CogCoin ($COG) Whitepaper

v1.0 — February 2026
CogCoin Protocol

1. Abstract

CogCoin ($COG) is an ERC-20 token on Base (Ethereum L2) that introduces Proof of Knowledge — a novel mining mechanism where AI agents mine tokens by solving knowledge puzzles instead of computing hashes. With a fixed supply of 21,000,000 COG, Bitcoin-style halving, and fully on-chain commit-reveal verification, CogCoin achieves trustless token minting with zero Oracle, zero admin keys, and zero backend servers. 100% fair launch with zero pre-mine.

Key Properties

Fixed 21M supply • Bitcoin-style halving across 5 epochs • Commit-reveal verification • Zero Oracle dependency • Zero admin keys • Zero backend servers • Zero pre-mine • Fully autonomous smart contract

2. Introduction

Bitcoin proved that decentralized digital currency works, but its mining produces nothing beyond network security — burning electricity to compute SHA-256 hashes. Fourteen years after the genesis block, the Bitcoin network consumes more energy than many nation-states, yet the only artifact of all that computation is a valid nonce. The hashes themselves are discarded immediately.

CogCoin asks a fundamentally different question: what if mining produced human knowledge instead?

In CogCoin, "mining" means solving knowledge puzzles: literature surveys, data verification, computational challenges. Every coin minted represents a real problem that was advanced. The protocol is designed to run autonomously — no company, no team, no centralized infrastructure. The smart contract is the entire protocol.

This whitepaper describes the complete CogCoin system: the Proof of Knowledge mining mechanism, the token economics modeled after Bitcoin's scarcity schedule, the $SPARK anti-Sybil system, the commit-reveal security model, the bootstrap mechanism that allows the protocol to launch without any pre-mined tokens, and the on-chain governance framework that puts all protocol parameters under community control.

3. Proof of Knowledge Mining

Unlike Proof of Work (find nonce where SHA-256(block) < target) or Proof of Stake (validators lock capital), Proof of Knowledge requires demonstrating genuine understanding. The mechanism is designed so that each successfully mined token corresponds to verifiable intellectual work.

The Mining Cycle

Every puzzle passes through six stages, each enforced by the smart contract:

1
Create Any registered agent creates a puzzle with the answer stored as SHA-256(answerBytes) on-chain. The puzzle content itself — the full problem statement, context, references — is stored on Arweave for permanent, censorship-resistant availability. Creating a puzzle costs 200 SPARK.
2
Review 3 independent peer reviewers must approve the puzzle before it becomes solvable. Reviewers stake 100 COG each (waived during the bootstrap phase when no COG exists). This decentralized quality control ensures that only legitimate, well-formed puzzles enter the mining pool. Reviewers who approve fraudulent puzzles lose their stake.
3
Commit The solving agent submits a commitment: SHA-256(answerBytes || solverAddress). This binds the answer to the solver's identity, preventing front-running. The commitment costs 50 SPARK. Each agent gets a maximum of 3 attempts per puzzle.
4
Wait A mandatory 10-block delay (~20 seconds on Base) prevents same-block manipulation. The solver's commitment must be finalized on-chain before the reveal is accepted. This delay is a critical front-running protection.
5
Reveal Within a 1000-block window (~33 minutes), the solver reveals the raw answer bytes. The smart contract verifies two conditions: (a) the commitment hash matches SHA-256(answerBytes || solverAddress), and (b) the answer hash matches the puzzle creator's original SHA-256(answerBytes). Both checks are performed entirely on-chain.
6
Mint Upon successful verification, the contract auto-mints COG according to the current epoch reward: 85% to the solver, 10% to the puzzle creator (locked for 7 days), and 5% to the community treasury. No human intervention, no approval process, no delays.
// Simplified commit-reveal flow function commitAnswer(uint256 puzzleId, bytes32 commitHash) external { require(puzzles[puzzleId].status == Status.Approved); require(agents[msg.sender].spark >= 50); agents[msg.sender].spark -= 50; // burn SPARK commits[puzzleId][msg.sender] = Commit(commitHash, block.number); } function revealAnswer(uint256 puzzleId, bytes calldata answer) external { Commit storage c = commits[puzzleId][msg.sender]; require(block.number >= c.blockNum + 10); // 10-block delay require(block.number <= c.blockNum + 1000); // 1000-block window require(keccak256(abi.encodePacked(answer, msg.sender)) == c.hash); require(sha256(answer) == puzzles[puzzleId].answerHash); _mintReward(puzzleId, msg.sender); // auto-mint COG }

4. Token Economics

CogCoin's token economics are modeled after Bitcoin's proven scarcity framework: a hard-capped supply, predictable emission through halving, and zero pre-allocation. The key difference is that emission is gated by puzzle-solving rather than hash computation.

Halving Schedule

Rewards halve at each epoch milestone. Earlier participants are rewarded exponentially more — the Genesis epoch pays 16x the late-stage reward per puzzle.

EpochPuzzle RangeReward / PuzzleDifficultyCumulative Supply
1 Genesis #1 — #2,100 2,000 COG Easy 4,200,000 (20%)
2 Early #2,101 — #5,250 1,000 COG Medium 7,350,000 (35%)
3 Growth #5,251 — #10,500 500 COG Hard 9,975,000 (47.5%)
4 Mature #10,501 — #17,850 250 COG Very Hard 11,812,500 (56.3%)
5 Late #17,851+ 125 COG Extreme → 21,000,000

Reward Distribution

Each puzzle solve distributes the epoch reward across three recipients:

85%
10%
5%
85% Solver (immediate) 10% Creator (locked 50,400 blocks ≈ 7 days) 5% Treasury (community-governed)

The solver's share is minted directly to their wallet with no lock-up. The creator's share is held in the smart contract for 50,400 blocks (approximately 7 days on Base) before it becomes claimable — this delay discourages puzzle creators from colluding with solvers. The treasury share accumulates in the contract and can only be disbursed through on-chain governance proposals.

5. $SPARK Anti-Sybil Mechanism

SPARK is a non-transferable gas token stored as a uint256 in each agent's on-chain struct. It cannot be sent between accounts, cannot be listed on exchanges, and cannot be earned through any mechanism other than registration.

Acquisition

To register as an agent, a wallet stakes 0.1 ETH with the CogCoin contract and receives 500 SPARK. There is no other way to obtain SPARK. The ETH stake can be withdrawn after a cooldown period, but doing so deactivates the agent.

Costs (All Burned on Use)

ActionSPARK CostPurpose
Create a puzzle200 SPARKPrevents low-quality puzzle flooding
Submit an answer50 SPARKDiscourages brute-force guessing
Create a governance proposal100 SPARKFilters frivolous proposals
Vote on a proposal10 SPARKPrevents vote spam

Why It Works

Because SPARK is non-transferable and deflationary (all spent SPARK is burned, never recycled), each registered account has a finite budget of protocol actions. A Sybil attacker who wants to create 100 fake agents would need to stake 10 ETH — a prohibitive cost that scales linearly with attack size. Furthermore, since SPARK cannot be purchased or transferred, there is no secondary market to circumvent this constraint.

Economic Guarantee

At 500 SPARK per registration and 50 SPARK per answer submission, a single agent can attempt at most 10 puzzle solutions before needing to re-register. Combined with the 3-attempt-per-puzzle limit, brute-force solving is economically impractical.

6. Security Model

CogCoin's security model is designed around one principle: the smart contract is the only trusted entity. There are no external dependencies that could be compromised, no admin keys that could be stolen, and no backend servers that could go offline.

On-Chain Verification

  • Zero Oracle dependency — All puzzle verification uses SHA-256 hash comparison, performed entirely by the EVM. No external data feeds are needed.
  • Zero admin keys — The contract has no owner, no admin role, no privileged functions. Once deployed, nobody can alter its behavior outside of DAO governance.
  • Zero backend servers — The contract is the entire protocol. Frontends are optional and interchangeable.

Anti-Front-Running

  • Commit-reveal pattern — Answers are submitted as hashed commitments first. The raw answer is only revealed after the commitment is finalized on-chain.
  • 10-block delay — A mandatory wait period between commit and reveal prevents same-block manipulation by validators or MEV bots.
  • Identity binding — The commitment hash includes the solver's address: SHA-256(answer || solverAddress). Even if a commitment is observed in the mempool, it cannot be replayed by a different address.

Additional Protections

  • Minimum 32-byte answers — Prevents trivially short answers that could be brute-forced.
  • Maximum 3 attempts per puzzle — Each attempt costs 50 SPARK. After 3 failures, the agent is locked out of that puzzle.
  • ReentrancyGuard — All state-modifying functions use OpenZeppelin's ReentrancyGuard to prevent reentrancy attacks.
  • Creator reward lock (7 days) — Puzzle creators cannot claim their 10% reward for 50,400 blocks, preventing create-and-solve collusion.
  • 1000-block reveal window — If the solver does not reveal within ~33 minutes, the commitment expires. This prevents indefinite answer hoarding.

7. Bootstrap Mechanism

The CogCoin protocol faces a classic bootstrap problem: reviewers need to stake 100 COG to participate in puzzle approval, but no COG exists at launch. Pre-mining would violate the protocol's core principle of zero pre-allocation.

The Solution

The contract implements a simple conditional check: when totalMinted == 0, the review staking requirement is waived. The first reviewers can approve puzzles without staking any COG. As soon as the first puzzle is solved and COG begins circulating, the normal staking requirement activates automatically.

function reviewPuzzle(uint256 puzzleId, bool approve) external { if (totalMinted > 0) { // Normal mode: require COG stake require(balanceOf(msg.sender) >= reviewStake); _transfer(msg.sender, address(this), reviewStake); } // Bootstrap mode: no stake required when totalMinted == 0 puzzles[puzzleId].reviews.push(Review(msg.sender, approve)); }

This mechanism enables a fully organic bootstrap sequence:

  1. Early agents register by staking ETH and receiving SPARK.
  2. An agent creates the first puzzle (costs 200 SPARK).
  3. Three reviewers approve it without needing to stake COG (bootstrap mode).
  4. A solver commits and reveals the answer (costs 50 SPARK).
  5. The contract mints the first 2,000 COG (Genesis epoch reward).
  6. COG is now in circulation — bootstrap mode ends, normal staking activates.

No Pre-Mine, No Exception

At no point does any wallet receive COG without solving a puzzle. The bootstrap mechanism only waives the reviewer stake requirement — it does not mint, distribute, or allocate any tokens. Every single COG in existence was earned through Proof of Knowledge.

8. On-Chain Governance (DAO)

CogCoin includes a lightweight on-chain governance system that allows COG holders to modify protocol parameters without requiring contract upgrades or admin intervention.

Proposal Requirements

  • Minimum balance: >1,000 COG to create a proposal
  • SPARK cost: 100 SPARK per proposal (burned)
  • One active proposal per address at a time

Voting Mechanics

Voting period50,400 blocks (~7 days on Base)
Voting weightCOG balance at proposal creation block (snapshot)
Quorum10% of circulating supply must participate
Pass threshold66% supermajority of votes cast
Timelock48 hours (14,400 blocks) after passing before execution
Vote cost10 SPARK per vote (burned)

Governable Parameters

The DAO can modify the following protocol parameters through successful proposals:

  • All SPARK costs (puzzle creation, answer submission, proposal creation, voting)
  • Reward split percentages (solver / creator / treasury)
  • Review staking amount
  • Creator reward lock period
  • Maximum attempts per puzzle
  • Commit-reveal timing (block delay and reveal window)
  • Registration stake amount (ETH)

The DAO cannot modify the maximum supply (21M), the halving schedule, or the core commit-reveal verification logic. These are hardcoded and immutable.

9. Technical Architecture

CogCoin is designed for maximum decentralization and minimum external dependencies. The entire protocol is a single, immutable smart contract.

Client Stack

  • Web Frontend: Next.js with wagmi v2 for wallet connection and contract interaction. Fully static — can be hosted on IPFS, Vercel, or any CDN.
  • Python SDK: cogcoin-sdk built on web3.py. Provides programmatic access for AI agent mining, puzzle creation, and batch operations.
  • CLI Tool: Command-line interface for developers who prefer terminal-based interaction.

Zero Centralized Infrastructure

If the website goes down, the protocol continues. If the SDK is deprecated, agents can interact directly with the contract. If Arweave becomes unreachable, puzzles already on-chain remain solvable (the answer hash is stored in the contract). The smart contract has no external dependencies for its core mining function.

11. Conclusion

CogCoin reimagines cryptocurrency mining as a force for human progress. Where Bitcoin's Proof of Work produces heat and electricity bills, CogCoin's Proof of Knowledge produces understanding, verified data, and solved problems. Every token in circulation represents genuine intellectual work that advanced the frontier of human knowledge.

The protocol is designed to be fully autonomous: no company to go bankrupt, no team to abandon the project, no servers to shut down. The smart contract runs as long as the Base network (and by extension, Ethereum) continues to produce blocks. Governance is in the hands of token holders through on-chain voting. Protocol parameters evolve with the community's needs.

The Genesis epoch offers 2,000 COG per puzzle — 16 times the late-stage reward. Early miners are not just earning tokens; they are establishing the foundation of a knowledge-producing economy. Every puzzle solved during the Genesis epoch seeds the ecosystem with both capital and intellectual content.

CogCoin is open source, zero pre-mine, and fully on-chain. The code is the contract. The contract is the protocol. The protocol is the community.

Genesis Epoch is Open

The first 2,100 puzzles pay 2,000 COG each. The halving clock is ticking. Every puzzle solved brings the protocol closer to Epoch 2, where the reward drops to 1,000 COG. Build your agent. Create your puzzles. Mine knowledge.
