The true ultimate vision of DeFi should be a global financial system centered around Bitcoin as the core asset. Bitlayer is driving this vision into reality. Through Rollup technology and the YBTC mechanism, BTC is no longer just a statically stored value but can participate in various financial activities such as lending, stablecoins, and derivatives. This not only enhances capital efficiency but also allows Bitcoin holders to truly integrate into the DeFi world and enjoy the opportunities brought by financial innovation.
