I'm looking for information about how wallets can be fingerprinted based on locktime, RBF, etc... but there isn't a wealth of information available.
Can somebody point me to some articles/docs/wiki ?
Thanks!

A lot of people are using Electrum though, that's what they are used to. Personally, I would like to only use Bitcoin Core with my Coldcard but I'm so used to Electrum now it's hard to switch. Core uses sats / kilobyte for some reason while everything else uses sats / vbyte which might seem like a small thing but I hate it. Also you can't freeze addresses in Core.

True about the pruned node, but this is not an issue when setting up a new wallet. If you have an unpruned node you can prune it after you've connected Elecrum.

Just wanted to plug a nice piece of software that I've come across: Bitcoin Wallet Tracker - Electrum Plugin

It allows you to connect Electrum directly to your node without having to set up and Electrum Server. You can use it with a pruned node and with multiple Electrum Wallets, only limitation is that you can only use it with a hardware wallet.

My desktop Electrum is connected to myNode running Electrs and Samourai to Dojo on myNode. I couldn't get the android version of electrum working with myNode yet so that's using public servers.

edit: I managed to sweep using electrum desktop, all I had to do was add p2wpkh: in front of the private key.

still looking into why it doesn't work on android, with samourai or bitcoin core...

Ok so a little update... I created and printed out the paper wallet, it has the address bc1qrwc85tjunwql9zu9gew3q7knf70mv73tghtqyr and as you can see I deposited a small amount of Bitcoin on it. I tried creating a watch only wallet in Electrum (android) to see if it worked and... nothing. No funds on that address whatsoever. I tried sweeping the wallet with Electrum (both android and desktop) and Samourai Wallet and while they recognize the private key they don't find any UTXO...

What the fuck is going on?

edit: If I use the Electrum desktop wallet to create a watch only wallet and import the address it does recognize the UTXO..
edit: I can't sweep the private key in Bitcoin Core either

I'm talking about the build in paper wallet generator on the device itself.

Thanks for all the good advice here. https://iancoleman.io/bip39/ seemed the best option but I just discovered that my coldcard has a built in paper wallet generator so I'm going to use that.

A friend of mine recently had his first child and we are all going to visit and bring gifts. I want to gift $10 in btc not to be accessed until his kid is an adult, by which time it will be worth a lot more or nothing at all.

I'm trying to figure out the best way to do this so that in 20 years the btc can still be recovered. Do I make a wallet, write down the seed phrase, send in some bitcoin and then destroy the wallet? Or do I write down the private key for the specific address where I send the bitcoin to? And which wallet? Electrum doesn't use BIP39, but a BIP39 seed phrase isn't guaranteed to work with every BIP39 compatible wallet either... What about derivation paths?
Is there a secure way to generate a paper wallet offline with a QR code and everything?

I have no experience with paper wallets so any advice is welcome.

That's funky, point my Raspberry Pi with ElectrumX to my desktop and then point my Electrum on my desktop to my Raspberry Pi :-) But that's not what I want to do. I have Bitcoin Core running on my Pi and I would like to run an electrum server on the same device. Do you think my 8GB Pi 4 can handle ElectrumX + Bitcoin Core?

I want to set up an Electrum server for my desktop and mobile Electrum wallets. If I can offer it over Tor to strangers like a do with Core that's a nice donation to the network. A lot of Electrum servers must be honeypots so it would be great if more trustworthy servers existed.

The question is if I have the hardware run ElectrumX? I have a Pi 4 with 8GB of RAM, do you think this is sufficient hardware to run Electrumx? I doubt I'll get a lot of incoming connections since I'll only be offering it as a hidden service.

Edit: Esplore seems to require 100s of GB of data so that's a no, since my SSD is 1TB and half full already.

I'm looking to install an Electrum server. Only condition is it can be used to serve multiple wallets at the same time so Electrum Personal Server is not an option. Currently I'm looking at Electrumx and Electrs

1. Are there any other projects I should be aware of?
2. Can I use Electrs to serve random users from across the internet like I can with Electrumx?
3. Can I create a Tor hidden service for both? Clearnet is not an option.
4. What are the general benefits and drawbacks for both?

How would you use this in relation to managing bitcoind?

No I only used the drive with Raspberry Pi OS before. Just plugged it in and it worked although maybe they formatted it for Windows by default during production.

I'm not familiar with symbolic links yet.

I deleted everything on the drive and formatted in ext4.

But isn't this is only relevant if you accept incoming connections? If I'm not mistaken, Bitcoin will not accept connections when running behind a proxy, except if you define listen=1.

So adding bind=127.0.0.1 does nothing? What's the point of this setting then?

I have a node running with Tor running as a service and proxy=127.0.0.1:9050 in the bitcoin.conf file. Does it make any difference if I add bind=127.0.0.1 and/or bind=127.0.0.1:9050 to the file?

I formatted the drive to ext4 and it still wouldn't work, but now I was able to chown /mnt/bitcoin so I finally started IBD!!

I can confirm that it only impacts /blocks which is a pitty but ok I put the entire datadir on the ssd then
