Systems and methods for selectively processing blockchain data
An improved blockchain implementation that reduces application transaction processing bottlenecks for applications that operate on a decentralized network. For example, if an application operating on a decentralized network becomes sufficiently popular, an existing blockchain can be split into the original blockchain and an application-specific chain (or app chain) that includes blocks that only store transactions for the sufficiently popular application.
