PoolVotingThresholds

class cometa.protocol_params.pool_voting_thresholds.PoolVotingThresholds(ptr)[source]

Bases: object

Voting thresholds for stake pool operators (SPOs) in governance actions.

Different governance actions have different ratification requirements. These thresholds specify the percentage of stake held by all stake pools that must be met by the SPOs who vote Yes for approval.

__init__(ptr)[source]

Return type:: None

__enter__()[source]

Return type:: PoolVotingThresholds

__exit__(exc_type, exc_val, exc_tb)[source]

Return type:: None

__repr__()[source]

Return repr(self).

Return type:: str

classmethod new(motion_no_confidence, committee_normal, committee_no_confidence, hard_fork_initiation, security_relevant_param)[source]

Creates a new PoolVotingThresholds instance.

Parameters:

motion_no_confidence (UnitInterval) – Threshold for motion of no-confidence.
committee_normal (UnitInterval) – Threshold for electing committee in confidence state.
committee_no_confidence (UnitInterval) – Threshold for electing committee in no-confidence state.
hard_fork_initiation (UnitInterval) – Threshold for hard fork initiation.
security_relevant_param (UnitInterval) – Threshold for security-relevant parameter changes.

Returns:

A new PoolVotingThresholds instance.

Raises:

CardanoError – If creation fails.

Return type:

PoolVotingThresholds

classmethod from_cbor(reader)[source]

Deserializes PoolVotingThresholds from CBOR data.

Parameters:: reader (CborReader) – A CborReader positioned at the thresholds data.
Returns:: A new PoolVotingThresholds deserialized from the CBOR data.
Raises:: CardanoError – If deserialization fails.
Return type:: PoolVotingThresholds

to_cbor(writer)[source]

Serializes the thresholds to CBOR format.

Parameters:: writer (CborWriter) – A CborWriter to write the serialized data to.
Raises:: CardanoError – If serialization fails.
Return type:: None

property motion_no_confidence: UnitInterval: Threshold for motion of no-confidence.

property committee_normal: UnitInterval: Threshold for electing committee when in confidence state.

property committee_no_confidence: UnitInterval: Threshold for electing committee when in no-confidence state.

property hard_fork_initiation: UnitInterval: Threshold for hard fork initiation.

property security_relevant_param: UnitInterval: Threshold for security-relevant parameter changes.

to_cip116_json(writer)[source]

Serializes this pool voting thresholds to CIP-116 compliant JSON.

Parameters:: writer (JsonWriter) – The JsonWriter to write the JSON to.
Raises:: CardanoError – If serialization fails.
Return type:: None
