On February 9, 2017, Blocktime team interviewed Paul for miketwenty1 about his path from prediction markets to Bitcoin, Satoshi Roundtable discussions, Drivechain sidechains, Blind Merged Mining, Lightning, eCash, and Hivemind oracle design.

Highlights

Key Takeaways

From Prediction Markets to Bitcoin

Paul grounds his Bitcoin work in an early fascination with Robin Hanson, prediction markets, statistics, economics, and the practical problem of turning social knowledge into tradable signals. His path into Bitcoin comes through seeing real usage and then connecting it to the longer history of cypherpunk money, Chaumian eCash, and Satoshi's peer-to-peer design. That background frames Hivemind as more than a side project: it is part of a broader effort to make Bitcoin support markets for information, coordination, and collective decision-making without relying on fragile website-style custodians.

Drivechain as Practical Sidechain Infrastructure

The Drivechain discussion presents sidechains as a straightforward extension of Bitcoin's existing strengths: lock coins on the mainchain, credit them on a sidechain, and later condense the return path into a carefully checked withdrawal transaction. Paul emphasizes that the core challenge is enforcing the money movement without forcing every Bitcoin node to validate every sidechain. This is the heart of the soft fork design that later maps naturally onto BIP300/301: Bitcoin stays focused while users gain permissionless access to new rules, larger blocks, smart contracts, privacy experiments, and other systems using BTC.

Blind Merged Mining and Bitcoin Coordination

Paul explains Blind Merged Mining as the mechanism that lets sidechain users pay Bitcoin miners to commit sidechain blocks without requiring miners to run each sidechain's full node software. Sidechain operators collect transaction fees, bid for inclusion, and miners include the relevant hash in the Bitcoin coinbase, creating a market for sidechain block production. The interview also connects Drivechain with Lightning, showing them as complementary: Lightning can route across chains, while Drivechain gives Bitcoin a disciplined way to absorb useful altcoin-style experimentation while preserving the mainchain's monetary center.
