Blockchain network Elastos is launching BeL2, a Bitcoin layer-2 network that could attract billions of dollars in BTC volumes from staking tools. BeL2 will enable more advanced bitcoin transactions, such as smart contracts and irreversible digital agreements, without the need for an intermediary. Users can also stake their bitcoin holdings directly on the platform, earning yields while interacting with BeL2-built applications. The introduction of BeL2 highlights the potential for Bitcoin holders to earn interest on their assets and join the growing trend of Bitcoin layer-2 projects.
