STARS is a public chain based on the BPOS consensus mechanism. In the future, it will create a blockchain ecosystem covering "public chain wallet + DeFi products + blockchain cross-border payment platform + diversified DAPP applications". STARS adopts the "dual pass dual economic model" and the "dual currency dual track" internal and external cycle operation mechanism. Its sub-token STC is a currency token with asset attributes, which can be used as a trading medium, storage value, deferred payment standard and record account unit. Combined with a unique incentive system, customizable smart contracts and a decentralized distributed service architecture, a distributed intelligent financial ecosystem with deep scalability and sustainable development will eventually be created.
