Understanding Multi-Signature Wallets in Blockchain
The blockchain era has made digital currencies increasingly mainstream, elevating the importance of secure wallet management. Among various wallet features, multi-signature functionality stands out for its enhanced security and collaborative capabilities. This guide explains how multiple users can collectively manage a single wallet using TronLink's multi-signature system.
Single-Signature vs. Multi-Signature: Key Differences
- Single-Signature: Standard transactions (transfers, approvals, trades) require only one user's authorization.
Multi-Signature: Transactions demand multiple approvals before execution. For example:
- If User A initiates a 1000 TRX transfer from Wallet X, Users B and C must approve it.
- Failure to secure all required signatures cancels the transaction.
Three Permission Levels in Multi-Signature Wallets
| Permission | Capabilities | Notes |
|---|---|---|
| Owner | Full control over all operations | Each address has one Owner group |
| Witness | Block production (for super representatives) | Irrelevant for standard users |
| Active | Customizable permissions (combine multiple rights) | Max 8 groups per address |

3. Execute a Multi-Signature Transaction
- Initiate transfer → Enable "Multi-Signature Transfer".
- Enter controlling account address (e.g., Wallet A).
- Specify recipient and amount.
- First Approver: Confirm transaction with their password.
Second Approver:

Handling Signature Requests

Cost Considerations
- Setup Fee: ~100 TRX + 500 bandwidth units.
