The secp256k1 implementation of Solana has drawn community attention. It is reported that the development team referred to Ethereum's modexp scheme when building this encryption algorithm, and the performance is indeed impressive. However, the problem lies in the fact that only after deploying to the Mainnet was it discovered that this implementation has a significant denial-of-service (DoS) attack vector. Ironically, the developers apparently did not conduct an accurate cost assessment of this security risk and simply disabled the feature. This "enter a position and then pay" approach has sparked considerable discussion within the ecosystem and serves as a reminder for developers to maintain a more cautious balance between performance optimization and security protection.
