Struct grin_chain::types::Tip

pub struct Tip {
    pub height: u64,
    pub last_block_h: Hash,
    pub prev_block_h: Hash,
    pub total_difficulty: Difficulty,
}

The tip of a fork. A handle to the fork ancestry from its leaf in the blockchain tree. References the max height and the latest and previous blocks for convenience and the total difficulty.

Fields

height: u64

Height of the tip (max height of the fork)

last_block_h: Hash

Last block pushed to the fork

prev_block_h: Hash

Previous block

total_difficulty: Difficulty

Total difficulty accumulated on that fork

Methods

impl Tip

pub fn from_header(header: &BlockHeader) -> Tip

Creates a new tip based on provided header.

pub fn hash(&self) -> Hash

Really easy to accidentally call hash() on a tip (thinking its a header). So lets make hash() do the right thing here.
