Overview

This PR implements a comprehensive Decentralized Autonomous Organization (DAO) smart contract for collective Bitcoin investment management on the Stacks blockchain. The implementation includes core DAO functionality such as membership management, proposal creation, voting mechanisms, and automated execution systems.

Changes

Data Structure Implementation

  • Added contract metadata and error constants
  • Implemented data variables for DAO governance parameters
  • Created data maps for:
    • Member management and staking records
    • Proposal tracking and status management
    • Vote recording and tabulation

Core Functionality

  • Membership System

    • Implemented token staking/unstaking mechanisms
    • Added member validation and voting power calculation
    • Created membership status tracking
  • Proposal Management

    • Added proposal creation with validation
    • Implemented proposal lifecycle management
    • Added quorum and duration controls
  • Voting System

    • Implemented weighted voting based on stake
    • Added vote validation and recording
    • Created vote power calculation system
  • Execution System

    • Added automated proposal execution
    • Implemented threshold validation
    • Created status update mechanisms

Read-Only Functions

  • Added comprehensive getter functions for:
    • Member information
    • Proposal details
    • Vote records
    • Overall DAO metrics

Testing

  • Contract functions tested in Clarinet console
  • Verified with test wallets and sample transactions
  • Validated error handling and edge cases

Security Considerations

  • Implemented authorization checks
  • Added input validation
  • Created balance verification
  • Added status checks for operations
  • Implemented proper principal validation

Documentation

  • Added comprehensive README
  • Included usage examples
  • Documented error codes
  • Added development guidelines

Future Improvements

  • Dynamic voting periods
  • Enhanced reward distribution
  • Proposal delegation system
  • Emergency pause mechanism

Checklist

  • Contract metadata and constants defined
  • Core data structures implemented
  • Member management system complete
  • Proposal system implemented
  • Voting mechanism tested
  • Execution system verified
  • Read-only functions added
  • Documentation updated
  • Security checks implemented
  • Error handling verified
  • Test cases completed

Deployment Notes

The contract should be deployed with initial parameters:

  • Minimum proposal amount: 1,000,000 uSTX
  • Proposal duration: 144 blocks
  • Quorum threshold: 50% (500 basis points)

Review Guidelines

Please review:

  1. Token staking mechanism security
  2. Proposal creation validation
  3. Vote calculation accuracy
  4. Execution conditions
  5. Error handling completeness

- Added metadata including title, summary, and description for the Bitcoin Investment DAO smart contract.
- Defined error constants for various contract operations such as authorization, invalid amounts, proposal status, and balance checks.
- Defined `dao-owner` to store the principal of the DAO owner.
- Added `total-staked` to track the total amount of tokens staked.
- Included `proposal-count` to keep a count of proposals.
- Set `quorum-threshold` to define the required quorum in basis points.
- Defined `proposal-duration` to specify the duration of proposals in blocks.
- Added `min-proposal-amount` to set the minimum amount required for a proposal in uSTX.
- Defined `members` map to store information about each member.
- Each member entry includes:
  - `staked-amount`: The amount of tokens staked by the member.
  - `last-reward-block`: The block number when the member last claimed rewards.
  - `rewards-claimed`: The total rewards claimed by the member.
- Defined `proposals` map to store information about each proposal.
- Each proposal entry includes:
  - `proposer`: The principal who created the proposal.
  - `title`: The title of the proposal.
  - `description`: A detailed description of the proposal.
  - `amount`: The amount of tokens involved in the proposal.
  - `recipient`: The principal who will receive the tokens if the proposal is approved.
  - `start-block`: The block number when the proposal starts.
  - `end-block`: The block number when the proposal ends.
  - `yes-votes`: The number of votes in favor of the proposal.
  - `no-votes`: The number of votes against the proposal.
  - `status`: The current status of the proposal.
  - `executed`: A boolean indicating whether the proposal has been executed.
- Defined `votes` map to store votes for each proposal.
- Each vote entry includes:
  - `proposal-id`: The ID of the proposal being voted on.
  - `voter`: The principal of the voter.
  - `vote`: A boolean indicating the vote (true for yes, false for no).
- Added `is-dao-owner` function to check if the transaction sender is the DAO owner.
- Added `is-member` function to check if a given address is a member with a staked amount greater than zero.
- Added `get-proposal-status` function to retrieve the status of a proposal by its ID.
- Returns the status if the proposal exists, otherwise returns "NOT_FOUND".
- Added `calculate-voting-power` function to determine the voting power of a given address.
- Returns the staked amount of the member if they exist, otherwise returns zero.
- Added `initialize` function to set a new DAO owner.
- Checks if the transaction sender is the current DAO owner.
- Sets the new owner if the check passes.
- Added `stake-tokens` function to allow members to stake tokens.
- Retrieves the current balance of the member or initializes it if not present.
- Asserts that the amount to stake is valid.
- Transfers the specified amount of tokens from the sender to the contract.
- Updates the member's staked amount, last reward block, and total staked tokens.
- Added `unstake-tokens` function to allow members to unstake tokens.
- Retrieves the current balance of the member or initializes it if not present.
- Asserts that the member has sufficient staked balance to unstake the specified amount.
- Transfers the specified amount of tokens from the contract to the sender.
- Updates the member's staked amount, last reward block, and total staked tokens.
- Added `create-proposal` function to allow members to create new proposals.
- Generates a new proposal ID and calculates the proposer's voting power.
- Asserts that the proposer has sufficient stake and the amount is valid.
- Sets the proposal details including title, description, amount, recipient, start and end blocks, votes, status, and execution status.
- Updates the proposal count and returns the new proposal ID.
- Added `vote` function to allow members to vote on proposals.
- Retrieves the proposal and calculates the voter's voting power.
- Asserts that the voter is a member, the proposal is active, the proposal has not expired, and the voter has not already voted.
- Records the vote and updates the proposal's yes or no votes based on the voter's choice.
- Added `execute-proposal` function to execute proposals after voting ends.
- Retrieves the proposal and checks if it exists.
- Asserts that the proposal has ended and has not been executed yet.
- Checks if the proposal meets the quorum threshold and has more yes votes than no votes.
- If approved, transfers the proposal amount to the recipient and updates the proposal status to "EXECUTED".
- If rejected, updates the proposal status to "REJECTED".
- Added `get-member-info` function to retrieve information about a member.
- Added `get-proposal-info` function to retrieve information about a proposal.
- Added `get-vote-info` function to retrieve information about a vote on a proposal.
- Added `get-dao-info` function to retrieve overall information about the DAO.
- Returns the total staked amount, proposal count, quorum threshold, and minimum proposal amount.
