Method, computing unit and system for token-based information exchange

A computing unit for token-based information exchange with at least one other computing unit of at least one second entity, wherein the computing unit comprises communication means for exchanging information with at least one other computing unit, memory unit for storing portions of computer code containing instructions to be executed by a processing unit, and wherein the processing unit is configured to:

• obtain a token set including at least one token associated with the first entity and a token set including at least one token associated with the at least one second entity, wherein each entity is associated with at least one token set,
• cluster the token set associated with the first entity by dividing the token set into at least two clusters for forming at least two token subsets corresponding to said at least two clusters,
• request information on one or several tokens associated with the at least one second entity from the computing unit of the at least one second entity,
• receive information on said one or several tokens-from the computing unit of the at least one second entity, wherein the information is received from a primary cluster associated with the at least one second entity, wherein the primary cluster is a cluster comprising a previously utilized cluster during a previous token-based information exchange event,
• determine an active cluster associated with the first entity, the active cluster being one of said at least two clusters,
• modify the token subset associated with the determined active cluster of the first entity at least partly with information on the received one or several tokens associated with the second entity, and
• limit the number of tokens per information exchange to at least 1 token up to 5% of the tokens in the primary cluster.

A system comprising

• a computing unit of a first entity, wherein the computing unit of the first entity comprises a hardware processor,
• a computing unit of at least one second entity,
• the computing units of said entities are configured to exchange information utilizing tokens, wherein, in the system
• token sets are configured to be obtained by said computing units for associating with said entities,
• said token sets of the computing unit of the first entity is configured to be clustered by dividing the token sets into at least two clusters, by the respective computing unit for forming at least two token subsets corresponding to said at least two clusters,
• information on one or several tokens associated to the at least one second entity from the computing unit of the at least one second entity is configured to be requested, wherein the information is received from a primary cluster associated with the at least one second entity, wherein the primary cluster is a cluster comprising a previously utilized cluster during a previous token-based information exchange event,
• information on the one or several tokens from the computing unit of the at least one second entity is configured to be received by the computing unit of the first entity,
• one of the clusters of the first entity is configured, by the computing unit of the first entity, to be determined as an active cluster, the active cluster being one of said at least two clusters,
• the token subset associated with the active cluster of to the first entity at least partly with information of the received token associated to the at least one second entity are configured to be modified by the computing unit of the first entity,
• the modified token subset is configured to be utilized in a service, and
• a number of tokens per information exchange is limited to at least 1 token up to 5% of the tokens in the primary cluster.
