Bismuth

Bismuth is a Python-based proof-of-work cryptocurrency and smart-contract platform. Its node software validates blocks, maintains the ledger, communicates with peers and mines; the repository also documents wallet and explorer support, a read-only REST API, and a private development chain.

Practical overview

When it fits

Use Bismuth when you need to operate or develop against its proof-of-work network, inspect ledger data through its documented API, or work on Bismuth-specific applications. Use regnet for the private development-chain workflow described by the project.

Who it is for

  • Operators running a Bismuth blockchain node.
  • Developers building Bismuth wallets, explorers or smart-contract applications.
  • Contributors working on blockchain networking, mining or node components.

Documented uses

  • Run a node that validates blocks and maintains a ledger.
  • Read node, block, balance and transaction data through the REST API.
  • Develop and test on the private regnet chain.
  • Build Bismuth-specific wallets, explorers and smart-contract applications.
Before you choose

Requirements & limits

  • The node quickstart requires Python 3.8 or later.
  • The REST API is read-only and opt-in; it runs alongside the legacy socket protocol.
  • Regnet has no peers and no real proof of work, so it serves a different purpose from mainnet.
  • The repository recommends tagged releases for production because main may be ahead of what is network-validated.
  • The repository specifies the GPL-3.0 license.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Install and start a Bismuth node

Set up the documented Python dependencies and start the node on mainnet.

Before you start

  • Python 3.8 or later
  • The Bismuth repository and its requirements-node.txt file

Steps

  1. Install the node dependencies with pip3 install -r requirements-node.txt.

  2. Start the mainnet node with python3 node.py.

  3. Stop it cleanly with python3 node_stop.py.

Expected outcome

The documented quickstart starts a Bismuth mainnet node and provides a command to stop it cleanly.

Guide limitations

  • The repository advises using a tagged release for production; main may be ahead of what is network-validated.

Source-based practical guide

Start a private regnet development node

Configure and run the documented private, instantly mineable development chain.

Before you start

  • Python 3.8 or later
  • The Bismuth repository, including tests/config_custom.txt

Steps

  1. Copy tests/config_custom.txt to config_custom.txt.

  2. Start the development node with python3 node.py regnet2.

Expected outcome

The repository documents a regnet node with a REST API on port 3031 and a socket on port 3030.

Guide limitations

  • Regnet is described as having no peers and no real proof of work; it is a development chain, not mainnet.
