Foundation Committee v1 Smart Contract

This document provides an explanation of the "Foundation Committee v1" smart contract, which is designed to manage committee rotations and governance-related activities within a decentralized organization. The contract is written in Solidity and follows the ERC-20 standard.

Overview

The "Foundation Committee v1" contract is intended to facilitate the governance and decision-making processes of a decentralized organization. It allows the establishment of two types of committees: Technical and Research. Committee members are rotated based on session durations, and session keys are granted to authorized users who have the privilege to propose changes, rotate committee members, and approve multi-signature transactions.

Key Components

1. CommitteeType: An enumeration representing the types of committees, which include "Technical" and "Research."

2. CommitteeMember: A struct containing the rotation end timestamp for committee members.

3. sessionDuration: The duration of a committee session in seconds.

4. sessionCount: The number of sessions within a rotation period.

5. committees: A mapping that associates committee types with committee members and their rotation end timestamps.

6. sessionKeys: A mapping indicating addresses that are granted session keys for committee-related activities.

7. sessionExpiry: A mapping to track the expiration timestamps of session keys.

8. multiSignAggreApprovals: A mapping to track multi-signature approvals by session key holders.

Modifiers

• onlySessionKey(): A modifier that restricts functions to only be callable by addresses with valid session keys.

• onlyOwnerOrAdmin(): A modifier that allows only the contract owner or authorized session key holders to execute specific functions.

Functions

• addSessionKey(address _sessionKey): Adds a session key for a specified address, extending its session expiry time.

• rotateCommittee(CommitteeType _committeeType, address _newMember): Rotates committee members within a specified committee type.

• addTechnicalCommitteeMember(address _memberAddress): Adds a new member to the Technical committee.

• addResearchCommitteeMember(address _memberAddress): Adds a new member to the Research committee.

• proposeChange(string memory _proposalDetails): Allows a session key holder to propose changes.

• setDuration(uint256 _duration): Sets the duration of a committee session.

• setCount(uint256 _count): Sets the number of sessions within a rotation period.

• approveMultiSignAggre(uint256 _approvalIndex): Allows session key holders to approve multi-signature transactions.

• endSession(address _sessionKey): Ends a session for a specific session key.

Events

• SessionKeyAdded(address indexed sessionKey): Emitted when a new session key is added.

• CommitteeMemberRotated(CommitteeType committeeType, address indexed oldMember, address indexed newMember): Emitted when a committee member is rotated.

• ChangeProposed(address indexed proposer, string proposalDetails): Emitted when a change is proposed.

• SessionEnded(address indexed sessionKey): Emitted when a session ends for a session key.

Usage

The "Foundation Committee v1" smart contract allows authorized session key holders to manage committee rotations, propose changes, and approve multi-signature transactions. The contract can be deployed on a blockchain network, and session keys can be granted to users who need to participate in governance activities.

Please note that this is a high-level overview of the contract. In practice, additional considerations such as security audits, testing, and integration with other governance mechanisms may be necessary.
