hi
if big transaction was made with high priority fee but didn't confirmed
and this transaction known as high risk
for example if some guys decided to make crime or take ppl as hostages
and they say ok you want us to release the hostages u must pay us 1m in btc
if money was sent with proper fee but didn't got confirmed yet can anybody stop it from being confirmed? or bitcoin transactions conformations are unstoppable?
and also what about tracing the transaction? is it only possible to see from which wallet it has sent and to which wallet and what ip address used? means is enough for the criminal to use some secured vpn and than nobody can stop him or block the money?
because 3 months ago in December when hacker/s has stolen 4700 btc after that bitcoin transactions like halted operations from being confirmed sometimes 72 hours sometimes more, and fee became extremely high for some period of time
that means there are ppl who have control of the transactions and can decide what will happen, how and when no?
thanks for reading

Answer to your first question. Generally 1 confirmation is not a guarantee of a confirmed transaction there are a few reverse miners which can reverse the transactions on the network. However, the rule is that more are the number of confirmations on the transaction the lesser is the chance to reverse it. Almost after 3 confirmations the chances become negligible. Then it comes to tracing ip address. Tracing any ip address related to a private key wallet is certainly impossible so no way to trace the person associated in crime.

i see ok
thanks
was sure that after 1 confirmation transaction becomes already irreversible for good
apperantly was wrong
but what if the person who receive the coins uses smartphone with blockchain app/other bitcoin app installed on phone?
can't blockchain get the mobile device info which the wallet related to and than trace it?

We all know that a transaction only gets confirmation if the miners put it in their block in order to get the fees paid as reward for that. So, the only scenario where a transaction can be stopped or not let pass the chain is if a person/group has access to 51% of all mining power that exists. With that, they can stop transactions from being confirmed as they probably have more mining power than any other miner so they get prioritized because of that, and no matter how large the fees are for the transaction, if they don't want it to get confirmed, they can stop it. But still, it is not 100% sure to happen, but it is possible, and with that much mining power, the chances are very high.

I have no knowledge about your second question for tracing a transaction. So I won't even attempt to answer that. Someone else with more knowledge about that might give you a more clear answer for that.

P.S: I think this discussion belongs to Bitcoin Discussion section as it is not about legality, but about blockchain and Bitcoin itself. You should move it to that section.

i understand tnx
so if miners want to stop transaction which has passed 3 confirmations it nearly impossible for them?
only if it hasn't passed 3 confirnations  they have the ability to stop it from being confirmed?

It's pointless to use bitcoin for crimes. All transactions are tracked in the network and therefore the money can be arrested after the criminals will try to exchange them for Fiat. The use of cryptocurrency for criminal purposes is a fake that is distributed by bankers. They can't come up with convincing arguments because they don't exist.

I'm not exactly sure about how many confirmations it requires to get out of their reach, but yeah, the more confirmations it gets, the more difficult it gets for them to stop it.

But on the other hand, we have Monero and Bitcoin mixer.

I'm not sure if can be stopped or not. As I know we have one confirmation to make sure that transactions. One confirmation is enough to allow that.

Wait what? Miners can't reverse transactions. Bitcoin transactions are uncensorable, meaning no one can voluntarily stop them nor reverse them. There is only one way to "stop" a transaction from happening, and that's by respending an (unconfirmed) input with a higher fee, praying that the latter transaction will get confirmed first -- also known as double spending.

Bitcoin transactions are traceable through the blockchain, yes, but there are ways to cover your tracks.

There is no way to stop a transaction if the confirmation initiated and I think it is impossible to reverse a transaction even with one confirmation.If that transaction is set with high priority fee then there is no chance to get stuck at all. Shocked

It can reverse the by the network if the confirmation didn't made. If the confirmation starts as 1 or more than that. You will not be able to stop the transaction for sure.
Mempool seems already empty and if you have 5sat per byte in the transaction.
It will be confirmed with in with in 30 mins. Some may add 1sat/byte that is not enough to complete the network faster.

It's inappropriate to say that the network reverses it. Bitcoin transactions were designed to be irreversible, and they are; these transactions simply sit in the mempool (each node has its own mempool) until they're trashed after a period. But yeah, it's almost impossible for such a thing to happen under the current network load, unless you don't pay a fee at all, maybe.
