Odaily Planet Daily reports that, according to official sources, the BTTC 2.0 mainnet—built on a three-layer architecture and PoS consensus—has been fully launched today. The BTTC 2.0 mainnet establishes a secure and efficient cross-chain relay network, enabling seamless interoperability across multiple blockchain ecosystems and providing foundational infrastructure for DeFi, digital assets, and on-chain identity. Notably, the platform has introduced an innovative validator partner mechanism, which not only supports multi-address joint staking for node co-construction but also enables automatic proportional distribution of staking rewards via smart contracts. Currently, $BTT holders participating in network governance can enjoy an annualized yield of up to 6.7%.
