Publica will be a platform for authors, readers, books of all kinds and the people who make them. And for smart contracts to carry all kinds of transactions and exchanges for the publishing economy.
Publica protocol is powered by its currency called Pebbles (PBL, ERC20 token) that has fixed and locked supply. Protocol app layer of customer-facing apps will be built by the protocol team as a white label, open source tools available to the community for branding, extending and embedding into other applications e.g. enhancing current ink-readers and e-readers with a wallet-module supporting Publica protocol.
