A deterministic ledger engine built for speed and correctness for high-throughput balance systems. We serve you with lock-free and nanosecond-level performance.
Why Orbit Ledger?
Stop fighting with database locks. Let us handle the hard part.
Deterministic Ordering
Same inputs produce same outputs. Every time. Per-account event sequencing guarantees consistency.
Correct Balance Transitions
No race conditions, no lost updates. Every credit and debit is tracked with atomic precision.
Zero DB Locking
Database is never in the hot path. Process millions of transactions in-memory, persist in batches.
Unified Output
History + Balance Delta in one atomic payload. Perfect for auditing and compliance.
LMAX Disruptor Core
Built on the same technology that powers LMAX Exchange. Lock-free, mechanical sympathy.
You Own Persistence
We compute. You store. Full control over how and when you persist to your database.

See the Difference
Watch how 5 concurrent threads process the same account
❌ Traditional Database
Each thread waits for lock → Sequential
✅ Orbit Ledger
All threads instant → Batch to DB
The Problem We Solve
1000 Transactions shouldn't mean 1000 DB Calls
| Metric | Traditional DB (1000 tx) | Orbit (1000 tx) | Improvement |
|---|---|---|---|
| DB Calls | 3,000 (3 per tx) | 2 (1 batch) | 1500x fewer |
| DB Locks | 1,000 locks | 0 | ∞ |
| SELECT FOR UPDATE | 1,000 queries | 0 | ∞ |
| Throughput | ~2,000 ops/sec | >4,500,000 ops/sec | 2000x+ faster |
| Latency (p99) | 10-100ms | <1μs | 10,000x lower |
