 :D Hi think that is a very stupid questions, however: Is possible to mine a specific transaction for fast confirmation in the chain?

You can push a specific transaction here http://eligius.st/~wizkid057/newstats/pushtxn.php

If you can guarantee that you mine the next block (basically have 100% hash rate power), then you can choose to include whatever transactions you want up to the 1MB block size limit. And because you will have to have 100% hash rate power, you need not fear that block being orphaned.
Probably cheaper just to slap an irresistible fee on it, and the miners will be hand bags at dawn over it.

Yes, it is possible.

What about altcoin? I mean, if I know the transaction ID and other stuff, can I mine only that transaction?

In theory yes, but it relies on you being able to mine a block which the transaction could contain so that it can be confirmed.

A specific transaction can only really be mined by a miner who includes the transaction in a block that they mine.  So you would need an amount of hash power which allows you to mine loads of blocks, which you won't be getting any time soon (and if you set a fee too low, miners will have no economic reason to include your transaction so it won't happen).

You're probably thinking of downloading some miner on your computer and just mining your transaction specifically, but that's kind of impossible.

There are services that try to include your transaction, like ViaBTC's transaction accelerator (https://www.viabtc.com/tools/txaccelerator/), but they're always limited and, if they're free, always have an agenda.  You'd be best off just paying a good fee.

Obviously altcoins aren't all the same, but the systems are usually very similar to Bitcoin.

So you might be able to, but for practical purposes, no.

miners are doing exactly this!
you see all the transactions in the memory pool then among them choose the ones you like, for example they choose those transactions that are paying higher fees. and big mining pools such as F2Pool will ignore any transaction that has lower fees than a certain level even if there is no other transaction left in the mempool other than 1.
in other words they will mine empty or half empty blocks instead of including low/no fee transactions even if mempool is empty.

you don't mine transaction, you include them in the block you find, but you need a considerable hashpower to do that, with altcoin that have a small hash is surely more feasible to do it in solo

i see that your nick is centurion, a presume you want to do this on the altcoin called centurion x11, you can try to do it with a baikal x11 asic which has enough hash to take on the chain

This is why I am saying these miners are manipulating the supposed Spam attack in their favor. They "manage" the mempool in such a way to increase the impact that these Spam attacks are having on the confirmation of these tx's. They just need to mine around these problems and wait for the higher fees to bump their profits.

Rich people will always benefit the most from a mining scenario like this. ^grrrrrrr^

Thank you for the perfect reply  ;D

These was the reply that i was hoping. All is more clear, so a block is capable of lot of transaction. When i made a transaction it going to be "batched" in the next generate block and when he will hased by the miner, and reach the level of necessary share, it be confirmed.

The only method to fast confirm the transaction is have lot of power for mine the block.

Thank you for the reply man :)

No you can also get faster confirmation if you put high fees on your transactions because most of the miners prioritized the transaction with respect to fees it have.

Yes this is possible, there are many sites that support you increase the speed of bitcoin transactions. However, all sites limit the number of transactions per hour, here, I would recommend to you this site https://www.viabtc.com/tools/txaccelerator/
This is a speeding site for your transaction, so it's easy to use. However, only 100 transactions are accepted per hour, you need to be the first to be able to be supported.
