Vitalik: A abstração da conta ainda está incompleta no momento, então você precisa ter cuidado com a dependência excessiva de intermediários

Ethereum co-founder Vitalik Buterin said on account abstraction, “We still don’t have a complete account abstraction. It is impossible to trade from an account without using ECDSA verification unless it is passed (intermediary dependency is harmful to privacy and censorship resistance and is often harmful to the right to do things without permission). For example, if your account does not rely on an intermediary for transactions, you cannot achieve quantum security; you cannot create a Protocolo de privacidade que não depende de um ecossistema de transmissão pública (frágil).
