At the very least, they've updated it to include the "weight" value which can be divided by 4 to get the vSize.
It shows whether there's witness data or none.

It can never happen because Bitcoin Core doesn't have a USD value displayed in the "Overview" tab.
OP is most likely expecting that his BTC balance will fluctuate based from the market price of Bitcoin.

Based from the OP's context, it's his hardware wallet's seed phrase.
Even though he didn't mentioned it, the information "derivation path" and "Account 0" (from "Detect Existing Accounts") indicated that he have imported a BIP39 seed phrase.

Changing it into the standard TapRoot derivation path will only generate the associated prvKeys/pubKeys of your TapRoot addresses and derive the selected script type,
not the actual TapRoot addresses themselves since Electrum currently doesn't support it.
For example, if you've selected "Legacy" then changed m/44h/0h/0h into m/86h/0h/0h, the addresses will still be legacy.

Your option is to use another client that supports taproot like Sparrow.

They can indeed reach even the maximum nonce value in a second.
But there's something called an "extra nonce" which can be anything in the block header that could be changed after the maximum nonce in reached.

Each miner has their unique or simply a widely-used method of getting extra nonce,
For example, some pools are changing a value in their coinbase transaction's OP_Return output which will produce a different "merkle root hash".
With that they can restart the nonce since there's something's changed in the block header.

What is "Bitcoin Core 2" application?
Are you using "Bitcoin Core" or another client with a suspicious name? Because Bitcoin Core doesn't have an official "2" variant.

As for your bitcoin balances in the overview, it wont automatically get interest/deductions based from the market price.
Even in other clients, your (for example) 1.00BTC wont become 1.01BTC just because Bitcoin's price rose, it doesn't work that way.

Now that's a useful error message.
The error "Script failed an OP_EQUALVERIFY operation" means that the server failed to verify your input(s)' script.
In other words, the signature is invalid.

I really wonder what kind of input you're trying to spend.

Useful info for others:

• Since the first transaction has a very high txn size, his address must be one of those old high-value addresses that received lots of dust transactions.
• His first screenshot slightly shows that he's sending three-digit bitcoin amount (or more) which supports the idea above.

It's not the amount but the size of the transaction, you can use coin control to select the highest value UTXO in order to send a small transaction with the highest possible value.
It's also recommended to leave the dust coins untouched.

Enable the 'Coins' tab in "View->Show Coins", Go to that tab and sort it by amount by clicking "Amount"
right-click on the coin of your choice and then select "Add to coin control".
When you use send, that input will be selected alone.
(you can multi-select via CTRL or SHIFT to select more than one input)

Yes for standard Electrum seed, make_seed command takes seed type option like "standard": github.com/spesmilo/electrum/blob/master/electrum/commands.py#L338
But you can't create P2SH-SegWit seed with it since it's never been generated in Electrum natively.

If you want a SegWit "3" wallet, import a BIP39 seed you've generated elsewhere by ticking BIP39 seed in the option and select p2wpkh-p2sh option when prompted to select the script type.
Forcing your Electrum seed to be imported as BIP39 will work but the process isn't standard so it's not recommended.

That will also work.
There's no issue in importing a private key and deriving a different address type from it, it can spend from it without issue.
But creating a backup of this will be more troublesome than backing-up a seed phrase.

The issue is importing an uncompressed WIF private key as SegWit/Nested-SegWit but Electrum wont allow it.

Did you mean, custom words in your random seed phrase, Yes?
(what's with the roll eyes tho?)

This isn't much of a guide but it's basically the only step that you need to do:

---

The "english.txt" file or other languages are in the source (github.com/spesmilo/electrum): "electrum\electrum\wordlist"
In your own copy, delete every word in the language of your selection (your PC's language) and type your own list.
Compile it or run from source.

Electrum will use that list when creating a new seed phrase during wallet creation.

The "Use change address" setting is now in the 'New Transaction' window.
To get there: after clicking "Pay...", click the settings icon "" (upper-right) and a drop-down menu containing the said setting will show.

But this thread has a different topic; next time and/or for follow-ups, please consider opening a new topic.

I don't use Telegram and most users here prefer it in public so it can be used for reference like solving related issues.

Have you checked your logs if there are error-related entries?

Or if you want fast results, share your transaction here so we can check what's wrong with it.
But that includes privacy issue, share only if you don't mind sharing info like sender, recipient and amounts.
You can get the unsigned RAW transaction from (after clicking "Pay..."): "Preview->Share->Copy to clipboard"
or just "Share->Copy to Clipboard" if you're in Advanced preview already.

I only got a glimpse of a small portion on the amount from your screenshot but it looks like you're sending A LOT of bitcoins.
Perhaps there's "something" in the inputs that you're trying to spend that's causing errors that aren't in the list of common errors in Electrum.

It'll be hard to find a solution to the issue because of the "Unknown Error", the issue isn't specified.
But AFAIK, it's the replacement error message if the server is trying to send you a malicious phishing message.
If you're using an old version, update it ASAP.

If not, see if you can find the cause by enabling logging by ticking "Tools->Preferences->Misc->Write logs to file", restart Electrum.
Reproduce the error in the next session while Electrum is logging, then check the recent "electrum_log" in "logs" folder inside Electrum's data directory (location).
Disable logging later.

It's not similar.
That's only the generic error message that always appear when there's an issue during send, the actual issue in the one below it.
In OP's case, "Unknown Error"; that link's issue was "insufficient fee".

No, it doesn't; just like Vanitygen.

You read it right but it's not the way you think it is.
If you're aiming to use the private key of a vanity address and convert it into a seed phrase in hope to restore the same vanity address, it wont work.

That's because the addresses derived from a seed phrase aren't based from the initial entropy but from the mnemonic itself (the 24 words) which is used to derive a "seed".
Not to mention that the vanity address is derived from its private key in a specific way, not the same way as deriving private key and addresses from a seed.

Is you Sparrow wallet a "Hot Wallet" which is created by generating/importing a BIP39 seed or others?
Because if it's an imported Electrum wallet keystore, it wont work on that wallet.

For testing purposes, restart Sparrow in Testnet mode (Tools->Restart in Testnet).
Create a new wallet wallet and select "Software Wallet->Mnemonic Words (BIP39)".
Then fund that wallet using testnet faucets.

Have you tried this link: https://sparrowwallet.com/docs/mixing-whirlpool.html#preparing-the-wallet
That has the correct steps on how to use Whirlpool in Sparrow.

Plus I don't think that it's the Analytic's fault why it wont proceed to Whirlpool.
Basically, you start in "UTXOs" tab to 'premix', not "Send".

Use VanitySeach for faster speed and for possible GPU support (depending on your GPU) instead.
With that tool, use -o arg to specify an "output.txt" file where the private keys will be saved.

Bitcointalk Thread link: https://bitcointalk.org/index.php?topic=5112311.0

It's more of a "help" to the network than self-advantage.
Since with listen=1, other nodes can initiate connection to your node which is usually those who need to download the blockchain.

The disadvantage is you'll likely use more internet bandwidth with it stayed enabled.
That's if your router is already setup accordingly; otherwise, your node still can not allow inbound connections even with listen=1.

Is Sparrow running on a separate machine?
If so, there's nothing to configure there but to set your EPS's correct .onion address and port since it'll automatically start its own integrated Tor client when connecting to your server.
In that case, if it's set correctly, look for Tor issues in your machine where EPS is installed.

I don't get what you mean but, in simple words: the 24words that you've created with that tool wont restore the same address it generated if imported to any wallet.

If you use the tool in a secure environment like in an Air-Gap machine, then using the WIF private key it generated is secure enough.
But based from the OP and title, it's not the tool that you're looking for since you can't use the mnemonic and BIP39 passphrase.

Since the channel has just opened, I assume that it doesn't have enough "inbound liquidity".

If so, follow this guide for ways to be able to receive bitcoins through your channel,
