一种用于去中心化商业的激励相容智能合约

An Incentive-Compatible Smart Contract for Decentralized Commerce

Nikolaj Ignatieff Schwartzbach

AI总结:

提出一种区块链智能合约作为托管,允许互不信任方交易非数字商品,通过博弈论证明在仲裁者偏向诚实方时诚实策略安全,并推广至多方交易以摊销费用。

摘要:

我们提出了一种智能合约,允许两个互不信任的当事方通过在区块链上部署智能合约作为托管来交易任何非数字商品或服务。该合约通过让各方下注他们能说服仲裁者相信自己是诚实方来解决争议。我们将该合约作为扩展式博弈进行分析,并证明当且仅当仲裁者偏向诚实方时,诚实策略在强博弈论意义上是安全的。通过放宽安全概念,我们可以用随机抛硬币来取代仲裁者。最后,我们展示了如何将该合约推广到多方交易中,从而摊销交易费用。

英文摘要:

We propose a smart contract that allows two mutually distrusting parties to transact any non-digital good or service by deploying a smart contract on a blockchain to act as escrow. The contract settles disputes by letting parties wager that they can convince an arbiter that they were the honest party. We analyse the contract as an extensive-form game and prove that the honest strategy is secure in a strong game-theoretic sense if and only if the arbiter is biased in favor of honest parties. By relaxing the security notion, we can replace the arbiter by a random coin toss. Finally, we show how to generalize the contract to multiparty transactions in a way that amortizes the transaction fees.
