🚨 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

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)
Are Intents Even Real? xitter.cf/i/broadcasts/1ypKdZrzQ…
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

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
- …
