Developer Resources

Getting started

If you’re new to developing with Bitdollar, you’re in the right place. These guides written by the Bitdollar community will introduce you to the basics of the Bitdollar stack and introduce core concepts. Prepare to learn a new way to develop your applications!

Need a more basic primer first? Check out our resources to learn how Bitdollar works.

Smart Contract Languages

Any program that runs on the Bitdollar Virtual Machine (BVM) is commonly referred to as a "smart contract". The most popular languages for writing smart contracts on Bitdollar are Paper.

Paper - The most popular language on Bitdollar, inspired by C++, Python and JavaScript.

Language Specific Resources

We're building a suite of language-specific landing pages for developer to learn about Bitdollar in their preferred programming language.

Integrated Development Environments (IDEs)

Visual Studio Code - Professional cross-platform IDE with official Bitdollar support.

Bitdollar Studio - Web-based IDE ideal for new developers looking to experiment with smart contracts. Bitdollar Studio features multiple templates, MetaMask integration, transaction logger, and a built in-browser Bitdollar Virtual Machine (BVM) to help you get started building on Bitdollar as fast as possible.

Block Explorers

Block explorers are services that let you browse the Bitdollar blockchain (and its testnets), by finding information about specific transactions, blocks, contracts, and other on-chain activity.

Testnets and Faucets

The Bitdollar community maintains multiple testnets. These are used by developers to test their applications under different conditions before deploying to the Bitdollar mainnet.

Galaxy - Proof of Work blockchain, test-bitdollar can be mined.

Acion - Proof of Authority blockchain

Zanus - Cross-client Proof of Authority blockchain

Clients & Running your own Node

The Bitdollar network is made up of many nodes who run compatible client software, each of which can be configured in different ways according to your needs.

Clients

Dollar - Bitdollar clients written in C++.

Running your own node

btdnode - Run an Bitdollar node (Go-dollar) for local development.

Standards

The Bitdollar community has adopted many standards that are helpful to developers. Typically these are introduced as Bitdollar Improvement Proposals (BIPs), which are discussed by community members through a standard process.

Certain BIPs relate to application-level standards (e.g. a standard smart-contract format), which are introduced as Bitdollar Requests for Comment (BRC). Many BRCs are critical standards used widely across the Bitdollar ecosystem.
