Odaily News The Block Pro posted on the X platform that so far, there have been various attempts to achieve Bitcoin expansion. The Lightning Network is Bitcoin’s largest scaling solution, with its TVL reaching nearly $200 million in 2023, primarily due to Bitcoin’s rising price. Other Bitcoin scaling solutions such as DeFiChain, Rootstock, and Stacks have lower TVL than Lightning Network, possibly due to security trade-offs as they only inherit part of Bitcoin’s security. Additionally, Bitcoin Ordinals assigns satoshi a unique identifier, enabling it to become an NFT, and uses SegWit and Taproot upgrades to mint fungible BRC-20 tokens. These innovations from SegWit and Taproot upgrades show Bitcoin’s future potential in areas such as Layer 2.
