The present disclosure relates to a smart contract-based data transfer method, comprising the steps of: a data source encrypting data to be transferred based on a first mechanism to form encrypted data, and sending the encrypted data to a smart contract terminal; the smart contract terminal decrypting the encrypted data based on a second mechanism corresponding to the first mechanism to form the decrypted data, and processing the decrypted data by using at least one logic unit to form the resulting data; and the smart contract terminal sending the resulting data to a data-related party; wherein the at least one logic unit executes an instruction set to implement a contract logic, and the instruction set is stored in a blockchain.

Smart contract-based data transfer method and system

The present invention provides an electrical interconnection system comprising: a paddle card comprising a plurality of first contact pads positioned on a first surface of the paddle card and a plurality of second contact pads positioned on an opposite second surface of the paddle card; a first wafer comprising a plurality of first conductors each having a first contact portion; and a second wafer comprising a plurality of second conductors each having a second contact portion; wherein the first wafer and the second wafer are assembled together to have the first contact portion and the second contact portion face each other and be able to form a gap therebetween for accommodating at least part of the paddle card; each first contact portion is adapted to be in electrical contact with a corresponding first contact pad and each second contact portion is adapted to be in electrical contact with a corresponding second contact pad when the paddle card is at least partly accommodated in the gap.
