Some of the most impressive technical and commercial leaders in digital assets emerged from what insiders call the "Libra Mafia" — the team assembled by
@Meta to build Libra (later Diem).
Though the project ultimately succumbed to regulatory pressure, it produced a generation of founders and engineers who went on to shape the industry, including Sam Blackshear (
@b1ackd0g), a leading expert in blockchain programming languages and CTO of
@Mysten_Labs
In this episode of Bitcoin Rails, Sam joins me to discuss:
- Why Mysten Labs has turned its focus toward Bitcoin why Sam leans conservative on soft-fork changes to Bitcoin script
- What makes a strong crypto programming language why EVM is missing the mark
- Why trust minimization remains the critical technical challenge standing between Bitcoin and broader DeFi adoption
- Why Mysten Lab's new Hashi architecture may be the most trust-minimized architecture for Bitcoin "bridging" without a soft fork
