Bitcoin Forum

I'm new and have no more experiences in Bitcoin transactions. While some transactions, I'm hearing a bell sound.

1. At what time it comes? When a payment receives to address or first confirmation?
2. Who produces that sound alert? the tx service provider or blockchain itself?

Thanks.

Are you talking about this page? If yes these are all unconfirmed transactions, when a new one is just added to the list there is a sound alert. A different ones when a new block is confirmed.

All transactions are checked directly on official websites or support for hash checking. Each transaction has a different hash code. Here you can check your transaction details. For Bitcoin, you only need 1 cofirm to see it displayed in the destination.

I'm not familiar with the bell sound, lol.... I am not new but I maybe have a little time to check transactions that are not mind.
Every transaction you can search in the blockchain and that's it.

For legacy address, I check in this site, https://www.blockchain.com/explorer, and for segwit address, I check in https://chain.so/...
I believe there's a lot of sites to check transactions, just wanna say you can always check in the blockchain.

You can check it on the tx number, you can receive it after the confirmation is complete, the confirmation number is determined on the amount of fees you use. If you want a faster transaction, please check https://pool.viabtc.com/tools/txaccelerator.
Usually producing an alert sound is a service provider, sometimes I don't hear the sound alerts.

It is possibly coming from the wallet software you use. It is just a sound alert for you to know that the transaction were submitted or that it was successful. What wallet software do you use?

I get the same sound from most of the wallet software I use and never even thought about it. It is similar to the alert sounds you hear when you visit a ATM and you withdrawn some money. <I always joke and say it sounds like you won a jackpot on a slot machine>  :P

have you paid some bitpay invoices? when your bitcoin payment gets confirmed on the blockchain, bitpay marks the invoice paid. the invoice page makes a "ding" sound when that happens. sometimes when you pay a really high fee, bitpay will do this as soon as they see the bitcoin transaction on the blockchain. (no waiting for a confirmation)

the bitcoin protocol / the blockchain doesn't make any sounds. :)

Yes, that's it... bitpay.

I have heard that bell sound but it isn't with bitpay, I think blockchain.com wallet does have that kind of feature when you send/receive bitcoin to/from other address.
