description: in which a capability describes a transferable right to perform one (or more) operations on a given object.
excerpt: >
  Computer scientist E. Dean Tribble stated that in smart contracts, identity-based access control did not support well dynamically changing permissions, compared to the object-capability model. He analogized the ocap model with giving a valet the key to one's car, without handing over the right to car ownership.
