Abstract: Techniques for repair and/or recovery of computer program(s) installed on a programmable device using a distributed ledger that is based on cryptography and blockchain technology are described. One or more self-reliance logic/modules can commit, to a distributed ledger that resides on interconnected devices, records of watchdog communications between the devices. One or more of interconnected devices may include a respective self-reliance logic/module. The logic/modules can use the records of the distributed ledger to check that computer program(s) on the interconnected devices are operating as expected. When a self-reliance logic/module fails to respond to a watchdog communication, the distributed ledger can be updated to include this failure. A self-reliance logic/module can determine, based on the distributed ledger and/or the failure, that an installed computer program is faulty. Furthermore, a self-reliance logic/module can initiate one or more software recovery services based on the determination. Other advantages and embodiments are described.
