Hi,

I'm curious about the technology behind exchanges.

Does anyone know which type of database they use for user info and balances? What do you personally think would be the best type of database to use?

How would they integrate the various crypto currency wallets into the database?

How do they instantly generate/allocate new receiving addresses?


As far as I know, in a nutshell, they have the regular user accounts database, but they must also have a database that keeps track of balances. Users don't have an actual wallet (they don't run another wallet management program instance for each user), but they are allocated a balance from the exchange's 'global' wallet(s). That is about the extent of my understanding currently (which may or may not be accurate), so I'm hoping someone here can give much more detail. Thanks!
