Constant solana_program::clock::MAX_HASH_AGE_IN_SECONDS [−][src]
pub const MAX_HASH_AGE_IN_SECONDS: usize = 120;
Expand description
The time window of recent block hash values that the bank will track the signatures
of over. Once the bank discards a block hash, it will reject any transactions that use
that recent_blockhash
in a transaction. Lowering this value reduces memory consumption,
but requires clients to update its recent_blockhash
more frequently. Raising the value
lengthens the time a client must wait to be certain a missing transaction will
not be processed by the network.
