Every Bitcoin Layer 2 quietly depends on a trusted operator to order transactions and that's the single point of failure Jeremy Rubin wants to kill. In this MIT Bitcoin Expo conversation with Bitcoin Magazine's Shinobi, Rubin breaks down Char Network, a decentralized shared sequencer that lets anyone participate like a miner. He explains how staked Bitcoin gets burned the moment a participant cheats, and why anchoring proof of stake to Bitcoin avoids the pitfalls of standalone PoS chains.
