Unveiling Sui High-Performance Technology and Contract Security

探索 Sui：高性能背后的技术与合约安全 – 信息提取

This articleprovides a detailed analysis of Sui, a new high-performance blockchain platform, focusing on its technicalfeatures and contract security. Here’s a breakdown of the key information:

Sui’s Technical Features:

Account Model: Sui follows BIP-32, BIP-44, and BIP-39 standards for key management, supporting Ed25519, Secp256k1,Secp256r1, and MultiSig. Sui addresses are derived using BLAKE2b hash function.
Balance Management: Balances are represented as objects in Sui. Transactions involve splitting or merging objects to match thedesired amount.
Token Management: Sui utilizes the Coin standard code for token issuance. Developers can use the sui::coin library for functionalities like create_regulated_currency, mint, and transfer.
Transaction Mechanism: Sui transactions are built using the Move programming language. Each transaction explicitly specifies the objects it operates on. Transactions include sender, instruction list, input parameters, and gas object.

Sui’s Contract Security:

Move Language: Move is designed to address vulnerabilities common in Solidity, such as reentrancy attacks, integer overflows, double-spending, DoS attacks, and compiler issues.
Security Audit: Despite Move’s advantages, security audits remain crucial to identify developer-introduced errors.
Developer Considerations:
- Permission Checks: Analyze object types and ensure sensitive operations are performedonly by authorized users.
- External Function Checks: Identify functions that should not be publicly accessible and restrict their exposure.
- Object Analysis: Classify objects as static or public and ensure proper usage.
- Coin Consumption Checks: Verify correct amount consumption, object transfer, and split amounts.
Oracle Price Manipulation Attacks: Implement multiple data sources and consensus mechanisms to prevent manipulation.
- Governance Attacks: Design a robust governance system to prevent malicious attacks.
- Arbitrage Attacks: Carefully review DeFi contract logic to prevent exploitation.
- Fake Deposit Attacks: Verify transaction status and packageID to prevent fake deposits.

Conclusion:

Sui’s innovative design, utilizing Move language and object storage, offers high performance, low latency, and enhanced security. While Move mitigates common vulnerabilities, developers need to focus on business logic security, particularly in permission management, object types, and coin consumption.
