Hello
i have small farm 10 Antminer S9.. i want to ask how to confirm a bitcoin transaction manually with my antminers ?
You can include your own transactions in a block and hope that you are the one to solve that new block and get the reward for it to be counted as a confirm within the network, otherwise it's not going to confirm. This works if you are in charge of building/including all the transactions in a block however it would be a different story if you are in a mining pool wherein they prioritize transactions with the most fees paid into them.
coz i heard there's will be update to bitcoin network so i can manually approve by point my antminers s9 to thix tx !
You already can, you just have to pray hard that you will be the one who will solve the next block in order to get the confirmation.
