The Block Pro, on X platform, stated that various attempts have been made to achieve Bitcoin scalability so far. The Lightning Network stands out as the most significant scalability solution for Bitcoin, with a Total Value Locked (TVL) reaching nearly $200 million in 2023, primarily driven by the increase in Bitcoin's price.
Other Bitcoin scalability solutions like DeFiChain, Rootstock, and Stacks have lower TVL compared to the Lightning Network, possibly due to security trade-offs as they inherit only partial security from Bitcoin.
Additionally, Bitcoin Ordinals allocate unique identifiers for satoshis, enabling them to function as NFTs. With the use of SegWit and Taproot upgrades, homogeneous BRC-20 tokens can be minted. These innovations resulting from the SegWit and Taproot upgrades demonstrate the potential of Bitcoin in areas like Layer 2 in the future.
