Difficulty in maintaining and updating contract terms; 2. Vulnerable to tampering and lack of security; 3. Reliant on third-party authoritative institutions for supervision, high cost of trust; 4. Opaque execution process, difficult to trace. Through smart contracts, blockchain technology achieves decentralization, trustlessness, autonomy, and tamper-proof characteristics, making the transaction process more secure,  efficient, and transparent. Smart contracts can be applied to various fields such as finance, management, healthcare, and IoT, reducing transaction costs and improving trust."}]}],"pr":"20c1dda4aa87e59ee9235b5b3ca18e37e4dd9937daa43e7be7658ee64c653e01"}
