Who is this for? Yourself, or other people? If I use Tor, I wouldn't rely on a third party but just bookmark the link. Anything that makes Onion links easy to remember introduces an attack vector. It's not supposed to be remembered.
No, it's for sharing with other people like I said.
I am already bookmarking all websites I use all the time, this also protects me from potential phishing scam fake websites.
Just like Bitcoin address, i don't expect there are ways to make onion link become easy to remember without involving third party. QR code works fine on computer/laptop, but user need to take few extra steps depending on which application they use. The only remaining idea i have is showing image which has both QR code and onion link.
Problem with QR codes is they are not always compatible when generated with different programs.
I remember I tried to share one Bitcoin address from one app and it was not working because second app was not registering this custom QR code.
I haven't been keeping up with the Tor scene recently, so I'm not up to date on the latest developments. However, I'm curious about what happened to the "Onion Names" concept that was supposed to be integrated into all newer versions of Tor Browser, if I'm not mistaken. I remember reading about it some time ago, but I'm currently unable to find anything useful except for this article from SecureDrop:
https://securedrop.org/news/introducing-onion-names-securedrop/I never heard about this this, but they claim this is open source system, so I might do deeper investigation.
Good idea.
Is this based on ethereum network?
Maybe there is some alternative that works on bitcoin blockchain or on second layer solution for bitcoin,
