What has changed in block structure ?

What is the primary breaking change of block structure?

[sczembor]

Block structure:

The block structure will change with the condor release, however the historical blocks will still keep the old structure so it is important for all the parsers to support both the formats.

Pre-Condor (1.5.6):

block
├── hash
├── header
│   ├── parent_hash
│   ├── state_root_hash
│   ├── body_hash
│   ├── random_bit
│   ├── accumulated_seed
│   ├── era_end 
│   ├── timestamp
│   ├── era_id
│   ├── height
│   └── protocol_version
├── body
└── proofs

Post-Condor (2.0.0):

block_with_signatures
├── block (Version2)
│   ├── hash
│   ├── header
│   │    ├── parent_hash
│   │    ├── state_root_hash
│   │    ├── body_hash
│   │    ├── random_bit
│   │    ├── accumulated_seed
│   │    ├── era_end 
│   │    ├── timestamp
│   │    ├── era_id
│   │    ├── height
│   │    ├── protocol_version
│   │    ├── current_gas_price <-- NEW
│   │    ├── last_switch_block_hash <-- NEW
│   │    └── proposer <-- Moved from body
│   └── body
└── proofs

Key Changes:

• Versioning:

  • Introduction of explicit block structure versioning (Version2).
  • Pre Condor blocks are marked as Version1.

• Header:

  • New field: current_gas_price
  • New field: last_switch_block_hash
  • Moved Field: proposer moved from body.

• Body:

  • Now includes transactions and reward details rather than deploy_hashes

• Proofs:

  • Moved to top level (under block_with_signatures).
