Peerloom Labs engineers peer-to-peer applications with zero central databases, end-to-end cryptographic integrity, and absolute user sovereignty.
Split bills and track balances for roommates, road trips, and dinners without third-party companies spying on your financial habits or charging subscription fees.
Your data never touches an AWS/Google Cloud database. The app generates an Ed25519 cryptographic identity locally on your phone.
Every expense and settlement is an immutable, hash-linked operation in your group's private DAG. Reconciles concurrently without merge conflicts.
Verify full cryptographic integrity in one tap. Inspect block hashes, cryptographic signatures, and authoritative state digests directly.
Our greedy debt engine reduces tangled multi-party balances to the fewest transactions using exact integer math, with instant UPI intent handoffs.
How Peerloom Labs achieves real-time peer-to-peer sync without storing unencrypted user records on any server.
No sign-up emails or SMS OTPs. Your device creates an Ed25519 signing keypair stored in hardware-backed Android KeyStore. All operations are signed locally before broadcast.
Inter-device packets sync through open public Nostr relays over secure WebSockets (WSS). All group payloads are end-to-end encrypted with 256-bit AES-GCM. Relays cannot read your expenses.
Every financial value is stored strictly in integer minor units (cents/paise) with BigInteger proportional share distribution. Zero floating-point drift across heterogeneous devices.
