How to handle memory and processor limitations of nodes in blockchain

0 votes

Blockchain uses distributed ledger to store blocks of transactions. So all the participant nodes will have to maintain a ledger to keep the same copy of the chain of blocks.

In future, there will be more and more transactions, then 
*how is data load managed at each node?* 
Some of the participant nodes might have limitations in memory and all, so 
how it is managing properly for its smooth working? 
Also some of the participants like Mobile devices may not have much processing power compared to other systems.

How does Blockchain manage these situations effectively?

Yes, that's a valid concern. The Bitcoin blockchain is many gigabytes large. Thus, if you want to do a payment on a mobile device, for example, your mobile device will need some other way to verify the number of coins in your account and others' accounts because it can't download the entire Bitcoin blockchain. To my understanding, there are nodes that do store the entire blockchain and you can simply ask those nodes that you trust for the current number of coins in certain accounts. There is an element of trust here, but if you don't trust anyone, then you need to download the entire blockchain yourself
