There's lots of debate over what market structure will look like with ePBS. I'm bullish trustless payments because a decentralized network shouldn't need to push 90% of blocks through three geographic chokepoints that just facilitate an offchain auction.

truly incredible.

With Quasar now integrated, PropAMMs are quoting in 94% of mev-boost blocks!
We are now live with a @titanbuilderxyz compatible propAMM maker quote update web-socket. Please see our documentation at docs.quasar.win/propamm/make… More to come soon as we start to bring on more market makers and volume!

As of today, BuilderNet supports prioritised updates This means propAMMs and other designs that want to prioritise some calls over others are now feasible This Titan's announcement earlier this week mark the beginning of a new chapter in transaction execution on Ethereum with a whole new set of challenges, opportunities and unknown unknowns (definitely tighter spreads) Making this new market efficient and reducing the need to rely on trusted intermediaries will require a lot of coordination across the ecosystem As a first step, we want landing updates to be permissionless. So we're launching v0 of a registry format we hope will become an industry standard - one where builders don't need to trust the prioritised updater. We've been collaborating with other builders and DeFi teams on this behind the scenes - post coming soon. Landing updates is just the beginning, we're cooking on several related features. Some of them are predictable, some of them are not - stay tuned. Docs in next tweet

Meet 0x841: a fresh sandwich bot lurking in the dark forest--currently attacking about 1500 users per day, while going almost unnoticed. What's particularly scary: most of the victims are using private mempools and should be protected.

These attacks flip the usual competitive dynamics on their head. Traditional sandwiches are low-risk and competitive, with most of the revenue bid away to the proposer. These attacks are riskier for the bot, but face little competition—letting 0x841 keep more of the value.

We need stronger cryptographic guarantees around order flow. Handshakes and legal agreements are not enough. In the short term, that means moving as much as possible into TEEs. In the long term, it means building encrypted mempools that preserve execution quality.

Honestly insane that the hacker felt comfortable enough to swap their stolen funds into USDC to bridge out. What is Circle doing
Hacker was still swapping millions of $SOL to $USDC and bridging out almost 3 hours after the hack lmao

This is great research highlighting a problem This should be a call to mechanism designooors. We don’t want to be stuck in an equilibrium where aggregators are forced to police liquidity providers. That sucks for them and it won’t lead to the permissionless world we’re trying to build IMO the right approach here is just-in-time routing. We’re cooking on it. Other folks are too. Don’t think anyone knows how best to do this though

The price you see isn't always the price you get 🪤 Some liquidity operators are gaming aggregators and traders are paying for it. We're exposing how. Full breakdown in the replies 👇

very important paper about JIT resale of certain auction designs (!!)

1/n Ahead-of-time (AOT) auctions may lead to secondary resale markets. Arbitrum's Timeboost is a live case. We study what happens when such a market actually emerges.

Spicy take: execution quality through LUCID might be worse than getting sandwiched - 6s --> 18s median inclusion time - Higher fees from gas limit pricing - 150M gas of transactions changing pool states leading to huge slippage in routes - Big jump in reverts from the slippage
If I'm doing DeFi on a chain with an "encrypted mempool", does that mean I need to trade based off prices that are 1 block old?

Today, more validators censor OFAC than builders. Builder censorship has gone from over 70% to less than 5% over the past two years.

People just aren't ready for Flashbots to change blockchains e2e. They even used FHE to blindly backrun transactions and created an anonymised mempools. Even outside of crypto, this team is our real shot to complete trustless confidential computing. Onwards 🚀
0/ For years, proponents of blockchain technology and markets have traded off DeFi execution for decentralization. 3 years ago, Flashbots proposed an escape hatch through a Single Unified Auction for Value Expression. But it’s been a while. How about an update? 🧵⬇️

🚨🚨🚨 YOUR METADATA IS LEAKING 🚨🚨🚨🚨 the Internet, Signal, Tor, blockchains, banks, apps, they are all feeding your metadata 🚨 STRAIGHT TO THE SURVEILLANCE COMPLEX 🚨 after skimming every penny they can off the top stop the abuse
ePBS 🤝 BuilderNet 🤝 Anonymous Broadcast People underestimate the future of block building. Soon we'll have fully censorship resistant pre-transaction privacy. No operators will know what's coming until trades land onchain.
