Ethernova mainnet is live

Not another coin site. A people layer for POW.

NOVA brings identity, messaging, content ownership, and builder primitives directly into an Ethhash-secured EVM chain.

Vision

The current devnet is where Ethernova becomes more than an EVM chain: protocol-native identity, content, messaging, and app primitives tested before they touch mainnet.

NIP-0004 Devnet Track

Phase 1 and Phase 2 added Protocol Objects and a deferred execution queue. Phase 3 now adds content references with rent-backed expiry.

Content Ownership Primitive

The devnet now tests deterministic content references: create, lookup, verify, paginate, and expire content ownership records.

Primitive: novaContentRegistrySlot 0x2B

Mailbox Is Next

Phase 4 is the mailbox primitive: on-chain mailbox lifecycle, deferred message delivery, anti-spam rules, and an end-to-end Alice-to-Bob test path.

Nova 2.0 — The Noven Fork

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).

🛡 Native Security

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.

⚖ Anti-MEV

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.

♻ State Expiry

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.

🪙 Native Tokens

Tokens as protocol objects — no ERC-20 contracts needed. 10x cheaper transfers. No approve+transfer phishing pattern.

🔐 Optional Privacy

Shielded pool for private NOVA transfers. Your choice when to be private. Not forced like Monero. Native in protocol.

📊 Native Oracle

Protocol-level price feeds with TWAP. No Chainlink dependency. Circuit breaker blocks manipulation.

Open Technical Deep Dive

📦 Account Abstraction

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.

Leadership

Building a mineable EVM ecosystem with real utility - not empty blocks.

Core Team

Project Lead

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.

We are looking for

  • 🛰️ Node operators (public peers / bootnodes)
  • ⛏️ Pool operators
  • 🧠 Builders (NFTs, tokens, DeFi, tooling)

If you can run infrastructure or ship dApps, you are the kind of person this chain was built for.

Call for Operators

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

FAQ / Troubleshooting

Quick fixes for the most common connection errors.

  • "Could not fetch chain ID" / "RPC error" - Verify the RPC URL exactly and try a different network (Wi-Fi vs mobile data).
  • Wrong Chain ID - Chain ID / Network ID must be 121525.
  • Explorer does not load - Confirm the exact explorer URL is https://explorer.ethnova.net.
