Juniper Research, a market research organization, points out that the smart home market in the next five years is expected to be led by four major manufacturers. 
Juniper Research first explained that what the market now calls “intelligent households†has a wide range of systems, ranging from hardware devices to application services, including audio and video entertainment, monitoring devices, automation equipment, health care and smart appliances. Products, among which the most promising and fastest-growing areas in the next five years are smart home appliances and home automation equipment, and this growth is attributable to manufacturers such as GE, Samsung, and Bosch adding to their products. The smart connection function.
So who will be the big winner in this war situation in this $100 billion market? Juniper Research named Amazon, Samsung, Google's Alphabet, and Apple as the four big families of smart households. In addition, it includes the success of business models, product development, innovation levels, and the breadth of cooperation between different industries. The parameters make the ranking among the above four companies.
Juniper Research believes that these four big companies will gradually develop their own ecosystems, driven by cloud services and their numerous devices, and will become the key players in the smart home market. Among them, the agency will see Amazon as the leader. The reason for the sheep is that it has successfully used its development in the field of e-commerce. By complementing with a large number of partners in the market, including application developers, hardware vendors, and even service providers, the company managed to maximize the value of its voice service, Alexa, thus driving Amazon's ecosystem. Amazon used its own cloud platform and technology to allow Echo and Alexa to differentiate themselves when faced with other competitors.
Although Amazon Echo, which was first introduced in 2014 by Amazon, has achieved great success in the market and has been hailed as the most successful smart home device today, Amazon still has to be careful with other rivals, such as Google’s Nest Protect smart smoke detection. Devices, or Google Home launched by Alphabet, and Apple's HomeKit platform, etc., will all benefit from smart homes' expectations of consumers in 2017.

The word mining originates in the context of the gold analogy for cryptocurrencies. Gold or precious metals are scarce, so are digital tokens, and the only way to increase the total volume in a proof-of-work system is through mining. In proof-of-work Ethereum, the only mode of issuance was via mining. Unlike gold or precious metals however, Ethereum mining was also the way to secure the network by creating, verifying, publishing and propagating blocks in the blockchain.
