EVM結(jié)構(gòu).png

對(duì)于EVM虛擬機(jī)，覺(jué)得可以從兩方面進(jìn)行抽象，實(shí)現(xiàn)拓展；

1. VM層進(jìn)行抽象，從根本上來(lái)說(shuō)，EVM只對(duì)外暴漏了兩個(gè)方法調(diào)用Call、Create.

   type VM interface{
       Create(caller types.ContractRef, code []byte, gas uint64, val sdk.Int) (ret []byte, contractAddr sdk.AccAddress, gasLeft uint64, err error)
     
       Call(caller types.ContractRef, toAddr sdk.AccAddress, input []byte, gas uint64, val sdk.Int) (ret []byte, gasLeft uint64, err error)
   }
   

2. 解釋器層抽象，解釋器的功能比較單純，給定合約和輸入，得到輸出。

   type Interpreter interface {
       Run(contract *Contract, input []byte, static bool) ([]byte, error)
   }
