The embodiment of the application, which belongs to the technical field of identity verification, discloses a block-chain-based information verification method and apparatus. The method comprises: corresponding effective signature information is generated based on to-be-verified information and is stored into a block chain; corresponding non-effective signature information is generated based on the to-be-verified information and is stored into the block chain; a verification request message that is generated by a verification node based on the effective signature information or non-effective signature information stored into the block chain is received; and the verification request message is verified and an information effective message or an information non-effective message is returned to the verification node according to a verification result. Therefore, on the basis of the information verification way provided by the invention, both security and privacy of information are considered and realized.
