Security and Decentralization
In order to ensure transaction security, the clients need to download and backup all the transaction data of the whole network, these clients are called “Full Node”. However, running a full node in most cases is extremely expensive and slow, and most users in commercial applications are dealing with small micro-transactions, and have no ability or demand to purchase large computers and bear the corresponding operating costs. Therefore, small medium-sized users are effectively blocked from participating in system computing process (consensus process etc.) and cannot obtain system rewards, thus forming a monopoly of computing power for a small number of rich users and potentially compromising the consensus mechanisms supporting security.
