valuter

This is a testnet evaluator tool that is linked with cosmologger database and extracts the winners information.

Install & development

The best way to install it is to do it through a bundle called testnet-evaluator.

Configuration

ENV Variables

• SERVING_ADDR: The serving address, where the Valuter APIs are accessible.

• POSTGRES_DB: The name of postgres database

• POSTGRES_USER: Database username

• POSTGRES_PASSWORD: Password for the database user

• POSTGRES_PORT: Port number of the database

• POSTGRES_HOST: Host address of the server running postgres

Config file

There is a config.json file, which has to be mapped into the app directory of the container. i.e. be in the same path of the executable.

Here is what is inside the conf file:

{
    "tasks":{
        
        "validators-genesis": {
            "max-winners" : 10,
            "reward": 480
        },
        "validators-joined": {
            "max-winners" : 10,
            "reward": 720
        },
       
        "jail-unjail": {
            "max-winners" : 10,
            "reward": 720
        },
        "staking": {
            "max-winners" : 10,
            "reward": 480
        },
        "gov": {
            "max-winners" : 10,
            "proposals": [1,2,3],
            "reward": 480          
        },
        "node-upgrade": {
            "max-winners" : 10,
            "reward": 480,
            "condition": {
                "upgrade-hight": 1000
            }
        },
        "uptime": {
            "max-winners" : 10,
            "reward": 480,
            "conditions": [{
                "start-hight": 100,
                "end-hight": 200,
                "uptime-percent": 0.80
            }]
        }
    },

    "api":{
        "rows-per-page" : 200
    }

}

tasks keeps the configs related to the tasks:

• max-winners: The maximum number of winners for the task.
• reward: The reward amount for the task

"gov": {
    "max-winners" : 10,
    "proposals": [1,2,3],
    "reward": 480          
},

• proposals: is a list of proposal Ids that participants need to vote for. The reward amount is calculated for each proposal vote. e.g. if there are 3 proposals and a user votes for two, they will get 2 x reward

"node-upgrade": {
    "max-winners" : 10,
    "reward": 480,
    "condition": {
        "upgrade-hight": 1000
    }
},

• condition.upgrade-hight: refers to a specific block height that the upgrade has to happen. We check if a validator has signed this particular block to pick the winners.

"uptime": {
    "max-winners" : 10,
    "reward": 480,
    "conditions": [{
        "start-hight": 100,
        "end-hight": 200,
        "uptime-percent": 0.80
    }]
}

• conditions holds the configs for multiple rounds of load bursts. Each round has three parameters:

• • start-hight: The beginning of the load burst.
• • end-hight: The end of the load burst.
• • uptime-percent: minimum uptime requirement.
