Ethereum: Unable to match aggregation_bits with committee validators

Beacon Ethereum node API: attaching validation to a specific nest

review

In this article, we will examine how to interact with the API Ethereum Beacon interface to download information about validators confirming specific gaps. This includes calling the ending point /eth/v1/beacon/state/'and using its parameter scratches for filtering results.





Preliminary requirements


You have an Ethereum account (e.g. Mainnet, TestNet)



You know the protocol Ethereum Beacon and his API



You have the necessary permissions to access a specific nest




Interaction with the API of the Beacon node

To download information about validations confirming a specific nest, you can call the end point "/ETH/V1/Beacon/States/. Here is an example of how to do it:

`Bash



Curl -x Get \

   \

  -Data-Urlencode "Q = 0x1234567890ABCDEF & Slot = 15687030" \

  -Header "Content type: application/json"

Replace `ok_projekt_id with your Infura design ID and the slots number (in hexadecimal format).

isolation of information about the validate

The API will include the “Validator” object, each of which represents the Walidator. To extract the information you need, you will want to iterate the board and find validators that match specific criteria.

Here is an example code in Python using the “Requests” library:

`Python



Import requests

Def Get_Validators (automatic):

    url = f " (Slot}"

    response = requests.get (url, headlines = {'content-type': 'Application/Json'})

    Data = response.json ()


    Walidacze = []

    For data validation ["gaps"]:

        If Validator ['Validator_id'] == BLOT:

            Walidators.append (Walidator)


    Return validators




Sample use

Slot = 15687030

Validators = Get_Validators (nest)

For the validator in proven validations:

    print (f "Waliator ID: {Validator ['Validator_id']}")



Additional information about checking the correctness (e.g. name, address)

filtering by name or address

If you want to filter the results based on a specific name or coating address, you will want to modify the “Get_Validators” function to search for validators that match your criteria.

For example:

`Python



Def Get_Validators (Fabrics, Filters):

    url = f " (Slot}"

    Params = {'Q': 'or'. Join (f "validator.name = '{filtro

    response = requests.get (url, headlines = {'content-type': 'application/json'}, params = params)


    Data = response.json ()

    Walidacze = []

    For data validation ["gaps"]:

        If similar (filter in Validator ['Valitator_id']. Lower () or filter in Validator ['vavellator_address'].

            Walidators.append (Walidator)


    Return validators

Remember that you can use different types of filters, such as name, address, contract and many others.

Application

By following these steps, you should be able to interact with the API Ethereum Beacon interface to download information about validators confirming specific gaps. Remember to always verify your Infura project ID and make sure your network is compatible with the Beacon protocol before starting this code in production.
