# Contractless

Contractless is a new peer-to-peer blockchain built from the ground up around spendable digital money, native transaction types, and a consensus model called Fair Proof of Work.

Instead of rewarding specialized mining hardware with overwhelming advantage, Contractless limits mining attempts so ordinary hardware can participate on more equal footing. The chain includes native support for base-currency transfers, tokens, NFTs, swaps, loans, marketing records, and app-style data storage without requiring a smart-contract VM.

Contractless is currently in testnet. Node operators, developers, wallet testers, and application builders are encouraged to review the documentation, run testnet nodes, and help test the network.

For protocol design, mining rules, balance handling, orphan correction, and Fair Proof of Work details, read the [Contractless whitepaper](https://contractless.community/contractless_whitepaper.pdf).

## Development With Codex

Contractless is designed and developed by Bruce Bates. OpenAI Codex, including the GPT-5.6 SOL model, has been used as an AI-assisted development tool.

GPT-5.6 SOL assisted with:

- Reviewing and debugging peer connection, bootstrap, handshake, and automatic reconnection behavior.
- Tracing multi-node synchronization and orphan-correction failures across source code and node logs.
- Hardening network-map monitoring and connection-state handling.
- Implementing and reviewing on-chain data-storage transaction support.
- Integrating data storage, address data, NFTs, loans, assets, and transaction history into the GUI wallet.
- Improving GUI wallet cache synchronization, cache deletion safety, and Windows file-access coordination.
- Reviewing Rust transaction validation, mempool handling, block saving, and chain-reorganization paths.
- Identifying behavioral inconsistencies between local wallet caches and RPC responses.
- Expanding and reorganizing user documentation for installation, wallets, transactions, validation tools, loans, swaps, NFTs, fees, and data storage.
- Assisting with testing, compilation checks, technical explanations, and project presentation materials.

Codex served as a development assistant. Project architecture, consensus rules, economic design, feature requirements, testing decisions, and final implementation direction remain human-controlled.

## System Requirements

Recommended node requirements:

- Dedicated Internet
- PC / Laptop / Hosted VPS or cloud hosting
- Minimum 16GB memory 24 - 32 GB recommended
- i5 or higher CPU (or AMD equivalent CPU)
- 64 bit processing OS

Contractless uses Falcon signatures and requires 64-bit processing support.

## Networking Requirements

A public Contractless node must be reachable by other peers.

- Dedicated Public IP address
- Open public RPC port
- Router or host firewall port forwarding when behind NAT
- Reliable system time using NTP or another time synchronization service A common default is `pool.ntp.org`.
- One mining node per public IP

## Current Status

Contractless is still under active testnet development. Interfaces, transaction tools, docs, and node behavior may continue to change while the chain is tested.

If you are interested in running a testnet node, start with the installation guide for your operating system, then review the configuration and wallet tools documentation.
