CBlock

Synopsis

Declared in <primitives/block.h>

class CBlock
    : public CBlockHeader

Name	Description
`CBlockHeader`	Nodes collect new transactions into a block, hash them into a hash tree, and scan through nonce values to make the block's hash satisfy proof-of-work requirements. When they solve the proof-of-work, they broadcast the block to everyone and the block is added to the block chain. The first transaction in the block is a special one that creates a new coin owned by the creator of the block.

Name	Description
`CBlock` [constructor]	Constructors
`GetBlockTime`	Returns the block creation time.
`GetHash`	Computes the block hash by hashing the serialized header.
`IsNull`	Returns true when the header has no proof-of-work target set.
`SetNull`	Resets the block to its null state, clearing transactions and cached flags.
`Time`	Returns the block time as a chrono time point.
`ToString`	Returns a human-readable description of the block.

Name
`Ser`
`Unser`

Name	Description
`fChecked`	Cached result of CheckBlock() for this block.
`hashMerkleRoot`	Merkle root of the transactions in the block.
`hashPrevBlock`	Hash of the previous block header in the chain.
`m_checked_merkle_root`	Cached result of the Merkle root check for this block.
`m_checked_witness_commitment`	Cached result of the witness commitment check for this block.
`nBits`	Compact representation of the proof-of-work difficulty target.
`nNonce`	Nonce varied during mining to satisfy the proof-of-work target.
`nTime`	Block creation time, as a Unix timestamp in seconds.
`nVersion`	Block version number, signaling supported consensus rules.
`vtx`	Transactions contained in the block, in order.

Name	Description
`BlockMerkleRoot`	Compute the Merkle root of the transactions in a block. *mutated is set to true if a duplicated subtree was found.
`BlockWitnessMerkleRoot`	Compute the Merkle root of the witness transactions in a block.
`CheckBlock`	Context-independent validity checks.
`CheckSignetBlockSolution`	Extract signature and check whether a block has a valid solution
`DecodeHexBlk`	Decode a hex-encoded serialized block.
`DecodeHexBlockHeader`	Decode a hex-encoded serialized block header.
`GetBlockProof`	Compute how much work a block header corresponds to.
`GetWitnessCommitmentIndex`	Compute at which vout of the block's coinbase transaction the witness commitment occurs, or -1 if not found
`IsBlockMutated`	Check if a block has been mutated (with respect to its merkle root and witness commitments).
`TransactionMerklePath`	Compute merkle path to the specified transaction
`node::AddMerkleRootAndCoinbase`	Insert the coinbase transaction and compute the merkle root of a block.
`node::RegenerateCommitments`	Update an old GenerateCoinbaseCommitment from CreateNewBlock after the block txs have changed
`node::UpdateTime`	Update a block header's time field and return the new time.
