The Chopping Block: Corpo Chains, Monero’s AI Vampire Attack, and DAT Mania - Ep. 887

Altcoin season meets corporate blockchains as Circle and Stripe launch their own L1s, Monero suffers the biggest 51% attack in history (powered by an AI named “Garth”), and the crew debates whether the DAT boom is heading toward equilibrium or mania. Welcome to The Chopping Block – where crypto insiders Haseeb Qureshi, Tom Schmidt, Tarun Chitra, and Robert Leshner chop it up about the latest in crypto. In this episode, the crew dives into the surprising altcoin rally and asks whether ETH still counts as an alt. The big news: Circle unveils Arc, Stripe leaks Tempo — and crypto Twitter is not impressed. We explore why major fintechs are launching their own chains instead of using Ethereum L2s, and whether stablecoin-centric blockchains are the future or just profit grabs. Then: the wildest headline of the week — Monero gets hit with a 51% attack by Qubic, a project training an AI called “Garth,” in what might be the largest attack of its kind. We break down the game theory, the proof-of-work vs. proof-of-stake debate, and what this foreshadows for Bitcoin’s security decades from now. Also: Trump’s executive order opens the door for crypto in 401(k) plans, we speculate about a future GPU debt market crisis, and dissect the state of play in Digital Asset Treasuries (DATs) — including whether yield advantages over staking ETFs mean we’re only halfway to mania.
