🚨 New ep alert! Is the FUD even real? In this episode, @alysiatech & @ellierdavidson tackle Ethereum FUD head-on with the assistance of an "Ethereum FUD" die (a special piece of swag that @EspressoSys handed out at ETHDenver). They discuss fee structures, parasitic L2s (or not), fragmentation, and Ethereum's overall direction, separating valid criticism from misconceptions and providing a balanced take on Ethereum's current challenges. Timestamps: 01:45 - Fees Too Low 08:05 - Parasitic L2s 14:00 - Fragmentation 23:00 - No North Star 31:55 - No Marketing 42:00 - L2s Are Multisigs 50:00 - Fees Too High 56:00 - MEV Centralization & Builder Censorship 01:07:00 - Beam Chain 2029 01:12:00 Closing Thoughts

Ellie spotted 👀 ...and with the Parthenon in the background!
Thanks to all the wonderful people who attended the first edition of Interopolis! Closing sessions starting now with takeaways from the Crosschain composability session with @ellierdavidson & @OrestTa.

New ep drops Thurs about intents & Across Prime, a design from the @AcrossProtocol team for a fast, capital efficient bridge. in this clip, @alysiatech points out an important, but overlooked, user of intent bridges are relayers themselves (ie, the parties that fulfill intents)

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?

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

How trustworthy are ZK proofs? In the new ep, @OrestTa from @t1protocol joins @alysiatech & @ellierdavidson to discuss this topic, as well as dive into TEEs and @VitalikButerin's recent proposal for a "two out of three" proof system to enhance L2 security while improving finality times. Full ep coming soon!

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_ :)

Intent-based systems simplify crypto UX by ditching "here's how to do it" in favor of "here's what I want done" Join our livestream in ≈15m w/ @edatweets_ from @hyperlane—she'll unpack intents & share how to build w/ the Open Intents Framework Send us your intents-related Qs!
