The BTTC 2.0 mainnet, featuring a three-layer architecture and PoS consensus, has officially launched. This new mainnet enhances interoperability across multiple blockchain ecosystems through a secure cross-chain relay network, supporting DeFi, digital assets, and on-chain identities. A notable feature is the validator partner mechanism, which allows multi-address joint staking and node co-building, with staking income automatically distributed via smart contracts. $BTT holders can earn an annualized return of up to 6.7% by participating in network governance.
