> Blockchain is of course much wider than cryptocurrencies This is a weird position. In the sense that the concept of a "blockchain" is not tied to cryptocurrencies, they're really just an old, well-understood data structure (e.g. the Git datamodel is fundamentally a blockchain, except generalised from a linked list to a DAG), and it's neither novel nor the focus of the current craze. In the sense of a decentralised distributed system, the only fully decentralised consensus layer I know of (Nakamoto consensus) literally depends on being used to host a cryptocurrency for its security guarantees.
