The disclosed technology is generally directed to blockchain technology. In one example of the technology, a first transaction node of a hosted permissioned blockchain network is provisioned for a first consortium member of the hosted permissioned blockchain network. A shared pool of validator nodes of the hosted permissioned blockchain network is provisioned. The shared pool of validator nodes includes at least one validator node. The shared pool of validator nodes is shared among the plurality of consortium members. The validator nodes of the shared pool of validator nodes are configured for blockchain transaction validation based on a BFT consensus protocol. A second transaction node of the hosted permissioned blockchain network is provisioned for a second consortium member of the hosted permissioned blockchain network. Each transaction node of the hosted permissioned blockchain network is separate from each validator node of the hosted permissioned blockchain network.

Pooled validator node configuration for hosted blockchain network

The disclosed technology is generally directed to blockchain technology. In one example of the technology, a modified block is provided in response to at least an edit transaction that indicates a transaction in an original block in a blockchain. The modified block includes: transactions of the original block except the indicated transaction, a hash of the indicated transaction, and a header that includes a link to a hash of a block that precedes the original block. A new block is provided. The new block includes a reference associated with the edit transaction, and that the reference may include a link to the modified block. Subscription metadata associated with subscribers to changes in the transaction is retrieved from a stored registry. The subscribers are caused to be notified of the edit transaction.

Subscription to edits of blockchain transaction

A computing device includes a communications interface that communicatively couples the computing device with a plurality of other computing devices that collectively maintain a blockchain. A storage machine holds a plurality of blocks comprising the blockchain, where a particular block of the plurality defines a smart contract. The smart contract includes: (i) a first access criterion granted to an entity for a digital asset, and (ii) one or more functions that, when an associated condition is satisfied, change the first access criterion to a second access criterion, the condition being satisfied when one or more variables have specific values. A logic machine is configured to receive a current value of a variable and determine that the current value satisfies the associated condition. A request is transmitted to the plurality of computing devices to update the first access criterion to the second access criterion.

Blockchain smart contracts for digital asset access

According to an embodiment of the present disclosure, an event interface system, hereinafter the system, provides a record storage system and facilitates a proof of custody, proof of chain of custody and proof against tampering for a record by deploying a hash of the record on the blockchain and storing the record on an off-chain storage.

Blockchain proof of custody, proof against tampering, proof of chain of custody

A blockchain analytics system facilitates determination of parameters of blockchain objects for analytics. Examples of parameters of the blockchain object may include an identity of a participant, a role of a participant, a type of the blockchain object and the like. The system may store parameters of blockchain objects in the data repository. The system may use the determined parameters to generate a machine learning blockchain analytics model. The system may generate visualizations, detect patterns and/or for detecting anomalies based on the machine learning blockchain analytics model.

Blockchain analytics

The disclosed technology is generally directed to smart contract technology. In one example of the technology, responsive to a smart contract subscription request from a requestor to a first smart contract, a registry entry is added to a first smart contract registry such that the added registry entry includes requestor information associated with the requestor, and subscription information associated with at least one exposed interface of the first smart contract. Responsive to a change occurring that is associated with at least one exposed interface of the first smart contract, based on the registry, any subscribers to the first smart contract that have a subscription to which the change pertains are determined. Responsive to determining subscribers to the first smart contract that have a subscription to which the change pertains, the determined subscribers are caused to be notified of the change.

Subscription to dependencies in smart contracts

An Internet of Things (IoT) blockchain interface system facilitates receiving and deploying events from an IoT gateway to a blockchain using the event stack. The system also provides an interface between events that may affect objects on the blockchain from IoT sensors. The system also serves to authenticate IoT events such as sensor data.

Internet of things blockchain interface

An event interface system facilitates the creation of a blockchain object and deployment of the blockchain object on a blockchain. The system also provides an interface between events that may affect the blockchain object and the blockchain object stored on the blockchain. Additionally, the system can monitor a state of the blockchain object and control interactions with the blockchain object and updates to the blockchain object according to the determined state.

Blockchain object interface

An event interface system facilitates the creation and deployment of a first blockchain object and a second blockchain object on a first blockchain and a second blockchain respectively. The system also provides an interface between the first blockchain object and the second blockchain object via the event hub. Additionally, the system can allow interaction between blockchain objects on a private blockchain and a participant on the system.

Blockchain object deployment and synchronization across blockchains

Technologies are described herein for routing a service request to an appropriate web service. A first service request is routed from a first web service to a second web service. Routing factors associated with the second web service are monitored. A determination is made as to whether the routing factors indicate that the second web service is no longer appropriate for handling service requests. If the routing factors indicate that the first web service is no longer appropriate for handling service requests, then a second service request is routed from the first web service to a third web service. The first web service, the second web service, and the third web service are included in a composite service.

Optimized consumption of third-party web services in a composite service

Technologies are described herein for providing a monitoring service in a cloud-based computing environment. A request is received from a user to subscribe to the monitoring service. The monitor workflow may correspond to the monitoring service. A first call to a finder application is executed over a communications network to retrieve data points according to the monitor workflow. A second call to an analyzer application is executed over the communications network to identify a relevant data point in the data points. A third call to a notifier application is executed over the communications network to notify the user of the relevant data point.

Providing a monitoring service in a cloud-based computing environment

Technologies are described herein for rerouting a service request between service endpoints. The service request is received, at a first web service, from a second web service. The first web service and the second web service may be components of a composite service. The service request is routed to an initial service endpoint configured to respond to the service request according to a service level agreement between the first web service and the second web service. Service criteria associated with the initial service endpoint are monitored. A determination is made as to whether the service criteria meet a performance threshold specified by the service level agreement. If the service criteria do not meet the performance threshold specified by the service level agreement, then the service request is rerouted from the initial service endpoint to an alternate service endpoint.
