## Simple Summary
Do not allow transactions for which `tx.sender` has any code deployed, i.e. `tx.sender` has `CODESIZE != 0`

## Specification
Any transaction where `tx.sender` has a `CODESIZE != 0` MUST be rejected as invalid.
Any transaction where `tx.sender` has a `CODEHASH != EMPTYCODEHASH` MUST be rejected as invalid.
With `EMPTYCODEHASH = 0xc5d2460186f7233c927e7db2dcc703c0e500b653ca82273b7bfad8045d85a470`.

The following check must be added to the state transition checks after checking that the nonce of the sender is correct.
```
// Make sure the sender is an EOA
Set cs to the CodeSize of the sender account
if cs is not 0 then
Set ch to the CodeHash of the sender account
if cs is not equal to EmptyCodeHash then
return ErrSenderNoEOA
end if
