Blockchain technology is popular and gaining momentum. According to the consulting company Accenture, in 2018-2024 blockchain will spread to many types of assets, and by 2025 this technology will become a mass and integral part of global capital. While at the time the technology appeared, many doubted its promise, now even the largest companies are applying it to their operations. These include Microsoft, PayPal, Intuit, DISH Network and other giants. The experience of such companies showed and proved that blockchain technology can be used not only in the crypto world, but also in business. In what way? I suggest we talk about that.
