Hi GNU social! I signed up via Mastodon because I like to try the difference decentralized social networks that are out there.
Recent projects I've been involved with:
Bitseed - www.bitseed.org - plug and play Bitcoin full node servers.
Blockstack - www.blockstack.org - platform for building decentralized applications, with built-in decentralized DNS and PKI.
Decentralized Web Summit - www.decentralizedweb.net - conference bringing together developers and thinkers working on decentralized tech
