@pedrouid I think there have been two separate lines of research for quite a few years, one focused on meta-txs and the "make it easier to pay for other accounts' txs" problem and the other on the "make smart contracts usable as first class user accounts" problem.
@pedrouid 我认为多年来有两条不同的研究方向，一个专注于元交易和“更容易支付其他账户的交易”问题，另一个关注“让智能合约可用作一流的用户帐户”问题。
