The self-evolution of Bitcoin: L2 is a misguided path, native upgrades are the correct answer.
Bitcoin refuses to become a 'programmable financial platform', but can iterate through native technology to balance functionality and security:
Lightning Network: has supported instant micropayments (channel capacity exceeds $200 million), without the need for complex L2;
OP_CAT upgrade: after activation in 2025, will support simple contracts, enabling asset custody directly on the mainnet;
Sidechain Autonomy: such as Liquid Network, which bears its own risks by exchanges, not polluting the mainnet's value storage attributes.
Satirical Comparison:
Bitlayer raises $25 million to build 'Bitcoin DeFi';
Bitcoin developer Jameson Lopp completed the Schnorr signature upgrade with a budget of $50,000, improving efficiency by 30%.
