Topic: What are BitCoin Transaction Accelerator? (Read 292 times)

Not really. Of course if it's a specific miner accelerator- VIABTC for example, your block would (if it were to be accelerated) mined by the ViaBTC Pool.

Other than that i don't think there's any way to see it.

I've yet to see a service that actually works with accelerating BTC transactions, I've seen numerous websites and bitcointalk threads offering these services, but it's hard to track and see if someone actually accelerates it, or if they are fishing for donations.

I'm guessing there is no way to check if a transaction has been accelerated, right?

The article linked doesn't make sense, most of the sites only rebroadcast the transaction, which do little to nothing. The most effective way to get it accelerated would be to either:

- Know a miner who can help you out with it
- Either send it with a higher fee, or you can RBF it and send it again. Don't use web wallets, they charge stupid fees for transactions.

50x (or 5000%) higher fee is not a "bit exaggerated" it is wildly overpaying fees.

this is what the site is suggesting:


this is the block that was mined with this "suggestion:
https://www.blockchain.com/btc/block/0000000000000000000fcbab21457c82baeca3df2f7fc7f63c9c7c18f3a0d5e4?advanced=true
if you scroll to the bottom skipping the overpaying transactions you can see that about 20% of the transactions are paying 1 satoshi/byte and more than half are paying less than 20 s/b which makes 50 s/b a crazy fee to pay because it would put it among ~5% of the transactions in that block that are paying extremely high fees!


in fact i dare say this site and other broken tools like it are one of the main reasons for these high fees.

Linking an unreliable/outdated source isn't good for beginners, there's a lot of inconsistencies in that article.

First paragraph: the maximum block size isn't limited to 1MB,
it could reach more than 1MB if there were more SegWit transactions in that particular block (theoretically <4MB).
Wiki: Segregated_Witness
History? : 2.25MB block height 540107

Second Paragraph: They aren't adding "extra fee" to increase the chance of confirmation, they are charging "service fee" for their paid service which is a simple prioritisetransaction "txid" 0.0 command.
If they want to "increase their mining fees & reward", they can just mine normally because it will automatically select the transactions with the highest fee.
It's a mix of public service and taking advantage of other people's mistakes.

Sure they do. Problem was that all "free slots" on these accelerators were always used already. So they offered sometimes premium service to buy slot which is weird because it can be also done with standard transaction but with higher fee.
Overall its interesting idea and concept, but free slots are not possible to get while network is congested and there is huge demand.

agree, creating a new transaction with higher fee would be better option
in fact, when the transaction was dropped, it gives us an opportunity to bump the fee when it wasn't RBF opt-in
simply rebroadcasting the transaction won't do you any good if the current minimum network fee is still high

Most wallets support RBF.
At least the proper wallets. So no web wallets or other kind of custodial wallets.

Good desktop wallets (e.g. Core, Electrum, Wasabi) have the option to enable RBF. Same applies to mobile wallets.




The standard time a transaction is being held in the mempool is 14 days.
If a transaction does not confirm within that timeframe, it probably would be wiser to create a new one with a higher fee instead of rebroadcasting it (especially if the RBF flag is not set).

If people don't have urgent bussiness stuffs or deposit to fight against margin calls, ie., they can move their bitcoin at 1 satoshi/ byte, so they don't really need bitcoin transaction accelerator.
Fees rise, then fall, so I don't think we should waste hundreds or thousands of satoshis, because we always have good days to move coins cheaply, even at 1 satoshi/ byte.
Bitcoin Transaction Fees - Everything in one

Using an RBF supported wallet is always a better option but still there are many wallets which do not allow RBF transactions and the transactions get stuck because of low feen and it can't be bumped. These accelerators are actually useful in those cases.

When i was a crypto newbie i got my bitoin stuck and i used viabtc to boost the transaction and it did work but once i detect that the fault is from the transaction fee i most times adjust to normal and not too low fee

The article is spewing bullshit.

Its simply not true. Rebroadcasting a transaction is actually pretty useless if your tx is already known by a good amount of nodes, and it certainly doesn’t improve it being added faster. I have yet to see any evidence that this is the case.

I do not know any free transaction accelerator then ViaBTC, and I use it in past very successfully. But they are limited (in free version) in number of transaction per hour, and fact that they will not accept any transaction which has a fee lower then 10 000 satoshi.

As AdolfinWolf say, it is better to avoid any wallet that is not allow RBF(replace by fee), which is a very useful option if the transaction gets stuck. It is important to emphasize that this option should be enabled before sending the transaction.

What every user should do before sending a transaction is to check current status of network fees and mempool size. In that way you can adjust your fee according to your needs, for fast confirmation you will need to pay the highest fee, and if you can wait then you can adjust fee and reduce transaction costs.

Some users say that they exaggerate a bit, but I sometimes use this site because they show in simple way how much fee you should pay and predictions for confirmation in blocks / time. https://bitcoinfees.earn.com/

In short, if you want to avoid using transaction accelerators pay attention to what I mentioned

Most of these accelerators you find online are actually NOT ran by miners, but rather just by someone who's looking to make some adrevenue money.

Their sites, or "accelerators" do nothing but either rebroadcasting your transaction, or trying to add them to the VIABTC accelerator (which is nearly impossible, as they're usually filled the second the next hour goes in. (Or that's how it used to be at least.)

And BTC.COM is actually ridiculously expensive. A much better and cheaper solution would be to stop using f*** web wallets, and use a wallet that actually has RBF & segwit.

You guys have observed that whenever the no. of Bitcoin transaction increases, because more crypto users are trading bitcoin, the block size reaches to 1MB i.e its maximum limit and it results in the Congestion in network, which results into transactions getting delayed, and they stay in mempool (waiting line or queue) for the confirmation. There is a solution to this problem, which is pay an extra fee and accelerate the transactions.

What is Bitcoin Transaction Accelerator?

Bitcoin Transaction Accelerators are the enhancers, which are an off-chain service, accepting an extra fee to include a particular transaction in the upcoming Bitcoin block deliberately in order to get sufficient confirmations. These accelerators are run by none other than the miners themselves as their intention is to get higher block mining fees and rewards.

Back in 2017, the Bitcoin network was processing more than 450,000 transactions per day, which created network congestion, as the miners were prioritizing transactions based on the transaction fee. The ones with a low transaction fee were stuck in the mempool. In times like this, Bitcoin accelerators can become handy. Example: Antpool transaction accelerator

Here is a list of top bitcoin transaction accelerators -

• ViaBTC - This service started in 2017, Their service is free, but limited to 100 acceleration per hour. To use this service, you need to submit your transaction ID and a minimum transaction fee of 0.0001BTC/KB, but they give priority to those transactions, which are ready to pay higher fees then others.
• BTC.com - It's not native for BTC.com to run acceleration service but they do so with cooperation from other mining services. In order to avoid network congestion and delay in transaction confirmation, you can use the accelerator developed by BTC.com. You can increase the transaction confirmation probability to 75% in 1 hour and 98% within 4 hours. The fee may vary depending on the network congestion on the blockchain. To get the free estimate, you can sign up and keep in mind that it is not refundable because the acceleration is non-retractable.
