## 1. Licensing Model

### 1.1. Core Principles

| Parameter | Value |
|-----------|-------|
| License type | Perpetual |
| Term | Unlimited |
| Updates | Free for 5 years for token holders |
| Revocation | License cannot be revoked by the company |

### 1.2. License and Tokens

Each DLE license is tied to a **governance token on the blockchain**. The token confirms the right to use the platform and grants a vote in product development.

| Parameter | 1 token | 10 tokens |
|-----------|---------|-----------|
| Number of licenses | 1 | 1 |
| Lines of business | 1 | 1 |
| Votes in voting | 1 | 10 |
| Service terms | Same | Same |

**Voting:** 1 token = 1 vote. Decisions are made by majority (51%+) via smart contract on the blockchain.

### 1.3. Line of Business

- One license — one line of business.
- Separate licenses required for multiple lines of business.

---

## 10. Governance Smart Contract

### 10.1. Architecture

DLE uses an on-chain smart contract for licenses and voting:

- **ERC20** — each license is represented by governance tokens (1 or 10)
- **ERC20Votes** — built-in voting
- **ERC20Permit** — signatures for gasless transfers
- **Multichain** — voting supported across multiple networks

### 10.2. Voting via Smart Contract

**Creating proposals:** token holders only. Voting duration: 1 hour to 30 days.

**Process:** proposal → voting (1 token = 1 vote) → quorum 51%+ → execution.

**Execution:** via direct call on the voting chain or via signatures on other chains.

### 10.3. Contract Security

- ReentrancyGuard
- Tokens transfer only through governance
- Vote snapshots vs flash-loans
- EIP-712 signatures for contract wallets
- All parameters validated before execution

### 10.4. License Transfer

License = tokens tied to wallet address. Transfer = moving tokens to a new address through governance. New owner automatically gets voting rights.
