Who we are

Infrastructure that answers to you

BitDigo is a builder and sponsor of open-source, Bitcoin-native software. We fund and maintain the foundational architecture behind a new class of enterprise tooling — where the user holds the keys, the data lives on relays you choose, and payments settle instantly over Lightning.

Data sovereignty

Your records live on Nostr relays you control and sync through local-first storage. Export, migrate, or self-host at any moment — with no permission required.

Instant, near-zero-fee payments

Bitcoin over the Lightning Network settles in seconds. Non-custodial by design — BitDigo never holds your funds, and we never take a cut of your revenue.

Open source, MIT licensed

Every repository is public. Fork it, audit it, ship it. We build in the open because verifiable software is the only trustworthy software.

The ecosystem

One protocol. Four production fronts.

A connected stack: a social client, native mobile apps, a business operating system, and the core library that powers them all.

Web v0.6.x

BitOS — Nostr Social Client

A local-first social platform: live timeline, short-video reels, a full meme & video studio, end-to-end encrypted chats with group calls, Lightning zaps, and public communities. Relays are the backend; the private key never leaves the browser.

Native v0.1.0

BitOS Native — iOS & Android

SwiftUI and Jetpack Compose clients sharing one Kotlin Multiplatform business core and a C++20 media timeline. Keys live in the Keystore and Keychain — never on a server.

  • Kotlin Multiplatform
  • SwiftUI
  • Compose
  • C++20

Business OS v1.5.4

BnOS — Point of Sale

A decentralized POS and business operating system: product grid, kitchen display, inventory and recipes, memberships, analytics, and payments by cash, Lightning, or local bank QR — split however the customer wants.

The protocol

What is Nostr?

Notes and Other Stuff Transmitted by Relays. An open protocol for censorship-resistant, portable identity and data — no company, no sign-up, no permission. Everything BitDigo builds speaks it natively.

Your identity is a keypair

You generate a public/private key pair. The public key is your permanent, portable identity across every Nostr app; the private key signs everything you publish and never leaves your device. There is no account to create, no email to verify, and no company that can deactivate you.

  • Works across every Nostr client
  • NIP-07 browser extensions for signing
  • Hardware-backed on BitOS Native (Keystore / Keychain)

FAQ

Questions, answered

What exactly does BitDigo build?

BitDigo builds and sponsors open-source, Bitcoin-native software: the BitOS social client for web and native mobile, BnOS — a decentralized Point of Sale and business operating system — and @bitos/bnos-core, the shared TypeScript foundation underneath both. All of it speaks the Nostr protocol.

Is it really free? Where's the catch?

It is MIT licensed and free to use, self-host, and modify. There are no transaction fees on your payments and no monthly subscription. Because the software is open and non-custodial, there is no commercial model that depends on holding your data or your funds — which is precisely the point.

Do I need a bank account or a custodian?

No. Payments settle directly on the Bitcoin Lightning Network to a wallet you control — LNbits, Alby Hub, Blink, a Lightning Address, or any wallet compatible with Nostr Wallet Connect. BitDigo never holds your funds at any point.

How does offline mode work?

The stack is local-first. Data is written to on-device storage (IndexedDB via Dexie) before anything else, so sales and records continue to work with no connection. When you come back online, signed events sync to your relays automatically — and no sale is lost.

How is my data protected?

Sensitive data is encrypted client-side with NIP-04 and NIP-44 before it is published, so relays store ciphertext they cannot read. Media uploads are hash-verified and had their EXIF metadata stripped. In the native apps, private keys are stored in the Android Keystore and iOS Keychain.

I'm a developer — how do I start?

Head to github.com/bitoslabs, fork a repository, and open a pull request. Each repo ships with its own setup instructions, documentation, and test suite. New contributors are genuinely welcome.
