This reminds me of companies or really any utility that does not keep up with the times.
Can we have instant transactions already?
I guess not.. some promising future that is..
Happened to me for the 2nd time today!!!
i think instant transaction not yet implemented and many people have get trouble with their transaction. this is the big problem for blockchain and i am sure that in future, blockchain will be fast and we can see our transaction is instantly completed but we need a times before we can see this.
Transactions are almost instant. As soon as you broadcast a transaction, it'll only take a couple of seconds before it's in the complete network's mempool.
However, depending on how much satoshi's per byte of transaction you added, you might have to wait a long time before a miner decides to put your unconfirmed transaction into a block (depending on the age of the transaction or the size of the nodes mempool, you might get dropped from the mempool of most nodes before you're added to a block in case you added really low fees).
Getting your tx in a block (1 confirmation) might be pretty fast, but it'll almost never be instant, since only 1 block gets added to the blockchain every 10 minutes (on average).
The lightning network is being developed for "instant" transactions.
