We're excited to announce O＝C＝O, a decentralized, equitable cap-and-trade system built to advance climate accountability and ensure fair, transparent management of carbon emissions.

O＝C＝O enforces a global emissions cap by allocating an equal carbon allowance to every verified individual. Each allowance is represented by the OCO ERC20 token. Once verified through proof-of-personhood, users can claim their personal carbon allowance, use it directly to offset their own emissions, or trade it freely on open markets. Importantly, the system encourages users to burn OCO tokens equivalent to the amount of CO₂ they emit, fostering personal responsibility and active participation in global carbon reduction efforts.

PileumConnect is a public OpenID Connect Provider designed for proof of personhood and privacy.

Users must own a french electronic national identity card to register an account and prove their identity. The user's identity is processed directly in the browser, ensuring it is never transmitted over the internet.

Any OpenID Connect Relying Party can use the service to authenticate its users : the only user information provided is a Pairwise Pseudonymous Identifier (PPID). PPID is the identifier of a User to a Relying Party and cannot be correlated with the User's PPID at another Relying Party.

PileumConnect also extends the official OpenID Connect specifications with EIP-712 signatures to make authentication responses compatible with Ethereum smart contracts.
