can't wait for the second video 😂
We spent $200,000 hiring an actor for 3 hrs of his time. This better be worth it.
Last week I reported a Critical bug to @Scroll_ZKP via @immunefi. Massive shoutout to the team for their exceptional commitment to security. The issue was mitigated within minutes after the report. Glad to contribute to Scroll and the Ethereum ecosystem 🧙♂️📜
3/ Issue 2: Bridge Message Spoofing A separate bug (reported by @WhiteHatMage via @immunefi) could have allowed attackers to mint ETH or ERC20 tokens on Scroll by spoofing messages across L1 and L2. This vulnerability came from a change introduced during the Euclid upgrade.
Big shout-out to @WhiteHatMage and @axiom_xyz for responsibly disclosing critical vulnerabilities. Kudos to the @Scroll_ZKP team and the Scroll Security Council for the swift response and seamless emergency upgrade. 🙌
1/ Last week, Scroll performed an emergency mainnet upgrade to fix two critical bugs - one in our zk proving system and one in our bridge contract. Here's a breakdown of what happened, how we acted to protect users, and what we plan to strengthen security moving forward. 🧵
Achieving Stage 1 as the first zk-rollup wasn’t easy. It’s the results of many technical advancements and thoughtful protocol designs coming together. If you want to dive into the work behind the scenes that made it possible, check out this article.

Euclid is LIVE: Scroll's biggest upgrade since mainnet launch begins today! We've successfully deployed the first part of this comprehensive 7-day upgrade process, bringing major improvements to Scroll's infrastructure. Here is everything you need to know ⬇️
Euclid Phase-1 hardfork completed smoothly ~1 hour ago at block height 14785107. Scroll Security Council is now validating the zkTrie → MPT migration. Mainnet finalization is expected to be delayed by ~24 hours. Meanwhile, you are all welcome to join the verification effort
The Euclid Phase-1 hardfork will happen on Scroll mainnet at 15:00:00 UTC, April 16 (~17 hours from now)! This upgrade transitions Scroll's state trie from zkTrie to Ethereum’s MPT, enhancing dapp compatibility and sequencer performance. Due to the significance of this update,…

We need a truth terminal for Trump's administration
Trump says no tariff “exception” was announced on Friday
Are you tired of centralized L2s 😴? Yeah, me too. 😡 But @Scroll_ZKP 📜, a zk-rollup layer-2 solution, just dropped a game-changer with its Euclid upgrade—and it’s about to become the first stage-1 zk-rollup in history! 🚀 Let's dive into all of that 🏊♂️ TL;DR 🥱 - Rollup…
The Euclid upgrade proposal just passed the voting. It means that in 2 weeks - @Scroll_ZKP will become the first stage-1 zk rollup - >2k TPS with sub-cent tx fee - upgrade to zkVM prover @openvm_org - support EIP-7702 and RIP-7212 - migration to MPT for more compatibility…
Last week, Scroll Sepolia underwent its biggest upgrade yet, transitioning from Halo2 to a zkVM. I want to take a moment to highlight the broader benefits of zkVM for the entire technical community. Until now, deploying a custom zkRollup has been nearly impossible for small…
ZK is the endgame for blockchain scalability. Blockchains are built to eliminate the need for trust. But there are two fundamental bottlenecks for this: information propagation and verification. In PoS systems, validators must download and re-execute every transaction to…
