A method for analyzing data using a blockchain, a data provider and a data customer therefor are disclosed. The method analyzing data using a blockchain is provided wherein a plurality of data sets is stored and processed in a data storage in a distributed manner using a cluster of nodes. The method comprises steps of deploying a smart contract to the blockchain according to a request from a data customer, receiving a request for executing code for data sets selected by a data customer, estimating an amount of token required for executing the code for the selected data sets in the data storage, and controlling, in said distributed manner using the cluster of nodes, execution of the code for the selected data sets based on the balance amount of token while the balance amount of token is greater than the estimated amount of token. The request for executing code includes code to be executed and a balance amount of token which the data customer currently has. The code to be executed includes a set of computational operations. The balance amount of token is updated after execution of each computational operation in said distributed manner. The amount of token represents number of units for an entity which controls computational complexity of the code requested by the data customer.
