Why Blockchain Is the Further Step of Technological Revolution?
Cloud technologies were the first move away from centralization. Companies had to find a way to store data and gain access to computation power via net with sufficient traffic capacity and security. Nonetheless, server rooms required maintenance, permanent guard, proper resources and continuous updates. But moving its servers to cloud companies enhanced scope of operations beyond the limits hardware set.
Today companies may establish offices almost everywhere and hire remote employees. Computers and smartphones are barely a bridge to the higher capacities located somewhere else.
Now blockchain takes up the torch. With distributed registry system the technology has given birth to computing nets of safe, invariable and democratic character. This may result in unhackable programs and web-services, transparent networks and higher system reliability.
Blockchains use miners for solving mathematical tasks and consensus. Mining industry members lease their computational power in the blockchain net for cryptocurrency as a reward. All together they form a net and check creation of new blocks. Groups of miners comprise a nodes system in the net that keep and process data.
Ethereum, one of the most popular crypto platforms today, allows for the developers to gain access to blockchain via Ethereum virtual machine (EVM). EVM offers development tools for creating decentralized applications (Dapps) using blockchain to dispose their internal processes.
Instead of application functioning on a single server, Dapps get split into partitions like torrent and start simultaneously. The programs make up a command registry that checks the code constantly. None of the computers has the complete app backend so it is impossible to hack or damage it.
Unlike cloud calculations decentralized blockchain is not limited with a server room. Cloud apps generally distribute activity among several nodes which is not a patch on thousands of nodes in the networks like Ethereum.
Cloud technologies have moved servers from university towns and centralized computational powers in other locations. Blockchain may disperse it throughout the globe.
This side of blockchain destroys public belief in cryptocurrencies having no value and being nothing but another bubble. In fact, cryptocurrency may function as smarter and safer barter system that improves Internet and applications. Using blockchain we can create Internet/Cloud 2.0 which enhances cyber security and facilitates progress as far as AI, IoT, etc. are concerned.
