Struct template_distribution_sv2::SetNewPrevHash

pub struct SetNewPrevHash<'decoder> {
    pub template_id: u64,
    pub prev_hash: U256<'decoder>,

    pub n_bits: u32,
    pub target: U256<'decoder>,

SetNewPrevHash (Server -> Client)

Upon successful validation of a new best block, the server MUST immediately provide a SetNewPrevHash message. If a [NewWork](TODO link) message has previously been sent with the [future_job](TODO link) flag set, which is valid work based on the prev_hash contained in this message, the template_id field SHOULD be set to the job_id present in that NewTemplate message indicating the client MUST begin mining on that template as soon as possible. TODO: Define how many previous works the client has to track (2? 3?), and require that the server reference one of those in SetNewPrevHash.

Fields

template_id: u64

template_id referenced in a previous NewTemplate message.

prev_hash: U256<'decoder>

Previous block’s hash, as it must appear in the next block’s header.

header_timestamp: u32

The nTime field in the block header at which the client should start (usually current time). This is NOT the minimum valid nTime value.

n_bits: u32

Block header field.

target: U256<'decoder>

The maximum double-SHA256 hash value which would represent a valid block. Note that this may be lower than the target implied by nBits in several cases, including weak-block based block propagation.
