Newbie question about the speed of the network in 2025.
Suppose I want to monitor with a bot a given long dormant address A, so that if it sends a transactions to some other address B, say tomorrow at 10:09:26, then my bot will also send a transaction to B at the same exact time,so that in the blockchain it is impossible to say which one is earliest.
Is it possible? Can you expnain the mechanism, including the time it takes for a tx to be accepted. Thank you.
All transactions in a block occur at the same time. The time of a transaction is the time of the block it is included in. The time of a transaction is not when it was created or broadcast, though that can influence which block it is included in. One transaction is earlier than another transaction only if it is included in an earlier block. There is no way to guarantee that your transaction is in the same block or an earlier block.
The timestamp of a block is not the time it was added to the block chain, but it is close. It is guaranteed to be within about an hour of the actual time it was added. Furthermore, it is not uncommon for a block to have an earlier time than the block that precedes it.
I'm curious about what you are trying to accomplish. When bitcoins are sent from A to B, why do you also send to B?
