I'm joining Ethlabs @ethlabs_org, a new R&D lab to grow Ethereum and ETH. The network and the asset are entering a new age of adoption, and this is a shift we cannot miss. More capital is coming onchain, both institutional and retail, through the portals of DeFi, stablecoins,

I wrote up a detailed explanation of the 7-block re-org that occurred last week on the beacon chain. It goes over the basics of the PoS Ethereum consensus and shows visually how the re-org happened, and why it is not inherent to the protocol

EIP-1559 is going live today! I am very excited to see all the work that went into it come alive 😀 And among all the excitement for the burn, I wanted to share a little more about why this mechanism is in place

Launching today "RIG Open Problems" (ROPs), a collection of problem prompts we're looking to solve with *you*! 🌱 The prompts come with some questions to answer, but could lead to more open-ended explorations.

Let's bring fast finality asap to @ethereum ! We published an update on our related work and projects last Friday, and on this topic, these are the relevant points: - Shorten slot times to increase the heartbeat of the network and decrease every delay: Time to inclusion / fast

The only serious technical argument in this post is fast L1 finality—something we as L2s can neither fix nor mitigate. We fully depend on the L1 progress rate here. I'd told @ethereumfndn leadership earlier in summer that's the ONLY thing we care about on the ETH roadmap.

I wrote a new post about rollup economics. This framework hopefully provides more clarity on the various parties co-existing in a rollup system, and helps guide discussions on fees and economic designs

While thinking about PBS, I came upon the possibility of unbundling its market structure (proposer/builder anti-griefing mechanisms) from the shape of its allocation mechanism (the whole block auction). Here is a post exploring this alternative!

Shortening the Ethereum L1 slot time from 12 to 6 seconds has benefits across the stack: * Better UX * More value for users, with lower fees on DEXes * A better confirmation engine for interop protocols * More! We make the case for its headliner consideration in Glamsterdam.

Some news! I joined @ethereum as a research scientist in a new team, the Robust Incentives Group. We will look at mechanism design and protocol security from an algorithmic game theory/economics point of view. Excited to share our work soon!
