The founder of the etherium, Vitalik Buterin in his tweeter announced Sharding, a way to scale the crypto currency network, which will lead to enormous changes.

Sharding is one of the ways to scale the network, suggesting that, in addition to the main block, separate "fragments" will be created, in which thousands of users can work. All data from them will be transferred to the main chain of blocks, but the information will be received in a reduced form. In this case, each subsystem can have some differences.
