Expand description

A struct responsible for verifying block header.

Implementations§

source§

impl<Block, Client> HeaderVerifier<Block, Client>

source

pub fn new(client: Arc<Client>, chain_params: ChainParams) -> Self

Constructs a new instance of HeaderVerifier.

source§

impl<Block, Client> HeaderVerifier<Block, Client>
where Block: BlockT, Client: HeaderBackend<Block> + AuxStore,

source

pub fn verify(&self, header: &BitcoinHeader) -> Result<u32, Error>

Validates the header and returns the block time, which is used for verifying the finality of transactions.

The validation process includes:

  • Checking the proof of work.
  • Validating the block’s timestamp:
    • The time must not be more than 2 hours in the future.
    • The time must be greater than the median time of the last 11 blocks.

source

pub fn has_valid_proof_of_work(&self, header: &BitcoinHeader) -> bool
