[−][src]Struct grin_core::core::compact_block::CompactBlock

pub struct CompactBlock {
    pub header: BlockHeader,
    pub nonce: u64,
    // some fields omitted
}

Compact representation of a full block. Each input/output/kernel is represented as a short_id. A node is reasonably likely to have already seen all tx data (tx broadcast before block) and can go request missing tx data from peers if necessary to hydrate a compact block into a full block.

Fields

The header with metadata and commitments to the rest of the data

Nonce for connection specific short_ids

Methods

impl CompactBlock
[src]

Get kern_ids

Get full (coinbase) kernels

Get full (coinbase) outputs

Trait Implementations

impl Writeable for CompactBlock
[src]

Implementation of Writeable for a compact block, defines how to write the block to a binary writer. Differentiates between writing the block for the purpose of full serialization and the one of just extracting a hash.

impl Readable for CompactBlock
[src]

Implementation of Readable for a compact block, defines how to read a compact block from a binary stream.

impl From<Block> for CompactBlock

impl<W> Hashed for W where
    W: Writeable, 
[src]

impl<H> ShortIdentifiable for H where
    H: Hashed, 
[src]

Generate a short_id via the following -

  • extract k0/k1 from block_hash hashed with the nonce (first two u64 values) * initialize a siphasher24 with k0/k1
    • self.hash() passing in the siphasher24 instance
    • drop the 2 most significant bytes (to return a 6 byte short_id)
