NUT06: Add Mint TOS to mint info #205
Conversation
There was a problem hiding this comment.
ToS is usually a veeery long document. I think it would be better to replace the tos field with tos_url and provide link to the document instead so the info response is not so big.
As a bonus the document can be easily formatted - let's say in HTML or PDF format.

You bring up a good point that including it directly in the info response would increase its size and as this is something that a wallet should fetch often we should avoid this. However, linking to a document without defining a structure or file type would make it very difficult for a client to render and show to an end user. I think the TOS should be just a text string to avoid making it difficult for a wallet to show when the mint is added. |
Maybe we should strongly recommend that ToS are in a format easily rendered by a browser/app such as plain-text, Markdown, PDF or HTML?
I don't think we can come up with any reasonable structure. Laws in different countries are different. Btw, I just checked and the current cashu.me (i know that's a wallet not a mint) ToS are currently around 11 KB and they are pretty minimal. |
Thinking more about this and HTML is probably too dangerous because it can contain some code to deanonymize user when opened :-( |

I would vote for URL. Wallets can render it as a web page. |
