Account abstraction - EIP 86

[chriseth]

Implement ethereum/EIPs#86

TODO

• Transactions with signature (0, 0, 0) (ie. v = r = s = 0 0) are valid and msg.sender is set to uint120(-1) during execution.
• Accept those transactions if they are coming in from blocks, but do not forward such transactions if they are coming in not yet in a block.

Reminder: we need to disable incrementing the nonce of the sender in case of zero signature

Reminder: we need to change the way the addresses of new contracts are calculated.

Reminder: we need to add CREATE_P2SH instruction.

@pirapira yep I think I could do that next week.

What do we do with this?

[pirapira]

@chfast we leave it until there is a decision whether Constantinople includes this or not.

[pirapira]

@chfast since there is nothing to do currently, we can close this issue, I think.

Based on AllCoreDev ethereum/pm#52, the EIP-86 is probably not going to be accepted in this "big" variant.
