# governance

네트워크 거버넌스를 위해 Klaytn은 다음과 같이 `governance` namespace의 API를 제공합니다.

Klaytn에는 세 가지 거버넌스 모드가 있습니다.

* `none`: 네트워크에 참여하는 모든 노드는 환경설정을 변경할 권리가 있습니다.
* `single`: 오직 하나의 특정 노드가 환경설정을 변경할 권리를 가집니다.
* `ballot`: 의결권이 있는 모든 노드가 환경설정 변경에 투표할 수 있습니다. 전체 의결권 중 절반 이상이 모이면 해당 의제는 통과됩니다.

거버넌스 모드 종류에 따라 제안자는 단위 가격, 최소 예치 금액 등 네트워크 파라미터에 대해 투표할 수 있습니다. 제안자가 되기 위해서 노드는 최소 기준 이상의 KLAY를 예치해야 합니다. 자격이 있는 노드들은 블록을 제안할 권리를 가지지만, 실제 제안자로 선정될 확률은 예치 금액에 따라 결정됩니다.

특정 기간 동안의 제안자 선정 슬롯(기회)의 수를 결정하기 위해 예치금 비율을 계산할 때 숫자 반올림으로 인해 노드에 슬롯이 한 개도 부여되지 않을 수 있습니다. 하지만 최소 기준 KLAY를 예치한 자격있는 노드에게는 슬롯이 보장됩니다.

노드가 자격이 없을 경우, 즉 노드가 충분한 양의 KLAY를 예치하지 않는다면, 블록을 제안하거나 검증할 기회가 주어지지 않을 것입니다.

**주의 사항**

* 거버넌스 노드는 예외적으로 `single` 모드에서 항상 자격이 있습니다.
* 블록이 제안될 때 투표가 이루어집니다. 이 투표는 블록이 제안된 주기를 포함한 두 주기 이후에 반영됩니다. 예외적으로 addValidator/removeValidator만 즉시 적용됩니다.

## governance\_vote <a href="#governance_vote" id="governance_vote"></a>

`vote` 메서드는 새로운 투표를 제출합니다. 거버넌스 모드에 의거하여 노드가 의결권을 가지는 경우 투표할 수 있습니다. 그렇지 않으면 오류 메시지가 반환되고 투표는 무시됩니다.

**Parameters**

* `Key` : 변경하고자 하는 환경설정의 이름입니다. 키는 `domain.field`의 형식으로 되어 있습니다.
* `Value` : 각 키에 대한 다양한 형태의 값입니다.

## governance\_chainConfig <a href="#governance_chainconfig" id="governance_chainconfig"></a>

The `chainConfig` property provides the latest chain configuration. This is equivalent to `chainConfigAt()` with an empty parameter.

{% hint style="warning" %}
`governance_chainConfig` API will be deprecated since Klaytn v1.11 (see [klaytn#1783](https://github.com/klaytn/klaytn/pull/1783)). Use [`governance_getChainConfig`](#governance_getchainconfig) instead.

NOTE: the RPC API will be deprecated since v1.11. However, the `governance.chainConfig` property in the Klaytn JavaScript console is removed since Klaytn v1.10.2.
{% endhint %}

{% hint style="success" %}
NOTE: In versions earlier than Klaytn v1.10.0, this API returned the initial chain configuration. However, due to its confusing name, it is updated since Klaytn v1.10.0. To query the initial chain configuration, use `chainConfigAt(0)` instead.
{% endhint %}

**Parameters**

None

**Return Value**

| Type | Description                 |
| ---- | --------------------------- |

## governance\_chainConfigAt <a href="#governance_chainconfigat" id="governance_chainconfigat"></a>

The `chainConfigAt` returns the chain configuration at a specific block. If the parameter is not set, it returns the chain configuration at the latest block.

{% hint style="warning" %}
`governance_chainConfigAt` API will be deprecated since Klaytn v1.11 (see [klaytn#1783](https://github.com/klaytn/klaytn/pull/1783)). Use [`governance_getChainConfig`](#governance_getchainconfig) instead.
