OKP4 (Open Knowledge Protocol For) is a revolutionary public blockchain protocol where communities are incentivized to share data and services confidently. To maximize value from data, it needs to be processed by complex algorithms and pooled with other datasets, to create valuable knowledge. In other words, data must be shared to maximize its value. OKP4 is a layer 1 where anyone, any group, any company, can join or create a Data Space with customed rules, governance mechanisms and business models to maximize value from data without any trusted third party. OKP4 is built on the Cosmos SDK and is designed to become a vibrant hub of data providers, communities of developers, data scientists & users for synergies and maximal value creation. Several use cases and partners across many industries allowed us to test the protocol in a testnet. Our mainnet and token launch is scheduled for Q1 2023.
