STARS is a public blockchain based on the BPOS consensus mechanism, which in the future will establish an all-encompassing ecosystem covering "public chain wallet + DeFi products + blockchain cross-border payment platform + diversified DAPP applications." STARS adopts a "dual-token dual-economic model" and a "dual-currency dual-track" internal and external circulation mechanism. Its subsidiary token, STC, is a currency-type token with asset attributes that can be used as a medium of exchange, a store of value, a standard for deferred payments, and a unit of account. Combined with a unique incentive system, customizable smart contracts, and a decentralized distributed service architecture, it ultimately creates a deeply extensible and sustainably developing distributed smart financial ecosystem.
