Truthcoin Peer-to-Peer Oracle System and Prediction Marketplace Paul Sztorc1 truthcoin@gmail.com https://github.com/psztorc/Truthcoin 1M5tVTtynuqiS7Goq8hbh5UBcxLaa5XQb8 Version 1.4.1 – 7/10/2015

Abstract. Bitcoin can support financial derivatives and smart contracts, but the main benefits are lost if a trusted third party is required to inform these contracts. Instead, I propose a proofof-work sidechain which collects information on the creation and state of Prediction Markets (PMs). An “oracle corporation” model attempts to guarantee that a group of self-selected, anonymous, greedy users will always resolve contract-outcomes honestly. Users [1] bear all of the economic costs and benefits of any PMs they create (ensuring efficiency), [2] can create PMs on any subject, and [3] can trade anonymously in any PM. All PMs enjoy low fees, permanent market liquidity, automatic token-issuance, and fair, high-speed trading through a LMSR market maker. Scalability and customizability are achieved via ‘branching’ (controlledfork of the VoteCoin set).
