Paul Sztorc

Definition: Paul Sztorc is a Bitcoin researcher who created Drivechain (BIP-300 and BIP-301), a proposal for enabling permissionless Bitcoin sidechains through a mechanism called “blind merged mining,” and Hivemind (formerly Truthcoin), a Bitcoin-backed decentralized prediction market protocol.

Key Contributions

  • Invented Drivechain (formalized as BIP-300 and BIP-301), a Bitcoin soft-fork proposal that would allow arbitrary sidechains to be secured by Bitcoin miners without requiring trust in a federation
  • Drivechain uses “blind merged mining” — miners can simultaneously mine Bitcoin and any number of Drivechain sidechains without any additional computational work
  • Created Hivemind (originally called Truthcoin), a proposal for a decentralized prediction market using Bitcoin as a trustless oracle and settlement layer
  • Has been one of the most organized and persistent advocates for adding programmability to Bitcoin via sidechains rather than changing Bitcoin’s base layer
  • Maintains LayerTwo Labs, a company working on implementing and deploying Drivechain

Timeline

  • 2014 — Published the Truthcoin whitepaper, proposing a Bitcoin prediction market.
  • 2017 — Formalized Drivechain as BIP-300 (hashrate escrows) and BIP-301 (blind merged mining).
  • 2019–2022 — Continued advocacy for Drivechain; built testnet implementations.
  • 2022 — Founded LayerTwo Labs with Tierion founder Wayne Vaughan to fund Drivechain development.
  • 2023 — Drivechain became contentious discussion among Bitcoin Core developers; mailing list debates.
  • 2024 — Ongoing Drivechain testnet activity; BIP-300/301 not yet merged into Bitcoin Core.

Controversies

  • Bitcoin Core resistance — Drivechain has been consistently rejected by the Bitcoin Core developer community, which argues it introduces security risks and governance complexity. Critics claim miners could collude to steal sidechain funds. Sztorc disputes this.
  • Prediction market legality — Hivemind/Truthcoin raises legal questions about unlicensed prediction markets in multiple jurisdictions.
  • Disagreements with Core devs — Sztorc has been publicly critical of Bitcoin Core maintainers for what he sees as excessive conservatism in not even testing Drivechain.

Social Media Sentiment

Sztorc has a dedicated following among Bitcoin sidechain proponents and those who believe Bitcoin’s functionality should expand without base-layer changes. He is known for careful, long-form arguments rather than social media rhetoric. Bitcoin maximalists who oppose any change to Bitcoin’s base layer or miner role are skeptical; some are openly hostile to Drivechain.
