#BinancePizza appeared in 2009 with Bitcoin and its blockchain, hundreds of other crypto-assets then developed, also known as Altcoins (a portmanteau combining two English words, "alt" meaning alternative and "). This word refers to all other cryptocurrencies, alternatives to Bitcoin, generally also using blockchain technology, but with different consensus algorithms, features, and more or less similar goals, less consuming of computing and energy resources, like Ethereum, or further increasing the privacy of transactions, etc.
