Title: unconfirmed transaction is done from sender?
Post by: Potent on December 21, 2017, 11:15:11 PM
I sent some coins to another one 3 days ago but it is still unconfirmed.
Bitcoin network hadn't any fork during these 3 days.
Is the transaction done from my side?
Can i undo this transaction?

It will be returned to your balance if it won't get confirmed. I'm waiting 5 days on my own already.

When?

Someone told me your transaction will remain in limbo util gets confirmed.
He said your BTC is in limbo and never back.
He said No one can undo any transactions.

Your transactions which are unconfirmed are stored in the mempool of the nodes in the network. For each of the nodes, they have different time limit for transactions to be kicked out or "forgotten" by the network and it would be as if it has never happened before. Once the majority of them has excluded it out of their mempool, you can send a new transaction.

It is true, that your transaction won't be dropped if someone rebroadcasts it continually though. It is possible to replace unconfirmed transaction, pretty easily in fact. It is very hard to undo a confirmed transaction, unless you have loads of hashpower.
