrawal times) and operational efficiency for builders and businesses.

🧵👇🏻 What is an execution delay?

When you send a transaction on any rollup, it’s not “final” immediately. Rollups derive their security from Ethereum, which means Ethereum needs to finalize your transaction. This happens when the rollup sends data and a proof of that data to an Ethereum smart contract to finalize.

⚖️ Execution delays for Optimistic Rollups are several days to account for their challenge period.

➕ Execution delays for ZK Rollups are very short due to ZK-proofs. However, most core teams extend this period as an added security measure.

.@NethermindEth and @the_matter_labs just completed the first formal verification of ZKsync's on-chain zk-verifier. This is a major milestone for ZKsync and blockchain security.

So, what does this mean? 🧵👇 2/10 What is a zk-verifier?

The zk-verifier ensures that ZK rollups process transactions correctly. It checks the correctness of zero-knowledge proofs, which are central to making rollups scalable and efficient.

zkSync protocol upgrade v24, on May 13th, has some HYPE updates for builders and users.

🌉 The zkSync bridge hub lays the foundation for interoperability between ZK chains
📱 Precompiles for signing transactions with Apple and Android devices
💽 Validium mode will soon allow teams to add a custom DA layer and base token for their ZK chain

Read more 👉 github.com/zkSync-Communi… ⚠️ Withdrawals from the official zkSync bridge will be disabled for 24 hours. Users can still use third-party bridges to withdraw.

ℹ️ v24 introduces a new shared bridge L1 contract. Funds will migrate from the old bridge to the new one. This is expected and your funds are safe.

We’ve memed it into existence, but what does it actually mean? @gluk64’s ETHDenver talk breaks it down 🧵 2/ The internet doesn’t run on a single server.

It's a global system with infrastructure owned and operated by people you've never heard of. Encryption helps secure the internet from most malicious actors despite many opportunities for interference.

Similarly, Web3 won’t run on a single chain. Right now, blockchains are evolving into a more complex network — L2s, hyperchains, DA, bridges, etc. Each new component creates an opportunity to censor.

ZK Proofs preserve trustlessness as Web3 goes mainstream.

The original vision for @zkSync was published 3.5 years ago, and it continues to hold relevance. @VitalikButerin's "3 Transitions" post highlights three of the five goals mentioned in our early roadmap: UX, privacy, and rollup-driven scalability.

zkSync Era and @DeFi_Dad hosted a panel featuring @mavprotocol, @mute_io, and @LiquityProtocol to discuss the next generation of DeFi and how projects can set themselves up for success. Top observations from some of the leaders building on zkSync Era👇

(1/7) Balance product-market fit & tokenomics

“DeFi 1.0 hit it out of the park on product-market fit. But then, many DeFi 2.0 projects over-engineered tokenomics and ended up with less of a product market fit. You must always balance both.” – @DeFi_Dad

Seamless UX is a prerequisite for mass adoption. zkSync Era’s native account abstraction equips developers with UX superpowers to onboard the first billion users to web3. Here’s what native AA unlocks for builders and how to use it on zkSync Era.

(1/8) ✅ AA = seamless UX

By upgrading users from externally owned accounts to smart contract accounts, developers can build experiences that abstract away seed phrases, schedule and automate payments, pay gas fees in any token — or even pay gas on a user’s behalf.

Gm! Yesterday, a significant security incident involving this Twitter account was prevented thanks to our adherence to security best practices. Here's a rundown of the events: 1/ High-profile accounts like @zksync are frequently targeted, and @Twitter is working tirelessly to ensure the safety of the users. In this instance, an impersonator fabricated their identity and claimed to be an official zkSync representative while contacting Twitter support. 2/

Protocol liveness is @zksync's second top priority after security.

We want to share, with full transparency, the details of this incident with our community. Here's an overview of what happened, the reasons behind it, our response, and future plans to prevent liveness issues. TL;DR:

1) Fix took 5 min.
2) Monitoring significantly improved.
3) Please remember, Era is in Alpha.
4) Decentralizing the sequencer is the long-term solution.

Account abstraction is a major leap forward for the Ethereum community. zkSync Era builds upon the vision of EIP-4337 by implementing AA at the protocol level. Let’s explore the differences between EIP-4337 and zkSync Era’s native account abstraction. #scalingthemission

1/11 Accounts Limitations

End users interact with Ethereum through Externally Owned Accounts (EOAs), and those have limitations:

• Coupled with a signer
• Verification logic is hardcoded in the EVM
• No way to recover a lost account
