Outcome
Overview
We (1) improve computation by 2 orders of magnitude in Ethereum by making minor protocol changes, (2) reduce confirmation latency using novel entities called Anchors and Links, (3) improve computation in Ethereum by factor of 2 by leveraging redundancies in computation without modifying the protocol. As future work we are studying sharded permissionless systems.
