Title: METHOD FOR MANAGING DATA IN A NETWORK OF NODES
Abstract:
The present invention further relates to a method for managing data in a network of nodes, wherein said network is a decentralized blockchain consensus network, said nodes of said network are interrelated with each other according to a tree-like structure, wherein the root node publishes a product contract description for a new product, said product contract description includes at least product information and product state information, and wherein said root node generates at least one product item for said new product by publishing a product item contract including at least item identification information, the product contract for said item, item state information and valid modifier information for information of at least one node to be able to modify the item state, wherein upon generating a new item for a product said root node updates the product contract description by including item information into said product contract description and wherein said publishing of said product contract description and said product item contract description is performed by sending transactions into said network, wherein said transactions are verifiable by the nodes in the network, said transactions each refer to a contract account, and wherein upon verification of a transaction by at least one node a verified transaction is added to the blockchain with its address.
