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

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🤎
Piece 005 just dropped🎉
Sharing another @EspressoSys Team Deck moment☕️
This one’s for @vezzabel 👑
Made with the same love and creative energy behind it all.
Every card tells a story, but this one is one of my favorites so far🤩
Hope you vibe with it too 🤎
Still cooking...☕️

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 @siannieeee go so hard!!!
dubai fomo is so real right now, missing out on my nail design for @SuiNetwork and @chippedsocial 😭
fine, i'll paint my own set but be sure to grab yours at sui basecamp okbye!!

"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?
Alysia 👩💻☕ retweeted
"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

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
- …
