Blockchain relay schemes rely on off-chain clients constantly submitting block information from a source block-chain to the relay running on a destination blockchain. As clients incur costs when submitting block headers, an incentive structure needs to be in place that compensates clients for their efforts.
In this paper, we develop an incentive structure for blockchain relays that follow a proof on demand approach where block headers are optimistically accepted and only fully validated if identified as illegal by off-chain clients. The preliminary cost analysis shows that such blockchain relays are able to drastically reduce operational costs over relays that validate every single submitted block header.
