Trust group
From Organic Design wiki
A group of people who all trust each other. People can belong to many trust-groups which all form a trust-network. Information is able to pass safely and securely between any two people in the network because the route can be divided up such that information only ever passes between people who trust each other.
Trust-groups can be formalised into single entities that can trade and own financial accounts or assets, the type of entity best suited to such a group is a trust. Trusts can be formed purely out of contracts formed between the members of the trust-group.
