List of new and old projects in the Bitcoin Layer2 track

1. Bitcoin Layer 2 technology aims to improve Bitcoin's scalability, enabling it to handle a large number of transactions without slowing down transactions or increasing transaction prices.
2. Currently, the total locked value (TVL) of Bitcoin's Layer 2 projects is only a small fraction of Bitcoin's market value, but the situation is changing, and projects such as Lightning Network, Stacks, and Rootstock are growing and developing steadily.
3. New Bitcoin Layer 2 projects such as BEVM, B²Network, Dovi, MapProtocol, and MerlinChain are emerging, which use new technologies such as Schnorr signature algorithm, ZK-Rollup, and EVM compatibility to increase transaction speed and enhance privacy.
4. The development of Bitcoin Layer 2 is crucial to the promotion of the smart contract market. New projects such as BitVM and RGB are bringing innovative virtual machines and smart contract solutions to the Bitcoin network.
