Approximately 60% of bitcoin blocks are merge mining other chains (since the last halving).
That's down from a peak of 96% in April 2020.
For our latest @npub1m7q…m4gz report, @npub18h0…ws8m analysed which merge mining schemes are in use, and which miners are using them.
Looking at recent data we see different miner / pool groups.
Group 1. No Merge Mining
Foundry, MARA, SBI Crypto
Group 2. AuxPow & “Chain A”
ViaBTC, F2Pool & Luxor
Group 3. Distinct switching pattern
Binance Pool, BTCcom, Poolin, Braiins, ULTIMUS
Group 4. Other
Antpool, SECPOOL
Taking a longer view looking back to the genesis block we see that adoption of schemes has fluctuated wildly over time!

good looks, did make that change but don't remember it causing high resource usage...just wanted to get rid of the log messages 😁

raspibolt guide looks old. just tested v3.0 with fulcrum according to our documentation for a fully manual install and it's working fine so far.
https://github.com/mempool/mempool/tree/master/backend
https://github.com/mempool/mempool/tree/master/frontend
recommend cross-referencing with our docs to see if you missed anything.
will run and observe for a day or so.

what does your setup look like? docker for mempool? have you tried running mempool with just bitcoind (i.e. without fulcrum)?

how are you running mempool? are you using umbrel, or something else?

How does Mempool Accelerator™ work?
We send your acceleration request to all of our mining pool partners, who prioritize your transaction based on your new accelerated fee rate.
To improve transparency all active and completed accelerations are publicly visible on the Mempool Accelerator™ dashboard and via our APIs.
Watch active accelerations appear in the next projected block live as they’re made.

The linked transactions have a large number of sigops (241).
Default bitcoin core transaction selection treats sigop's as though they have a larger size than they do. This means that these transactions are treated as though they have a significantly lower fee rate (half in this case)

Introducing Mempool Goggles!
Have you ever wished you had x-ray specs to see exactly what's inside the mempool?
No, me neither, but we built you a pair anyway.

Click on the Mempool Goggles icon at the top left of the mempool block visualization to reveal the new filter menu.
There are 25 different categories to explore, or mix-and-match to narrow down your focus even further.

Want to see how much of the mempool is occupied by monkey jpegs? Try the "Inscription" filter.
Curious how many transactions use both RBF and CPFP to bump fees? Hit the "Replacement" and "Pays for parent" filters.

There is no API call for the number of mempol blocks, but this can be estimated by dividing the sum of the vBytes in the mempool by 1,000,000
The number of unconfirmed transactions can be called directly.
Here is a python example:
import json
import requests
import math
# Approximate number of blocks in mempool.space's mempool
total_blockVSize = sum(item['blockVSize'] for item in requests.get('https://mempool.space/api/v1/fees/mempool-blocks').json())
block_count_estimate = math.ceil(total_blockVSize/1000000)
print("Unconfirmed block count: ", block_count_estimate)
# Get transaction count
transaction_count = requests.get("https://mempool.space/api/mempool").json()['count']
print("Transaction count:", transaction_count)

Recent median fee rates are below 20 sat/vB despite the presence of over 557,000 unconfirmed transactions in our mempool.

thanks for asking...that was a bit unclear. romanz/electrs and fulcrum will still be supported. we meant that blockstream/esplora won't be supported anymore, which only affects big production deployments.

We’re working on major improvements to The Mempool Open Source Project as part of our upcoming v3.0 release.
Here are some of them, which are already live on mempool.space
---
1/
We’ve re-implemented our block template algorithm in Rust for improved accuracy and performance.
Before:
https://cdn.nostr.build/i/356310639d551a28dd5cc095998f0b7908a8ac51a6def2034ff0a010da910942.jpg

---
2/
We’ve begun visualizing both `mempoolfullrbf=0` and `mempoolfullrbf=1` transactions together
on our RBF timeline.
https://cdn.nostr.build/i/8ec67f9356538adf21f33b4c6e13111fe783fdf8cab3380d68aa8a04caf60e36.jpg
---
3/
We’ve forked blockstream/electrs to mempool/electrs and made many fixes and improvements.
(it's a breaking change -- mempool/mempool 3.x will require mempool/electrs 3.x)
https://github.com/mempool/electrs
---
4/
We’ve started integrating Mempool Accelerator™
https://cdn.nostr.build/i/97d168edb1b22b3bd5a7e2a269c32650e892aa030030862f9ef2bc317675ebef.jpg
---
5/
We now display and index P2PK outputs using their public keys.
Here's the first Bitcoin transaction from Satoshi to Hal Finney:

---
6/
We’ve made mempool blocks scrollable (most useful on mobile)
https://cdn.nostr.build/i/e3495a165600dcc5230bc1d46ecb67b50a90c0e5af4d792dfd34eae16497ca6c.gif

7/
We’ve imported historical mempool data from 2017 and 2018, thanks to a contribution from Jochen Hoenicke (https://jochen-hoenicke.de/queue/#BTC,all,weight).
https://cdn.nostr.build/i/bb25299d8f6e07cea8695572c92a48d26ba09186fcb787f37d2e66a832da9542.jpg
