Have you heard of Mastodon yet? It's a federated social network (similar to Twitter) that has been slowly but steadily growing over the last two years. While it\'s not mainstream yet (only around 2.5Mill users), the technology underneath it (Activity Pub and JSON-LD) make it a very hopeful candidate for helping us escape the platform zombie apocalypse. In order to ensure long-term stability of such a federated network it may make sense to combine it with another new technology called decentralized identifiers (DID). Using DIDs we may be able to avoid the problems that Moxie mentioned in his well known blogpost on federation ("the ecosystem is moving"). The DID standard is the result of many years of work by rebooting-the-web-of-trust community.
