An example operation may include one or more of generating, by a blockchain node, an asset containment world-state by execution of a linear-time ingestion algorithm, detecting, by the blockchain node, an asset aggregation or disaggregation event, updating, by the blockchain node, the world-state based on the asset aggregation or disaggregation event, and computing supply-chain metrics based on the updated world-state.

Computation of containment relationships

An example operation may include one or more of receiving, by a resolver node, asset data to be recorded on a blockchain, executing, by the resolver node, a smart contract to apply an asset data validation format to the asset data, rejecting, by the resolver node, non-conforming asset data from being stored on the blockchain based on the execution of the smart contract, and accepting the asset data validated by the smart contract.

Resolution of conflicting data

An example operation may include one or more of receiving, by a document processor node, a document and a signed digital receipt identifying an owner of a version of the document associated with a blockchain transaction, verifying, by a document processor node, the version of the document based on the signed digital receipt, and executing a smart contract to enable a conflict-free document versioning based on a hash of the document recorded on a ledger of the blockchain.

Conflict-free version control

An example operation may include one or more of receiving, by a retailer node, an encrypted inventory of goods data from a plurality of supplier nodes over a blockchain network, computing, by the retailer node, an ordering proportion based on the encrypted inventory of goods data, generating, by the retailer node, an ordering policy based on the ordering proportion, and executing a smart contract to order goods from the plurality of the supplier nodes based on the ordering policy.

Upstream visibility in supply-chain

An example operation may include one or more of receiving, by a file processing node, a document file identification (ID) from a file owner node over a blockchain, acquiring, by the file processing node, a file storage plan executable script and an encrypted symmetric key for the document, decrypting the symmetric key by the file processing node, and executing the file storage plan executable script using the decrypted symmetric key as an input.

Preservation of privacy in large datasets

An example operation may include one or more of detecting, by a promotion processor node, a delivery of a trade promotion token by a retailer node on a blockchain, and executing, by the promotion processor node, a smart contract to: apply the trade promotion token to a purchase item and transfer incentive assets based on the trade promotion token to the retailer node and to a corresponding manufacturer node.

Product exploration-based promotion

An example operation may include one or more of acquiring, by a retailer node, an inventory data from a supplier node over a blockchain network, receiving, by the retailer node, outstanding orders data of the supplier node, generating, by the retailer node, an order distribution policy based on the inventory data and the outstanding orders data, and executing a smart contract to order goods from the supplier node based on the ordering policy.

An example operation may include one or more of receiving, by a resolver node, from at least one user node assets to be recorded on a blockchain, executing, by the resolver node, a smart contract to reject non-conforming assets from being stored on the blockchain based on a set of rules defined by an asset validation format, determining, by the resolver node, events and transactions related to the rejected assets, and allowing the at least one user node to tag the rejected assets, the events and the transactions related to the rejected assets as contradictory.

An example operation may include one or more of receiving from a user node, by a blockchain processor node, a document access request containing a document ID, acquiring, by the blockchain processor node, from a blockchain ledger an encrypted URL of the document and a source hash of the document based on the document ID, verifying, by the blockchain processor node, a document received from a document owner's node storage based on a decrypted URL of the document and, in response to the verification, transmitting the document received from the document owner's node storage to the user node.

An example operation may include one or more of receiving a data file submitted by a node, the data file comprising information about an event-driven process for a chain of nodes, retrieving an entitlement mode of the data file from a data block that is stored among a hash-linked chain of data blocks on a distributed ledger, determining access rights of the data file with respect to another node in the chain of nodes based on the retrieved entitlement mode of the data file, and transmitting information about the event-driven process to the other node based on the determined access rights of the other node.

Dynamic entitlement for blockchain data

An example operation may include one or more of marking a document, by a user node, to be included into a collection of documents, determining, by the user node, a business process step associated with the document based on a user mark, and executing a transaction to store a hash of the document onto a ledger of a blockchain, wherein a Merkle tree hash is generated and tagged on the ledger with details of the business process step.

Document verification

An example operation may include one or more of releasing, by a subscription service node, at least one blockchain transaction to a plurality of subscribing blockchain nodes requiring direct entitlement access, executing, by the subscription service node, a smart contract to calculate secondary entitlements triggered by the at least one blockchain transaction, determining, by the subscription service node, portions of second entitlement data sets allowed to be accessed by a subset of the plurality of the subscribing blockchain nodes, and sending verification data to the plurality of the subscribing blockchain nodes for verification of the second entitlement data sets.

Subscription service for networks

An example operation may include one or more of acquiring, by a promotion processor node, consumer exploration of a product data from a blockchain, determining, by the promotion processor node, features of the product, receiving, by the promotion processor node, a promotion plan from at least one product retailer node, and executing a smart contract to generate a plurality of promotion tokens based on the features of the product and the promotion plan.
