A few months ago, I wasn't sure whether I should run a Knots node or not. But in recent weeks, it has become increasingly clear to me that BIP-110 is a MUST.

Since Bitcoin Core v30 the "datacarriersize is increased to 100,000 by default, which effectively uncaps the limit (as the maximum transaction size limit will be hit first)" https://bitcoincore.org/en/releases/30.0/
The default value in the previous Bitcoin Core version was 83 bytes, that is enough for monetary use cases, e.g. Peg-In transactions to the Liquid sidechain require an OP-RETRUN size of 36 bytes.

I've been following every minute, but you should take a closer look at bip110.org/.
You complain that you're not happy with what Core has done, but you haven't proposed a solution to fix the problem. If you have a better answer than BIP-110, I'll support you immediately.

Bitcoin is owned by humanity, the protocol developers are stewards, and need consensus from users to change it materially. bitcoin is about money, spam has no place in the timechain. what defaults the bitcoin core project puts in the reference client matter in this.
in may there were 88mil JPEGs in the chain, now 4 months later, there are 105mil JPEGS, a 20% increase. in may 7000btc fees had been paid, at $100k btc that's $700m or an average of $8 per JPEG. they are primarily in taproot inscriptions. (@BitMEXResearch data)
protocol rules are enforced by economic nodes, miners are just service providers; miners cannot change protocol rules. (everyone learned that counter-intuitive fact during the block-size wars). proof of work, hashrate and bitcoin price come from the real world. there are signals
the block-size war was won by the market, users set the price in the market. (the protocol can measure consensus valid hashrate which reacts to price. users said NO via the economic force of the market. miners followed, as they are just service providers)
to prevail, we have to make economic sense (or we work against our own objectives), and laser focus on outcome: where is the spam coming from? the JPEG industry JPEG sellers & buyers, VCs funding it and miners collecting $250m/year (very rough estimate) from the fees.
that's about 1.5% of the fee market. note fees are not simple: blocks are not always full, the spam displaced other transaction fees, lets pick a crude estimate 1% of excess fees from spam vs transactions. if fees are persistently higher miners invest in buying more ASICs, and
push the hashrate and input costs up, so the incremental net revenue would be less say 0.5%. if a given miner makes 20% profit, then maybe the spam industry is 0.1% of their profit once the hashrate settles higher. not really something they should focus on, as it also is bad
for bitcoin - prices new users out of owning a UTXO, displaces economic activity that is part of bitcoin's value proposition. yes JPEG spam is economic activity but it's extremely wasteful, they can store JPEGs in other places which are optimized for that like imgur, ipfs etc.
so you would think that miners and pools actually would not want to take too much negative PR (public miners anyway where that can impact their share price). for a 0.1% bump in profit, you could easily lose that to soft-factors - miners switching pools, hurting btc price, hurting
bitcoin use cases, adoption etc. so it looks like it should not take too much of a nudge to add friction and get the miners to do less of it. some explaining, some outreach to miners to switch to pools that don't mine JPEGs. and maybe some actual economic lobbying by fee paying
users, to deprive pools processing spam of transaction fees. so far it seems hard to do without creating centralization risks of it's own, but as a sketch wallet sends minimum network fee and rest of dynamic fees to 1 of n multisig of pool addresses that reject JPEGs.
that could be enough to make pools not filtering JPEGs even short-term unprofitable vs filtering. the centralizing issues are: solo miners and small pools maybe not in the list, but NB there aren't many pools. and sv2 and datum can be larger without chosing blocks. i guess
that could be used to bypass the pool preference, or pools in sv2/datum are "trust the pool" model, the pool could reject pool shares with JPEGs (or anything else they wanted to block), which cuts both ways.

I have been wearing zero-drop shoes for three years. Start slowly and train your foot muscles and calves like you would your biceps. Pay attention to proper posture—that was my biggest obstacle. Your Achilles will thank you. Decades of wearing supportive shoes leads to weak feet. The beginning is difficult. But once you've learned to control your foot muscles individually after a while, it becomes really fun. Plan on at least a few months for this. It's worth it!

So we are on the same line with the power the node runners should have over their mempool. I will definitively use the filters and try to get only transactions into my mempool, with the usecase of Bitcoin as money. I do not want to host jpgs, runes or dumb messages in the OP_RETURN field on my hard drive.
Are BRC-20-Token responsible for the UTXO bloat? What started 04-2023? I do not think that the issue of spam filling up the blockchain is massively overblown. The UTXO count doubled from Q2/23 to Q2/24! A part of the node's RAM has to be used for this non-monetary use of the blockchain.

I'm in the camp where filters do work. And as a node runner I want to control what gets into my mempool. It is unacceptable that future versions of Bitcoin Core will restrict this option. Feel free to convince me, that it is a progress for Bitcoin as a monetary network, when the power of the node runners is reduced.

Ok, I understand.
I have all this stuff running in a VirtualBox Linux VM with Umbrel installed. The additional resources are peanuts for my server.
If you cannot use a local Bitcoin Explorer, you must be aware that a public Bitcoin Explorer will log your IP and your query data, e.g. transaction ID. This can then be linked to you via a query to your ISP. If you want/need to go this route, then a VPN would be helpful to obfuscate the last step.

Ok. that's clear, every node has its own mempool.
But what I meant was this: Do you have a local tool (see my screenshot of the URL http://btcnode.local:3006/ = http://192.168.178.62:3006/) installed to retrieve information about transactions or addresses, whereby this tool interacts only with your local Bitcoin node to get this information from your locally stored blockchain?

2. 📂 Locate & move your data directory (usually `~/.bitcoin` or `C:\Users\YourUsername\AppData\Roaming\Bitcoin`).
3. 💾 Install Bitcoin Knots from [their official website](https://bitcoinknots.org/).
4. 🛠️ Configure Bitcoin Knots to use your existing data:
- Create `bitcoin.conf` in Knots' data dir.
- Add `datadir=/path/to/your/moved/data`.
5. 🚀 Start Bitcoin Knots & let it verify your data.
6. ✅ Check sync status in the debug console.
