What is a balance for a Bitcoin-Qt/bitcoind address?
Could you please elaborate on the concept of "balance" in the context of a Bitcoin-Qt/bitcoind address? I understand that Bitcoin is a decentralized digital currency, but I'm curious to know how the balance associated with a specific address is determined and maintained. Is it a static figure that reflects the total amount of Bitcoin received minus any outgoing transactions, or does it fluctuate based on network activity? Also, is there a way to check the current balance of an address using Bitcoin-Qt/bitcoind? Thank you for your clarification.
