Where/How much of ledger is stored for various coins?
« on: August 28, 2017, 06:11:32 PM »
Anyone with knowledge about the technology behind blockchain cryptocurrency can explain how the decentralized ledger is stored and how much on each coin?  One would think that if the whole ledger were on each coin it would get bogged down very fast and each coin would be a huge file size.  I know there are 'blocks' but does this mean that a particular coin just contains the last block?  How exactly does it work?   Are all blocks on a given coin updated constantly or only when a transaction is made?  Is the same system used for all coins or does it differ from coin to coin?  Any blockchain experts out there?

Every time you wihdraw or transfer money to your wallet, it's recorded in a "book". When you transfer money, the system uses the network to check if you actually have this amount. The system firstly counts all incoming operations and then substracts all the outgoing ones. And if the sum remaining is larger than that you're transferring, the system approves the transfer and records an outgoing operation.

Thanks for the detailed answer. I haven't been able to find similar information either for a long time, and there practically aren't any normal sources. Can I have the source of this information where I could read it?
