Payment mechanism for, for example: Open p2p messaging protocols on the Internet Open p2p storage protocols on the Internet In other words, Ethereum at its core provides an open p2p consensus protocol on the Internet that provides a mechanism for transferring fractional/units of value between accounts. It can/does provide for much more than that given its Smart contracts facility (supporting critical contract-state changes that also require consensus), but that's the heart of it. Open p2p Consensus + Storage + Messaging == Web3 The base-layer consensus protocol that is Ethereum can be used as a substrate for the economic incentives of other open p2p protocols (i.e. not a blockchain protocols), providing strong guarantees of transaction finality.
