Simplicity Comes To Liquid with Andrew Poelstra | SLP686 Andrew Poelstra, Director of Research @blksresearch @blockstream joins me to discuss Simplicity's launch on @Liquid_BTC — a federated sidechain of Bitcoin. From advanced covenants to ZK proofs, stablecoins to capital markets, we explore how this new scripting language boosts expressivity & security, and why Liquid’s vision differs from Lightning. (00:00) - Intro (01:57) - What is Liquid? (04:36) - What is Simplicity?; Enhanced expressivity on Bitcoin (11:48) - Implications of ‘formal verification’ for developers building on Liquid and Bitcoin? (17:00) - What does Simplicity enable people to build? (18:59) - What is a Sighash flag? (28:35) - Could Shielded CSV be built using simplicity? (33:32) - Zero Knowledge proofs verification with Simplicity (43:15) - Use cases of Simplicity: Limit orders and Algorithmic trading in DeFi (51:18) - Liquid's role in asset issuance and capital markets (56:55) - Liquid vs. Stablecoins issuing their own Layer 1 chains (1:02:22) - Liquid vs. other Layer 2 solutions (1:07:53) - Closing thoughts; Developer engagement with Simplicity
