Unlock is a protocol for memberships. It lets creator deploy their lock and sell access keys to anyone who wants to become member.
We believe donations and sponsorships are types of memberships. Supporters of open source projects and developers should receive a token for their contribution. With Unlock, they receive a non-fungible token which represents their membership.
These tokens can of course also be used to identify donors and maybe eventually offer them so unique content, features or schwag!
