Version 4.5.2, macOS 12.7.3 Monterey

This is second time I found unpaid invoiced within Send area of Electrum. See screenshots. Small amounts but anyway I'm absolutely sure I did not create these invoices.
Who knows what's that?

since 4.4.1 version there is no Replace-by-fee checkbox in Electrum settings. Who knows how to disable rbf? Bitpay requires rbf to be disabled. What happens if I ignore this requirement?

Please take a look at this transaction
https://www.blockchain.com/btc/address/3DgYkeJR7QC6YEsYRawr3KoXvit7N6SWuf

The transaction from an address with confirmed coins and with quite sufficient Tx fee is not confirmed since afternoon till midnight!
What can be the reason of such delay?
I guess CPFP won't help as the parent was confirmed yesterday

Hopefully at the time you read this it will be confirmed already.

I have Electrum Version 3.3.8 on Mac

Some addresses have unconfirmed coins, I used "Freeze" option for those addresses, then I checked "Spend only confirmed coins" in Electrum properties.
Anyway, Electrum sends from addresses including frozen ones. It also can be seen in transaction preview under "Send" tab before the transaction is sent.
If I use "Spend from" the transaction will not be broadcasted and I receive an error something like "Server returned an error, try to select another server..."

Is this a bug? I saw on this forum that people use these features and everything seems to be fine.

What's wrong with my electrum or what I missed? Please help!!!
 

Who knows how to enquire electrumx to get balance of Segwit addresses - p2wsh or p2wpkh?

In case of legacy addresses - it is described here

So, how to build 'scripthash' from bech32 address to send this request?

Code:

blockchain.scripthash.get_balance(scripthash)

MAC OS El Capitan
Electrum 3.3.8

For some mysterious reason there are two processes of Electrum as shown in the screenshot

Is that normal?

Code:

$ ps aux | grep -i electrum
username   6953   0.9  1.0  2792496  43352   ??  S     1:28PM   0:15.79 /Applications/Electrum.app/Contents/MacOS/Electrum
username   6951   0.0  0.2  2531360   6876   ??  S     1:28PM   0:00.90 /Applications/Electrum.app/Contents/MacOS/Electrum

One of the processes is always "Not responding" and it is the parent of another one. If I kill either of them, then both processes will be terminated.

IMHO it was only one process in the past. Being little bit paranoid I installed Eset antivirus but it found no suspicious process (I did not scan the full disk as it takes ages and it heats the laptop like a pan)

Has anybody notices that as well?

The description states:

Code:

A script hash is the hash of the binary bytes of the locking script (ScriptPubKey), expressed as a hexadecimal string. The hash function to use is given by the ?hash_function? member of server.features() (currently sha256() only). Like for block and transaction hashes, when converting the big-endian binary hash to a hexadecimal string the least-significant byte appears first, and the most-significant byte last.

For example, the legacy Bitcoin address from the genesis block:

1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa
has P2PKH script:

76a91462e907b15cbf27d5425399ebf6f0fb50ebb88f1888ac
with SHA256 hash:

6191c3b590bfcfa0475e877c302da1e323497acf3b42c08d8fa28e364edf018b
which is sent to the server reversed as:

8b01df4e368ea28f8dc0423bcf7a4923e3a12d307c875e47a0cfbf90b5c39161
By subscribing to this hash you can find P2PKH payments to that address.

Can anybody explain what are these numbers:

6191c3b590bfcfa0475e877c302da1e323497acf3b42c08d8fa28e364edf018b

8b01df4e368ea28f8dc0423bcf7a4923e3a12d307c875e47a0cfbf90b5c39161

and how to get them?

Может плохо искал, но не нашел ничего толкового по этому вопросу.

В планируемом интернет-магазине предполагается для каждого заказа генерировать отдельную пару private key + address для приема платежей.
Очень надеюсь платежей будет много, только вот что с ними дальше делать?
Переводить биткойны с каждого адреса в обменник или сваливать все на один адрес и потом в обменник будет стоить достаточно дорого, так как transaction fee на каждом адресе будет соизмерима с переводимой суммой.

Уверен, я не первый, кто сталкивается с этой проблемой. Пожалуйста, подскажите, как с этим бороться или ткните меня носом в какой-нибудь пост пятилетней давности, где все это было описано.

Заранее благодарю!!!
