Odaily Planet Daily News: According to official news, the BTTC 2.0 mainnet based on a three-layer architecture and PoS consensus has been fully launched today. The BTTC 2.0 mainnet achieves seamless interoperability across multiple blockchain ecosystems by constructing a secure and efficient cross-chain relay network, providing infrastructure support for DeFi, digital assets, and on-chain identities. Notably, the platform has innovatively introduced a validator partner mechanism, which not only supports multi-address joint staking to build nodes but also automatically allocates staking rewards proportionally through smart contracts. Currently, $BTT holders participating in network governance can enjoy an annualized return rate of up to 6.7%.
