An approach for blockchain transaction processing using generative cryptograms for bi-lateral and Multi-lateral transactions may be provided. The approach may include, the use of decentralization ledger storage, negating the need of repetitive storage while preserving the need for data redundancy. A generative cryptogram may provide verification of processed blocks and file handles or storage address schemes of the ledger storage. The approach creates a cryptogram which is added to transaction processing, post processing and commits to the ledger. In the approach, the cryptogram is the only version of storage pointer and is utilized in subsequent transaction processing without the need for extensive compute and latest cryptogram is all that would be needed for transaction processing.

A contribution evaluation method, system, and computer program product that evaluates the contribution of each participant-computing device in the federated learning scheme based upon the quality of model updates received from the participant, measured by the accuracy improvement of FL model with applying the participant's model updates.

An example operation may include one or more of receiving, via a first blockchain peer, a request to verify an identity of a user, performing, via the first blockchain peer, an identity validation of the user via a know your customer (KYC) service provider of a blockchain network, determining whether a digital identity of the user has been previously stored by another blockchain peer on a blockchain of the blockchain network, in response to a determination that the digital identity of the user has not been stored on the blockchain, creating a non-fungible token (NFT) that identifies the user, and appending information about the identity validation of the user to a structure of the NFT and storing the NFT in a block of the blockchain.

Mechanisms for performing intelligent federated machine learning (ML) model updates are provided. A plurality of ML model updates, and a plurality of dataset sketch commitment data structures (sketches), are received from a plurality of participant computing systems. Each sketch provides statistical characteristics of a corresponding local dataset used by a corresponding participant to train a local ML model. A potentially malicious participant identification operation is performed based on an analysis of the plurality of sketches to identify one or more potentially malicious participants based on differences in sketches. ML model updates received from participant computing systems identified as potentially malicious participants are discarded to thereby generate a modified set of updates. The federated ML computer model is updated based on the modified set of updates.

A processor may record one or more transaction proposals regardless of validity of the one or more transaction proposals. The processor may separate a transaction validation into a series of steps. The processor may validate, asynchronously, one or more transactions respectively associated with each of the one or more transaction proposals based on the transaction validation.

A processor may define an available resource set in the blockchain network. The available resource set may be the one or more peers. The processor may collect one or more metrics associated with the one or more peers in the blockchain network. The processor may analyze the one or more metrics and may identify a first workload level for the one or more peers. The processor may determine an optimal status for a first particular peer of the one or more peers, based in part on the available resource set and the first workload level. The processor may compare the optimal status to a current status of the first particular peer. The processor may determine if the optimal status and the current status are different. The processor may execute a status change of the first particular peer from the current status to the optimal status.

A system and related method coordinate data and transactions between an enterprise transaction system (ETS) of an enterprise and a blockchain network (BN). A coexistence mediator intercepts an ETS transaction comprising ETS transaction information (ETS-TI) associated with an enterprise. The ETS-TI includes transaction context information (ETS-TCI) regarding the ETS transaction. The system determines an ETS transaction context from the ETS-TCI. Responsive to determining the ETS transaction context represents an in-flight ETS transaction, rerouting, the coexistence mediator reroutes the transaction from the ETS to the BN. The rerouting comprises converting the ETS-TI to BN transaction information (BN-TI), and interfacing with the BN to record a processed BN transaction as a transaction record. The coexistence mediator, upon recording the BN transaction, provides a new BN-TI associated with the BN transaction. The new BN-TI comprises a BN transaction id. The system further switches the ETS transaction context to a BN transaction context.

An example operation may include one or more of receiving a request for executing a trade transaction with a digital token, determining to execute an additional verification on the digital token based on one or more of a newness of the digital token and a lack of data on the digital token, querying a blockchain ledger associated with the digital token for one or more additional data attributes of the digital token, and determining whether or not to execute the trade transaction with the digital token based on the one or more additional data attributes of the digital token queried from the blockchain ledger.
