About Clobber

Clobber is a hosted central limit order book. A team that is building a market (a prediction market, an exchange for its own points or tickets, a swap corridor) rents the matching engine, the double entry ledger, the durability and the failover from us, and spends its year on the market itself instead of on exchange plumbing.

What we believe an order book owes its operator

Determinism. The engine is a pure, single writer state machine over an ordered log. Replaying the log reproduces the state byte for byte, and that one property does four jobs: failover, audit, migration, and the oracle the engine's own tests are checked against. The whitepaper makes the argument in full.

The ledger is inside the engine. Every hold, fill, fee and payout is a double entry written in the same step as the match, in integers, conserved at write time. There is no reconciliation job, because there is nothing to reconcile. Fundamentals states the rules.

Correctness is demonstrated, not asserted. The same orders run through a second, independent engine and the two are compared. Integrity publishes the run, with the commit and the machine it ran on.

How it is sold

Hosted, always. Every environment is pinned to one cell in one region, a sandbox is free and self serve, and production is opened with a person. The plans are on the home page, what an acknowledged order survives on each of them is on reliability, and the commitments are in the Service Level Agreement.

The company

Clobber is a product of ALIEN SOFTWARE LLC, a Wyoming limited liability company, United States. The API is documented in full at docs.clobberhq.com, because the contract was written before the code that implements it.
