The **wallet service** will have sent that event to those relays earlier, and the relays will hold it as a replaceable event. 3. When the **user** initiates a payment their nostr **client** create a `pay_invoice` request, encrypts it using a token from the URI, and sends it (kind 23194) to the relay(s) specified in the connection URI. The **wallet service** will be listening on those relays and will decrypt the request and then contact the **user's** wallet application to send the payment. The **wallet service** will know how to talk to the wallet application because the connection URI specified relay(s) that have access to the wallet app API. - 4.

However, it turns out that format is very bloated and convoluted, has way too many features and probably because of that it doesn't have many alternative implementations out there, and the ones that exist are not complete and don't look very trustworthy. Also it is very much a centralized format that can probably be changed at the whims of the Wikipedia owners. +Wikitext is [garbage](nostr:nevent1qqsqt0gcggry60n72uglhuhypdlmr2dm6swjj69jex5v530gcpazlzsprpmhxue69uhhyetvv9ujumn0wdmksetjv5hxxmmdqy28wumn8ghj7un9d3shjtnyv9kh2uewd9hsygpm7rrrljungc6q0tuh5hj7ue863q73qlheu4vywtzwhx42a7j9n5ueneex) and Markdown is not powerful enough (besides being too freeform and unspecified and prone to generate incompatibilities in the future). -On the other hand, Markdown has proven to work well for small scale wikis and one of the biggest wikis in the planet (which is not very often thought of as a wiki), [StackOverflow](https://stackoverflow.com) and its child sites, and also one of the biggest "personal wiki" software, [Obsidian](https://obsidian.md/). Markdown can probably deliver 95% of the functionality of wikitext. When augmented with tables, diagram generators and MathJax (which are common extensions that exist in the wild and can be included in this NIP) that rate probably goes to 99%, and its simplicity is a huge benefit that can't be overlooked. Wikitext format can also be transpíled into Markdown using Pandoc. Given all that, I think it's a reasonable suspicion that mediawiki is not inherently better than Markdown, the success of Wikipedia probably cannot be predicated on the syntax language choice. +Asciidoc has a strict spec, multiple implementations in many languages, and support for features that are very much necessary in a wiki article, like _sidebars_, _tables_ (with rich markup inside cells), many levels of _headings_, _footnotes_, _superscript_ and _subscript_ markup and _description lists_.
