* change gas cost for contract creating txs * invalidate signature with s value greater than secp256k1 N / 2 * OOG contract creation if not enough gas to store code * new difficulty adjustment algorithm * new DELEGATECALL op code
* Removed some strange code that didn't apply state reverting properly * Refactored code setting from vm & state transition to the executioner * Updated tests
Assuming the following scenario where a miner has 15% of all hashing power and the ability to exert a moderate control over the network to the point where if the attacker sees a message A, it can't stop A from propagating, but what it **can** do is send a message B and ensure that most nodes see B before A. The attacker can then selfish mine and augment selfish mining strategy by giving his own blocks an advantage. This change makes the time at which a block is received less relevant and so the level of control an attacker has over the network no longer makes a difference. This change changes the current td algorithm `B_td > C_td` to the new algorithm `B_td > C_td || B_td == C_td && rnd < 0.5`.
