A Block is the fundamental unit of the Kadena blockchain. Each block bundles a verified set of transactions and metadata that secure and extend the chain. Blocks are linked together cryptographically — each one referencing its parent — forming the immutable and tamper-evident chain structure. This type exposes all the core properties of a block, including consensus data (like difficulty, nonce, and proof of work), network metadata (like chain ID and epoch), and relations to transactions, events, and neighboring blocks.

id
ID!,non-null

Globally unique identifier for this block node.

hash
String!,non-null

The cryptographic hash of the block. This serves as its unique identifier within the blockchain.

chainId
BigInt!,non-null

The specific chain where this block was mined. Kadena is a multi-chain system, and each block belongs to exactly one chain.

creationTime
DateTime!,non-null

The timestamp when this block was created and added to the chain.

difficulty
BigInt!,non-null

The network difficulty at the time the block was mined. Higher difficulty reflects the amount of computational work required to produce a valid block.

epoch
DateTime!,non-null

The epoch timestamp marking when the difficulty was last adjusted. Kadena targets ~30 seconds per block, and the difficulty is recalibrated periodically to maintain that target.

flags
Decimal!,non-null

Consensus flags used internally by the protocol.

height
BigInt!,non-null

The height (block number) of this block within its chain. The genesis block is height 0, and each subsequent block increments by 1.

nonce
Decimal!,non-null

A nonce value used in the proof-of-work process. Miners vary this value to discover a hash below the target threshold.

payloadHash
String!,non-null

The hash of the payload data contained within the block. This ensures the integrity of the transactions and other included data.

weight
String!,non-null

The cumulative weight of the chain up to and including this block. Weight increases with each mined block and helps determine the canonical chain.

target
String!,non-null

The target hash threshold that the block’s proof-of-work hash must fall below. This value adjusts with difficulty to regulate block production time.

coinbase
String!,non-null

The coinbase transaction data. This transaction rewards the miner and may include information about block rewards or other protocol-defined payouts.

neighbors

The neighboring blocks that reference this block as a parent. These neighbors are essential in Kadena’s braided multi-chain architecture.

powHash
String!,non-null

The proof-of-work hash of the block. This is the result of hashing the block header with the nonce and must satisfy the target condition.

canonical
Boolean!,non-null

Indicates whether this block is part of the canonical chain. Non-canonical blocks may occur during temporary forks or reorganizations.

parent

The parent block directly preceding this one in the chain. Together with the hash, this forms the cryptographic link that secures the chain.

totalGasUsedInKda
Decimal!,non-null

The total amount of gas used by all transactions in this block, expressed in KDA.

events

Paginated list of events emitted by transactions within this block.

afterbeforefirstlast
minerAccount

The account that mined this block and received the coinbase reward.

transactions

Paginated list of transactions included in this block.

afterbeforefirstlast

Implements interfaces

Node

A globally identifiable object in the GraphQL schema.

All core entities in this API implement the Node interface, which guarantees that they have a unique id field, enabling consistent caching, pagination, and reference resolution across the API.
