Abstract: Described are examples for detecting possible failure in network nodes by monitoring, by a monitoring application, a data throughput for at least one of data sent or received at a network node over a time period, detecting a possible failure of the network node based on comparing the data throughput to an average data throughput for the network node measured over one or more historical time periods of a similar duration as the time period, and/or reporting the possible failure of the network node.

Abstract: In a hosted computing environment a web server receives a document history graph. The web server performs a hash function, providing the document history graph as input to the hash function, the hash function providing a hash value as output. A blockchain services interface in the hosted computing environment generates a blockchain block that includes the hash value in a block payload hash field and the document history graph in a block payload field in the blockchain block. A blockchain consensus manager proposes adding the blockchain block to a private blockchain and receives an indication of consensus A block validator adds the blockchain block to the private blockchain responsive to consensus.

Abstract: In a hosted computing environment having at least one processor and a memory therein, a web server in the hosted computing environment receives a document history graph. The web server performs a hash function, providing the document history graph as input to the hash function, the hash function providing a hash value as output. A blockchain services interface in the hosted computing environment generates a blockchain block that includes the hash value in a block payload hash field and the document history graph in a block payload field in the blockchain block. A blockchain consensus manager in the hosted computing environment proposes adding the blockchain block to a private blockchain. The blockchain consensus manager receives an indication of consensus among authorized blockchain nodes in the private blockchain to add the blockchain block to the private blockchain.
