A gem that I have been following for a long time is Phore and I like to share it with you because I think the vision that the team has is really interesting.
Thanks to the decentralized marketplace, they will allow online purchases on a secure platform that maintains privacy and protects user data. Furthermore, the lack of intermediaries also makes it cheaper.
The platform is currently in beta and can be reached here: https://phore.io/marketplace/
The team is working on a new project that will be distributed to all PHR holders because the team's vision is also community centered.
