To encourage developer participation, Sirius is distributed for free among developers and blockchain enthusiasts. Sirius features an initial supply of 100 million SIRX, with approximately 1% inflation per year. The Sirius protocol implements the Reputation-Weighted Proof-of-Stake (RWPoS) algorithm, which will boost transaction speed to 4300 TPS and beyond with a minimized degradation of decentralization and make 51% attacks infeasible.
