Bitcoin is increasingly integrating into the decentralized finance (DeFi) space, moving beyond its traditional role as a peer-to-peer currency. The total value locked in Bitcoin-related DeFi platforms has surged to $1.31 billion, with significant contributions from platforms like Core, Rootstock, and Merlin Chain. Bitcoin's DeFi involvement initially saw $1.07 billion in total value locked. Additionally, Bitcoin Layer 2 and sidechain networks have seen substantial growth, with notable activity on the BOB dashboard since its launch in late April and spikes in May and July. The supply of tBTC on the BOB platform is also showing strong metrics, indicating a robust ecosystem. This expansion signifies Bitcoin's growing acceptance and potential to bring millions of new liquidity into the DeFi sector.
