# Blockchains

Each blockchain is developed to solve different tasks and to satisfy different needs. The difference in their purposes determines the difference in their scalability limits, levels of anonymity, consensus protocols, transaction types, block sizes, etc. It is also important to mention that each blockchain always can be improved and upgraded in order to expand its capacities in task solving.
