链上钱包签名：数字资产交易的安全认证核心

Core Insights - On-chain wallet signatures are essential for ensuring the secure transfer of digital assets in a decentralized blockchain environment, functioning as an "electronic signature" that provides identity authentication for each transaction [1][3] - The technology is based on asymmetric encryption algorithms, where each blockchain wallet generates a pair of keys: a public key for sharing and a private key for secure signing [1][3] - The application of on-chain wallet signatures spans various core areas of the blockchain ecosystem, including cryptocurrency transfers, DeFi activities, NFT transactions, and Web3 applications [3][4] Security Advantages and Risks - The primary advantage of on-chain wallet signatures is their security, which relies entirely on the safeguarding of the private key; if compromised, it can lead to unauthorized transactions [4] - Users face risks from phishing websites that may trick them into authorizing signatures on fake pages, as well as potential vulnerabilities in signature algorithms or wallet applications [4] - To enhance signature security, the industry is continuously optimizing technical solutions, including the adoption of various signature algorithms and hardware wallets that keep private keys offline [4] Future Innovations - The ongoing innovation in on-chain wallet signatures includes the integration of privacy computing technologies to balance signature verification with privacy protection [5] - Cross-chain signature technology is expected to mature, allowing users to utilize the same signature system across different blockchain networks, thereby improving cross-chain transaction convenience [5] - User-friendly signature interaction designs are being developed to lower the usage barrier for ordinary users, achieving a better balance between security and ease of operation [5]
