Block

The Default Block Parameter

Klaytn 상태 상에서 어떤 행위에 대한 요청이 있을 때 마지막의 기본 블록 매개변수가 블록의 번호를 결정합니다.

The following options are possible for the defaultBlock parameter:

  • HEX String - an integer block number

  • String "earliest" for the earliest/genesis block

  • String "latest" - for the latest mined block

  • "pending" 문자열 - 보류 중인 상태/트랜잭션입니다.

klay_blockNumber

가장 최근의 블록 번호를 반환합니다.

Parameters

None

Return Value

Type
Description

QUANTITY

Integer of the current block number the client is on.

Example

// Request
curl -H "Content-Type: application/json" --data '{"jsonrpc":"2.0","method":"klay_blockNumber","params":[],"id":83}' https://public-en-baobab.klaytn.net

// Result
{
  "jsonrpc": "2.0",
  "id":83,
  "result": "0xc94"
}

klay_getHeaderByNumber

참고: 이 API는 Klaytn v1.7.0.부터 지원됩니다.

Returns information about a header by number. 이 API는 RPC 호출로만 작동하며 자바스크립트 콘솔을 통해서는 작동하지 않습니다.

Parameters

klay_getStorageAt

Returns the value from a storage position at a given address.

Parameters

Type
Description

20-byte DATA

Address of the storage.

QUANTITY

Integer of the position in the storage.

QUANTITY | TAG | HASH

Integer or hexadecimal block number, or the string "earliest", "latest" or "pending" as in the default block parameter, or block hash.

NOTE: In versions earlier than Klaytn v1.7.0, only integer block number, the string "earliest" and "latest" are available.

Return Value

Type
Description

DATA

The value at this storage position.

Example

Calculating the correct position depends on the storage to retrieve. Consider the following contract deployed at 0x295a70b2de5e3953354a6a8344e616ed314d7251 by address 0x391694e7e0b0cce554cb130d723a9d27458f9298.

contract Storage {
    uint pos0;
    mapping(address => uint) pos1;

    function Storage() {
        pos0 = 1234;
        pos1[msg.sender] = 5678;
    }
}

Retrieving the value of pos0 is straight forward:

curl -H "Content-Type: application/json" --data '{"jsonrpc":"2.0", "method": "klay_getStorageAt", "params": ["0x295a70b2de5e3953354a6a8344e616ed314d7251", "0x0", "latest"], "id": 1}' https://public-en-baobab.klaytn.net

{"jsonrpc":"2.0","id":1,"result":"0x00000000000000000000000000000000000000000000000000000000000004d2"}

Retrieving an element of the map is harder. The position of an element in the map is calculated with:

keccak(LeftPad32(key, 0), LeftPad32(map position, 0))

This means to retrieve the storage on pos1["0x391694e7e0b0cce554cb130d723a9d27458f9298"] we need to calculate the position with:

keccak(decodeHex("000000000000000000000000391694e7e0b0cce554cb130d723a9d27458f9298" + "0000000000000000000000000000000000000000000000000000000000000001"))

The Klaytn console which comes with the klay library can be used to make the calculation

> var key = "000000000000000000000000391694e7e0b0cce554cb130d723a9d27458f9298" + "0000000000000000000000000000000000000000000000000000000000000001"
undefined
> klay.sha3(key, {"encoding": "hex"})
"0x6661e9d6d8b923d5bbaab1b96e1dd51ff6ea2a93520fdc9eb75d059238b8c5e9"

Now to fetch the storage:

curl -H "Content-Type: application/json" --data '{"jsonrpc":"2.0", "method": "klay_getStorageAt", "params": ["0x295a70b2de5e3953354a6a8344e616ed314d7251", "0x6661e9d6d8b923d5bbaab1b96e1dd51ff6ea2a93520fdc9eb75d059238b8c5e9", "latest"], "id": 1}' https://public-en-baobab.klaytn.net

{"jsonrpc":"2.0","id":1,"result":"0x000000000000000000000000000000000000000000000000000000000000162e"}
