Odaily News Ethereum co-founder Vitalik Buterin said in a speech at the cryptocurrency conference BUIDL Asia in Seoul, South Korea on Wednesday that account abstraction is a way to provide security and convenience for blockchain developers and users. According to Vitalik, modern account abstractions include additional features not currently supported by Ethereum that could improve security and convenience. Security goals include allowing users to change and revoke private keys and better means of account recovery, while convenience goals include the ability for users to pay gas fees in ERC-20 and payment automation.
