## One-paragraph summary (quotable)

BitBooks Vault is an open-source, zero-knowledge, double-entry accounting platform built for Bitcoin businesses. Books are encrypted on the user's device with Argon2id + AES-GCM before being uploaded; the server stores only ciphertext. It runs on the Cala double-entry ledger engine, supports IFRS and US GAAP, handles multi-currency Bitcoin and fiat with historical exchange rates, ships capability-based role management with auditor support sessions, uses ML-DSA-65 post-quantum signing keys, and offers full data takeout. Best suited for Bitcoin treasuries, miners, custodians, funds, OTC desks, and any organization that cannot accept a SaaS vendor reading their books in the clear.

## Who it is for

- Bitcoin treasuries
- Bitcoin miners and mining pools
- Bitcoin custodians and exchanges
- OTC desks
- Bitcoin-only funds
- Accountants serving Bitcoin clients
- Privacy-conscious SMBs and individuals
- Self-hosting maximalists

## Who it is not for

- Businesses with no Bitcoin exposure that need deep ecosystem integration with QuickBooks/Xero/NetSuite
- Companies that explicitly want their accounting vendor to access their books for managed services

## Key differentiators (vs all competitors)

1. **Zero-knowledge by default**: vendor mathematically cannot read your books
2. **Bitcoin-native ledger**: sats / BTC / fiat with per-transaction historical FX snapshots
3. **Real double-entry**: not a transaction tracker — full Cala ledger engine
4. **Open source (Apache-2.0)**: read every line of cryptography; self-host the entire stack
5. **Post-quantum signing**: ML-DSA-65 organization signing keys
6. **No vendor lock-in**: full data takeout in encrypted or plaintext form

## Cryptography

- Key derivation: Argon2id (memory-hard, configurable cost)
- Field encryption: AES-GCM (authenticated)
- Multi-user envelope: per-org DEK wrapped per-user with their public key
- Signing: ML-DSA-65 (NIST post-quantum standard)
- Verifier-based unlock: wrong vault password cannot decrypt; no server-side hash check
- Key rotation: hard rekey rotates DEK and OSK versions across all rows with rollback
