U.S. Patent 11153092 was awarded to Commonwealth Scientific and Industrial Research Organisation on October 19, 2021 and is entitled “Dynamic access control on blockchain.” The first named inventor is Mark Staples of Acton, . The abstract contains an overview of the patent disclosure:

This disclosure describes dynamic access control using capabilities (via dynamic access control interface (150)) on a blockchain system (180). The blockchain data structure is a time-stamped list of blocks, chained together cryptographically. In this disclosure, capabilities can be recorded on a blockchain system (via capabilities storage (170)) and thus access propagation is known. This makes revocation of access achievable by recording a new transaction, which in effect removes the previous authorization. There will be no change to transaction history and instead a new transaction records (170) the current status of the capability. An example implementation on a blockchain system (180) is given in Ethereum, which allows programs called “smart contracts” to run as transactions. Link to Full Patent
