Abstract: A method and system of detecting a security threat within a network of connected devices that share a ledger of transactions between them under the form of exchanged blockchain messages (50). Enhanced blockchain messages are built by adding all forked chains (51) to the blockchain messages (50). Forked chains in such enhanced blockchains are then inspected to detect any anomaly. When an anomaly is detected in a forked chain, all transactions of the ledger in the forked chain (51) and the blockchain message (50) leading up to the network attack entry point are reviewed to identify the source of the security threat.

Abstract: Various embodiments relate to a method and apparatus for using blockchains as an integrity tracking tool for network elements, the method including the steps of receiving, by a blockchain network, a patch request from a patch initiator, validating, by the blockchain network, the patch request and writing the patch request on the blockchain, transmitting, by the blockchain network, the patch request to a network element, receiving, by the blockchain network, a patch report from the network element, and validating, by the blockchain network, the patch report and writing the patch report on the blockchain.

Abstract: A floating vessel comprising, in the orientation of use, a central longitudinal member (2) having a vertical height, and to each side of the longitudinal member an upper substantially laminar panel (3) connected to the longitudinal member and extending outwardly therefrom and a lower substantially laminar panel (4) connected to the longitudinal member at a distance below the upper panel and extending outwardly from the longitudinal member, wherein the outermost edges of the upper and lower panels are connected and the lower panel is larger in the outward direction than the upper panel such that the panels form a stable structure.
