The concept is enabling a blockchain-based system that could record changes to the conditions affecting and captured by sensors (i.e., smart objects) in a network and instrumentalize network relationships and the data that the network generates in order to exercise control over those nodes.

While working with Low-Power and Lossy Networks (LLNs), “routers and their interconnections are constrained” in terms of their “processing power, memory, and/or energy (battery), and their interconnections are characterized by, illustratively, high loss rates, low data rates, and/or instability.”

Additionally, “changing environmental conditions may also affect device communications.” As such, a system that enhances communications between these sensors and another device in the network could expand the number of practical LLN use cases.

In one embodiment, a device in a network receives a network registration request from a particular node. The device causes performance of a validation of the information about the particular node via comparison of the information about the particular node to a distributed block chain that includes information regarding the particular node and one or more other nodes.
 

About Cisco application

The application also lists “the smart grid, smart cities, and building and industrial automation” among the types of LLNs that might operate more efficiently with the integration of the invention.

The device causes an update to the block chain based on the information about the particular node and the validation of the information about the particular node. The device uses the updated block chain to control behavior of the particular node and the one or more other nodes.
 

About Cisco application

The smart objects/sensors that could, at least partially, comprise these networks include “lights, appliances, vehicles, HVAC (heating, ventilating, and air-conditioning), windows and window shades and blinds, doors, locks,” as well as actuators – automated devices that can, for instance, start an engine.

DFINITY to Postpone Internet Computer Launch

The project is currently assessing the time frame for the completion of the MVP

The blockchain project Dfinity reported in its blog postponing the launch of its main product.

Previously, Dfinity chief scientist Dominic Williams said that his company intends to create an “Internet computer that will become cloud 3.0”, compete with Google Cloud and Microsoft Azure, and also change the face of the blockchain industry.

According to him, the project team is developing a technology that has 150 higher performance than Ethereum blockchain and 900 times - Bitcoin. In essence, the project creates a “giant Internet computer”, whose work will be supported not by one company, but by all participants of the Dfinity protocol.

Initially, the release of a minimum viable product (MVP) was planned for the first quarter of 2019. However, according to company representatives, working on a trimmed version may slow down progress in creating a complete product.

The project is currently assessing the time frame for the completion of the MVP. Also, noted in Dfinity, before the end of the first quarter a new set of development tools (SDK) will be released, which will shed light on the future plans of the company.

In August, the Dfinity Foundation attracted $ 102 million of investments in the framework of a closed tokensale. Prior to this, at the beginning of the year, the Dfinity Foundation raised $ 61 million from Andreessen Horowitz and Polychain Capital.
