Hey everyone in the Bitcoin forum,
Do you think that allowing users who sent out transaction which is unconfirmed is able to cancel that transaction is a good thing?[/quote
I will say no And my reason is simply it will affect the mining companies. Because it will lead to millions of people canceling transactions daily. And scamers will have more open space to come into the system. So it's shouldn't be implemented.
Why do you want this to be applicable? This will be like reversing a transaction and that will probably harm the grace of Bitcoins that once sent, it cannot be recovered.
i personally think that bitcoin should implement this Feature, like if you sent out an transaction to the wrong address you can quickly cancel it before it gets confirmed which will save lots of trouble for some.
You should not send it to wrong address only at the first place.
There might occur scenarios where, after gaining some trust between parties, one of them might make wrong use of the feature you are asking about.
Every transaction gets recorded in the blockchain and in order to removed that transaction, you will need to tamper that block for which work is already in process by the miners.
