    Abstract: A verification terminal includes a storage unit that stores partial block data. The partial block data is the latest data that a part of block data for update and addition in chronological order. The verification terminal selects a plurality of approval terminals to approve the partial block data stored in the storage unit. When a transaction included in the partial block data stored in the storage unit is updated by the verification terminal, the verification terminal transmits an approval request that requests the selected approval terminals to approve the updated partial block data to which the updated transaction and a hash value of the partial block data before updating are added. The verification terminal executes an update process of the partial block data based on approval results returned from the approval terminals in response to the approval request transmitted by the approval requesting unit.

    Abstract: In a verification terminal for verifying properness of an information item composed of a data string, a storage unit stores an own-terminal information item comprised of a data string, and a verification value generation unit generates a hash value of the own-terminal information item stored in the storage unit as an own-terminal hash value. A verification value acquisition unit communicates with at least one other verification terminal that should store an other-terminal information item t to thereby acquire a hash value of the other-terminal information item from the at least one other verification terminal as an other-terminal hash value. The other-terminal information item is conditioned to be identical to the own-terminal information item. A verification execution unit verifies properness of the own-terminal information item in accordance with whether the own-terminal hash value is consistent with the other-terminal hash value.

    Abstract: A heat storage unit or a heat storage system is a heat storage unit including: a heat storage portion having a first material with a strongly correlated electron system material; and a heat conduction portion having a second material higher in a thermal conductivity than the first material and being in contact with the heat storage portion. The heat storage unit may have a laminated structure in which the heat storage portion and the heat conduction portion are alternately laminated on each other. For example, a metal-insulator phase transition material or a transition metal oxide may be used as the strongly correlated electron system material. The second material may be metal or ceramics.

    Abstract: A composite heat storage material includes a heat storage material and an inorganic material. The heat storage material is made of a strongly correlated electron material that stores and dissipates heat via solid-solid phase transition. The inorganic material is different from the material of the heat storage material. The heat storage material and the inorganic material are mixed. The composite heat storage material can have characteristics of both the heat storage material and the inorganic material.
