Foundation Smart Contract

Overview:

The Foundation Smart Contract is a Solidity-based contract that facilitates the management of a committee with various roles (Research, Technical, FoundationMember) and the rotation of those roles using session keys. It provides a structured way to handle changes in committee member roles and enables role rotation based on specific criteria.

Features:

• Committee management with distinct roles.
• Role rotation mechanism using session keys.
• Role-based governance within the contract.
• Simulated role assignment based on session key data.

Getting Started:

Prerequisites:

To interact with the Foundation Smart Contract, you'll need:

• An Ethereum wallet with Ether for transaction fees.
• A Solidity development environment like Remix or Truffle.
• Basic knowledge of Ethereum and Solidity.

Usage:

Contract Initialization:

The contract should be deployed with the following parameters:

• researchMembers: An array of addresses representing Research committee members.
• technicalMembers: An array of addresses representing Technical committee members.
• foundationMembers: An array of addresses representing Foundation Member committee members.

Transferring Roles:

• The contract owner can initiate a new chain and rotate council members' roles using the initiateNewChain function.
• Committee members can trigger a role change using the changeMembersUsingSessionKeys function, which checks whether a rotation is due based on the rotationThreshold.

Advanced Features:

• The contract uses ECDSA cryptography for generating session key shares.
• It computes new roles for committee members based on session key data and a simulated role computation algorithm.
