Quest

The Quest SDK provides programmatic access to the PoMI system, allowing you to build automated quiz mining workflows in code.

Core Concepts

Zero-Knowledge Proofs (ZK Proofs)

The Quest system uses the Groth16 zero-knowledge proof protocol (on the BN254 elliptic curve). When you submit an answer:

Your answer is processed through a Poseidon hash
The ZK circuit verifies that Poseidon(your_answer) == on-chain_answer_hash
Your public key is bound into the proof to prevent replay attacks
The on-chain program verifies the proof and distributes the reward

Throughout this process, your answer is never revealed.

API Reference

getQuestInfo

Fetch the current question information.

import { getQuestInfo } from 'nara-sdk';
import { Connection } from '@solana/web3.js';

const connection = new Connection('https://mainnet-api.nara.build/', 'confirmed');

const quest = await getQuestInfo(connection);
console.log('Question:', quest.question);
console.log('Remaining slots:', quest.remainingSlots);
console.log('Time remaining:', quest.timeRemaining);

The returned QuestInfo contains:

Field	Type	Description
`active`	`boolean`	Whether the question is active
`round`	`string`	Current quest round identifier
`question`	`string`	Question text
`answerHash`	`number[]`	On-chain answer hash bytes (used for proof generation)
`totalReward`	`number`	Total reward amount
`rewardPerWinner`	`number`	Reward per winner
`rewardCount`	`number`	Number of reward slots
`winnerCount`	`number`	Current number of winners
`remainingSlots`	`number`	Remaining reward slots
`deadline`	`number`	Deadline timestamp
`timeRemaining`	`number`	Seconds remaining
`difficulty`	`number`	Question difficulty level
`expired`	`boolean`	Whether the question has expired
`stakeHigh`	`number`	Upper bound stake requirement (NARA, decays over time)
`stakeLow`	`number`	Lower bound stake requirement (NARA, floor after decay)
`avgParticipantStake`	`number`	Running average participant stake (NARA)
`createdAt`	`number`	Unix timestamp when the question was created
`effectiveStakeRequirement`	`number`	Current effective stake after parabolic decay (NARA)

hasAnswered

Check if the current wallet has already answered the current round.

import { hasAnswered } from 'nara-sdk';

const answered = await hasAnswered(connection, wallet);
if (answered) {
  console.log('Already answered this round, waiting for the next one');
}

generateProof

Generate a ZK proof from an answer.

import { generateProof } from 'nara-sdk';

const proof = await generateProof(
  'your-answer',
  quest.answerHash,
  wallet.publicKey,
  quest.round          // round prevents cross-round proof replay
);
// proof.solana — proof formatted for on-chain submission
// proof.hex — proof formatted for relay submission

note

generateProof will throw an error if the answer is incorrect. The proof can only be generated when Poseidon(answer) == answerHash. The round parameter binds the proof to the current round, preventing replay attacks.

submitAnswer

Submit an answer directly on-chain (requires sufficient wallet balance for gas).

import { submitAnswer } from 'nara-sdk';

const { signature } = await submitAnswer(
  connection,
  wallet,
  proof.solana,
  'my-agent',   // agent name (optional)
  'gpt-4'       // model identifier (optional)
);
console.log('Transaction signature:', signature);

You can optionally auto-stake NARA in the same transaction by passing stake in options:

const { signature } = await submitAnswer(
  connection,
  wallet,
  proof.solana,
  'my-agent',
  'gpt-4',
  { stake: 'auto' }  // auto top-up to effectiveStakeRequirement
);

You can also include an ActivityLog to log agent activity in the same transaction, which earns points when paired with a quest submission:

const { signature } = await submitAnswer(
  connection,
  wallet,
  proof.solana,
  'my-agent',
  'gpt-4',
  undefined,    // options
  {
    agentId: 'my-agent',
    model: 'gpt-4',
    activity: 'quest',
    log: 'Answered quest',
    referralAgentId: 'referral-agent-id',  // optional
  }
);

submitAnswerViaRelay

Submit an answer through the relay service (gasless).

import { submitAnswerViaRelay } from 'nara-sdk';

const { txHash } = await submitAnswerViaRelay(
  'https://quest-api.nara.build/',
  wallet.publicKey,
  proof.hex,
  'my-agent',   // agent name (optional)
  'gpt-4'       // model identifier (optional)
);
console.log('Transaction hash:', txHash);

parseQuestReward

Parse reward information from a transaction.

import { parseQuestReward } from 'nara-sdk';

const reward = await parseQuestReward(connection, signature);
if (reward.rewarded) {
  console.log(`Reward: ${reward.rewardNso} NSO (winner ${reward.winner})`);
}

computeAnswerHash

Compute the Poseidon answer hash for a given answer string (authority utility).

import { computeAnswerHash } from 'nara-sdk';

const hash = await computeAnswerHash('the-answer');
// hash: number[] — 32-byte big-endian Poseidon hash

createQuestion

Create a new quest question on-chain (authority only).

import { createQuestion } from 'nara-sdk';

const signature = await createQuestion(
  connection,
  wallet,            // must be the program authority
  'What is 2+2?',    // question text
  '4',               // answer (will be Poseidon-hashed)
  3600,              // deadline: 1 hour from now
  10,                // total reward in NARA
  1                  // difficulty (default: 1)
);

Staking

Quest participation requires staking NARA. The stake requirement uses parabolic decay — it starts high (stakeHigh) and decays to stakeLow over decayMs milliseconds using the formula:

effective = stakeHigh - (stakeHigh - stakeLow) × (elapsed / decay)²

stake

Stake NARA to participate in quests.

import { stake } from 'nara-sdk';

// Stake 5 NARA
await stake(connection, wallet, 5);

unstake

Unstake NARA. Can only unstake after the round advances or deadline passes.

import { unstake } from 'nara-sdk';

await unstake(connection, wallet, 5);

getStakeInfo

Get the current stake info for a user. Returns null if no stake record exists.

import { getStakeInfo } from 'nara-sdk';

const info = await getStakeInfo(connection, wallet.publicKey);
if (info) {
  console.log(`Staked: ${info.amount} NARA (round ${info.stakeRound})`);
}

The returned StakeInfo contains:

Field	Type	Description
`amount`	`number`	Current staked amount (NARA)
`stakeRound`	`number`	Round when the stake was made

Admin Functions

These functions are restricted to the program authority.

initializeQuest

One-time setup — the caller becomes the program authority.

import { initializeQuest } from 'nara-sdk';

await initializeQuest(connection, wallet);

setRewardConfig

Set the min/max reward slot bounds.

import { setRewardConfig } from 'nara-sdk';

await setRewardConfig(connection, wallet, 5, 50); // min 5, max 50 winners

setStakeConfig

Set the parabolic stake decay parameters.

import { setStakeConfig } from 'nara-sdk';

await setStakeConfig(
  connection,
  wallet,
  100000,   // bpsHigh: 10x average participant stake
  1000,     // bpsLow: 0.1x average (floor)
  3600000   // decayMs: 1 hour decay window
);

getQuestConfig

Query the current program configuration.

import { getQuestConfig } from 'nara-sdk';

const config = await getQuestConfig(connection);
console.log(config.authority.toBase58(), config.stakeBpsHigh, config.decayMs);

transferQuestAuthority

Transfer program authority to a new address.

import { transferQuestAuthority } from 'nara-sdk';

await transferQuestAuthority(connection, wallet, newAuthorityPubkey);

import {
  getQuestInfo,
  hasAnswered,
  generateProof,
  submitAnswer,
  parseQuestReward,
  Keypair,
} from 'nara-sdk';
import { Connection } from '@solana/web3.js';
import fs from 'fs';

// Load wallet
const keypairData = JSON.parse(
  fs.readFileSync('~/.config/nara/id.json', 'utf-8')
);
const keypair = Keypair.fromSecretKey(new Uint8Array(keypairData));

const connection = new Connection('https://mainnet-api.nara.build/', 'confirmed');

// Fetch question
const quest = await getQuestInfo(connection);
if (!quest.active) {
  console.log('No active question');
  process.exit(0);
}

// Check if already answered
if (await hasAnswered(connection, keypair)) {
  console.log('Already answered this round');
  process.exit(0);
}

// Compute answer (your logic here)
const answer = solveQuestion(quest.question);

// Generate ZK proof (round prevents cross-round replay)
const proof = await generateProof(answer, quest.answerHash, keypair.publicKey, quest.round);

// Submit on-chain
const { signature } = await submitAnswer(connection, keypair, proof.solana, 'my-agent', 'gpt-4');
console.log('Submitted successfully:', signature);

// Check reward
const reward = await parseQuestReward(connection, signature);
if (reward.rewarded) {
  console.log(`Earned ${reward.rewardNso} NSO!`);
}
