Negative balance on wallet

[AmirSolo]

hi, sorry if i made the post in wrong topic. i've seen some bitcoin address's on blockchain.info airpone.com and  that has negative balance like -1.2 btc or -0.05
how it work's like this?

for example :
https://apirone.com/btc/address/1GqcMJn3xsJ1yboigQ4gbHopN4EMTYDrsK

Probably a bug in their (apirone.com) system.
Blockchain.com/info doesn't show negative balance from that address: https://www.blockchain.com/btc/address/1GqcMJn3xsJ1yboigQ4gbHopN4EMTYDrsK

Probably, it has something to do with their node(s),
blockchain.com reads that the address was used in 331 transactions while in apirone, it has only 299.
I didn't dig-up more info but that should explain the inconsistency in the balance.

As far as I know, it's not possible to have a negative balance in your Bitcoin address.
If you search in a more reliable block explorer the balance is zero.

This idea of negative balance is a nonsense in blockchain, because you can just create a new address.

Banks can give you a negative balance, but blockchain can't.

To be quite true, the bitcoins are stored in the blockchain. In order to spend those coins, you need to sign with your private keys. The wallet and block explorers are just a graphical user interface which helps you to view the balances as they get updated over the nodes.

Whenever you are trying to spend the coins, the outputs and inputs will be checked and verified by the nodes before the transactions are being added to the blockchain. If the input value is less than output value, the transaction is rejected. Hence you can never have a negative balance.

Negative balances can be created only when the inputs are less than output value and such transactions are being confirmed which isn't really possible.

Here is the code to prevent transactions that has negative balances

Code:

const CAmount value_out = tx.GetValueOut();
    if (nValueIn < value_out) {
        return state.Invalid(ValidationInvalidReason::CONSENSUS, false, REJECT_INVALID, "bad-txns-in-belowout",
            strprintf("value in (%s) < value out (%s)", FormatMoney(nValueIn), FormatMoney(value_out)));
    }

Like as Heisenberg_Hunter said, an address can have negative balance when they send more bitcoin than they hold on the address. This transaction will never be confirmed. Similar issue can be found here- https://bitcoin.stackexchange.com/questions/53562/negative-bitcoin-balance
