Looking for peer nodes for sub 1 sat/vbyte transactions

Hey everyone, I’m trying to figure out how to find peer nodes that will accept sub 1 sat/vbyte transactions and send them over to Antpool specifically. What I really want is for certain transactions to get picked up by the Antpool Tx accelerator and NOT by any of those NON Antpool partner pools. I’m looking to skip the Antpool acceleration fee that comes from having the transaction mined elsewhere. I’ve already got a version of bitcoind that can handle these transactions, but even though my node is up and running on an AWS HK instance, I can’t seem to find any Chinese peer nodes to relay from my local mempool. Can anyone offer some tips or advice on how to reach my goal? Appreciate any help!

I don't get your point? Isn't that Antpool TX accelerator asking for payment if you submitted your TXID? Any TX accelerator is expensive, even in ViaBTC, and what's the point of submitting your transaction with 1 sat/vbyte if the current network right now is not congested and the recommended fee is 1 sat/vbyte? Have you checked mempool.space about the fees nowadays? Did I misunderstood? Or is your goal just that you want your transaction to be confirmed by Antpool?

he wants a fee below 1 sat. as sub 1 sat means under 1 sat btw I was not aware that miners will take a fee like 0.5 sats a byte

Correct I want to be able to have say 0.98 sat/vbyte tx seen by antpool tx accelerator. Global mempool would not see it but some are able to get it to be seen by antpool accelerator. I have a specific purpose for doing this as I know it likely doesn't make sense without knowing why. I figured this forum would be a good place to find someone that can help me out.

I don't think any mining pool publicly advertises its node's IP address because it could become a vulnerability and attacked. Also in the Bitcoin's peer to peer network when majority of nodes don't accept something (eg. <1 sat/vb rates) it won't propagate which means even if you found nodes that accept such transactions, it is still highly unlikely for it to propagate enough to reach a specific node like Antpool's node. The only viable solution for what you seek is if the pool's website accepts the rawtx itself instead of the txid only. For example https://www.f2pool.com/user/tx-acc does also accept the rawtx even though it says enter txid (not sure if they accept the tx that is not in their mempool though).

This is only possible if Antpool set their Bitcoin nodes to relay transactions with lower than 1sat/vB. If you're basing this off to their own transactions with zero transaction fee: don't; because that's unrelated to their minimum relay fee policy. Miners can freely add non-standard transactions to their blocks using their proprietary software without changing the standard rules of their nodes. Unfortunately, this will likely turn into an X/Y Problem.

he may be able to do it if he runs a ton of nodes in a local area say a county like Sussex, Delaware, USA (small place with under a few hundred thousand homes) So he would need to set up a decent amount of nodes in that area. But he would need to know how the county is routed for the Internet  and he would need to know a lot of nodes. which could force info into the choice nodes But frankly I don't think it would be easy to do. Costly complex work. https://bitnodes.io/#google_vignette 21000 nodes world wide not sure how many he would need to do it, but at least a few hundred along with a pool. You could get a pool to do it if you run a solo pool with about 1eh which would mean 58,000 a day rental from nicehash I think it could be done for around 1 million

I don't think there's any mining pool including transactions paying less than 1 sat/vbyte as fee into the blockchain normally. Such transactions are considered non-standard and would be rejected by the nodes. For a transaction paying less than 1 sat/vbyte as fee to get confirmed, you have to get in touch with mining pools and ask them to do it for you.

If you don't mind only achieving second goal (other node doesn't see your TX while it's unconfirmed), use MARA slipstream service. Even if he somehow managed to connect to one of nodes owned by mining pool, it's still pointless if those nodes aren't configured to accept TX with fee rate below than 1 sat/vB.

I'm not sure if you can directly broadcast the transaction to the accelerator but if you can, that would be a good place to start. There is no guarantee that there are other HK nodes that are connected to Antpool as a peer. This kind of transaction *should* be mined directly IMO. Perhaps contact the miners directly and ask them to relay this transaction for a fee that will be paid in advance, and with a different transaction.

If he ran his own solo pool and rented an eh from nicehash he should hit a block in 7 days or 58,000 x 7 = say 420,000 dollars. Bad luck could be a lot more than 7 days time and way more than 420,000 dollars. His node for the solo pool would take the transaction and he could have general nodes near his pool node set to accept it. But it would cost money. To do this. One could argue a pool may allow it for a really large fee say 50,000 usd but he still needs supporting nodes.

An EH that's a huge hashrate and too expensive just for the sake of including this transaction with below 1 sat/vbyte? I don't think it's worth it unless OP is willing to do this for learning purposes, and I think if he luckily mines a block successfully, then he also gets rewarded with 3.125 BTC but the chances is pretty low due to high difficulty. @OP Why not tell us more about the "specific purpose for doing this"? Because having a full node and hosting a pool and renting hashtags isn't cheap.

It's not very likely that you find peers that accept transactions with less than 1 sat/vB as fee rate. This threshold is the default for the majority of peer's mempool to accept a transaction for relay. Why do you need Chinese peer nodes specifically? I'm also interested in the specific use case of the OP. It sounds a bit weird and convoluted, but he's not specific on his own use case. @bitdigger2025 please explain your use case if possible. Today, notably between block heights 898284 and 898308 but also on other occasions, most blocks were only partially full, i.e. it should've been no problem to get transactions mined that pay only a fee rate of exactly 1 sat/vB. Why the hassle with sub 1sat/vB and sticking to Antpool for whatever reasons? Almost no other node will be able to relay such sub 1 sat/vB transactions.

You can not broadcast your transaction directly to Antpool and hide it from other mining pools. There are many Bitcoin nodes and mempools so if Antpool does not confirm your transaction, other pools might do it. Depends on their mining pool hashrate power and frequency of finding Bitcoin blocks as well as randomness, your transaction can be confirmed almost immediately by Antpool but can be confirmed by other pools too. There are many tx accelerators but they are mostly paid services. Fee rates under 1 sat/byte were available years ago when Bitcoin was far less adopted than now. Nowadays, such fee rates are not applicable except if you are not a Bitcoin mining pool owner and can broadcast your transaction to your mining pool's found Bitcoin block.

🤔 If all that work is what's actually needed to make a transaction for 0.5 sat/vB, then OP, just pay the 1 sat/vB. We can confidently say that it's going to be a lot easier and CHEAPER for you. But shower thought, when Bitcoin surges to a seven digit valuation or more, then sub 1 sat/vB per transaction should be allowed by the network, no?

It can be. Latest topic about it: https://bitcointalk.org/index.php?topic=5528323 But, as I said before, it is double-edged sword: as long as minimal fee rate is 1 sat/vB, then miners will always get at least 0.01 BTC from fees, as long as blocks are full. If you lower that value below 1 sat/vB, then you will also lower potential miner rewards in future blocks. And then, when they run out of basic block reward, it will be very important, to have a good fee policy, because then they will get everything only from fees. Well, it is just another proof, that some de-facto-standard rules works fine in practice. Not everything is limited through consensus rules. There are many standardness rules, and good practices, which are used by many nodes by default, and as you can see, many such rules are enforced properly. Because from consensus rules alone, all free transactions are valid. But: if we would have no minimal fees, then we would see much more spam, than we can see today.

👍 Although, miners' monthly costs are denominated in United States Dollars/fiat, and if Bitcoin is priced with a seven digit valuation, it would be expensive to transact using 1 sat/vB during every transaction. It would truly be more expensive of those dick pics and fart sound lovers start using the blockchain again. I was merely replying to phillipma1957's suggestion, but you're right. 👍

That is also posted in the Bitcoin Mailing List. (there are more interesting replies there regarding its risk) Link: groups.google.com/g/bitcoindev/c/3CRqKviJY_M/m/w89e1gQgBQAJ Even now, it may work even if there are only select number of nodes that have lower minimum, but you'll have to be either lucky or specifically connect to them for the transaction to propagate to those nodes. And at least one participating mining pool/solo miner is required since the successful relay would be useless without a miner who's willing to mine it. (which is the biggest hurdle)

yeah renting from nice hash is 58,000 usd an eh and the network is around 900 eh so 144/900 chance per day if you spend 58,000 in rentals. or maybe if you offer   0.15 btc directly to a pool they may include it. along with having to load up a ton of nodes to accept it. I still do not understand the why of it. At one Time 0 sats worked and I kind of remember 0.5 sats could work back around 2013 or so So it is old ground being covered.

OK, but let's say Bitcoin did surge to $1,000,000 per coin. It would be too expensive for many users, especially for plebs like me, to pay for a transaction costing a 1 sat/vB fee to send small amount of Bitcoin to a casino. What would happen if the majority of users started to use < 1 sat/vB fees per transaction. That would force the miners to actually start searching for those transactions instead of mining empty blocks, no?
