CommonGround System Architecture

Overview

CommonGround is a local-first, federated governance system composed of modular services.

Core Services

Identity Service

• Decentralized identity (DIDs)
• Membership tracking
• Permissions

Governance Engine

• Proposal lifecycle
• Voting logic
• Quorum + thresholds
• Execution

Deliberation Service

• Structured arguments
• Perspective mapping
• Synthesis

Federation Layer

• Node-to-node sync
• Shared protocol
• Conflict resolution

Data Model

• Event-driven architecture
• Append-only logs
• CRDT or event sync

Smart Contract (Example)

contract Governance {

    struct Proposal {
        address proposer;
        uint256 support;
        uint256 createdAt;
        bool executed;
    }

    mapping(uint256 => Proposal) public proposals;

    function createProposal() public {
        require(rateLimit(msg.sender));
        proposals[id] = Proposal(msg.sender, 0, block.timestamp, false);
    }

    function supportProposal(uint256 id) public {
        proposals[id].support += 1;
    }

    function executeProposal(uint256 id) public {
        require(proposals[id].support >= threshold);
        require(quorumReached(id));
        proposals[id].executed = true;
    }
}

Design Principles

• Local-first
• Federated
• Interoperable
• Portable
• Privacy-first
• Forkable
