Activate EIP155 and EIP158, Byzantine HF

This should have made it into HF6 but now can be tested before merge and next release.

EIP155 replay protection, Chain ID: 61717561

Spurious Dragon, aka State-clearing, EIP 158/161, was released in Nov 2016. Spurious Dragon is aiming for Dapp developers as well as end users for limited categories of applications, and had a number of security enhancements.

With Byzantine HF:

  • Addition of ‘REVERT’ opcode, which permits error handling without consuming all gas (EIP 140)
  • Transaction receipts now include a status field to indicate success or failure EIP 658)
  • Elliptic curve addition and scalar multiplication on alt_bn128 (EIP 196) and pairing checks (EIP 197), permitting ZK-Snarks and other cryptographic mathemagic™
  • Support for big integer modular exponentiation (EIP 198), enabling RSA signature verification and other cryptographic applications
  • Support for variable length return values (EIP 211)
  • Addition of the ‘STATICCALL’ opcode, permitting non-state-changing calls to other contracts (EIP 214)
