🚨 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.

Closing sessions starting now with takeaways from the Crosschain composability session with @ellierdavidson & @OrestTa.

[Composable 🧩 @composablepod]

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)

[Composable 🧩 @composablepod]

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

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

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!
