Cool stuff, I have a few questions:<p>- Is DCN a smart contract where centralized exchanges push settlement groups to (say once every x minutes)? This would indeed allow for fast offchain matching while settling onchain. However the CEX needs to feed in all signatures from all traders, resulting in a big bloat nonetheless (ETH blockchain is over 1TB right now).<p>- This would require users to lock funds not just in the DCN, but tell the DCN at what specific exchanges these funds can be spent. If not a user can give 2 exchanges the same signature (to the same funds locked in DCN) and trade the same funds twice.
Its a step in the right direction. I love to see crypto being used to solve these problems. But unfortunately its one very small step in what needs to be giant leaps.
