Play with DAO - Create a DAO in TVM Networks

The DaoRoot contract is a core component of a decentralized autonomous organization (DAO) system written in Ever-Solidity. It serves as the root contract managing proposals, configurations, staking accounts, and interactions with other modules within the DAO. Here's a structured explanation:

---

1. Imports and Dependencies

The contract imports libraries, interfaces, and utility components to provide essential functionality:

• Structures: PlatformTypes defines types used within the DAO system.
• Libraries: Includes utility libraries for gas management (Gas), error handling (DaoErrors), and message flag operations (MsgFlag).
• Interfaces: Interfaces like IDaoRoot, IStakingAccount, and IProposer define the interaction points for proposals, staking accounts, and upgradability.
• Utilities: Additional utilities (Delegate, DaoCellEncoder) support encoding, delegation, and managing data.

---

2. Contract Constants

These constants define the operational limits and parameters of the DAO:

• Proposal Limits: Maximum operations per proposal, description length, and thresholds for proposal quorum, voting period, delay, time lock, and grace period.
• Static Variables: _nonce is a unique identifier.

---

3. State Variables

Key state variables manage the configuration and current status of the DAO:

• Addresses: stakingRoot points to the staking system, admin and pendingAdmin manage DAO administration.
• Proposals: proposalCount, proposalConfiguration, and proposalCode handle the state of proposals.
• Deployment: deployEventValue manages the value required for Ethereum event deployments.

---

4. Modifiers

Modifiers enforce access control and validation:

• onlyAdmin: Restricts functions to the admin or delegated roles.
• onlyProposal: Ensures that only valid proposals can call certain functions.
• onlyStakingAccount: Restricts calls to authorized staking accounts.

---

5. Constructor

The constructor initializes the DAO:

• Parameters: Platform code, initial proposal configuration, and the admin address.
• Validation: Ensures the admin address and configuration are valid.

---

6. Getter Functions

Read-only functions provide public access to key data like admin, proposalCount, and expected addresses for proposals or staking accounts.

---

7. Proposal Functions

Core functionality for managing proposals:

• Propose: Accepts new proposals, validates actions, and interacts with the staking account for submission.
• DeployProposal: Deploys proposals with unique IDs and initializes platform state.
• Proposal Actions: onProposalSucceeded executes proposal actions (Ton and Ethereum-based) when approved.
• Helpers: Functions to calculate gas costs for actions (calcTvmActionsValue, calcBtcActionsValue).

---

8. Admin Functions

Administrative operations manage configurations and upgrades:

• Configuration Updates: Modify parameters like voting delay, quorum, thresholds, and event configurations.
• Admin Management: Transfer or accept admin rights.
• Code Upgrades: Allows upgrading the contract logic and proposals through the upgrade function.

---

9. Internal Utilities

Internal functions handle lower-level tasks:

• State Initialization: Functions like buildProposalStateInit prepare the state for proposals.
• Validation: Ensures that configurations (e.g., voting periods, thresholds) meet predefined limits.
• Delegation: Manage delegation for certain operations.

---

10. Event Emissions

The contract emits events for key actions, such as proposal creation, admin transfer, configuration updates, and upgrades, ensuring transparency.

---

11. Security and Gas Management

The contract uses tvm.rawReserve to optimize gas usage and prevent attacks by reserving the required balance for operations.

---

12. Upgradability

The upgrade function facilitates contract upgrades by accepting new code and reinitializing the contract state.

---

Key Features Summary:

1. Proposal Management: Create, deploy, and execute proposals with strict validation.
2. Configuration Flexibility: Update DAO parameters through admin functions.
3. Staking Integration: Tightly coupled with staking accounts for proposal submission.
4. Access Control: Multiple levels of restrictions ensure secure operations.
5. Upgradability: Future-proof design with support for logic upgrades.

This modular structure ensures scalability, security, and flexibility for a DAO system.
