Method, system and computer program for verifying false or misleading information

A system for verifying false or misleading information, which comprises:

• a plurality of computing nodes that implement a decentralised blockchain;
• at least one processor configured to create a Non-Fungible Token for voting and associate it to one or more information records to be verified, and to distribute said created Non-Fungible Token and said one or more information records to be verified to a plurality of computing nodes that implement a decentralised blockchain;
• one or more computing devices that are external to the decentralised blockchain;
• wherein a set of computing nodes of the plurality of computing nodes of a first type is configured to establish a first verdict of whether said one or more information records to be verified include false or misleading information by means of checking different parameters of the information record(s), providing as a result of said first check a series of metadata per information record;
• wherein a set of computing nodes of the plurality of computing nodes of a second type is configured to establish a second verdict of whether the information record(s) include(s) false or misleading information by means of checking said series of metadata;
• each computing node of the first type and of the second type has equal voting power in establishing said first verdict and second verdict, and the first verdict and second verdict are encoded in the decentralised blockchain in the form of a Smart-contract;
• and
• wherein the at least one processor is further configured to add the first verdict and the second verdict such that if the result of the second verdict confirms the result of the first verdict, a final verdict of whether the information record(s) to be verified include(s) false or misleading information is set and published;
• and if the result of the second verdict does not confirm the result of the first verdict, said one or more computing devices are notified of a conflict between the first verdict and the second verdict, wherein at least one of said computing devices is configured to perform, through a plugin installed in a browser of the computing device, a final certification of the first and second verdicts by adding supplementary information to same.
