🚨 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

🚨 New ep alert! Are intents even real?

Ellie spotted 👀 ...and with the Parthenon in the background!

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)

Are Intents Even Real? x.com/i/broadcasts/1…

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

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!

- The Composable Podcast🧩 In the latest Composable Episode, @alysiatech and @ellierdavidson dive into an engaging discussion about wrapped tokens - exploring their fundamentals, benefits, challenges, and how they differ from canonical tokens. x.com/composablepod/…

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!
