Bitcoin Investment DAO

A decentralized autonomous organization (DAO) smart contract built on Stacks blockchain for collectively managing Bitcoin investments. This DAO enables members to pool resources, create proposals, vote on investment decisions, and execute approved transactions.

Features

• Membership Management: Join the DAO by paying a membership fee in STX
• Proposal System: Create and vote on investment proposals
• Democratic Governance: Weighted voting based on member stakes
• Treasury Management: Secure handling of pooled funds
• Automated Execution: Automatic execution of approved proposals

Technical Overview

Core Components

1. Membership System

   • Minimum membership fee: 1 STX (1,000,000 microSTX)
   • Each member's voting power is proportional to their STX contribution
   • Member data tracking includes:
     • Join date
     • STX balance
     • Voting power
     • Proposals created
     • Last vote timestamp

2. Proposal System

   • Proposal duration: ~1 day (144 blocks)
   • Quorum threshold: 51%
   • Proposal data includes:
     • Title (max 50 characters)
     • Description (max 500 characters)
     • Requested amount
     • Recipient address
     • Voting statistics
     • Execution status

3. Voting Mechanism

   • One voting power per STX contributed
   • Members can only vote once per proposal
   • Votes are immutable once cast
   • Vote tracking includes both the decision and voting power used

Usage Guide

Joining the DAO

(contract-call? .bitcoin-investment-dao join-dao)

Requires sending the minimum membership fee (1 STX). Upon successful joining, member data is initialized and the treasury balance is updated.

Creating a Proposal

(contract-call? .bitcoin-investment-dao create-proposal
    "Investment in BTC Mining"
    "Proposal to invest in mining equipment"
    u5000000000
    'SP2J6ZY48GV1EZ5V2V5RB9MP66SW86PYKKNRV9EJ7)

Creates a new investment proposal. Requirements:

• Must be a DAO member
• Requested amount must be within treasury balance
• Title and description must not be empty
• Valid recipient address

Voting on Proposals

(contract-call? .bitcoin-investment-dao vote-on-proposal u1 true)

Cast a vote on a proposal. Requirements:

• Must be a DAO member
• Proposal must be active
• Haven't voted on this proposal before

Executing Proposals

(contract-call? .bitcoin-investment-dao execute-proposal u1)

Execute a successful proposal. Requirements:

• Proposal must have ended
• Must meet quorum threshold
• Must not be already executed

Security Considerations

1. Funds Safety

   • All treasury operations are controlled by the contract
   • Proposals require majority approval and quorum
   • Member balances are tracked separately from voting power

2. Vote Integrity

   • Single vote per member per proposal
   • Votes cannot be changed once cast
   • Voting power is proportional to stake

3. Proposal Lifecycle

   • Clear timeframes for voting
   • Automated execution checks
   • Prevention of double execution
