Struct Proof

#[repr(C)]
pub struct Proof {
    pub authority: Pubkey,
    pub balance: u64,
    pub challenge: [u8; 32],
    pub last_hash: [u8; 32],
    pub last_hash_at: i64,
    pub last_claim_at: i64,
    pub miner: Pubkey,
    pub total_hashes: u64,
    pub total_rewards: u64,
}

Proof accounts track a miner’s current hash, claimable rewards, and lifetime stats. Every miner is allowed one proof account which is required by the program to mine or claim rewards.

Fields

authority: Pubkey

The signer authorized to use this proof.

balance: u64

The quantity of tokens this miner has staked or earned.

challenge: [u8; 32]

The current mining challenge.

last_hash: [u8; 32]

The last hash the miner provided.

last_hash_at: i64

Timestamp of the last time this account provided a hash.

last_claim_at: i64

Timestamp of the last claim.

miner: Pubkey

The keypair which has permission to submit hashes for mining.

total_hashes: u64

The total lifetime hashes provided by this miner.

total_rewards: u64

The total lifetime rewards distributed to this miner.

Trait Implementations

impl AccountValidation for Proof

fn assert<F>(&self, condition: F) -> Result<&Self, ProgramError>

where F: Fn(&Self) -> bool,

fn assert_err<F>( &self, condition: F, err: ProgramError, ) -> Result<&Self, ProgramError>

where F: Fn(&Self) -> bool,

fn assert_msg<F>(&self, condition: F, msg: &str) -> Result<&Self, ProgramError>

where F: Fn(&Self) -> bool,

fn assert_mut<F>(&mut self, condition: F) -> Result<&mut Self, ProgramError>

where F: Fn(&Self) -> bool,

fn assert_mut_err<F>( &mut self, condition: F, err: ProgramError, ) -> Result<&mut Self, ProgramError>

where F: Fn(&Self) -> bool,

fn assert_mut_msg<F>( &mut self, condition: F, msg: &str, ) -> Result<&mut Self, ProgramError>

impl Clone for Proof

fn clone(&self) -> Proof

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Proof

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Discriminator for Proof

fn discriminator() -> u8

impl PartialEq for Proof

fn eq(&self, other: &Proof) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Zeroable for Proof

fn zeroed() -> Self

Calls zeroed.

impl Copy for Proof

impl Pod for Proof

impl StructuralPartialEq for Proof
