We present Accept, a simple, asynchronous transaction system that achieves perfect horizontal scaling. Usual blockchain-based transaction systems come with a fundamental throughput limitation as they require that all (potentially unrelated) transactions must be totally ordered. Such solutions thus require serious compromises or are outright unsuitable for large-scale applications, such as global retail payments. Accept provides efficient horizontal scaling without any limitation. To that end, Accept satisfies a relaxed form of consensus and does not establish an ordering of unrelated transactions. Furthermore, Accept achieves instant finality and does not depend on a source of randomness.
