Publica is a decentralized publishing system based on the blockchain technology. It is a reinvention of the Gutenberg press for the current century. The access keys to Publica are represented through the Ethereum ERC20 token - READ. The token is configured to be a public key and in its core is a programming language also called Solidity.The Ethereum blockchain enables completely transparent ownership-verifications. The operating protocol-layer is designed to be built into the Solidity program itself and is exclusive only for Publica. It processes direct transactions from start to finish and keeps the connection between readers and authors stable at all times.Publica’s specific protocol is powered up by another ERC-20 PBL ticker token, called Pebbles, which are issued into a fixed, limited and locked supply.
