Consensus Related

• (empty -> value -> zero) write zero to storage even when it was empty previously
• charge CALL before deducting 1/64 gas
• charge CREATE gas after deducting 1/64 gas
• chunk fill cost Added CHUNK_FILL_COST #6983
• charge CREATE complete cost after the code is inserted before adding back 1/64 gas
• geth - correct account code is accessed - DELEGATE CALL
• eip-4762 changes from interop
• compress all the basic account values in the first chunk
• add witness after we confirm that we have enough gas to be charged - should be atomic by access events
• special handling for system calls
• block hash gas changes and warming things up
• add previous state root to the execution witness ( achieve complete stateless verification )

Other Changes

• start storing execution witness to the disk
• implement a pruning mechanism for these execution witness
• add a background task to execute blocks and store stateless trees (in memory) - we can always re-execute the blocks to regenerate this on startup. but then also consider about the perf degradation due to a lot of this in cach?
