@erictan90 after I look around about Umbrel, based on this, Umbrel doesn't allow public incoming connections. Though I don't know much about how Umbrel is configured and how Docker works. But probably, that is the reason why you didn't get any inbound connections, which the node doesn't act as a listening node.

No, Bitnodes only lists Bitcoin nodes.

That comes from your own node. Electrs are using a P2P bitcoin connection, which makes it show as an inbound connection.

does anyone know why it is not possible to disable these 3 options in the umbrel node?

especially the last option 'remote access' to the tor network would be very interesting...
is this generally not possible for the current version or is it maybe somewhere in my settings?

That tool is more suitable for checking whether your node accept incoming connection. If you just want to check whether bitnodes.io already detect your node, you could use search bar on leaderboard page (https://bitnodes.io/nodes/leaderboard) instead.

I suspect the only inbound connection you got is coming from Electrs, you can verify it using bitcoin-cli getpeerinfo and search "subver": "electrs",

At least, that is the issue I also encounter on my Raspibolt node, which I suppose Umbrel does only run over Tor connection. It usually happens because I got a bad internet connection, and it is usually fixed by just restarting the Tor service. After that, I leave it half an hour or just a couple of hours, and then the node usually got the inbound connections back.

I don't know for sure about your node, but you can also try to restart the Tor service if you want:

I sold my house.  I paid my friend to buy 20 bitcoins.  He bought from a place called Tour.  From an exchange called crc.  This exchange is in the dark web space.  My friend says that the exchange has transferred bitcoins to its user.  But he can not transfer from the user to the wallet.  He has assured me that he has received the bitcoins.  But from its dark web user can not transfer it to the wallet.

I've always been curious to know how often the source code is checked? When does a new release come out? Who is doing this? How many people check the source code? How much can they be trusted?

Sorry for so many questions. I wanted to know, at least superficially, how this is implemented.

It seems to me that if this is implemented, it will be done differently. The regulator will create conditions under which people themselves will be forced to give their bitcoins or part of it in the form of taxes.

Also I don't think trezor can force people to update their firmware if they don't want to. I guess they could make it incompatible but since there are other drivers that can be used and it's open source, that makes things a lot harder for them to succeed in an attack.

Both Trezor's software and firmware are open-source. If they add malicious code, people would find out[1][2]

Hello,

I would like to write down my seed phrase but I am hesitating between writing it on a sheet with a pen or typing it on my notepad app on my computer and print it ?
Which one will last longer ?

Thanks !

Not 100% sure since I have tinkered with mine a lot, all I can say is mine DID before I took it offline last month.
Take a look here: https://community.getumbrel.com/t/is-there-a-way-to-increase-the-number-of-peers/5150

You might want to post a question there too and see. The community is active and willing to help.

Side note, before opening ports make sure you understand the security implications of letting ANY inbound traffic into your network.

While it should be plug and play,i have few recommendation/concern.
1. Since you already download whole blockchain, you could use it on myNode to save time/bandwidth. You can check their guide at https://mynodebtc.github.io/bitcoin/data-from-other-node.html or contact their premium support about how to do it.
2. Tor is censored on some country/ISP. If it happened on your country/ISP, configuring Tor manually might be needed.
