  • Found the most boring pod in bitcoin

    If you want to hear two guys rattle off ‘news’ about companies nobody cares about, this is your pod. Some company acquired another company - snooze. Another company raised some money - zzzzz. The hosts even sound half asleep, how is anyone else supposed to find this drivel interesting.

  • What happened to you being vocal about the “bad boys”??

    The way you’ve flipped the pancake on the bad actors in your industry and inability to call out the grift going on by the White House is hugely disappointing. CZ gets pardoned and you call this “controversial”?? Your listeners have longer memories.

Talking Points

Recent interactions between the hosts and their guests.

Brandon Arvanaghi (Meow) on Banking AI Agents (EP.715)
Q: What was the hardest part about just building out the product for the AI agents? Were there obstacles? How are agents different than humans in that respect?
The main challenges were prompt engineering and understanding the black-box behavior of models, which required heavy experimentation and close collaboration between engineers and AI systems to achieve reliable agent interactions and safe banking operations.
Dana Syracuse and Josh Boehm (Paul Hastings) on the regulatory picture post-Genius (EP.705)
Q: Josh, what should entrepreneurs be thinking about as Genius rulemaking unfolds?
Josh emphasizes that startups should prepare for rulemaking by aligning with capital, AML, sanctions, and governance standards, while evaluating how stablecoin provisioning will adapt to the evolving framework and the potential for various charter types.
Dana Syracuse and Josh Boehm (Paul Hastings) on the regulatory picture post-Genius (EP.705)
Q: Dana, starting with you, what type of companies are going this OCC path?
Dana explains that many firms are applying for OCC charters to enable banking-like activities for custody, purchase-sale of digital assets, and the use of a robust regulatory framework; she also notes that the environment has shifted toward seeking a clear set of rules.
Bhavin Vaid (Birch Hill) on Better Markets for Tokenized Assets (EP.700)
Q: What advice would you give to potential asset issuers of financial institutions who might be thinking about issuing an asset on-chain?
Vaid emphasizes the importance of efficiency within the asset issuance process, suggesting that institutions should focus on streamlining their operations rather than adopting practices that could lead to negative outcomes for retail investors.
Corn (Yearn Finance) on the Evolution of DeFi Protocols (EP. 691)
Q: What's the role and maybe the faults of the risk curators in some of these scenarios?
Corn explains that curators need to manage the risk within vaults, ensure sound collateral, and adapt to market demands, despite the overall business being challenging due to low profits.
