Abstract

Publica’s protocol for decentralised publishing on the
blockchain is a reinvention of Gutenberg’s press for
the 21st century. Even if it becomes a de-facto largest
publisher, it maintains no inventory. Nonetheless, the
books that it publishes can last forever, both for the
readers who own them and for the world.

A book’s access keys are represented by an Ethereum
ERC20 token that Publica calls the READ Token, unique
to each literary work. A READ Token balance is mapped
to the public key of its owner in Ethereum’s programming
language called Solidity. Decentralised free access to
the Ethereum blockchain’s data enables transparent
verification of ownership. It also enables decentralised
authorization of access to the literary work that any
given READ Token is associated with.

The operational protocol layer is built in Solidity and
uses the Ethereum network’s computing power. It
processes direct transactions in the protocol’s currency
between readers and authors (buyers and sellers) for a
book’s access keys.

Literary works will be stored in decentralised immutable
storage built on top of continuously advancing solutions
for decentralised immutable storage. Publica protocol is
experimenting with solutions offered by IPFS, Storj, Sia,
MaidSafe and upcoming Filecoin, EOS and eventually,
Swarm for Ethereum.

Publica’s protocol is powered by its currency called
Pebbles (PBL ticker, an ERC20 token), issued in a fixed
and locked supply.

The protocol’s application layer of customer-facing apps
will be built by the protocol team as white label, open
source tools available to the community for branding,
extending, and embedding into other applications, to
enhance current ink-readers and e-readers with a walletmodule
supporting Publica’s protocol.
