Qbix and Intercoin were founded to help build web-based online communities, and secure them with crypto, respectively. As our investor presentation explains, once you have a social network, you can roll out a payment network on top of it. But crypto can power a lot more than secure payments; it can also power secure elections, governance, and analytics.
CommunityContract is a smart contract that provides a standard interface for managing who belongs to a community, and what roles they have. Other contracts, such as
VotingContract (elections) and
ControlContract (management) rely on this contract to handle the above concerns.
CommunityContract supports a hierarchical model, where an
owner can add and remove
admins, who can add and remove
members. However, other roles and permissions can be defined by
owners. In general the interface is below:
addMembers([members]) removeMembers([members]) addRoles([role], [members]) removeRoles([roles], [members]); getRoles(member) // member optional, all members have "member" role getMembers(role) // role optional memberCount(role) // role optional // owners only: createRole(role, displayName) canManage(role1, role2) // add and remove role transferOwnership(address)
Members are represented in a pseudonymous way by their Ethereum wallet addresses, and can themselves be either real users or smart contracts. For example, the
owner of a
CommunityContract can actually be an instance of
ControlContract that is managed, say, by 5 admins together, and any action taken by the owner account would have to be endorsed by at least 3 admins before it takes effect.
This is a very general-purpose implementation, that nevertheless implements a basic community that can be used by other smart contracts, either built by us or someone else.
Besides the technology, there are also social, economic and legal aspects to think about when rolling out community currencies and universal basic income. That is what we all discuss in the Intercoin community.
