Ethereum é frequentemente descrito como o "computador mundial". Mas o que isso significa? Vamos começar com uma descrição focada na ciência da computação e depois tentar decifrá-la com uma análise mais prática dos recursos e das características da Ethereum, comparando-a com o Bitcoin e outras plataformas descentralizadas de troca de informações (ou blockchains, para ser mais preciso).
Do ponto de vista da ciência da computação, a Ethereum é uma máquina de estado determinística, mas praticamente ilimitada, que consiste em um estado singleton acessível globalmente e uma máquina virtual que aplica alterações a esse estado.
De uma perspectiva mais prática, a Ethereum é uma infraestrutura de computação de código aberto e globalmente descentralizada que executa programas chamados contratos inteligentes. Ela usa um blockchain para sincronizar e armazenar as alterações de estado do sistema, juntamente com uma criptomoeda chamada ether para medir e restringir os custos dos recursos de execução.
A plataforma Ethereum permite que os desenvolvedores criem aplicativos descentralizados avançados com funções econômicas integradas. Ela oferece alta disponibilidade, capacidade de auditoria, transparência e neutralidade, ao mesmo tempo em que reduz ou elimina a censura e reduz determinados riscos de contraparte.
