Fields

epoch_core_reward_credits_for_distribution: FeatureVersion

daily_withdrawal_limit: FeatureVersion

deduct_fee_from_outputs_or_remaining_balance_of_inputs: FeatureVersion

compute_minimum_shielded_fee: FeatureVersion

shielded_extra_sighash_data: FeatureVersion

core_credit_pool_unlock_limit: OptionalFeatureVersion

The Core-anchored withdrawal limit: how much Core’s credit pool may still drop given its balance now and at the window start (SystemLimits::core_credit_pool_unlock_limit_percent and core_credit_pool_unlock_limit_floor). Exists from protocol version 14.

credit_pool_bundle_binding: OptionalFeatureVersion

The preimage the outputs-only bundles of the credit pool (Shield, ShieldFromIdentity, ShieldFromAssetLock) bind into their Orchard sighash. None on versions that predate the binding: they bind nothing, which is what every shipped verifier expects. Some(0): they bind kind tag (1) || owner (32).

The client builders and the consensus sites protocol version 14 selects read this one field through the same helpers, so a client building for a protocol version produces the preimage that version’s verifier rebuilds. validate_shielded_proof v0 and the ShieldFromAssetLock transform v0 rebuild an empty preimage without reading it; credit_pool_bundle_binding_should_agree_with_the_selected_shield_verifiers_at_every_protocol_version holds them and this field together.
