Nexus Market

2-of-3 Multisig Escrow

What is Multisig?

Multisig (multi-signature) is a security feature that requires multiple signatures to authorize a transaction. In the context of Nexus Market, 2-of-3 multisig means that three keys exist for each escrow, but only two are required to release funds.

This system provides enhanced security by distributing trust among multiple parties and preventing any single entity from unilaterally controlling funds.

How 2-of-3 Multisig Works

In Nexus Market's implementation:

  • Key 1: Controlled by the buyer
  • Key 2: Controlled by the vendor
  • Key 3: Controlled by Nexus Market (trusted third party)

Any two of these three keys can authorize a transaction, but no single party has complete control.

Transaction Flow

A typical transaction using 2-of-3 multisig follows this process:

[1] Buyer sends funds to multisig address

↓

[2] Vendor receives order notification

↓

[3] Vendor ships product/delivers service

↓

[4] Buyer confirms receipt and signs

↓

[5] Vendor signs to release funds

↓

[6] Transaction completes

If there's a dispute, Nexus Market can act as the third party to resolve it:

Dispute Resolution:

Buyer signs + Nexus Market signs = Funds released to vendor

Vendor signs + Nexus Market signs = Funds returned to buyer

Benefits of 2-of-3 Multisig

  • Enhanced Security - No single point of failure or control
  • Fraud Protection - Both parties must agree to complete transactions
  • Dispute Resolution - Trusted third party can mediate conflicts
  • Reduced Risk - Neither buyers nor vendors can unilaterally steal funds
  • Transparency - All parties can verify transaction status

Key Management

Proper key management is essential for multisig security:

  • Store your private keys securely using hardware wallets or encrypted storage
  • Never share your private keys with anyone
  • Backup your keys in multiple secure locations
  • Use strong, unique passwords for key storage
  • Regularly verify you can access your keys

Important Security Considerations

While multisig provides enhanced security, it's not foolproof:

  • If you lose access to your key, you cannot complete transactions
  • Nexus Market retains the ability to influence outcomes through their key
  • Complexity can lead to user errors
  • Recovery options may be limited if keys are lost

Always follow best practices for key security and understand the process before engaging in transactions.

Dispute Resolution Process

When disputes arise, Nexus Market follows this process:

  1. Both parties submit evidence through the dispute system
  2. Nexus Market reviews the evidence impartially
  3. A decision is made based on marketplace rules and evidence
  4. The third key is used to execute the resolution
  5. Both parties are notified of the outcome

This process ensures fair treatment while maintaining the security benefits of multisig.
