Ownership Management Standard

CIP-102Category: CBCTag: DRAFT約2分

Standardized Ownership Management for Smart Contracts

Abstract

This CIP proposes a standardized way to handle ownership of smart contracts. The proposed standard abstracts ownership management, providing functions to transfer and renounce ownership securely.

Motivation

Ownership management is critical to smart contract security and governance. The proposed standard aims to provide a common, reusable, and secure pattern for managing ownership in smart contracts.

Specification

The CIP-102 Standard

State Variable:

  • _owner: Holds the address of the owner.

Events:

  • OwnershipTransferred: Emitted when ownership is transferred.

Constructor: Sets the contract deployer as the initial owner.

Functions:

  • owner: Returns the current owner's address.
  • renounceOwnership: Allows the current owner to relinquish ownership.
  • transferOwnership(address newOwner): Enables transferring ownership to a new address.

Modifiers:

  • onlyOwner: Restricts function access to the current owner.

Technical Details

  • Blockchain Compatibility: Core Blockchain (Ylem Version >0.8.0)
  • Contract Functions:
    • owner(): Returns the current owner's address.
    • renounceOwnership(): Allows the current owner to renounce their ownership.
    • transferOwnership(address newOwner): Transfers ownership to a new address.
    • onlyOwner: A modifier restricting function access to the contract's owner.
  • Event: OwnershipTransferred(address indexed previousOwner, address indexed newOwner): Emitted when ownership is transferred.

Rationale

The proposed standard simplifies ownership management in smart contracts, reducing the risk of unauthorized access and enabling clear governance structures. Its simplicity and clarity make it a suitable standard for various applications on Core Blockchain.

Backward Compatibility

The CIP-102 standard is compatible with all existing Core Improvement Proposals (CIPs) and does not interfere with existing blockchain architectures on Core Blockchain.

Security Considerations

Security is a primary concern in the design of the proposed standard. It includes checks to prevent unauthorized access and changes to contract ownership. Further security audits and reviews are recommended.

Conclusion

The CIP-102 Standard provides a simple and effective solution for managing ownership in smart contracts on Core Blockchain. It offers a clear and reusable pattern for implementing ownership-related functionalities essential for contract governance and security. By standardizing the approach to ownership management, the CIP-102 standard aims to reduce the risk of errors and vulnerabilities associated with ad-hoc implementations. This standard benefits contracts requiring a single owner or administrator, ensuring that critical functions are protected and governance is transparent.
