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.

Empty Bitcoin blocks occur when miners find a block using an empty template. Many pools send empty templates to miners because they’re faster to distribute, helping miners start work slightly sooner.
10.6% of all Bitcoin blocks to date were empty, the majority of which were in the early days when there were very few transactions.
Over time this rate has dropped significantly, and now ranges from 0.15% to 0.5% at the network level https://image.nostr.build/40d41a07db11de81f8c7f02c40768dc1d90d13822db915cff84b68424193f4c7.jpg

Default core policy is to treat each Sigop as though it has a 20 byte size. These transactions with many sigops are therefore treated as though they have a lower fee rate.

2024-01-05 22:46:04

- reply

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.

There are 25 different categories to explore, or mix-and-match to narrow down your focus even further.

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.

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:

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:

We’ve made mempool blocks scrollable (most useful on mobile)

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

We’re getting closer to our v2.5 release every day, but it’s complicated because of the new optional lightning node functionality. We should have updated Docker images published and an upgrade for Umbrel users within the next Two Weeks(tm), otherwise if you’re reckless feel free to upgrade your local instance to our master branch now 🤙

2022-12-26 13:28:55

It’s important to run your own @mempool node for security, privacy, and freedom: if mempool.space goes down you won't be affected if you run your own instance. We support one-click installation on Umbrel, Raspiblitz, Start9, and more https://bitcointv.com/w/gfCk3QqmtJrULZNwc2fRuU
