<a id="packages.valory.skills.abstract_round_abci.base.AbciAppDB"></a>

## AbciAppDB Objects

```python
class AbciAppDB()
```

Class to represent all data replicated across agents.

This class stores all the data in self._data. Every entry on this dict represents an optional "period" within your app execution.
The concept of period is user-defined, so it might be something like a sequence of rounds that together conform a logical cycle of
its execution, or it might have no sense at all (thus its optionality) and therefore only period 0 will be used.

Every "period" entry stores a dict where every key is a saved parameter and its corresponding value a list containing the history
of the parameter values. For instance, for period 0:

0: {"parameter_name": [parameter_history]}

A complete database could look like this:

data = {
    0: {
        "participants":
            [
                {"participant_a", "participant_b", "participant_c", "participant_d"},
                {"participant_a", "participant_b", "participant_c"},
                {"participant_a", "participant_b", "participant_c", "participant_d"},
            ]
        },
        "other_parameter": [0, 2, 8]
    },
    1: {
        "participants":
            [
                {"participant_a", "participant_c", "participant_d"},
                {"participant_a", "participant_b", "participant_c", "participant_d"},
                {"participant_a", "participant_b", "participant_c"},
                {"participant_a", "participant_b", "participant_d"},
                {"participant_a", "participant_b", "participant_c", "participant_d"},
            ],
        "other_parameter": [3, 19, 10, 32, 6]
    },
    2: ...
}

__Adding and removing data from the current period__

--------------------------------------------------
To update the current period entry, just call update() on the class. The new values will be appended to the current list for each updated parameter.

To clean up old data from the current period entry, call cleanup_current_histories(cleanup_history_depth_current), where cleanup_history_depth_current
is the amount of data that you want to keep after the cleanup. The newest cleanup_history_depth_current values will be kept for each parameter in the DB.

__Creating and removing old periods__

-----------------------------------
To create a new period entry, call create() on the class. The new values will be stored in a new list for each updated parameter.

To remove old periods, call cleanup(cleanup_history_depth, [cleanup_history_depth_current]), where cleanup_history_depth is the amount of periods
that you want to keep after the cleanup. The newest cleanup_history_depth periods will be kept. If you also specify cleanup_history_depth_current,
cleanup_current_histories will be also called (see previous point).

The parameters cleanup_history_depth and cleanup_history_depth_current can also be configured in skill.yaml so they are used automatically
when the cleanup method is called from AbciApp.cleanup().

__Memory warning__

-----------------------------------
The database is implemented in such a way to avoid indirect modification of its contents.
It copies all the mutable data structures*, which means that it consumes more memory than expected.
This is necessary because otherwise it would risk chance of modification from the behaviour side,
which is a safety concern.

The effect of this on the memory usage should not be a big concern, because:

    1. The synchronized data of the agents are not intended to store large amount of data.
     IPFS should be used in such cases, and only the hash should be synchronized in the db.
    2. The data are automatically wiped after a predefined `cleanup_history` depth as described above.
    3. The retrieved data are only meant to be used for a short amount of time,
     e.g., to perform a decision on a behaviour, which means that the gc will collect them before they are noticed.

* the in-built `copy` module is used, which automatically detects if an item is immutable and skips copying it.
For more information take a look at the `_deepcopy_atomic` method and its usage:
https://github.com/python/cpython/blob/3.10/Lib/copy.py#L182-L183

<a id="packages.valory.skills.abstract_round_abci.base.AbstractRound"></a>

## AbstractRound Objects

```python
class AbstractRound(Generic[EventType], ABC, metaclass=_MetaAbstractRound)
```

This class represents an abstract round.

A round is a state of the FSM App execution. It usually involves
interactions between participants in the FSM App,
although this is not enforced at this level of abstraction.

Concrete classes must set:
- synchronized_data_class: the data class associated with this round;
- payload_class: the payload type that is allowed for this round;

Optionally, round_id can be defined, although it is recommended to use the autogenerated id.

<a id="packages.valory.skills.abstract_round_abci.base.AbstractRound.__init__"></a>

#### `__`init`__`

```python
def __init__(
    synchronized_data: BaseSynchronizedData,
    context: SkillContext,
    previous_round_payload_class: Optional[Type[BaseTxPayload]] = None
) -> None
```

Initialize the round.

<a id="packages.valory.skills.abstract_round_abci.base.AbstractRound.auto_round_id"></a>

#### auto`_`round`_`id

```python
@classmethod
def auto_round_id(cls) -> str
```

Get round id automatically.

This method returns the auto generated id from the class name if the
class variable behaviour_id is not set on the child class.
Otherwise, it returns the class variable behaviour_id.

<a id="packages.valory.skills.abstract_round_abci.base.AbstractRound.round_id"></a>

#### round`_`id

```python
@property
def round_id() -> str
```

<a id="packages.valory.skills.abstract_round_abci.base.AbstractRound.check_transaction"></a>

#### check`_`transaction

```python
def check_transaction(transaction: Transaction) -> None
```

Check transaction against the current state.

**Arguments**:

- `transaction`: the transaction

<a id="packages.valory.skills.abstract_round_abci.base.AbstractRound.process_transaction"></a>

#### process`_`transaction

```python
def process_transaction(transaction: Transaction) -> None
```

Process a transaction.

By convention, the payload handler should be a method
of the class that is named '{payload_name}'.

**Arguments**:

- `transaction`: the transaction.

<a id="packages.valory.skills.abstract_round_abci.base.AbstractRound.end_block"></a>

#### end`_`block

```python
@abstractmethod
def end_block() -> Optional[Tuple[BaseSynchronizedData, Enum]]
```

Process the end of the block.

The role of this method is check whether the round
is considered ended.

If the round is ended, the return value is
 - the final result of the round.
 - the event that triggers a transition. If None, the period
    in which the round was executed is considered ended.

This is done after each block because we consider the consensus engine's
block, and not the transaction, as the smallest unit
on which the consensus is reached; in other words,
each read operation on the state should be done
only after each block, and not after each transaction.

<a id="packages.valory.skills.abstract_round_abci.base.AbstractRound.check_payload_type"></a>

#### check`_`payload`_`type

```python
def check_payload_type(transaction: Transaction) -> None
```

Check the transaction is of the allowed transaction type.

**Arguments**:

- `transaction`: the transaction

**Raises**:

- `None`: TransactionTypeNotRecognizedError if the transaction can be
applied to the current state.

<a id="packages.valory.skills.abstract_round_abci.base.AbstractRound.check_majority_possible_with_new_voter"></a>

#### check`_`majority`_`possible`_`with`_`new`_`voter

```python
def check_majority_possible_with_new_voter(
        votes_by_participant: Dict[str, BaseTxPayload],
        new_voter: str,
        new_vote: BaseTxPayload,
        nb_participants: int,
        exception_cls: Type[ABCIAppException] = ABCIAppException) -> None
```

Check that a Byzantine majority is achievable, once a new vote is added.

**Arguments**:

- `votes_by_participant`: a mapping from a participant to its vote,
before the new vote is added
- `new_voter`: the new voter
- `new_vote`: the new vote
- `nb_participants`: the total number of participants
- `exception_cls`: the class of the exception to raise in case the
check fails.

**Raises**:

- `None`: exception_cls: in case the check does not pass.

<a id="packages.valory.skills.abstract_round_abci.base.AbstractRound.check_majority_possible"></a>

#### check`_`majority`_`possible

```python
def check_majority_possible(

        nb_participants: int,
        exception_cls: Type[ABCIAppException] = ABCIAppException) -> None
```

Check that a Byzantine majority is still achievable.

The idea is that, even if all the votes have not been delivered yet,
it can be deduced whether a quorum cannot be reached due to
divergent preferences among the voters and due to a too small
number of other participants whose vote has not been delivered yet.

The check fails iff:

    nb_remaining_votes + largest_nb_votes < quorum

That is, if the number of remaining votes is not enough to make
the most voted item so far to exceed the quorum.

Preconditions on the input:
- the size of votes_by_participant should not be greater than
  "nb_participants - 1" voters
- new voter must not be in the current votes_by_participant

**Arguments**:

- `votes_by_participant`: a mapping from a participant to its vote
- `nb_participants`: the total number of participants
- `exception_cls`: the class of the exception to raise in case the
check fails.

**Raises**:

- `exception_cls`: in case the check does not pass.

<a id="packages.valory.skills.abstract_round_abci.base.AbstractRound.is_majority_possible"></a>

#### is`_`majority`_`possible

```python
def is_majority_possible(votes_by_participant: Dict[str, BaseTxPayload],
                         nb_participants: int) -> bool
```

Return true if a Byzantine majority is achievable, false otherwise.

**Arguments**:

- `votes_by_participant`: a mapping from a participant to its vote
- `nb_participants`: the total number of participants

**Returns**:

True if the majority is still possible, false otherwise.

```

CollectNonEmptyUntilThresholdRound

This class represents logic for rounds where a round needs to collect
optionally different payloads from k of n agents, where we only keep the non-empty attributes.

`done_event` is emitted when a) the required block confirmations
have been met, b) the collection threshold (k of n) is reached, and
c) some non-empty attribute values have been collected. In this case
all payloads are saved under `collection_key`. Under `selection_key`
the non-empty attribute values are stored.

`none_event` is emitted when a) the required block confirmations
have been met, b) the collection threshold (k of n) is reached, and
c) no non-empty attribute values have been collected.

Attention: A `none_event` might be triggered even though some of the
remaining n-k agents might send non-empty attributes! Extended
`required_block_confirmations` can alleviate this somewhat.

#### reset`_`state

```python
def reset_state(restart_from_round: str,
                round_count: int,
                serialized_db_state: Optional[str] = None) -> None
```

This method resets the state of RoundSequence to the beginning of the period.

Note: This is intended to be used for agent <-> tendermint communication recovery only!

**Arguments**:

- `restart_from_round`: from which round to restart the abci.
This round should be the first round in the last period.
- `round_count`: the round count at the beginning of the period -1.
- `serialized_db_state`: the state of the database at the beginning of the period.
If provided, the database will be reset to this state.

## PendingOffencesPayload Objects

```python
@dataclass(frozen=True)
class PendingOffencesPayload(BaseTxPayload)
```

Represent a transaction payload for pending offences.

## PendingOffencesRound Objects

```python
class PendingOffencesRound(CollectSameUntilThresholdRound)
```

Defines the pending offences background round, which runs concurrently with other rounds to sync the offences.

#### `__`init`__`

```python
def __init__(*args: Any, **kwargs: Any) -> None
```

Initialize the `PendingOffencesRound`.

<a id="packages.valory.skills.abstract_round_abci.base.PendingOffencesRound.offence_status"></a>

#### offence`_`status

```python
@property
def offence_status() -> Dict[str, OffenceStatus]
```

Get the offence status from the round sequence.

<a id="packages.valory.skills.abstract_round_abci.base.PendingOffencesRound.end_block"></a>

#### end`_`block

```python
def end_block() -> None
```

Process the end of the block for the pending offences background round.

It is important to note that this is a non-standard type of round, meaning it does not emit any events.
Instead, it continuously runs in the background.
The objective of this round is to consistently monitor the received pending offences
and achieve a consensus among the agents.
