Account?
1.一種有contract code
一般這種由EOA創(chuàng)建出來
contract account
address
address state
nonce ?balance
storage hash ?code hash
2.一種沒有
external owed account （EOA）
address
address state
nonce balance
transaction有三種
a: 轉(zhuǎn) Enter
b: 部署contract （create contact）
c: 呼叫contact 里特定的function （call contract）
EOA
幾個重要位置：
call
from：送出者
to：接收者
value：給多少
data：轉(zhuǎn)賬的備注?
（永久的留在鏈上）
create contact
from：發(fā)送者
to：留空沒有接收者婶肩，trancation 部署新的合約?
data：把你的bytecode 放進(jìn)來
value：送到contact 中可以給
call function
合約執(zhí)行
統(tǒng)一的opcode,opcode/storage價格固定
沒有隨機(jī)性opcode 不會出現(xiàn)0.1 + 0.9 = 9.999
