governance

Klaytn 거버넌스와 관련한 API입니다.

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

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.field의 형식으로 되어 있습니다.

  • Value : 각 키에 대한 다양한 형태의 값입니다.

Return Value

Example

> governance.vote ("governance.governancemode", "ballot")
"Your vote was successfully placed."

> governance.vote ("governance.governingnode", "0x12345678990123456789901234567899012345678990")
"Your vote was successfully placed."

> governance.vote("istanbul.epoch", 604800)
"Your vote was successfully placed."

> governance.vote("governance.unitprice", 25000000000)
"Your vote was successfully placed."

> governance.vote("istanbul.committeesize", 7)
"Your vote was successfully placed."

> governance.vote("reward.mintingamount", "9600000000000000000")
"Your vote was successfully placed."

> governance.vote("reward.ratio", "40/30/30")
"Your vote was successfully placed."

> governance.vote("reward.useginicoeff", false)
"Your vote was successfully placed."

// If wrong data are given
> governance.vote("reward.ratio", 100)
"Your vote couldn't be placed. Please check your vote's key and value"

> governance.vote("governance.governingnode", 1234)
"Your vote couldn't be placed. Please check your vote's key and value"

// when `governancemode` is "single" and the node is not `governingnode`
> governance.vote("governance.governancemode", "ballot")
"You don't have the right to vote"

governance_showTally

showTally 속성은 거버넌스 투표의 현재 집계를 제공합니다. 집계된 찬성률을 백분율로 나타냅니다. 50%가 넘으면 해당 의제는 통과됩니다.

Parameters

None

Return Value

Example

> governance.showTally
[{
    ApprovalPercentage: 36.2,
    Key: "unitprice",
    Value: 25000000000
}, {
    ApprovalPercentage: 72.5,
    Key: "mintingamount",
    Value: "9600000000000000000"
}]

governance_totalVotingPower

totalVotingPower 속성은 CN들이 보유한 의결권 합계를 나타냅니다. 각 CN은 1.0 ~ 2.0의 의결권을 가집니다. "none", "single" 거버넌스 모드에서는 totalVotingPower 속성을 통해 제공하는 정보가 없습니다.

Parameters

None

Return Value

Example

// In "ballot" governance mode
> governance.totalVotingPower
32.452

// In "none", "single" governance mode
> governance.totalVotingPower
"In current governance mode, voting power is not available"

governance_myVotingPower

myVotingPower 속성은 노드가 보유한 의결권을 나타냅니다. The voting power can be 1.0 ~ 2.0. In "none", "single" governance mode, totalVotingPower don't provide any information.

Parameters

None

Return Value

Example

// In "ballot" governance mode
> governance.myVotingPower
1.323

// In "none", "single" governance mode
> governance.myVotingPower
"In current governance mode, voting power is not available"

governance_myVotes

myVotes 속성은 투표 주기 동안의 투표 정보를 나타냅니다. 사용자의 노드가 새로운 블록을 생성할 때 각 투표가 블록에 저장됩니다. 현재 투표 주기가 종료되면 이 정보는 사라집니다.

Parameters

None

Return Value

Example

> governance.vote("governance.governancemode", "ballot")
"Your vote was successfully placed."

> governance.myVotes
[{
    BlockNum: 403,
    Casted: true,
    Key: "governance.governancemode",
    Value: "ballot"
}]

governance_getChainConfig

governance_chainConfig

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

governance_chainConfig API will be deprecated since Klaytn v1.11 (see klaytn#1783). Use 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.

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.

Parameters

None

Return Value
