pub const MAX_UNPAID_ALLOWED_PROPOSERS: u64 = 3;Expand description
The number of allowed proposers a transaction may name without paying for amplification.
Beyond this, SIP-45 caps the proposer set at gas_price / reference_gas_price.
Naming several proposers is also what keeps a transaction submittable when some of them are offline, so this is a floor as much as it is an allowance.
