Validation logic

Block Validation (standalone)

• Validate the "transaction body"
  • Validate the total weight, including reward is lower than the consensus max weight
  • Validate the sorting of inputs, outputs and kernels by their hashes
  • Validate the block has been fully cut-through (no inputs matching an included output)
  • Batch verify all output range proofs (but only those that aren't in the validation cache yet)
  • Verify all kernel signatures against the excess and the message (fee+lock_time?)
• Verify no kernels have a future lock height
• Check that the reward plus fees "sums" correctly with the coinbase outputs commitments and kernels excess
• Verify the big "sum": all inputs plus reward+fee, all output commitments, all kernels plus the kernel excess from the header
