The Project PAI whitepaper outlines the importance of data storage, as it relates to Project PAI blockchain implementations.
This idea was formulated into a data storage and sharing protocol, PDP2.
It has most recently been further articulated with illustrations of data flows in the PAI data paper.
The current goal for this section of the website is to provide a hosted interface; where people can submit data to a testnet client and see the results in a testnet block explorer. This initiative is awaiting the completion of the testnet faucet and the testnet block explorer.
