The invention discloses a public cloud system and method for realizing data transparency and traceability based on a block chain, and relates to the technical field of block chain traceability, to-be-chained data of each link is generated through a multi-signature mode, a block is generated for each link every preset block generation duration, and a block is generated for each link; each block stores verified to-be-chained data corresponding to the link, collects an abnormal traceability request, traces a block chain, generates single product traceability information, counts a batch abnormal proportion of a production batch corresponding to each purchased product, collects an abnormal product traceability information set corresponding to an abnormal production batch, and stores the abnormal product traceability information set corresponding to the abnormal production batch; performing statistics on abnormal statistical parameters of member nodes participating in each link in the abnormal product traceability
