Method for analyzing data using a blockchain, a data provider and a data customer therefor

A data provider system using a blockchain comprising:

• a data storage system configured to store a plurality of data sets in a distributed manner using a cluster of nodes;
• a data processing system configured to process the plurality of data sets in a distributed manner using the cluster of nodes;
• a token control system configured to control processing of the data processing system based on a token in a distributed manner using the cluster of nodes;
• and
• a blockchain application configure to deploy a smart contract to the blockchain, the smart contract associated with an access key configured to authorize access to the smart contract,
• wherein, the data provider system is configured to receive a request for executing code from a data customer for data sets of the data provider selected by the data customer, wherein the request for executing code includes the code from the data customer to be executed by the cluster of nodes, the access key, and a balance amount of token which the data customer currently has, wherein the code to be executed includes a set of computational operations;
• wherein, when the deployed smart contract is configured to receive the request for executing code from the data customer for certain data sets of a data provider, the deployed smart contract estimates amount of token required for executing the code for the certain data sets,
• wherein the token control system is configured to control, in a distributed manner using the cluster of nodes, execution of the code for the certain data set based on balance amount of token while the balance amount of token is greater than the estimated amount of token, wherein controlling execution of the code for selected data sets further comprises monitoring whether the balance amount of token which the data customer currently has is enough for executing each computational operation and, based on a monitored balance amount of token, controlling whether to continue execution of each computational operation or not, and wherein the token control system is configured to manage the balance amount of token, wherein the balance amount of token is updated in a distributed manner after execution of each computational operation at each respective node of the cluster of nodes, wherein the balance of amount of token is reduced by a respective amount of token used in parallel by each respective node of the cluster of nodes.

A system comprising:

• a data customer system using a blockchain comprising:
• a blockchain application configured to request for published metadata of available data sets among a plurality of data sets of a data provider in a data storage system to the blockchain;
• and
• a token application configured to select certain data sets using the metadata of available data sets and request for executing code for the selected data sets, the request including a balance amount of token which a data customer currently has, and an access key, to a smart contract;
• and
• a data provider system using the blockchain comprising:
• the data storage system configured to store the plurality of data sets in a distributed manner using a cluster of nodes;
• a data processing system configured to process the plurality of data sets in a distributed manner using the cluster of nodes;
• a token control system configured to control processing of a data processing system based on token in a distributed manner using a cluster of nodes;
• the blockchain application configured to deploy the smart contract to the blockchain;
• wherein the smart contract is configured to associate with the access key, and the access key is configured to authorize access to the smart contract,
• wherein in a case that the token application is configured to receive the access key from the smart contract, the token application writes the code for the selected data sets into the smart contract,
• wherein the code includes a set of computational operations and the metadata includes information of identifying each data set in the data storage system,
• wherein, the data provider system is configured to receive a request for executing code from the data customer for data sets of a data provider selected by the data customer, wherein the request for executing code includes the code from the data customer to be executed by the cluster of nodes, the access key, and the balance amount of token,
• wherein, when the deployed smart contract is configured to receive the request for executing code from the data customer for certain data sets of the data provider, the deployed smart contract estimates an amount of token required for executing the code for the certain data sets,
• wherein the token control system is configured to control, in a distributed manner using the cluster of nodes, execution of the code for the certain data set based on the balance amount of token while the balance amount of token is greater than the estimated amount of token, wherein controlling execution of the code for the selected data sets further comprises monitoring whether the balance amount of token which the data customer currently has is enough for executing each computational operation and, based on a monitored balance amount of token, controlling whether to continue execution of each computational operation or not, and
• wherein the token control system is configured to manage the balance amount of token, wherein the balance amount of token is updated in a distributed manner after execution of each computational operation at each respective node of the cluster of nodes, wherein the balance of amount of token is reduced by a respective amount of token used in parallel by each respective node of the cluster of nodes.
