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 ProblemCurrent "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 SolutionValidators 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 VerificationEvery 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 OperatorsExoHash 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).
LPCommunity-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
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
RegulationOperators 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.
