SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Exfer enables secure, decentralized machine-to-machine payments by providing a permissionless PoW blockchain with finality, designed to empower autonomous agents to transfer value and enforce contracts without trusted intermediaries.

Core Features & Use Cases

  • Permissionless proof-of-work blockchain with finality for autonomous machine commerce.
  • Extended UTXO model and Exfer Script for deterministic, verifiable transaction conditions.
  • Covenants like HTLCs, multisig, vaults, escrow, and delegation enable complex module-based workflows such as cross-agent payments and automated agreements.

Quick Start

Initialize an Exfer node and start mining to participate in autonomous machine payments.

FAQPage Schema
How do I enable autonomous machine-to-machine payments on a decentralized network?

Autonomous machine-to-machine payments are enabled via a permissionless proof-of-work blockchain with finality, allowing agents to transfer value and enforce contracts without trusted intermediaries. You can initialize a node and start mining to participate.

What is an extended UTXO model and how does it support autonomous agent contracts?

An extended UTXO model combined with Exfer Script provides deterministic, verifiable transaction conditions for autonomous agents. It supports covenants like HTLCs, multisig, vaults, escrow, and delegation to enable complex automated workflows.

Can I use HTLCs and escrow for cross-agent payments without intermediaries?

Yes, HTLCs and escrow can be implemented for cross-agent payments without intermediaries using covenant templates. These templates operate within the extended UTXO model to enforce contract conditions deterministically.

Does the network require specific mining algorithms for autonomous machine commerce?

The network requires Argon2id proof-of-work mining to achieve finality and secure autonomous machine commerce. This consensus mechanism ensures permissionless participation and decentralized value transfers.

What are the limitations of using a PoW blockchain for automated machine payments?

Using a PoW blockchain for automated machine payments requires mining to achieve block finality, meaning transaction throughput and confirmation times are bounded by the deterministic costs of the network's script execution and consensus.

How do I initialize a node for autonomous machine payments?

To initialize a node for autonomous machine payments, you join the permissionless proof-of-work network and start mining. This allows your autonomous agents to check balances, transfer value, and enforce contract conditions.
