Peter Todd and Space Pirates, Open Timestamp, Proof Martial - Baltic Honeybadger 2018 Conference

## Baltic Honeybadger 2018 Conference Podcast Summary: Peter Todd & Emerging Technologies

This podcast episode, recorded at the Baltic Honeybadger 2018 conference, features a wide-ranging discussion primarily led by Peter Todd and Max, exploring the potential of Bitcoin and related technologies to revolutionize various industries. The conversation began with humorous speculation about the future of Bitcoin mining in space, highlighting concerns about the slow pace of Mars colonization efforts led by Elon Musk and jokingly suggesting the need for a "Mars coin." This playful introduction quickly transitioned into serious discussions about the limitations of current systems and the potential for decentralized solutions, particularly focusing on the role of open timestamps and innovative data structures to replace traditional notaries and improve data security. The conversation then delved into complex technical concepts, exploring the challenges of maintaining consensus in isolated environments and the implications of advanced physics (like time dilation near black holes) on blockchain functionality. Ultimately, the discussion underscored Peter Todd's commitment to leveraging Bitcoin’s strengths while acknowledging the practical complexities of real-world implementation.

Main Topics Discussed:

• Space Pirates & Mars Coin: Humorous speculation about Bitcoin mining in space and the potential need for a specialized cryptocurrency for Martian settlements.
• Open Time Stamps: Peter Todd’s project to replace traditional notaries with a decentralized, software-based solution leveraging Bitcoin’s timestamping capabilities.
• Proof Martial: A project aimed at creating data structures that chain blockchain commitments back to Bitcoin for consensus, addressing the problem of proving data non-existence (e.g., preventing double-selling of property).
• Single Use Seals: A concept within Proof Martial, drawing an analogy to shipping container seals, to ensure data uniqueness and prevent double-spending.
• Securing Blockchain Data with Bitcoin: A system where blockchain data is secured by linking it to Bitcoin transactions, allowing verification without altering the Bitcoin protocol.
• "Sign to Contract" & Data Minimization: A cryptographic technique to commit to data with minimal data included in Bitcoin transactions.
• Scaling Solutions: Discussions around layered blockchains and the use of “Miracle Trees” to handle high transaction volumes.
• Time Synchronization & Consensus: Exploring the challenges of maintaining timekeeping in isolated environments and the implications of relying solely on block time for consensus.
• Private Key Control & Legal Systems: Addressing the practical considerations of private key management and how legal systems might handle lost keys.

Key Quotes:

• Peter Todd: "I'm very disappointed at the rate of progress on Elon Musk's Mars missions..."
• Peter Todd: "It's much easier to come to consensus when we just have the sun peering down on us."
• "Well, if you can't trust people who are falling into a black hole, who can you trust now?"
• "Well, what does proof martial do? It automates a process of getting that data."
