You can't address the risk that whoever owns the domain will stop renewing it, or otherwise stop making the web gateway available. Best-case scenario is that it becomes possible to find out what URL a shortened link used to point to, for as long as the underlying blockchain lasts, but if a regular user clicks on a link after the web gateway shuts down then they'll get an error message or end up on a domain squatting site, neither of which will provide any information about how to get where they want to go.
These days one can register a domain for ten years, and have it auto-renew with prefunded payments that are already sitting in the account. This is what I did for the URL shortener I am developing.
The same would have to be done for the node running the service, and it too has been prefunded with a sitting balance.
Granted, there still exist failure modes, and so the bus factor needs to be more than one, but the above setup can in all probability easily ride out a few decades with the original person forgetting about it. In principle, a prefunded LLM with access to appropriate tooling and a headless browser can even be put in charge to address common administrative concerns.
I mean yes the web gateway can shut, but honestly like atleast with goo.gl if things go down, then there is no way of recovering.
With the system I am presenting, I think that it can be possible to have a website like redirect.com/<some-gibberish> and even if redirect.com goes down then yes that link would stop working but what redirect.com is doing under the hood can be done by anybody so that being said,
it can be possible for someone to archive redirect.com main site which might give instructions which can give a recent list on github or some other place which can give a list of top updated working web gateways
And so anybody can go to archive.org, see that's what they meant and try it or maybe we can have some sort of slug like redirect.com/block/<random-gibberish> and then maybe people can then have it be understood to block meaning this is just a gateway (a better more niche word would help)
But still, at the end of the day there is some way of using that shortened link forever thus being permanent in some sense.
Like Imagine that someone uses goo.gl link for some extremely important document and then somehow it becomes inaccessible for whatever use case and now... Its just gone?
I think that a way to recover that could really help. But honestly, I am all in for feedback and since its 0 fees
and as such I would most likely completely open source it and neither am I involved in this crypto project, I most likely will earn nothing like ever even if I do make this, but I just hope that I could help in making the internet a little less like a graveyard with dead links and help in that aspect.
