The development of new protocols, improving the scalability of blockchains and creating more convenient and secure wallets – all this contributes to the popularization of cryptocurrencies and the expansion of their use. Special attention is paid to solutions aimed at reducing energy consumption during mining, which makes cryptocurrencies more environmentally friendly.
