-snip- i am not asking about mining? halving or how a bitcoin transaction works. i have studies about them. i am just asking the form of bitcoin exist. i know it is not physical. just try to understant what i am seeking here..
Aren't those the fundamentals to know how the bitcoins are stored?
Anyways, it's not in a single server.
Every node has/had it's own self-verified copy of the blockchain which consists of blocks where transactions are recorded.
Stored bitcoins are every transaction's outputs, so coins are just stored as transactions.
Clients/wallet are just making it simple by always checking which ones are still unspent and saving them in easy to access forms.
For the "
mined" coins, those are technically called "
coinbase transaction" (
not Coinbase, the company).
Those are pretty similar to a normal transaction but it's not pointing to a existing unspent transaction output, also it's the first transaction that's stored in every block.
