Abstract: Disclosed is a distributed computer system that includes a plurality of worker nodes that are coupled together via a data communication network to exchange data therebetween, wherein computation by the worker nodes is managed within the distributed computer system. The distributed computer system configured to implement a scheme for mapping cryptographic keys to a specific shard in the distributed ledger arrangement that can be modified by a user worker node and an operator worker node of the distributed ledger arrangement; employ a pricing mechanism for specifying transaction costs that incentivizes user worker nodes to submit transactions that are restricted to a single shard; adopt algorithms specifying internal logic for wallet software that access shards so as to minimise their transaction costs; and execute procedures for reorganizing state databases when shards are duplicated or merged so that subsequent transactions can be maximally executed in parallel.
