Chunk Structure

Definition

Chunk of a Block is a part of a Block from a Shard. The collection of Chunks of the Block forms the NEAR Protocol Block

Chunk contains all the structures that make the Block:

• Transactions
• Receipts
• ChunkHeader

IndexerChunkView

Rust

pub struct ChunkView {
    pub author: AccountId,
    pub header: ChunkHeaderView,
    pub transactions: Vec<IndexerTransactionWithOutcome>,
    pub receipts: Vec<ReceiptView>,
}

TypeScript

export interface Chunk {
  author: string;
  header: ChunkHeader;
  transactions: IndexerTransactionWithOutcome[];
  receipts: Receipt[],
}

ChunkHeaderView

value

pub struct ChunkHeaderView {
    pub chunk_hash: CryptoHash,
    pub prev_block_hash: CryptoHash,
    pub outcome_root: CryptoHash,
    pub prev_state_root: StateRoot,
    pub encoded_merkle_root: CryptoHash,

    pub balance_burnt: Balance,
    pub outgoing_receipts_root: CryptoHash,
    pub tx_root: CryptoHash,
    pub validator_proposals: Vec<ValidatorStakeView>,
