Example Piece: On-chain light client #89

JoshOrndorff commented 1 year ago

I just got back from PBA3 where I gave students an assignment to write a smart contract that works as on on-chain light client for another chain. Basically a btc-relay like thing. We were using solidity and ink! so of course the solutions were all account based. Got me thinking about how to implement the same thing in UTXOs. I think each foreign block header could be a separate utxo.
