1/19 At EthDenver, people keep asking me on my perspective on optimistic rollups vs zkRollups. Unfortunately, zkRollups have managed to occupy the whole narrative space, so here's a take that is a bit more nuanced!
I think the mempool is going to be one of the next blockchain module where we will see a lot of innovation.
Encrypted mempools, side-pools, app-specific mempools, custom appchain mempools, ... read all about it below!
1/35 🧵 I think most people understimate the potential of smart contract wallets (aka account abstraction).
Yes, social recovery, gas subsidies and stablecoin gas are all cool ...
... but what excites me the most is *delegation*.
1/27 🧵 The chain/rollup-as-a-service field is furiously heating up right now.
I count no less than 9 dedicated companies that want to compete in the space (not even counting L2s and L1s that may want a part of the action). Here's a whirlwind tour!
Who's ready for a showdown 🤠 ???

(Actually a really nerdy & detailed breakdown of differences — fooled ya)

Ethereum engineering puzzle 🧩
You're writing a backend service that has to submit transactions to the chain using an in-memory private key. You might need to submit multiple transactions on the same block, and retry them if they don't land.
Pause here — do you already see an
It's funny seeing this new wave of Ethereum-killers (or should I call them Solana-killers?) coming out (Sui, Aptos).
It feels like a fundamental mistake. Why make an L1 that nobody can validate when you can have an L1 (ETH) you can + validity proofs or fault proofs?
I think the OP stack is good, I'm proud of my part in it, and I'm happy it's as successful as it is.
But let's stay honest: it's not very modular besides swapping the execution engine, and modularity wasn't a big design goal during my time at OP.
We built the OP Stack to be the most forkable, modular scaling infrastructure out there.
That bet on community is paying off: it feels like every other day someone gives the OP Stack a new superpower, or launches a new chain. 🥞🦸♂️✨
But the story doesn’t end there.
It doesn't matter what your intention is. It remains the case that these copyrights can be used offensively.
And what you consider defense, not everybody might agree with.
ZK belongs to everyone.
Rollup-as-a-service (RaaS) providers are a topic that comes up often in my conversations. I wanted to share some thoughts on the topic!
I’m afraid that RaaS providers are very misaligned with their customers at the moment.
I’m excited about a future of many networked rollapps.
