RChain was the culmination of a number of innovations by founder Greg Meredith. The core of RChain is based on mobile process calculi, a branch of mathematics with approximately 30 years of history. Together with the experience of other blockchains and other technology, the RChain architecture was documented in July, 2016. At that time, the goal was to create a blockchain-based social network with inbuilt micropayments functionality (i.e. attention economy). Due to the complexity of the project and disagreement between team members, it was decided that Greg would focus on realizing the vision of RChain. The RChain organizations (the Co-op and RChain Holdings company, which is now named Pithia) formed in December 2016 – January 2017. Reflective Ventures formed shortly after.
