Bringing back the golden age of profitable, community-driven POW mining - and powering it with a full EVM ecosystem.
Build NFTs, tokens (ERC-20 style), DeFi apps (DEX, liquidity, farming, lending), and smart contracts on a miner-first chain.
NOVA is focused on miners and builders who want transparency, predictable economics, and a chain that values mining accessibility.
24 phases of protocol-level innovation. Solving Ethereum's biggest problems. Battle-tested on a live devnet. Now live on mainnet (v2.0.0 — Noven Fork at block 480,000).
Anti-Reentrancy built into the EVM. No more DAO hacks, no more Curve exploits. Every contract is protected by default.
Gas Refund on Revert — failed transactions return 90% of gas. On Ethereum you lose everything.
Transactions ordered by arrival time, not gas price. No front-running. No sandwich attacks. Fair for every user.
Rate limiting prevents mempool spam. Miners cannot reorder for profit.
The blockchain garbage collector. Dead contracts automatically archived after 1,000 blocks. Keeps the chain lean forever.
Your wallet is NEVER expired. Only abandoned contracts get cleaned up.
Tokens as protocol objects — no ERC-20 contracts needed. 10x cheaper transfers. No approve+transfer phishing pattern.
Shielded pool for private NOVA transfers. Your choice when to be private. Not forced like Monero. Native in protocol.
Protocol-level price feeds with TWAP. No Chainlink dependency. Circuit breaker blocks manipulation.
Smart Wallets with guardian recovery and key rotation. Lost your keys? Guardians recover your account.
Tempo Transactions — atomic batching (approve + swap in ONE tx), fee delegation (DApps pay gas for you), and scheduled transactions.
Frame AA — smart contract wallets validate transactions. Supports passkeys, multisig, and quantum-resistant signatures.

Short, focused milestones to harden the chain and grow the ecosystem.
24 phases shipped: EVM profiling, adaptive gas, execution modes, state expiry, account abstraction, privacy, native tokens, oracle, anti-MEV, anti-reentrancy. 53/53 tests passed. 5 consensus bugs caught and fixed before mainnet.
All 24 phases activated on mainnet at block 480,000 via the Noven Fork. 7,675 lines of code, 40 files, zero chain reset. Named after community developer Noven who built the adaptive gas system and contributed critical consensus fixes.
DeFi protocols built on native tokens (no ERC-20), privacy-enabled DEX, smart wallet adoption, and cross-chain bridges. The most advanced PoW chain in existence.
Building a mineable EVM ecosystem with real utility - not empty blocks.
Ethernova is a community-driven EVM network built to revive profitable POW mining and expand into a real on-chain economy. The core team focuses on stable infrastructure, mining-first incentives, and simple node operations (especially on Windows) - so builders can ship NFTs, tokens, and DeFi on a chain that actually gets used.
Miners are not an afterthought - they are the heartbeat.
If you can run infrastructure or ship dApps, you are the kind of person this chain was built for.

We are actively seeking public node operators, pool operators, and builders to help bootstrap peers and expand the network.
