New transaction accelerator on the market - mempool.space

[Pmalek]

I also doubt anyone that knows ViaBTC free accelerator will want to use any paid accelerator.

Not necessarily. ViaBTC being free is a big plus. But many people know about it, which makes it the go-to place for free transaction acceleration. I am surprised that you have noticed a shorter queue on ViaBTC considering the current congested state of the mempools. Damn Ordinals! Also, if it's true that Mempool.space has partnered with Foundry as the pool that includes the transactions in their blocks, you will get a quicker confirmation since Foundry has more hash power and finds more blocks than ViaBTC. That's an advantage if the unconfirmed transaction is time-sensitive.

...so there are times when there are simply no tx out there that match the requirements, as for the next block issue, it happens when ViaBTC has really bad luck and is not getting enough blocks spread across the day, they offer 100tx every hour but sometimes they don't mine a block for 6-7 hours, so not to fill the whole block with cheap tx they postpone a few of them to the next one, I read once something about a 500 cap but don't know how accurate that claim was, probably it's more about size than raw numbers.

I experienced this one when i accelerate my transaction on monday it really take how many hours before my transaction got a confirmation. Checking the last few blocks, it looks like Viabtc doesnt get one, a 1:10 ratio is not even possible, its usually the Foundry, Antpool, and others.

Knowing that 2000 is the average number of transactions in a block then they cater 100 free tx every hour, it could have downside for their Pool. Either they lower the accepted free txs every hour, say 50-80 only, have a cap for free txs in a block, or they stop their free acceleration service.

I have registered since more than a week. This is what I am still seeing as I quote it in a text before. This is the screenshot:



Although, I do not need a paid accelerator, I will still prefer to always use ViaBTC. My transaction will have 18.5 sat/vbyte segwit transaction, not having unconfirmed parent and not more than 500 bytes. I can wait for the transaction to get confirmed. It was only ones that the transaction got confirmation like 12 hours after I submitted my txid, it has gone back to as usual as the transaction will be confirmed in the next block that ViaBTC mine if successfully submitted. It is taking not more than 3 hours, but it depends also.

It is still 100 transactions. ViaBTC has not stopped its free accelerator service.

The acceleration service is have used is viabtc for free it works perfectly for me but that is only when your transaction fee is less than 40 sat/byte it was share in our local board by @Charles-Tim.
The network congestion is really getting out of control, maybe when I am having issues towards confirmation I will also try their free acceleration service as well.

Yeah it is pretty ridiculous lately. I can’t move my damn sig payments for cheap. They are stuck in my wallet unless I pay $10-20 to move my damn funds. Electrum don’t even let me broadcast my transaction telling me that i am a cheapfuck who needs to raise the damn fee because greedy fuck miners say so or else they ain’t broadcasting my shiet. The devs should find a solution or bitcoin will end up way worse than legacy banking. At this point swift is cheaper and faster than btc. Wtf?

I ain’t paying you no more than 10sats/byte you greedy fukz

[Charles-Tim]

It is not the miners that did not let you to be able to use low fee, it is how the mempool is. Presently, nodes are rejecting transactions with fee rate of 10.7 sat/vbyte or less. As the mempool is becoming congested, so the purging will be getting higher.

I don't understand the purpose of the waiting list. Just allow the people to create their accounts. The more users you have, the greater the chance that some of them will use your paid service, hence, you will benefit from them.

I think PX-Z meant that as a recommendation of what ViaBTC could do in the future. He didn't say that it it's already like that.

Try to switch Electrum servers. Maybe you will get lucky and find one with a more suitable purging fee rate. At the moment, nodes may be deleting (and not allowing) anything that pays less than 10-11 sat/vByte. So either pay more or try to find a different server.

They may need more time and update some of the software related to Foundry memepool to ensure that they receive serious fees compared to the traditional payment method. I don’t know, but if they contract with several mining pools, this may lead to making memepool.space a service that has a large number of visits, so it is better for the users’ experience to be better without problems or the need to contact the support team.

Also, if it's true that Mempool.space has partnered with Foundry as the pool that includes the transactions in their blocks, you will get a quicker confirmation since Foundry has more hash power and finds more blocks than ViaBTC.

If this is true, then you're right, but it's also worth noting that ViaBTC claims their paid service extends beyond their mining pool:

• Paid Service
  ViaBTC cooperates with multiple mainstream mining pools so that your transaction will be proposed and prioritized for quicker confirmation when any of our partner mining pool produces a block.

There are no restrictions for creating an account, but you can't use it for anything at the moment... Having said that, their "GitHub repository" appears to only have a single open issue about their accelerator, so perhaps it wouldn't take long before it's fully launched.

Yes, that's correct. The free service is for their own mining pool but ViaBTC's paid accelerator can include your transactions in partner blocks as well. Since several people have mentioned that the upcoming service of Mempool.space will be cheaper than ViaBTC's paid plan, I expect that Mempool.space will take a great chunk out of the pie for users looking to spend additional coins to accelerate their unconfirmed transactions.

[Synchronice]

I have noticed that too the new feature and it's definitely 5 times cheaper compared to viabtc but it's not cheaper though.

I just checked the acceleration fee for a random transaction and this is the estimated fee



So just make yourself that you are using a wallet that supports RBF and CPFP then you won't end up paying $50 or $500 more than what it used to be.

Acceleration fee is very individual, depends on the transaction fees that are recommended by mempool.space at given time and depends on transaction size. So, everyone will experience individually calculated fees.

Neither RBF nor CPFP are magically cures, they will only allow you some movement buy not always, and if we look right now what's happening, most of those tractions stuck that need help around are not made by users but by them claiming their coins from a service, and good luck doing something with those.

If you are not willing to pay, RBF and CPFP are not cures but if you are willing to pay, then, they are. To be fair, as you said, problem are transactions made by 3rd parties that send transaction with low fee and either don't support RBF or are not willing to do anything to increase transaction fee via RBF. So, these companies/services will feed transaction accelerators like mempool.space but things will probably change after Full-RBF.

Either they lower the accepted free txs every hour, say 50-80 only, have a cap for free txs in a block, or they stop their free acceleration service.

They've had this service for years, but tightened the rules a bit. I guess it's a "trial" for their paid accelerator service.

I guess so, i'm just concerned of how they performed on mining a block — on how frequent they get the mining reward, or it just other mining pool like faundry has more hashing power than other miners like viabtc. Well, to be honest i'm just concerned their free accelerators because it take so much time before it got a confirmation like i experienced before lol.

But it is free, so i would not complain too much .

If you pass all of their restrictions for their free accelerating service, waiting should not be a problem. ViaBTC has ~ 12% of the total hashrate in the network, which is smaller than what Foundry Pool has, which is ~ 25% of the total hashrate, so on average they would surely mine more blocks than ViaBTC.

I experienced this one when i accelerate my transaction on monday it really take how many hours before my transaction got a confirmation. Checking the last few blocks, it looks like Viabtc doesnt get one, a 1:10 ratio is not even possible, its usually the Foundry, Antpool, and others.

Actually a 1:10 should be ok, so a block evey two hours.
Viabtc got
- 50 blocks in th last 3 days (that's 50 in 408)  ~12%
- 116 blocks in the last week, (116 in  992)  ~11%
- 20 last 24 hours, again 12% out of 156   

A block every two hours would be pretty doable, but with bad luck, there are gaps:
Yesterday: 12:47:30 > 19:14:18

Electrum don’t even let me broadcast my transaction telling me that i am a cheapfuck who needs to raise the damn fee because greedy fuck miners say so or else they ain’t broadcasting my shiet.

So what should miners do, let you get  confirmation cheaper than some other guy just like you who pays more?
As long as somebody is paying you more for the job, why would take the lower bid?
Should we make some social score on the chain and give guys how move only $50-$100 priority?
Should we make ratios, one tx per capita per day?

[PX-Z]

But it is free, so i would not complain too much .

Yes, indeed. But once their mining business become not profitable due to the free txs they accept with how many hours of not getting a block. They will end up limiting free txs or cap txs for every block they mine which end up, either longer confirmation for others txs Or they stop their free service.

This is a good insights and observation. Thank you.

BTW,  visualization of expected blocks in the relevant row shown  on  mempool.space allows you to get to a whole series of initially hidden filters that allow you to highlight various types of transactions, for instance, by   various sighash flags or those ones containing inscriptors (which are of concern to everyone, etc. (see all filters in the image below).



To make filters visible, click on the goggles icon located at the upper left corner of the visualized block.

Just happened to see this new service on mempool myself and of course, arrived here on the forum to see someone saw it almost 2 months ago. As others note, the price is actually really dependent on your tx and current fee rate.

Yesterday, I sent out an unusual (for me) tx (Segwit, lean, several outputs), costing just under 10000 sats at mempool's "high priority" fee rate. RBF-ing myself to bump up the rate to 10% more was only several thousand sats but Mempool's fee was 40k sats for that. So about 400% on top of the fee paid. It was as if, despite the tx already at what they considered to be a high priority fee, they insisted to bump it up much, much higher.

Take it as you will, I obviously would need to look at many more tx fee to make a good comparison. I just feel they don't really optimise.

I guess they just take the highest end of the spectrum and decide to use that as their basis for fee bumping to get the tx confirmed and not base it on the lowest fee possible to get the tx in the next block. That's lazy acceleration, and I understand that people want to gey their tx confirmed in a timely manner during the busy times, but it seems that I'll stick to Antpool's service if this is how high they put their fees to be.

[NotATether]

I hope they add LN payments for that, the whole thing is a bit messy for those accelerators,  if you can't send or receive money because you paid a low fee and now you need to pay a higher fee to get a payment though to get that previous one confirmed it turns to funny situations like this one:

Imagine you have some hosted wallet on an exchange, the dumb mofos send your withdrawal to your wallet with 10sat/b and now you need to accelerate it, you only have BTC there so you make another payment to mempool.space but again, the idiots send the tx with 10sat/b. So you need to accelerate the tx that should have paid for the acceleration 

It's really messed up - having the acceleration for the transaction held up in a queue.

The alternate solution in case they don't want to mess around with LN is to implement account credit. It has its own drawbacks, but at least you'll be able to top it up when fees are not crazy. Assuming you even remember to that is.

Strangely, I have not really seen this feature on Mempool.space at all during that time. Maybe it was on their development version. By the way - did you know that the dev version of Mempool.space where they test all their features is on mempool.ninja?

Yeah, the dynamic price is a bitch when it comes to this, of course it's designed to be a profit service but it  just covers to much the needs of the pool and too little of the client pockets.
The 50k sat per byte is the turnoff for small tx:
a ‎135 vB tx costs now 53 500 sat , $22.89
a ‎14.74 kvB costs now 450 000 sat, $321.33.
But still, way cheaper than the alternatives, Viabtc  is asking for 4x!
