Claim 20:
21. The system of claim 16, comprising instructions to:
obtain a first role among multiple roles associated with a first user,
wherein the multiple roles are arranged in hierarchical levels,
wherein the first role indicates a subset of nodes that the first role can issue;

obtain a first node issued by the first user and a second user affected by the first node; and
determine whether the first node is valid by:
determining whether the first node issued by the first user belongs to the subset of nodes that the first role associated with the first user can issue;
obtaining a second role associated with the second user, a second hierarchical level associated with the second role, and a first hierarchical level associated with the first role;
determining whether a first hierarchical level among the hierarchical levels matches or is higher than the second hierarchical level; and
upon determining the first node belongs to the subset of nodes and determining that the first hierarchical level among the hierarchical levels matches or is higher than the second hierarchical level, determining that the first node is valid.
