- [ ] #13897
- [x] Merge block-node `hedera-protobufs` [branch](https://github.com/hashgraph/hedera-protobufs/tree/continue-block-node) into main

### Writing Block To A File
- [ ] https://github.com/hashgraph/hedera-services/issues/13921
- [x] Implement a basic block-writing facility using the given output types (StateChange, transaction outputs by service, etc.) In other words, create `BlockStreamManager`

- [ ] https://github.com/hashgraph/hedera-services/issues/14438
- [ ] https://github.com/hashgraph/hedera-services/issues/14249
- [x] Attach StateChanges to pending stream builders in Savepoint commit
- [ ] https://github.com/hashgraph/hedera-services/issues/14247
- [ ] https://github.com/hashgraph/hedera-services/issues/14354
- [x] Write EventMetadata BlockItem's to the block stream
- [ ] https://github.com/hashgraph/hedera-services/issues/14668
- [ ] https://github.com/hashgraph/hedera-services/issues/14919

### State Changes
- [ ] https://github.com/hashgraph/hedera-services/issues/14138
- [x] Create a basic sequence diagram that describes the flow of state changes for a single user transaction
- [x] Write a mock implementation for defined state changes API (placeholder for more tickets)
- [ ] https://github.com/hashgraph/hedera-services/issues/14506
- [x] Determine areas where state is commited outside of the stack and try to use the stack.

### Testing And Verification
- [x] Use class from #14438 to verify block items

- [ ] https://github.com/hashgraph/hedera-services/issues/14963
- [ ] https://github.com/hashgraph/hedera-services/issues/14997
- [x] Create translators for pending airdrop transactions (when possible)

### Platform Dependencies
- [x] API for StateChanges
- [x] Event metadata
- [x] State Proof data needed

### Validators
- [ ] https://github.com/hashgraph/hedera-services/issues/14415
- [x] Transfer List, Token Transfer list, etc.
- [x] Validator to validate block metadata and hash chain
