The original mining mechanism remained effective through the Beta and Testnet phases and in the early months of the Enclosed Mainnet period (until March 14, 2022) to support the network’s growth, distribution and security.

The design of the token supply model and the new mining mechanism based on a dynamic base mining rate for rewards issuance was released in the December 2021 Whitepaper in order to balance the need for network growth and token distribution with the need for predictability in planning, right-sizing rewards for different types of necessary contributions and maintaining long-term network incentives.

A specific rewards issuance formula was released on March 1, 2022, which adjusts the systemwide base mining rate monthly based on the supply limit.

The new mining mechanism with boosts for more diverse types of contributions, namely, Pi lockups, app usage and Node operations, went into effect on March 14, 2022. The changes support the long-term engagement with the network, engagement with the Pi app ecosystem as a whole and decentralization, security and longevity of the Pi blockchain.

Reevaluation of the rewards issuance formula, and the mining mechanism given the past data, to see if the data conforms to or deviates from the assumptions in the token model, and determine if there needs any adjustments or changes on either the formula and the mining mechanism to ensure the token model achieves its goals laid out in the 2021 December Whitepaper.

Possible newer mining bonuses (accounted for in the original mining mechanism in the variable X) to encourage newer forms of contributions based on evolving network needs.

These included: recommended ideas, feature requests, challenges, and previous experiences using Pi in local communities. Within 24 hours of posting this survey on the home screen of the Pi Mining app, the survey received responses from over 80,000 Pioneers eager to help in the development of the program.
