What is Multisignature (Multisig) Technology?
Multisignature (Multisig) is a secure, reliable, and practical cryptographic technology that enhances asset custody safety and strengthens client trust. At its core, Mixin's blockchain natively supports ed25519-based multisignature transactions, allowing flexible "t/M" configurations where:
- t = threshold (minimum required signatures)
- M = members (total participants, up to 255)
For example, a 2/3 multisig means three parties co-manage assets, with any two signatures required to authorize transactions—a significant security upgrade over single-key custody.
Key Differences from Traditional Multisig
Unlike Bitcoin's 3-prefixed multisig addresses, Mixin implements UTXO-based multisig without fixed addresses. Transactions designate:
- A group of recipients
- A threshold value
- Shared ownership among participants

Practical Applications of Multisignature Technology
1. Asset Management Security
Multisig revolutionizes collective asset management by:
- Eliminating single points of failure
- Requiring consensus for fund movements
- Preventing unilateral access
Notable Implementations:
- Mixin Multisig Bot (7000102367): Open-source, frontend-only solution
- CoWallet (7000103970): Multi-currency wallet by Pando Team
2. E-Commerce Safeguards
The 2/3 model transforms online transactions:
Participants:
1. Buyer
2. Seller
3. Platform (arbiter)- Funds held in escrow until delivery confirmation
- Dispute resolution via platform arbitration
- Reduced fraud risk in marketplaces like ExinLocal (7000000015)

3. Government Workflow Automation
Multisig enables secure hierarchical approvals:
4/4 Financial Workflow Example:
1. Initiator (Marketing)
2. Department Head
3. Finance Officer
4. Treasurer- Chain-of-command transaction signing
- Automated payment releases
- Immutable blockchain records
4. Blockchain Consensus Mechanisms
Mixin pioneers multisig-based consensus for:
- Infinitely scalable sharding networks

Frequently Asked Questions
Q: How many participants can a Mixin multisig support?
A: Up to 255 members per multisig group.
Q: Can one user participate in multiple multisig groups?
A: Yes, users can simultaneously belong to different multisig configurations.
Q: What prevents multisig transaction tampering?
A: ed25519 cryptographic signatures ensure only valid participant approvals execute transactions.
Q: Is multisig slower than traditional transactions?
A: Slightly—the added security layer requires collecting signatures, but modern implementations minimize delay.
Q: How does multisig compare to smart contracts for escrow?
A: Multisig offers simpler, more auditable solutions for basic escrow needs without complex programming.
Q: Can multisig recover lost private keys?
A: No—lost keys still require threshold-1 other signatures. Always backup keys securely.
