[Mar 2026]Mempool empty, Consolidate your small inputs @0.11 sat/vbyte

[LoyceV]

By mistake I send a transaction for 1 sat v/b in coinomi ( i wanted to send 1.1 but by mistake I sent 1 lol).
Now it is stuck! I will just wait a few days until it drops (I hope!!)

I don't know about Coinomi, but when I did this in Mycelium (years ago), it kept broadcasting so it never dropped out of mempool.

Fees in the second next block are now at 1.02 sat/vbyte.

My idea was to drop it, so I could just make a new one with higher fee.

However, my transaction of 1 sat vb was confirmed just an hour ago! Amazing

I will make some good consolidations now!

That's been a while! When I check mempool.space, I see 1.02 and even 1.01 in expected 2 blocks into the future. Could it be some miners don't look 2 decimals deep when deciding which transactions to include?

There were even half empty blocks now:

https://mempool.space/block/000000000000000000028ba6f977265daa7f1e7e2c65e7a38289ffe738e5b9bf

I think some miners are just a bit random and it is hard to understand how they choose transactions sometimes.

Looks like software used by F2Pool is still sloppy. It reminds me of their past mistake which cost them money,
Invalid F2Pool blocks 783426 and 784121 (April 2023)
P2TR spending transactions missing from F2Pool and AntPool blocks (2021)
July 2015 forks and SPV mining: Why did F2Pool and AntPool mine an unverfied chain for so long?

[LoyceV]

Currently, transactions paying 1.0 sat/vbyte are getting included. There's still a pile waiting, so if you create one now it may still take a while, but this is very promising.
I also noticed the data spam is much less. For many months, it filled 80-95% of the blocks. Now, it's around 20%. But those same spammer (I still assume it's the work of one person) is consolidating all his spam dust inputs (like this one). I wouldn't be surprised if the data spam continues when he's done consolidating.

[LoyceV]

For the first time in almost 2 years, Mempool was empty last night:

If you have anything left to consolidate, now's the time! If you're not in a rush, 1.0 sat/vbyte (the absolute minimum to be accepted by other nodes) should be fine.

Empty mempool but Bitcoin at ~$100K.
Does everyone buy Bitcoin through ETFs only?
Also doesn't anyone use Bitcoin in real (on-chain) transactions?

ETFs or keeping money on exchanges.
It's been like that since the data spam started. Even now, most of the block space is filled with data spam:

As much as I like to see Bitcoin as electronic cash, it's turning more and more into an investment that only a few people use as electronic cash.

Indeed, exactly my thought, unfortunately.
I don't think it's only the fees that make people not use it, but also the ~10 minutes for 1 confirmation. The 10 minutes are perfect for the network's security and longevity but for everyday transactions they can be painful.

I can think of a few more reasons:

• high withdrawal fees from (some) exchanges
• (some) exchanges promote their own made-up counterfeit centralized tokens as if it's Bitcoin
• most "Bitcoin users" don't even install a wallet

I can only conclude most people aren't ready for self-custody.

[apogio]

I can only conclude most people aren't ready for self-custody.

That's mainly because most people (99%) hear "something that can 10x in value, so put your money there and wait to have more FIAT later".
Instead, I am hearing "a revolutionary system that can work as a proper currency, where you can actually hold all your money without trusting anyone".

You hit your head years ago and have just woken up now? Forgive the irony, but I've seen it that way for years now.

• most "Bitcoin users" don't even install a wallet

I rather think that what should be explained is the opposite: why they should use it as cash. I don't see the fact that was invented that way as a sufficient reason if it is much more useful for storing value and transferring it in large quantities nowadays. When people are willingly abandoning cash and paying with their mobile or watch, regardless of privacy, there is no way they are going to use the blockchain.

If you convince someone to use it and make a payment by waiting the 10 minutes or so that apogio mentioned, they may look silly if suddenly there is a huge dump in the mempool and they have to wait an hour or more, or they have to learn how to rbf to get the transaction confirmed to pay for the coffee. Also when paying with mobile phones there are no fees to pay, while with bitcoin not only are there fees, but they are quite variable, as we have seen in this thread. Not to mention the problems of scalability, which LN tries to solve, but which is also more complicated than paying with your mobile phone.

In addition to the fiscal problem. If I pay by mobile phone, I forget. If I pay with bitcoin I have to worry about collecting data to declare each and every one of the payments I have made in the previous tax year to present them in my income tax return.

As things stand in 2025, or at least as I see it, what needs to be explained is why the masses who are adopting bitcoin should use it for day-to-day payments and not as a store of value and large payments.

There's not enough block space for everyday transactions for a lot of people, so that's not really a problem. I had high hopes for LN years ago, but it never took off and I currently don't even have a LN-wallet installed anymore.

We're one block away from an empty mempool! EMPTY. I mean, WOW And I'm all out of inputs to consolidate.

I do, but these days i usually do it for services with yearly (or longer duration) payment. Meanwhile, few service and merchant report higher usage of XMR (compared with BTC) despite XMR price doesn't change much in last few years.

It didn't last long.



Although it's still good time to consolidate, since there's no indication default minrelayfee will be reduced anytime soon.

[LoyceV]

That's another data spammer creating 1.01 sat/vbyte dust inputs. Imagine paying $63 to turn your Bitcoin into dust, and doing it often enough to fill many blocks!

Miners have no reason to reduce it, and other nodes don't really have a say in it.

And depending on the spam, it also increase total UTXO. Although since the spammer use 1.01 sat/vB, now i feel weird that fair amount of unconfirmed TX use 2 sat/vB or higher. Mempool visualization probably should start give more detailed visualization (e.g. 1.0 - 1.5, 1.5 - 2.0) while wallet give only slighter fee rate recommendation (e.g. 1.1 sat/vB rather than 2 sat/vB).

That's true. Although it could change if Bitcoin Core and other full node software were to reduce default minrelayfee value.

Why is there a minimum in the first place? After 2 years of data spam paying hundreds of millions of dollars to spam, "spam" can't be the reason for a minimum of 1 sat/vbyte anymore.

[BlackHatCoiner]

So that you can have the freedom to determine yourself what's considered unacceptable to relay.

After 2 years of data spam paying hundreds of millions of dollars to spam, "spam" can't be the reason for a minimum of 1 sat/vbyte anymore.

The minimum relay fee aims to reduce the spam on your mempool, not on the network. Even if default minimum relay fee was 10 sat/vb, those people could still broadcast them to mining pools directly.

You don't want people bloat either blockchain or mempool with 0 or near 0 TX fee. Although FWIW, the default value was last changed in early 2014[1].
