摘要

区块链用耗时的共识协议取代了中央交易方来记录所有权的转移。这种结算延迟会减缓跨交易所交易，使套利者面临价格风险。相反，链外结算会让套利者面临代价高昂的违约风险。我们利用比特币网络和订单簿数据表明，跨交易所的价格差异与高结算延迟、资产流动追逐套利机会的时期相吻合，而违约风险低的交易所之间的价格差异较小。因此，基于区块链的交易面临两难境地：可靠的共识协议需要耗时的结算延迟，从而导致套利限制。要规避这种套利成本<italic>只能</italic>通过重新安装可信中介来减轻违约风险。

Building Trust Takes Time: Limits to Arbitrage for Blockchain-Based Assets

A blockchain replaces central counterparties with time-consuming consensus protocols to record the transfer of ownership. This settlement latency slows cross-exchange trading, exposing arbitrageurs to price risk. Off-chain settlement, instead, exposes arbitrageurs to costly default risk. We show with Bitcoin network and order book data that cross-exchange price differences coincide with periods of high settlement latency, asset flows chase arbitrage opportunities, and price differences across exchanges with low default risk are smaller. Blockchain-based trading thus faces a dilemma: Reliable consensus protocols require time-consuming settlement latency, leading to arbitrage limits. Circumventing such arbitrage costs is possible <italic>only</italic> by reinstalling trusted intermediation, which mitigates default risk.
