What RoninDojo does

RoninDojo is an open-source, community-driven Bitcoin full-node and privacy-tooling project founded in 2019 by Zelko and S2l1. It targets self-sovereign, privacy-conscious Bitcoin users ('Bitcoiners') who want to run their own validating node and integrate with the Samourai/Whirlpool coinjoin privacy stack without trusting third-party services. The project is unfunded by venture capital and is operated as a volunteer-driven initiative.

The core product is a fork and reimplementation of Samourai Wallet's Dojo backend, packaged together with RoninOS (a customized Linux distribution), RoninUI (a web-based node management interface), and RoninCLI (a command-line interface). The stack supports multiple hardware platforms including RockPro64, Rock5b, and Raspberry Pi. Technical differentiators include Whirlpool CLI for coinjoin participation, the Soroban P2P coordination network (a decentralized alternative to Samourai's coordinator), PandoTX for transaction construction, and the Boltzmann analyzer for transaction entropy and privacy scoring. A major v3.0.0 rewrite (April 2026 beta) extends compatibility to x86 server hardware.

The business model is donation-based with no formal pricing or commercial go-to-market. The only historical commercial channel, the Tanto plug-and-play hardware node, was discontinued following the April 2024 indictment of Samourai Wallet's founders, which also triggered a material team contraction, migration of development infrastructure to a self-hosted Tor-only repository, and a defensive strategic pivot toward a Samourai-independent privacy stack. The project has no disclosed revenue, no enterprise customers, and no paid contracts.

Revenue model

1. Hardware Sales: RoninDojo sold the Tanto, a pre-built plug-and-play Bitcoin node in a custom enclosure. Released December 2021, made 3 modifications to the enclosure design. Hardware sales were discontinued as a product decision aligned with roadmap to focus on software. Support for Tantos continues through end of 2025.
2. Software Downloads: RoninDojo software (RoninOS image, RoninDojo scripts, RoninUI) is freely available as open-source download from their website and via Tor for privacy-conscious users.
3. Donations: The project operates without venture capital funding. They accept donations via their donate page and PGP-signed donation addresses. Defense fund support for Samourai Wallet was facilitated.

Core offering

RoninDojo is an open-source, self-hosted Bitcoin full node project that packages privacy tooling and coinjoin coordination into a plug-and-play stack. It runs RoninOS on supported hardware and integrates the Samourai Wallet privacy stack, including Whirlpool coinjoin, the Soroban decentralized P2P coordinator, and the Boltzmann transaction analyzer, allowing individual users to operate a sovereign Bitcoin backend without relying on third-party services.

Product overview

RoninDojo is a privacy-focused Bitcoin node project providing a complete self-hosted infrastructure stack. The core offering consists of RoninDojo (the Bitcoin node software stack), RoninUI (web-based management dashboard), RoninCLI (command-line interface), and RoninOS (custom Linux operating system). The ecosystem also includes the RoninDojo Tanto hardware appliance. These products work together as an integrated system: RoninOS runs on hardware, RoninDojo provides the Bitcoin backend services, and users interact through RoninUI or RoninCLI. The system is specifically designed to power Samourai Wallet with advanced privacy features including Whirlpool coinjoin, Soroban P2P transaction broadcasting, and Boltzmann transaction analysis.

Products and services

• RoninDojo (core node software) Open-source Bitcoin full node software that bundles Dojo backend functionality, Whirlpool coinjoin tools, Soroban P2P coordinator, Boltzmann analyzer, Electrs, Fulcrum, and indexer services for individual Bitcoin users seeking self-custody and transaction privacy.
• RoninUI Web-based graphical management interface for the RoninDojo node that allows users to install, configure, and monitor node applications and Whirlpool coinjoin activity from a browser.
• RoninCLI Command-line management tool for the RoninDojo node, providing advanced users with administrative control over node operations, applications, and configuration.
• RoninOS Custom Debian-based operating system purpose-built to run the RoninDojo node stack on plug-and-play single-board computers, isolating Bitcoin node operations from general-purpose computing environments.
• Tanto plug-and-play node hardware Single-board computer sold as a dedicated plug-and-play hardware target for running RoninOS and the RoninDojo node stack; later discontinued as a commercial product line.

• Samourai WalletcoreStrategic or Co-development Partner · 1 December 2021RoninDojo was created by Samourai Wallet users for Samourai Wallet users. It runs a fork of Samourai Wallet's Dojo backend software. The teams communicated closely and became close friends. RoninDojo was endorsed as the official hardware partner for the Tanto, marketed as the best way to run plug-n-play Dojo and backend for Samourai Wallet. Following the April 2024 indictment of Samourai Wallet founders, RoninDojo continued supporting users while adapting infrastructure to protect the community.

Direct peers

• Umbrel: Popular home-server OS (umbrelOS) with one-click Bitcoin node and Lightning app marketplace. Competes for the same self-sovereign-individual segment with a much broader app ecosystem than RoninDojo's Bitcoin-privacy focus.
• myNode: Software and hardware for running a self-hosted Bitcoin and Lightning node. Directly comparable plug-and-play node solution with similar target user (non-technical Bitcoiners seeking sovereignty), though less focused on privacy tools.
• Sparrow Wallet: Desktop Bitcoin wallet focused on security, privacy, and connectivity to user-run nodes. Targets the same sovereignty-focused user segment as RoninDojo and supports multiple coinjoin implementations including Whirlpool.
• Samourai Wallet: Privacy-focused Bitcoin wallet that originated the Whirlpool coinjoin and Dojo backend architecture that RoninDojo forks and self-hosts. Was RoninDojo's core integration partner and the primary user-facing client for Dojo nodes.
• Wasabi Wallet: Open-source Bitcoin privacy wallet offering WabiSabi coinjoin coordination. Competes directly with RoninDojo/Samourai in the on-chain Bitcoin privacy segment, though it uses a centralized coordinator model rather than self-hosted nodes.
• Start9: Maker of Embassy and StartOS for self-hosting Bitcoin nodes and privacy-respecting services. Closest comparable in productizing plug-and-play sovereign infrastructure for Bitcoiners, similar go-to-market via hardware-plus-OS bundle.
• Nodl: Pre-built plug-and-play Bitcoin node hardware appliances with integrated software stack. Direct competitor to RoninDojo's discontinued Tanto product in the self-hosted Bitcoin node hardware segment.
• JoinMarket: P2P marketplace for Bitcoin coinjoins where makers earn fees by providing liquidity to takers. A comparable trust-minimized, open-source Bitcoin privacy infrastructure project targeting technically sophisticated self-sovereign users.

Emerging players

• BTCPay Server: Open-source, self-hosted Bitcoin payment processor that includes a full Bitcoin node. Adjacent self-sovereign infrastructure serving merchants rather than privacy-focused individuals, but shares the no-need-to-trust-third-parties ethos.

Broad incumbents

• Blockstream: Established Bitcoin infrastructure company operating Liquid, Lightning, satellite, and mining products. Operates broadly in the Bitcoin infrastructure space where RoninDojo competes at the consumer-node niche.
