Bitcoin's lightning network achieves this by using the base transactions stored on the blockchain only as a fall-back, so that many transactions can be performed without needing to be globally synchronized. Only in the case that a partner fails to follow the established rules of engagement between nodes, a transaction must be created on chain, to "force" the correct outcome. https://en.wikipedia.org/wiki/Lightning_Network https://en.wikipedia.org/wiki/Lightning_Network
