The invention is applicable to digital equivalents of real-world resource or event, such as purchasing collectors' cards and partaking in games of chance that have pseudorandom outcomes. The requester of the token, who is the beneficiary of the product or outcome, makes a commitment prior to token creation and the corresponding proof is a factor in the outcome. The token defines a product or outcome having a format (F), wherein said format is determinable from a proof of the commitment, masked, and one of a plurality of formats (F). The token includes instructions configured to process the proof to unmask and determine the format. The instructions can be locked by a signature(s), and said signature is determined from the proof to unlock said instructions.
