Smart Contract Security Best Practices
블록체인 기반 스마트 계약의 안전한 코딩, 테스트 및 배포에 대한 가이드라인으로, 취약점을 방지하고 사용자를 보호합니다.
Smart contract security best practices는 안전한 코딩, 엄격한 검토, 포괄적인 테스트(unit, integration, penetration), 위협 모델링, 가능한 경우 formal verification, 그리고 견고한 배포 및 운영 제어를 포함합니다. 주요 영역에는 일반적인 exploit vector(reentrancy, access control weaknesses, arithmetic errors, timestamp/block-related dependencies 등)를 방지하기 위한 안전한 코딩; 철저한 코드 검토 및 문서화; unit, integration, 시뮬레이션된 프로덕션 환경 전반에 걸친 계층적 테스트; 위협 모델링 및 안전한 upgrade 패턴; dependency management 및 supply chain security; 독립적인 보안 회사의 감사; 그리고 배포 후 모니터링 및 incident response가 포함됩니다.

❓ 자주 묻는 질문
What is a smart contract?
A self-executing agreement encoded on a blockchain that enforces terms automatically when predefined conditions are met.
Why are security practices important?
Smart contracts are often immutable or hard to change; vulnerabilities can lead to loss of funds and trust.
What is reentrancy?
A vulnerability where a contract calls an external contract which then calls back into the original contract before state updates, enabling exploits.
What is formal verification?
A mathematical proof that a contract's behavior adheres to a specification, increasing assurance.
