Vision

Bringing back the golden age of profitable, community-driven GPU mining - and powering it with a full EVM ecosystem.

EVM Ecosystem

Build NFTs, tokens (ERC-20 style), DeFi apps (DEX, liquidity, farming, lending), and smart contracts on a miner-first chain.

Community First

NOVA is focused on miners and builders who want transparency, predictable economics, and a chain that values GPU accessibility.

What is Ethernova?

Ethernova is CoreGeth-based, fully EVM-compatible, and mining friendly with excellent Windows support.

It is engineered for stable mining operations, rapid onboarding for developers, and a community-driven network secured by GPUs.

Mainnet Upgrade (v1.2.7, No Chain Reset)

Upgrade with the v1.2.7 scripts below. Do not reset your chain.

What's new in v1.2.7

  • Chain ID / Network ID updated to 121525 for mainnet.
  • Network stats supply now includes the legacy migration baseline.
  • Ethash epoch and DAG size info added to Network Stats.

Warning: Do NOT replace the genesis inside your datadir. Init updates the stored chain config while preserving the genesis hash.

Roadmap

Short, focused milestones to harden the chain and grow the ecosystem.

Phase 1: Stabilize

Expand public nodes, harden P2P connectivity, and onboard more pool operators.

Phase 2: Builders

Launch docs, tooling, and starter smart contracts for DeFi and NFT builders.

Phase 3: Growth

Scale infrastructure, launch community grants, and push multi-region redundancy.

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 GPU 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.
