The 5-Layer Blockchain.
Read the whitepaper.

ABSTRACT A public blockchain built in five layers Ozone Chain is a public 5-layer blockchain. Its five layers (Network, Consensus, Application, Execution and Applications) combine the Cosmos SDK, CometBFT consensus and the Ethereum Virtual Machine (EVM). Applications get single-block finality and low fees, while developers keep using Solidity, MetaMask and the standard Ethereum toolchain.

OZONE is the network's native coin. It pays transaction fees, secures the chain through delegated staking and carries voting power in on-chain governance. OZONE has a fixed maximum supply of 50,000,000, an initial supply of 50,000 at launch, and a supply that can only shrink through burning.

This paper describes the network's architecture, consensus and governance, the OZONE token model, the application ecosystem and the roadmap from mainnet genesis on 1 July 2025.

Introduction Most applications must choose between Ethereum's developer ecosystem and the speed and cost of newer chains. Ozone Chain removes that trade-off by running the EVM on a Cosmos SDK chain with CometBFT finality.

1.1 The problem

Slow finality On many chains a payment is only safe after several confirmations, too slow for checkout, gaming and trading.

Unpredictable fees Congestion on large networks makes small payments and frequent in-app actions uneconomic.

Costly migration Chains with their own virtual machine force teams to rewrite contracts, rebuild tooling and retrain developers.

1.2 Ozone Chain's approach

1 Instant finality. A block is final the moment it is committed, with no reorganisations.

2 Low, stable fees paid in OZONE.

3 Full EVM compatibility. Existing Solidity contracts, wallets and developer tools work without changes.

4 Public governance. OZONE stakers decide network upgrades and parameters on-chain.

5 One ecosystem, one coin. Wallets, payments, commerce, media and publicinfrastructure applications all settle in OZONE.

The 5-Layer Architecture Each layer has one job, and each can be upgraded without disturbing the others: Network moves data, Consensus orders and finalises it, Application keeps the state, Execution runs smart contracts, and Applications serve users.

USERS AND DEVELOPERS FIGURE 1 LAYER 5 Applications dApps, wallets (MetaMask), ecosystem utilities and the ozonescan.com explorer LAYER 4 Execution · EVM Solidity smart contracts, Ethereum JSON-RPC, 0x addresses, Hardhat and Remix tooling LAYER 3 Application · Cosmos SDK Modules for bank (OZONE transfers), staking, distribution, slashing and governance LAYER 2 Consensus · CometBFT Delegated Proof-of-Stake validators, BFT voting, finality in one block LAYER 1 Network · P2P Peer-to-peer gossip between validator and full nodes over TCP/IP VALIDATORS AND FULL NODES 100+ NODES

Instant finality

Committed blocks are final; no reorganisations.

Ethereum tooling

Solidity, MetaMask and JSON- RPC work unchanged.

Modular upgrades

Each layer evolves through onchain governance.

The five layers in detail

3.1 · LAYER 1

Network Validator and full nodes exchange transactions and blocks over a peer-topeer gossip protocol. Any party can run a full node and verify the whole chain independently, without trusting a third party.

3.2 · LAYER 2

Consensus (CometBFT) CometBFT is a Byzantine Fault Tolerant engine. Validators propose and vote on each block in rounds; a block commits once validators holding more than twothirds of voting power sign it. A committed block is final and cannot be reorganised.

3.3 · LAYER 3

Application (Cosmos SDK) The state machine is built with the Cosmos SDK, a modular framework used by many production blockchains.

Its modules run OZONE transfers (bank), staking, reward distribution, slashing and on-chain governance.

3.4 · LAYER 4

Execution (EVM) An EVM module executes Ethereum smart contracts inside the Cosmos SDK application. Solidity contracts deploy unchanged through the standard JSON- RPC interface; MetaMask, Hardhat and Remix work out of the box with familiar 0x addresses.

3.5 · LAYER 5

Applications Where users meet the chain: wallets, payment apps, games, marketplaces, enterprise tools and the ozonescan.com explorer. Every application settles in OZONE and inherits the security and finality of the four layers beneath it.

3.6 · FEES

Paid in OZONE Every transaction pays a gas fee in OZONE. Fees go to validators and delegators through the distribution module, rewarding the operators who secure the network. Current gas price:

0.01 Gwei.

Consensus, validators and staking Ozone Chain is secured by validators who stake OZONE and can lose part of that stake if they misbehave.

4.1 Validators

Ozone Chain is a public network: anyone who meets the minimum self-bond of OZONE can run a validator. More than 100 nodes, validators and full nodes together, run the network.

Voting power equals a validator's own stake plus OZONE delegated to it.

100+ Nodes running the network 74 Validators in the latest 2,000 blocks 5.9% Share of the most active validator 47% Share of the ten most active Block production measured on ozonescan.com, 21 October 2026. No single operator or small group controls the chain.

4.2 Delegation

Holders who do not run a node can delegate OZONE to a validator.

Delegated coins stay owned by the delegator; they add to the validator's voting power and earn a share of its fees, minus commission.

4.3 Rewards

Validators and delegators earn the transaction fees paid on Ozone Chain, in OZONE, in proportion to their stake and uptime. Fees are distributed automatically every block.

4.4 Slashing

Double-signing: a share of stake is slashed and the validator is removed.

Extended downtime: a smaller share is slashed and the validator is jailed.

Penalties also apply to delegations.

4.5 Unbonding

Staked OZONE is released after an unbonding period. During this period the coins earn no rewards and can still be slashed for earlier misbehaviour.

On-chain governance Changes to Ozone Chain's parameters and software are decided by OZONE stakers through on-chain votes, operating as a DAO.

What the DAO decides

Network parameters Chain software upgrades Monthly allocation releases Spending from community funds

How a proposal moves

1 Proposal Any OZONE holder submits a proposal with a deposit.

2 Deposit period The proposal enters voting once it reaches the minimum deposit.

3 Voting period Staked OZONE votes Yes, No, No with veto or Abstain; delegators vote directly or inherit their validator's vote.

4 Tally A proposal passes when it meets quorum and the passing threshold.

5 Execution Parameter changes apply automatically; upgrades activate at the block height named in the proposal.

DAO

The majority of staked OZONE and of validator nodes is held by the community, not the founding team. Because voting power comes from staked OZONE, the public that secures the network is the public that steers it.

OZONE token OZONE has a hard cap of 50,000,000 coins; 95% is reserved for ecosystem rewards and only 2% goes to the team.

6.1 Utility

Gas

Pays for every transaction and contract call.

Staking

Validators and delegators stake it to secure the network.

Governance

Staked OZONE is voting power in proposals.

Payments

Ecosystem applications accept and settle in it.

6.2 Supply

50,000,000 Maximum supply, can never increase 50,000 Initial supply at launch Deflationary Supply only shrinks through burning

6.3 Distribution

Allocation Share OZONERelease Ecosystem Rewards 95% 47,500,000Through the NFTWall program Team 2% 1,000,000Monthly over 10 years, DAO-approved Liquidity 1% 500,000Monthly over 10 years, DAO-approved Research & Development 1% 500,000Monthly over 10 years, DAO-approved Server Infrastructure 1% 500,000Monthly over 10 years, DAO-approved Total 100% 50,000,000

6.4 Treasury and release schedule

95% Ecosystem Rewards Held in a treasury contract and distributed to participants through the NFTWall program (nftwall.io).

5% Team, Liquidity, R&D, Server Released in monthly instalments over 10 years (120 months). Each release is approved by the DAO.

Every allocation has its own wallet, published on ozonechain.com and trackable on ozonescan.com, so the community controls how fast coins reach the market.

6.5 Burning

OZONE is burned by sending it to an unspendable address. Burned coins leave supply permanently; every burn is an on-chain transaction anyone can verify, and the cumulative burned amount is reported live.

BURN ADDRESS 0x000000000000000000000000000000000000dEaD

6.6 Supply transparency

Supply figures are calculated from on-chain balances and published through public endpoints used by ozonechain.com and by market-data providers such as CoinMarketCap and CoinGecko.

Security

Security rests on BFT consensus, economic penalties, independent audits and public verifiability.

Consensus safety

Safe while less than one-third of voting power is faulty. Committed blocks are final.

Economic security

Validators and delegators stake their own OZONE; slashing makes attacks costly.

Smart-contract audits

NFTWall contracts are audited by SolidProof, with periodic third-party reviews.

Verified contracts

Treasury and core contracts are sourceverified on ozonescan.com.

Open verification

Every block, balance, burn and release is public; anyone can run a full node.

Key management

Users hold their own keys; applications are non-custodial by default.

Risk factors

Technology. Bugs, consensus failures or outages could interrupt the chain.

Upstream software. Defects in Cosmos SDK, CometBFT or EVM components may affect the network until patched.

Smart contracts. Applications run their own contracts, which may hold vulnerabilities even after audit.

Validator concentration. Concentrated voting power raises collusion and outage risk.

Market and liquidity. OZONE trades on few exchanges; price can be volatile and liquidity thin.

Regulation. Digital-asset laws differ by country and may restrict access in some regions.

Key management. Lost or stolen private keys cannot be recovered by the network.

Execution. Roadmap applications may launch later, change scope or not launch.
