PANews reported on November 22 that according to Galaxy Research data, Bitcoin Layer 2 (L2) projects have received a total of US$447 million in financing since 2018, accounting for more than 36% in 2024 alone. The report pointed out that currently about 0.8% of BTC circulation is locked in L2, wrapped assets and pledge agreements, and it is expected that this proportion will increase to 2.3% by 2030, corresponding to about US$47 billion in BTC liquidity.

The number of Bitcoin L2 projects has increased from 10 to 75 since 2021. Existing L2 solutions mainly include sidechains and Rollups technology, among which Rollups significantly improve transaction speed and reduce costs through data compression and batch processing. The report emphasizes that Bitcoin L2 provides BTC with more efficient transactions and revenue applications, but the current bridge mechanism and trust issues in asset withdrawal still need to be optimized.
