Alongside virtual money, blockchain has become the focus of interest in the technology news in recent years. Blockchain offers a decentralized mechanism for collecting immutable traces and allows, for example, the construction of alternative financial systems, without central banks, or autonomous organizations based on smart contracts; here Bitcoin and Ethereum, with their virtual currencies, bitcoin and ether, stand out.
