Abstract: A data transaction apparatus includes a housing, a system circuit board comprising a tamper detection circuit disposed in the housing, and a tamper protection device configured to seal the system circuit board within the housing in a detachable manner. The tamper protection device includes a tamper resistant board and a resin layer covering the tamper resistant board, wherein the tamper resistant board includes a flexible substrate and a plurality of fence-like lead wires disposed on the flexible substrate. In one embodiment of the present disclosure, the tamper detection circuit is triggered to generate a secure response when a tamper event is detected.

Abstract: A block chain trading system includes a block chain platform coupled to a first bank end and a second bank end. When the block chain platform receives a token obtaining request from a user end, the block chain platform actives a token to the user end via the first bank end and records token activated information. When the block chain platform receives a token spending request from a dealer end, the block chain platform verifies the token spending request. If pass the verification, the block chain platform records token trading information. When the block chain platform receives a token liquidation request for the dealer end, the block chain platform sends token trading information to the first bank end. When the token is liquidated by the first bank end, the block chain platform records token liquidation information and retrieves the token from the dealer end.
