The invention discloses a block chain logistic source tracking anti-fake method based on NFC (Near Field Communication). The method is based on a source tracking anti-fake system and comprises a publicly verifiable block chain background system, a block chain gateway system, a mobile intelligent read-write terminal, a cash databank and an NFC (IC) (Integrated Circuit) or internal NFC (IC) anti-fake label. The method comprises the following steps: generating an anti-fake label; initializing the anti-fake label; activating by a producer; adding information by a middleman; and verifying by a final user; after the anti-fake label is scanned at the read-write terminal each time, substituting a hidden password on an NFC chip and a corresponding visible password in a block chain by newly generated hidden passwords and visible passwords, and disabling the used hidden password and the visible password. By adopting the method, problems of trust dependence of users upon nodes in different product logistic procedures, trust dependence upon a third party, dependence upon techniques, trust dependence upon anti-fake labels and trust target deviation are solved, the introduction threshold is low, and the anti-fake security and reliability can be greatly improved.
