Over time, I see a situation emerging in which Bitcoin functions as a kind of uber-anchor for everything. Its role will be to be a kind of ultimate “layer 0” record of truth. Meanwhile, Ethereum and other smart contract platforms could take on higher-level functionality, with each specializing in different types of transactions and data-processing that the rather clunky, limited-function Bitcoin blockchain is not built to perform. It will need greater cross-chain operability, but there are plenty of people working on that.
