After reading this chart of the Bitcoin project's Trilemma, I have a deep impression. Finding a balance between the three dimensions of native, speed, and programmability is particularly challenging. Nature has also given birth to various solutions with different choices and emphasis on routes: 1) Exploration of Native and Cross Chain Security: The Bitcoin mainnet is limited by the UTXO script space and verification logic, making it difficult to natively support complex smart contract functions. Therefore, there are many technical paths to explore native cross chain solutions, but they are all supported by technical complexity, such as the method based on cryptographic algorithm security reinforcement and Cosmos SDK chain linkage represented by @ babylonlabs_io; For example@ GOATRollup, BitcoinOS and other universal native verification solutions based on ZK technology@ Nubit_org uploads the data proof to the Bitcoin mainnet, fully utilizing Bitcoin's security model. 2) The trade-off between speed and programmability: In terms of programmability, the BTC layer2 market is undergoing a transitional phase from wild growth to standard narrowing. In the early stage, various solutions such as EVM Compatible, UTXO Stack isomorphic binding, UTXO parallel stacking, BitVM off chain Turing completeness, RGB native, AVM virtual machine, etc. coexisted, but with market screening, the technical route is gradually converging. It seems that the convergence of the technological route is actually due to the market choosing some specific trade-off strategies, paying more attention to the comprehensive capabilities of the chain, such as avoiding extreme routes, such as EVM Compatible, which sacrifices the original for programmable speed. In short, the future of the Bitcoin ecosystem may not lie in the victory of a single technological path, but in the coexistence and integration of multiple technological paths.
