BTC's Luke Dashjr: '24 Bitcoin Core Update Will Disrupt Ordinals, BRC-20
get some theory of mind. you are a person who is willing to pay onchain fees to use your trezor or open a channel. there are people in the world who are not willing to pay these fees and they probably outnumber you. and the plan has been spelled out in plain english a million times. the fees are supposed to go up by design. this means that most people will not self-custody, whether it is legal or not, and even if they would like to.
- bitcoin transaction fee too high in trust wallet
- If the answer to high onchain fees is using layer 2, how do you get your layer 1 btc on layer 2 without encountering the same high fees?

Fee question
https://mempool.space is usually pretty accurate
You can view the transactions that are currently in the mempool and see what an adequate transaction fee for a very slow, slow, medium, and fast bitcoin transaction is on this website: https://mempool.space/

Mempool.space differences when compared with my node
by default, the size of the mempool is 300mb. mempool.space's is 1GB I think. That would dictate what transactions you're seeing, and therefore the fee ranges there's a whole host of settings beyond size too, so who knows what their set up is exactly.
I am comparing the fee spans between mempool.space and my server and the values are slighly different even for commited blocks. For example, mempool.space shows 132 - 1,773 sat/vB for block 820047 whereas my server shows 140 - 4,805 sat/vB. Why the differences?
I am using their software (mempool.space's) and I also have Fulcrum server installed (appears to be relevant) but I haven't updated it since it was installed so maybe this is due to different versions of the software.
I mean, we'd have to know how slightly is slightly. it could just come down how the user's node represents the data versus how mempool.space does.

Generating and Working With ScriptPubKeys in Bitcoin Transactions
As mentioned previously, ScriptPubKeys are scripts that embody the locking conditions of bitcoins in a Bitcoin transaction. They are a crucial element of a Bitcoin transaction that specifies the requirements that must be met before an unspent transaction output (UTXO) is used. The ScriptPubKey, combined with the Amount, creates an output of a Bitcoin transaction. Like every other script, ScriptPubKeys are made up of operators and data. During the encoding of a transaction, both data and the operands are represented in hexadecimal format. You can find the hex representation for all operands used in Bitcoin Scripts here.

Bitcoin Core 26.0
Here are the release notes: https://github.com/bitcoin/bitcoin/blob/26.x/doc/release-not...
It's blatantly false that "Bitcoin Core was purchased by Blockstream".
It's absolutely not the case. It's more like a conspiracy theory that keeps getting pushed into Bitcoin-related threads at Hacker news (maybe to tilt future analysis?)
If we take a look at the past month of commits from https://github.com/bitcoin/bitcoin/pulse/monthly, the top ten authors are:

ZeroMQ – Relicense from LGPL3 and exceptions to MPL 2.0
Fun ZeroMQ fact: bitcoind has used zeromq since 2015. This is used by client software including lightning node daemons to get notification of incoming transactions and blocks in a highly reliable and rapid way.
