Super exciting and big congrats! Excited for the @blocknative & @Deloitte teams! @mcutler is such an awesome person, couldn't be more proud!!! 🎉🎉🎉

which twitter accounts/blogs post about every web3 exploit as they happen? i like the @web3sec_news newsletter but are there any realtime ones?

Seamless crosschain interop isn't coming. It's already here. @cryptomachia demos Presto, an app letting you mint an NFT on @ApeChainHUB w/ funds on @RariChain in one click. No bridging required. This is what Espresso's fast finality enables. Check it out at our @EFDevcon booth.

Ppl at devconnect, how’s the steakkkk?

it's been a while since i've watched some project demos! watching this one, Brew house (cross chain apps) youtube.com/live/BURHaihMAJg

Espresso scales rollups <=> rollups scale Ethereum

Feels like the right moment for this thread with the Robinhood L2 chain just announced. Rollups were first conceived as a "scaling solution" for Ethereum. This framing is wrong imo. It's a new paradigm for the future of Web3 that will win out against monolithic chains (1/8) 🧵

Let’s say you have usdc and you want to deposit into Aave, What is the process like and what tokens get wrapped…. If you are curious, watch the video below to find out why from @alysiatech This is Episode 1 of my video remixing journey with @EspressoSys follow for more🤩

@EspressoSys Team Deck ☕️ Piece 006 Another piece added to the story 🎉 Big shoutout to @alysiatech ,who brings that connecting spark to the team🤩 ***This card’s not the end... got a few ideas brewing around this one for the @composablepod Hope you vibe with it and enjoy🤎

We'll be jumping into a livestream here in 15 minutes to discuss @AcrossProtocol's new model for intent-based crosschain bridging: Across Prime We’ll unpack: • What is intent-based bridging and how does it work? • How Across’s architecture works: relayers, bonding, settlement oracle • What is fair exchange and how is it achieved on Across? • What change does Across Prime introduce? • Why does this improve capital efficiency and security? • Why does the user have to wait two blocks and how protocols like Espresso can help? • Our hot takes and crypto twitter takes Stay tuned 👀

🚨 New ep alert! Are TEEs even real? In this episode, @alysiatech & @ellierdavidson speak with @OrestTa from @t1protocol about ZK proofs, TEEs, L2 security & how these concepts relate to blockchain finality. The conversation (timestamps below!) covers: 👉 @VitalikButerin's recent proposal for a "two out of three" proof system 👉 TEEs, their strengths & vulnerabilities 👉 ZK proofs vs TEE proofs 👉 How t1 uses TEEs restaking periodic ZKPs 👉 How this all relates to L2 security & finality Timestamps: 1:00 - skip the intro & dive straight in: Ellie introduces @VitalikButerin's 2/3 proof proposal and the episode's guest, Orest from t1 2:29 - Orest shares his experience as an early engineer at @Scroll_ZKP 3:58 - Why ZK rollups haven't succeeded at scaling Ethereum 5:25 - Orest and @kisaguncan, former co-founder of @SecretNetwork, launch t1 protocol to use TEEs to prove rollup integrity 6:24 - What is a TEE? (long explanation) 10:29 - What's a TEE? (concise explanation) 10:59 - How is t1 using TEEs? 12:32 - Remote attestion & why it's a misunderstood term 16:50 - Vitalik's blog post that proposes using a 2/3 proof system (ZK proofs, TEE proofs, optimistic proofs) and proof aggregation to increase security 19:00 - Why aren't ZK proofs enough? 20:29 - Difference between ZK proofs and TEE proofs 28:18 - Side-channel attacks and potential vulnerabilities in TEEs 32:03 - Using TEEs for integrity rather than confidentiality 38:05 - Centralization challenges & security benefits of multiple TEE vendors 41:10 - Mention of projects like Autonomous TEE from 42:35 - Back to Vitalik's post & how t1 uses TEEs cryptoeconomic security periodic ZKPs 44:50 - t1's use of restaking 49:43 - Closing thoughts on TEEs and their future use in crypto

Just shipped the Across Prime paper, a new design for a capital efficient trustless fast bridge authored with @danrobinson, @mrice32, and the @AcrossProtocol team. Across Prime aims to deliver the near instant speed of intent based bridges but with greater capital efficiency. 🧵

These nail designs by @siannie go so hard!!!

"Sequencer, what big teeth you have!" Great talk by @charleslu1 @token2049 about interoperability and reorgs. @linkpoolio is a proud to supporter of @EspressoSys

Orest (@OrestTa) spilled all the tea about TEEs this morning with @ellierdavidson and I! Can’t wait for this episode of @composablepod to drop next week!!! Which types of L2s achieve the fastest finality whilst being sufficiently secure & decentralized?

"Oh, have a problem with your design? Just throw a TEE in there!" 😂 New episode about to drop. @alysiatech & @ellierdavidson discuss how crosschain messages are secured... yes, including with TEEs

Who Secures Crosschain Messages? Dive in w/ @alysiatech & @ellierdavidson as they explore this topic: 01:08 - Focus on crosschain message security 01:24 - Analysis of the Ronin bridge attack 03:25 - Discussion of the Wormhole attack 07:26 - Overview of the Orbit bridge attack 10:22 - Anatomy of a crosschain message 11:37 - Key vulnerabilities in crosschain messaging 12:33 - Multisig security approaches & trust assumptions 15:26 - Analysis of multisig effectiveness & limitations 17:06 - Practical considerations of multisig implementations 19:57 - Liveness issues in multisig systems 21:11 - Introduction to TEEs 22:13 - How TEEs verify crosschain messages 23:17 - Limitations of TEE security approaches 24:57 - Comparison of TEE & multisig security models 28:20 - Discussion of potential improvements to security models 29:45 - Brief mention of ZK proofs as an alternative approach

I couldn’t agree with her more! Name some apps/protocols that are solving this cross chain friction I’ll start: - Hyperlane - LayerZero - Espresso - Across Protocol - … This clip is from last week’s episode on @composablepod with @ellierdavidson featuring @edatweets_ :)
