In one of his interviews Sergey Nemesh, a CTO of Inn4science, said:
"In my opinion, top companies are those that make blockchain and cryptocurrencies, including cryptocurrency wallet development and other infrastructure elements development, clear and user-friendly for millions of users around the globe, making it a part of their daily life and enhancing the whole Blockchain technology. I would single out the following companies: Ethereum, Bitfury, IBM, EOS.
Ethereum being a base of hundreds of other systems providing smart-contracts which is already transforming the world of business.
Bitfury which are developing microlights to improve transaction speed as well as frameworks for blockchain development.
IBM which developed Hyperledger - a landmark project which will influence the whole enterprise sector.
I would say EOS has a great idea of providing the first software for decentralized apps. But the implementation has not happened yet. In case of realizing of their idea we can easily call EOS one of the top companies in Blockchain sector, which will influence the whole industry.
Do you have other good examples? I need them for my essay. Thanks all of you!
