While Bitcoin (BTC) has cemented itself as the largest cryptocurrency by market capitalization, the underlying network has been distanced from the overwhelming growth of the broader blockchain ecosystem. Due to the absence of smart contract capabilities, the presence of decentralized finance (DeFi) products and services are minimal on the Bitcoin network. Solutions, including layer-2 projects and sidechains, are taking shape, each aimed at unlocking smart contract capabilities and adding more features to the Bitcoin network. BTC’s widespread recognition can play a key role in taking DeFi to a new plateau, and third-generation projects have started tapping into its yet unrealized potential.
