[ANN] ExoHash — Sovereign L1 for Provably Fair Gaming

ExoHash — Sovereign Cosmos SDK Layer 1
Native BLS Randomness Every Block • Protocol-Enforced Solvency
The First L1 Where the House Can't Cheat and Can't Go Broke
Devnet is Live Now

What is ExoHash?

ExoHash is a sovereign Cosmos SDK Layer 1 purpose-built for on-chain iGaming (casinos, virtual sports, etc.).

Randomness is generated inside consensus by the validator set using BLS threshold signatures — no oracles, no commit-reveal, no single-party trust.
Every bet is automatically 100% collateralized at the protocol level before acceptance.

The Problem
Current "provably fair" crypto casinos rely on:
• Oracle VRF (async, expensive, MEV-vulnerable)
• Commit-reveal schemes (griefable, 2 tx)
• Self-attested RNG ("trust us")

None produce randomness that finalizes with the block. None enforce solvency on-chain.

Our Solution
Validators run BLS12-381 Distributed Key Generation (DKG).
Every block, a threshold (22-of-32) signs the block height → aggregate BLS signature → SHA256 hash becomes the beacon seed.

• Unpredictable until the block finalizes
• Unbiasable (deterministic message)
• Fully verifiable on-chain/explorer
• Instant (~600ms block time)

Key Specifications

Consensus: CometBFT + ABCI++ vote extensions
Block time: ~600ms
Target throughput: ~250 bets/second
Player experience: Gasless
Settlement: USDC (via IBC)
Solvency: Worst-case payout reserved before bet acceptance
Randomness: BLS threshold signatures + SHA256 derivation
Validators at genesis: 32 (equal voting power)

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Native Games (Chain Modules, Not Smart Contracts)
• Crash, Dice, Mines, Boxing (parimutuel)
• Coming soon: Plinko, Limbo, Keno, Slots

Three engine types: Arena (multiplayer), Instant, Step (sequential).

Built-in Verification
Every bet includes a cryptographic proof:
BLS Signature (96 bytes) → SHA256 → Beacon Seed → Per-bet derivation → Result.
Click "Verify" on any bet — see the exact math. Check the block explorer for full audit trail.

For Operators
ExoHash is infrastructure, not a casino.
Create bankroll → launch games → set house edge. Protocol handles randomness, settlement & solvency.
You keep 75% of the house edge. Protocol takes 25% (paid in USDC to validators & EXOH stakers).

LP
Community-driven bankrolls: anyone can deposit USDC and earn the house edge as a liquidity provider.

Token: EXOH
• Zero inflation • No emissions
• Real yield in USDC from protocol revenue
• Governance: fee splits, game params, upgrades
• Listing planned only after mainnet + actual volume

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Regulation
Operators bring their own B2C license. ExoHash wil obtain B2B licensing (Isle of Man blockchain supplier, Malta MGA) + GLI-19 RNG certification.

Team
• Founder — PhD Nuclear Physics (TU Delft), HFT/stat arb since 2007, institutional risk management (Swiss)
• Legal — O.M., iGaming regulatory counsel
• Post pre-seed: hiring game devops, frontend engineers, community lead

Planned: Swiss foundation in Zug.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Devnet Status
Live now:
• 3 validator nodes, BLS threshold randomness active
• 10 games across 5 bankrolls (crash, dice, mines, virtual sports - boxing)
• Full block explorer with BLS signature verification
• Built-in bet verification — cryptographic proof per bet
• ~600ms blocks, gasless, USDC settlement

Code will be open-sourced at mainnet.
