use verification forms other than lightning

[galets]

Lightning wallets are not very well established. In order to post, a small amount of satoshis are requested via lightning. This is an issue to most users, even those who are familiar with crypto. This is a request to allow something other than lightning for validation. This could be:

• regular BTC (expensive)
• some cheap blockchain (bitcoin cash, doge)
• sign a message using key from wallet having balance, or sign a message using a known GPG key
