[gumb0]

Possible EIPs

• EIP-663: Unlimited SWAP and DUP instructions
  • implementation in evmone Implement EIP-663 variant C evmone#98
• EIP-1057: ProgPoW, a Programmatic Proof-of-Work
  • Supported in ethash library, but PoW engine switching logic not implemented yet.
• EIP-1380: Reduced gas cost for call to self
  • LegacyVM Implement eip1380 (call-to-self) in LegacyVM #5752

• EIP-1962: EC arithmetic and pairings with runtime definitions
• EIP-1985: Sane limits for certain EVM parameters
  • Not sure if anything needs to be done here
• EIP-2045: Particle gas costs for EVM opcodes
  • implementation in evmone Introduce particle gas costs evmone#101
• EIP-2046: Reduced gas cost for static calls made to precompiles
  • LegacyVM Implement EIP-2046 Reduced gas cost for static calls made to precompiles in LegacyVM #5699

Maintenance stuff

• Ropsten config update
