In some implementations, a digital platform receives a request to execute an operation on a digital model. The digital platform generates a fungible idempotent token that uniquely identifies the request. The digital platform selects data that identifies one or more tools for executing the operation. The digital platform generates one or more nonfungible idempotent tokens associated with the data that identifies the one or more selected tools. The digital platform executes the operation on the digital model using the tools. While executing the operation, the digital platform determines whether to additionally execute the operation on the digital model based on a subsequent request. In response to determining that the additional execution of the operation has been requested while the operation is being executed, the digital platform prevents the additional execution.
