Some quick theorycrafting of how much data space we can save by improving compression (especially in rollups).
ERC4337 signature aggregation ( https://t.co/wFJI3BEq6g ) is essential to this.
But wait paddy mcpat.
What about the watchers and the veto?
The bug is in the process() function which the second step of the protocol.
It bypasses the update() function and entire watching/ veto step.
There was no way to stop it. A dumb init()/solidity bug.
I’ve spent some time working out the @nomadxyz_ hack from my mobile phone.
It is a simple solidity bug. Nothing to do with the design of the bridge.
h/t @ethlorenz for helping me work it out
Let’s dive into it 🧵👇
We really went from Bridge Wars to Bridge Hacks. So far it’s been Nomad, Axie Infinity, Wormhole, Harmony, Poly Network and Multichain. Now all eyes are on other bridges be it Avalanche, Polygon, Stargate, Rainbow bridge if they are safe.
1/ Nomad just got drained for over $150M in one of the most chaotic hacks that Web3 has ever seen. How exactly did this happen, and what was the root cause? Allow me to take you behind the scenes 👇
How does Scroll work - The Architecture Overview
In this post, we take a deeper dive into Scroll’s overall architecture, which in it's initial state is composed of a centralized sequencing node and decentralized proving network.

#ethereum roadmap
- Merge to proof of stake Sept 19th
- Surge - bringing in higher transaction numbers via sharding in 2023
Next three are "sometime later"
- Verge optimise data storage
- Purge rid chain of old data
- Splurge series of small upgrades to help ETH run smoothly
Hybrid idea: optimistic + ZK, governance only adjudicates bugs between the two
1. Publish block
2. Wait 24h for fraud challenges.
3a. If no challenge, publish ZK SNARK, finalize.
3b. If there is a challenge, decide based on 2-of-3 of (challenge game, ZK SNARK, governance)
This chart is awesome, its a TVL-weighted median of APY, so it calculates something like the "average" APY across all defi
