+### JSON-RPC API
+
+The following JSON-RPC method for the Klaytn node should be added to provide the registered bls public keys.
+
+- Name: `klay_getBlsInfos`
+- Description: Returns all registered bls public keys and proof-of-possessions of the validators.
+- Parameters:
+    - `number` - (optional) integer or hexadecimal block number, or the string "pending" or "latest".
+- Returns: A map of the addresses and their associated bls public keys, proof-of-possessions and verify error.
+    - `publicKey` - The compressed BLS12-381 public key in hex string.
+    - `pop` - The proof-of-possession in hex string.
+    - `verifyErr` - The error message of the verification. If the verification is successful, it returns null.

+#### JSON-RPC APIs
+
+The following JSON-RPC methods for the Klaytn node should be added to provide the records of registered system contracts.
+
+1. `klay_getActiveAddressFromRegistry`
+
+    - Parameters:
+        - `name`: the name of the system contract in string.
+        - `number`: (optional) integer or hexadecimal block number, or the string "pending" or "latest".
+    - Description: Returns the active address of the system contract registered as `name` if exists.
+    - Return: The address of the active system contract.
+    - Example
+        ```json
+        // Request
+        curl -X POST -H "Content-Type: application/json" --data '{"jsonrpc":"2.0", "method":"klay_getActiveAddressFromRegistry", "params":["KIP113", "latest"],"id":1}' http://localhost:8551
+        // Response
+        {

+
+    - Parameters:

+        - `number`: (optional) integer or hexadecimal block number, or the string "pending" or "latest".
+    - Description: Returns all records of the system contract registered as `name` if it has been registered.
+    - Returns:
+        - `Record[]`: An array of the records of the system contract.
+            - `Record`: A struct of the record with the following fields.
+                - `addr`: The address of the system contract.
+                - `activation`: The block number when the system contract will be activated.
+    - Example
+        ```json
+        // Request
