Incentive Non-Compatibility of Optimistic Rollups (2312.01549v3)
Published 4 Dec 2023 in cs.GT and cs.CR
Abstract: Optimistic rollups are a popular and promising method of increasing the throughput capacity of their underlying chain. These methods rely on economic incentives to guarantee their security. We present a model of optimistic rollups that shows that the incentives are not aligned with the expected behavior of the players, thus potentially undermining the security of existing optimistic rollups. We discuss some potential solutions illuminated by our model.
