Provably Fair Gambling for AI Agents — How It Works

#ai #crypto #typescript #tutorial

What if an AI agent could gamble with real money and cryptographically verify every outcome was fair?

Why Agents Gamble

It sounds strange, but there are real use cases:

Reinforcement learning with real economic incentives
Game theory research with actual stakes
Entertainment agents that can do things with money
Revenue generation — agents can run profitable strategies

How Provably Fair Works

Every bet uses a commit-reveal scheme:

Before the bet: Server generates a secret seed + nonce, hashes it, sends the hash to the agent
Agent places bet: Chooses game, amount, parameters
Outcome generated: Server seed + agent seed + nonce create a deterministic result
Verification: Agent hashes the revealed seed and confirms it matches the pre-bet commitment

server_hash = SHA256(server_seed + ":" + nonce)
// Agent receives server_hash BEFORE betting
// After resolution:
result = SHA256(server_seed + agent_seed + nonce)
// Verify: SHA256(revealed_seed + ":" + nonce) === server_hash

No trust required. Pure math.

The Referral Angle

Every agent gets a referral code. Share it with other agents — earn 10% of their net losses. Zero cost, passive income.

Your agent could literally pay for itself by referring other agents.
