edge or fog computing coming on strong in 2020

What is this edge or fog computing trend ? 

Both edge and fog computing provide similar functionalities where smart devices or items or sensors push data and analytics to cloud platforms.

Fog computing and edge computing are effectively the same thing." 

 Both are concerned with leveraging the computing capabilities within a smaller simpler server / gateway or sensor hardware device and process and share data via a localized network to carry out computation tasks that would ordinarily have been carried out in the cloud. More advanced AI and data processing still are done on the cloud.   

Both technologies can help organizations reduce their reliance on cloud-based platforms to analyze data, provide intelligent automation and analysis.

The main difference between edge computing and fog computing comes down to where the processing of that data takes place.

Edge computing usually occurs directly on the devices to which the sensors are attached or a gateway device that is physically “close” to the sensors. 

Fog computing moves the edge computing activities to processors that are connected to the LAN or into the LAN hardware itself so they may be physically more distant from the sensors and actuators. Think NB-IoT or LoRa or mesh networks and those types of IoT technologies.

The blockchain ecosystem helps farmers receive fair prices and provides consumers with trustable and transparent data on product origins

HAITIAN FARMERS USE BLOCKCHAIN TO SECURE BETTER PRICES
UK-based startup Agriledger has created a blockchain system to help Haitian farmers sell their products at fair prices. The system fosters trust on both sides of the transaction, leading to better income for farmers and better goods for consumers.
The startup’s system offers farmers a number of services, and access to global markets and banks. Using blockchain technology, it provides registered farmers with a unique digital identification number, which makes the farmers key players in the supply chain, and gives them access to financial services, logistics, insurance and other services.  
The farmers can also tokenize their assets, making peer-to-peer trading easier and giving them further access to the commodities market. This digital system provides the farmers with several benefits; the data is inherently trustworthy, so the entire supply chain is more transparent and traceable, and it also simplifies record keeping, so it is easi…
