Yet the actual innovation brought about by bitcoin is not the currency itself but the platform, which is commonly referred to as the “blockchain” — a distributed cryptographic ledger shared amongst all nodes participating in the network, over which every successfully performed transaction is recorded.

And the blockchain is not limited to monetary applications. Borrowing from the same ideas (though not using the actual peer-to-peer network bitcoin runs on), a variety of new applications have adapted the bitcoin protocol to fulfill different purposes: Namecoin for distributed domain name management; Bitmessage and Twister for asynchronous communication; and, more recently, Ethereum (released only a month ago). Like many other peer-to-peer (P2P) applications, these platforms all rely on decentralized architectures to build and maintain network applications that are operated by the community for the community. (I’ve written before here in WIRED Opinion about one example, mesh networks, which can provide an internet-native model for building community and governance).
