Sirius is a planned Global Web3 Contribution Network that links identity, contribution, and reputation, under the idea of “Contribute First. Build Together.” Users get a Sirius ID and Passport that track participation from basic identity to builder status, while SST is only a contribution record, not a tradable token and with no promised financial return. The actual ecosystem token, SRT, is planned as a BEP-20 on BNB Smart Chain with a 5 billion max supply for missions, vesting, staking, and governance, but it is not live yet. The roadmap targets Genesis in Q4 2026, on-chain foundations in 2027, SRT allocation and a contribution marketplace in 2028, and an open ecosystem in 2029, so right now it is closer to a community and mission network than a launched token project.
