Abstract
An example operation may include one or more of identifying a current tool configuration used by a tool device to construct semiconductor devices, retrieving a smart contract stored in a blockchain to identify whether an updated tool configuration exists, responsive to identifying the updated tool configuration, transmitting an update that includes the updated tool configuration to the tool device, and responsive to receiving the updated tool configuration at the tool device, initiating construction of the semiconductor devices.
