Meta's Instagram app, Threads, has been getting plenty of new features added on a regular basis. One of these is the ability to verify your Threads profile on Mastodon, which is due to both platforms being available on the fediverse.
The fediverse is a network of decentralized servers that support 'rel=me' links, which are links that are related to each other and therefore can be used to point to each other. This allows for a self-verification system that doesn't require outside approval, and can therefore be established must faster.
