will present our interesting work this Thursday. If you will also be there, feel free to DM me :)
Obfuscating contracts can hide bugs rather than enhance security. @syang2ng, PhD student at @Yale, will speak at DSS on “Insecurity Through Obscurity: Veiled Vulnerabilities in Closed-Source Contracts”, presenting SKANF, a tool that reveals hidden bugs and MEV-phishing risks.

both CTF and analysis are interesting 😆
Just saw @0xkaden publish an interesting onchain CTF. The money was gone, but I wanted to walk through it so my followers and students can see how to approach these challenges.

very impressive post
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.

best one slider problem statement of geo decentralization i have ever seen s/o @boez95 for making them ... so much great stuff coming out of flashbots research and others on this, very excited

Geography is destiny. Public blockchains like Ethereum were built to transcend borders. Yet if you plot where their validators actually run, the map tells a different story — dense clusters around...
Decentralization underpins permissionless blockchains, but what about geography? 🌍 Our new study explores this often-overlooked dimension of crypto. (1/n)

Phil's 2023 post, "Decentralized crypto needs you: to be a geographical decentralization maxi," urged us to put more emphasis on studying this phenomenon, which is a cornerstone for building global permissionless systems — this research continues in that direction. 🫡

Decentralized crypto needs you: to be a geographical decentralization maxi In this post, we take a look at trends in MEV that we believe have the opportunity to centralize and weaken the core mission...

We released our simulation tool ( https://t.co/lWovslB0Pw) 🛠️ and a visualization frontend ( https://t.co/JXidxuulBO) 📊 to explore the results. Still improving — feedback welcome! (7/n)

We also test alternative Ethereum consensus settings: - 6s slot times: amplified reward asymmetry across regions ⏱️ - Higher/lower attestation threshold: degree of centralization depends on protocol… 🤔 (6/n)

Key takeaway 💡 SSP — similar to PBS — can enable more even access to value across validators in different regions, provided that information sources, such as relays, are strategically placed. Without PBS (i.e., MSP), validators must aggregate value themselves, making location

We develop an agent-based simulation framework to study Ethereum's geo-decentralization under two block-building paradigms 🏗️ : - Multi-Source Paradigm (MSP): validator aggregates information distributed across regions to locally build and propagate the block - Single-Source

But protocol design can influence how important the latency edge is, and thus, reshape validator incentives and the geography of (de)centralization. ⚡ (3/n)

It is no secret that Ethereum validators are spread unevenly. Today, they cluster along the Atlantic (EU and US East Coast), where structural latency advantages persist. 🌐 (2/n)

next frontier of MEV 🤑
Stage A: @boez95, Researcher at Flashbots, is on with Cross-Chain Arbitrage: The Next Frontier of MEV in DeFi 🔀 He’s diving into how arbitrage across ecosystems is reshaping MEV, liquidity flows, and the opportunities emerging in decentralized finance.

a great opportunity for anyone interested!!! I am 100% sure that Kaihua and his students will do great work.
Personal update: Thrilled to start as an Assistant Professor at @WarwickDCS @uniofwarwick today! 🌟 If you’re a student curious about research in decentralized systems, blockchain, DeFi, or AI, I’d love to chat. There are plenty of funding opportunities to explore, just reach
