The embodiment of the invention provides a data storage method and device based on a transaction weight, relates to the field of data storage and can also be applied to the financial field, and the method comprises the following steps: obtaining an initialized security parameter according to an initialized security parameter request and a data storage request sent by a user; sending the initialized security parameter and the data storage request to a decentralized storage node, and performing content identification processing; sending the initialized security parameter and the data storage request to a block chain node, so that the block chain node initializes a consensus request based on weight distribution, updates block information based on a directed acyclic graph according to the data storage request and the data content, generates a corresponding verification parameter, and returns the verification parameter to the client node; according to the invention, a directed acyclic graph (DAG)-based framework i
