Hoping someone can explain the differences between Fusions DCRM technology and Interledger in regards to interoperability.
From my reading of the paper (I only skimmed it so take this with a grain of salt), it looks like Fusion is a protocol for synchronizing transactions across multiple blockchains by creating a group of nodes that multisigns transactions and submits them to the chains you want to send between.
This is very different because Interledger occurs on a level of abstraction above the underlying settlement network. An entire Interledger payment can occur without any “real funds” moving on any underlying payment networks.
Put more generally, Interledger’s purpose is to allow really fast transactions between two parties who don’t have a trust relationship. Fusion’s purpose appears to be synchronizing Blockchain transactions.
