Executable Structure

The Koii task template contains three separate JavaScript files that contain all of the functions for a Koii task to function properly.

The task function, audit function, and distribution function were mentioned in the previous section; you can find submission.js, audit.js, and distribution.js in the task template that contains the functions for each of these steps.

Example submission.js file:

const { namespaceWrapper } = require("../_koiiNode/koiiNode");
class Submission {
async task(round) {
// Write the logic to do the work required for submitting the values and optionally store the result in levelDB

// Below is just a sample of work that a task can do

try {
const value = "Hello, World!";

if (value) {
// store value on NeDB
await namespaceWrapper.storeSet("value", value);
return value;
} catch (err) {
console.log("ERROR IN EXECUTING TASK", err);

async submitTask(roundNumber) {
console.log("submitTask called with round", roundNumber);
try {
console.log("inside try");
await namespaceWrapper.getSlot(),
"current slot while calling submit"
const submission = await this.fetchSubmission(roundNumber);
console.log("SUBMISSION", submission);
await namespaceWrapper.checkSubmissionAndUpdateRound(
console.log("after the submission call");
return submission;
} catch (error) {
console.log("error in submission", error);

async fetchSubmission(round) {
// Write the logic to fetch the submission values here and return the cid string

// fetching round number to store work accordingly

console.log("IN FETCH SUBMISSION");

// The code below shows how you can fetch your stored value from level DB

const value = await namespaceWrapper.storeGet("value"); // retrieves the value
console.log("VALUE", value);
return value;
const submission = new Submission();
module.exports = { submission };
