Abstract
A method of making a decision on a blockchain is disclosed. First public keys are received from each of a plurality of participants (A, B, C), wherein each first public key represents a possible selection by a participant and is related to a corresponding first private key by a cryptographic operation having a homomorphic property. The first public keys are combined to generate second public keys, wherein each second public key represents a possible decision based on a combination of possible selections. Third public keys, corresponding to the second public keys, are communicated to the participants. A voting blockchain transaction is generated (Tvoting), wherein an input of the voting transaction is a script executable by means of a digital signature corresponding to a first private key of each of a plurality of the participants, wherein each first private key represents a selection made by the participant. An output of the voting transaction is a script representing a decision based on the selections made by the participants. A payment blockchain transaction (Tpayment) is generated for transferring a first digital asset, wherein execution of an output of the payment transaction requires a digital signature corresponding to a third public key corresponding to the decision of the voting transaction.
