If a node persists for 90 minutes without any communication, it is considered to have been disconnected from the network and the network will start looking for a new peer node. Therefore, the blockchain network will be dynamically adjusted according to the changing nodes and network problems, without the need of centralized control to make the orga

Blockchain is now an over-valued area, and these overvalued values are unsustainable and will certainly collapse.
Such bubbles have occurred before and may occur again. But if you work in this field for a long time, you will learn to get rid of the eff
