## Week 9 , 10 and 11 - Updates

1. Implemented LogIndexSummary Structure according to [M0 milestone]()

- Implemented 256-byte serialization for LogIndexSummary
- Added createLogIndexSummary() and encodeLogIndexSummary()

2. Added Activation Logic

- Added function shouldUseLogIndex(blockNumber: uint64) to replace logsBloom once EIP 7745 is activated

3. Integrated logIndex in Block Header Integration (tx_packer.nim)

- logsBloom field is replaced with LogIndexSummary for post activation blocks

4. Block Processing Flow

- Updated process_block.nim to correctly validate LogIndexSummary vs traditional bloom

5. Created Test Suite for log_index functionality testing with edge cases

- Added test suites covering all basic functionality
- All tests passing with Activation logic, LogIndex operations, LogIndexSummary creation e.t.c

## Next

- Currently only unit tests for LogIndex are implemented,
need tests to verify complete block processing with tx_packer and process_block integration
- Hash Tree Root calculation needs to be updated for SSZ compliance
- Some structures are missing fields as per M0 spec, need to review them
- FilterMaps implementation is missing as per M0 spec

## Estimate

It should take 2 more weeks to complete above tasks to start testing with Kurtosis.
