C3IP3 - Revise the C3 token emission

Summary: Revise the C3 token emission schedule to extend the protocol’s adoption timeline.

Motivation: Shortly after the launch of C3 in March 2022, all major carbon credit registries established moratoria on one-way bridging, rendering C3’s initial one-way bridge product inoperable and dramatically slowing adoption of digital carbon. The original token emission schedule had C3 reaching max supply in four years. However, given that it has now been almost a year since tokenization was halted and there is still no indication of major registries supporting any form of tokenization in the immediate future, the C3 community should consider adjusting the emissions schedule of C3.

Proposal: Until tokenization is supported by mainstream registries, this proposal will substantially reduce the issuance of rewards.by extending the C3 emission schedule till 2030.
