[ANN] Ethernova (NOVA) | PoW EVM L1 | State Expiry, Native AA & ZK Privacy

[Ethernova]

Next time dont copy old projects mate and all will be fine.
https://github.com/RitabrataDas343/Ethernova

Mate, that repo has zero connection to us. None of us even knew it existed when we chose the name — it’s just a coincidence.

We’re Ethernova Chain: a completely independent chain with our own code, our own vision, and our own mission — a supernova of the Ethereum spirit after Ethereum killed PoW with the Merge (Sep 15, 2022).

Ethernova Chain babyyyyyyyyyyyy.

Is everything back up and running now?? I have moved on to another GPU project, but may come back, if all good now

[Ethernova]

Everything is normal now. I will post a resume of what happened tomorrow here.

[ANN] Ethernova Network Incident & Recovery – Chain Split Resolved

This post documents a network incident that occurred during a failed hard fork attempt and explains how the network was fully recovered and stabilized.

⸻

What happened

The incident was triggered by an attempted hard fork intended to change the chain ID:

• Old chain ID: 77777
• Target chain ID: 121525

The hard fork did not complete correctly and caused the network to split into two parallel chains:

• One continuing on chainId 77777
• One starting on chainId 121525

This resulted in a temporary network partition (multiverse).

⸻

How it was detected

A third party (Gatevia) reported inconsistent balances and node behavior.
Investigation confirmed the existence of two independent chains with different genesis states.

⸻

Root cause

• The legacy chain (77777) contained the real mining history
• The forked chain (121525) had an incorrect genesis and impossible balances
• This was a protocol-level split, not an explorer or UI issue

⸻

Resolution strategy

Instead of patching a broken state, the following clean recovery was executed:

• The 77777 chain was declared the source of truth
• A full snapshot of real balances was taken
• A new final genesis was generated for chainId 121525
• All wallets were preserved exactly as they existed
• Total supply was fully verified against mining history

Final verified values:

• Final genesis hash: 0xc3812e…
• Total supply: ~1,765,151.5625 NOVA

⸻

Security hardening

To prevent this from ever happening again:

• Nodes now hard-lock the expected genesis hash
• Startup fails immediately if the datadir genesis is wrong
• Wrong or tampered chains cannot start
• Single-universe consensus is enforced

⸻

v1.2.7 Release

• Clean rebuild on chainId 121525
• Windows & Linux full binaries
• SHA256 checksums published
• Anti-multiverse protections active

⸻

Infrastructure status

• RPC nodes upgraded and stable (no mining enabled)
• Explorer fully realigned and showing correct balances
• Mining pool upgraded and operational
• External miners can mine normally

⸻

Current status

✔ One unified chain
✔ Correct balances
✔ Stable RPC
✔ Healthy explorer
✔ Mining pool online

⸻

Transparency

This post is published to maintain a public record of what happened and how it was fixed.

No balances were erased.
No hidden reallocations occurred.
All data comes from verifiable historical state.

⸻

Ethernova is now stable, unified, and protected against future chain splits.

🛠️ Ethernova Core Update: v1.3.1 🛠️
Hello everyone! A new maintenance update for the Ethernova network is now available.

What's changed in this release?

• Sync Fix: Resolves an issue where new nodes syncing from block 0 would fail at block 3,986 due to a legacy chain ID mismatch. We implemented a dualSigner to handle historical transactions smoothly.
  
• Network Updates: Updated VPS boot nodes with correct listening ports (30303/30304).
  
• Easier Setup: Added a pre-configured config.toml with static peers for a zero-config startup.

🚀 Attention Ethernova Community! Official Protocol Update 🚀

It’s been an intense week of building, coding, and evolving. Recently, we had some deep technical discussions regarding how Ethernova shouldn't just be another Ethereum clone, but a superior, self-optimizing network.

Today, I am thrilled to officially announce that Ethernova Devnet 1.0.0 is live and in active testing! 🌐⚒️

Right now, it is a Closed Devnet. We are running extreme stress tests across our 4-node ESXi infrastructure to validate consensus and security, but I want to share the massive technical milestones we’ve already implemented:

🔥 Under the hood of the new Ethernova Engine:

• ⛽ Adaptive Gas: We are rewarding efficient code. The protocol now applies a 25% gas discount for optimized/predictable execution patterns, and a 10% penalty for complex, non-parallelizable workloads.
• ⚡ Execution Modes: We are moving beyond static execution. We've built a Standard mode, a Fast mode (skipping redundant checks), and a Parallel mode (conservative speculative execution for simple transfers).
• 🧠 Runtime Optimization: Nodes now dynamically analyze bytecode at deploy time and cache results for pure contract calls. The network literally learns to process faster.
• 🏗️ Full Infrastructure Built: We already deployed our own Blockscout Devnet explorer, a Faucet, CI/CD pipelines, and a real-time web UI Dashboard.

Our Core Principles: Determinism first and Devnet before Mainnet. We will not push any of this to the public Mainnet until we guarantee 100% consensus safety across all nodes under heavy loads.

Ethernova is evolving from a standard EVM chain into a self-optimizing execution environment, while staying true to our PoW mining core.

Keep mining, stay tuned, and I'll let you know as soon as we open the public RPC endpoints for developers to come and try to break it! 💎⛏️

[Ethernova]

🚨 THE ETHERNOVA PUBLIC DEVNET IS OFFICIALLY LIVE! 🚨

The wait is over. After rigorous internal stress testing on our local ESXi clusters (passing 47/47 core tests with 0 consensus errors), the Ethernova Adaptive EVM Devnet is now open to the public! 🌐⚒️

This is the testing ground for the upcoming Noven Fork, where we are fundamentally evolving how the EVM works. We are moving away from static gas costs and introducing a smart, self-optimizing Layer 1 protocol.

🔥 What’s live on the Devnet right now?

• ⛽ Adaptive Gas Economy: Write efficient code, pay less. The network automatically gives a 25% gas discount to contracts with pure computational patterns, and applies a 10% penalty to storage-heavy spam.
• ⚡ Execution Modes & Parallelism: We’ve enabled conservative Parallel Execution for simple transfers and a "Fast Mode" that skips redundant checks.
• 🛠️ Custom Precompiles: We built novaBatchHash (0x20) and novaBatchVerify (0x21) directly into the protocol to make MultiSig and batch operations mathematically cheaper and faster than standard Ethereum.
• 🧠 Runtime Optimization: The EVM now analyzes your bytecode, caches pure calls, and optimizes redundant opcodes on the fly.

🌟 ETHERNOVA v2.0.0 — THE NOVEN FORK 🌟
A smarter Ethereum. Same compatibility. Better economics.

🔗 Noven Fork activates at mainnet block 480,000
All nodes must upgrade before then. Named after community developer Noven who built the adaptive gas system.

📈 Live countdown & stats: https://ethnova.net/stats.html


🚀 WHAT'S NEW IN v2.0.0?

⛽ Adaptive Gas V2
Smart contracts are now classified by what they actually execute, not what their bytecode contains:

• Pure computation (math, hashing) → up to -25% gas discount
• Light operations (reads, views) → up to -15% gas discount
• Mixed operations → no change
• Heavy storage (DEX swaps, 7+ SSTOREs) → up to +10% gas penalty

100% deterministic. Pure integer math. Same transaction = same adjustment on every node. No floats, no randomness.

🛡️ Native Reentrancy Protection
The #1 DeFi exploit vector (DAO hack, Curve exploit, $2B+ lost) is now blocked at the protocol level. The EVM itself prevents a contract from calling itself while already executing. No more ReentrancyGuard modifiers needed. Cross-contract calls (A→B→C) work normally.

💸 Gas Refund on Revert
On Ethereum, failed transactions cost you full gas. On Ethernova, simple reverts get 90% of execution gas refunded. Anti-DoS protected: only applies to transactions under 100k execution gas.

📦 9 Native Precompiles (0x20-0x28)
Protocol-level operations that would be expensive or impossible as smart contracts:

Address	Name	What it does
0x20	novaBatchHash	Batch keccak256 hashing — 30 gas/item
0x21	novaBatchVerify	Batch ecrecover — verify multiple signatures at once
0x22	novaAccountManager	Native key rotation + guardian recovery for wallets
0x23	novaFrameApprove	Frame-style account abstraction approval
0x24	novaFrameIntrospect	Cross-frame transaction inspection
0x25	novaTokenManager	Create and transfer native multi-tokens
0x26	novaShieldedPool	Optional privacy — shield/unshield NOVA
0x27	novaContractUpgrade	Native contract upgrades with 100-block timelock
0x28	novaOracle	Protocol-level price feeds with TWAP

♻️ State Expiry
The blockchain garbage collector. Contracts with no activity for ~115 days (900,000 blocks) are automatically archived. EOA wallets are NEVER expired. Archived state can be restored with a Merkle proof. This solves Ethereum's #1 scalability problem: unbounded state growth.

⚡ Tempo Transactions
Batch multiple operations into a single atomic transaction:

• Atomic batching — approve + swap in one tx (both succeed or both revert)
• Fee delegation — someone else pays your gas
• Scheduled execution — execute at a future block
• Up to 16 calls per batch, all-or-nothing execution

🔒 Anti-MEV Fair Ordering
Transactions ordered by arrival time (FIFO), not by gas price bidding. Rate limiting prevents spam flooding. No sandwich attacks. No front-running. Fair for every user.


📊 ETHERNOVA vs ETHEREUM

Feature	Ethereum	Ethernova 2.0
Gas pricing	Flat — same cost regardless	Adaptive: -25% discount to +10% penalty
Reentrancy protection	None (devs add their own)	Built-in at protocol level
Failed tx cost	Pay full gas	90% refund on revert
Account abstraction	ERC-4337 + external bundlers	Native Frame AA
State management	Grows forever (200GB+)	Auto-archive after ~115 days
Batch operations	One operation per tx	Up to 16 atomic calls
MEV protection	None ($600M+ extracted)	FIFO fair ordering
Oracle support	External only (Chainlink)	Native precompile with TWAP
Contract upgrades	Proxy pattern (complex)	Native timelock upgrades
Precompiles	9 (standard)	18 (9 standard + 9 Ethernova)

🔧 TECHNICAL DETAILS

• Chain ID: 121525 (0x1DAB5)
• Consensus: Ethash PoW
• Block time: ~11 seconds
• Block reward: 10 NOVA (halving every ~2.1M blocks)
• EIP-1559: Active from genesis
• Noven Fork block: 480,000
• Files changed: 40 files, 7,675 lines of new code
• Unit tests: 53/53 passing
• Consensus bugs caught on devnet: 5 (all fixed before mainnet)
• Block hashes verified identical: blocks 1 through 445,000
• Genesis hash preserved: 0xc3812eb81498965a...

⬆️ HOW TO UPGRADE

1. Download the binary for your platform from GitHub Releases
2. Replace your current ethernova binary
3. Restart your node
4. Done. No re-init. No data migration. No chain reset.

⚠️ All nodes MUST upgrade to v2.0.0 BEFORE block 480,000 or they will stop syncing.

100% backwards compatible. All existing contracts, tools, and wallets work without changes. MetaMask, Hardhat, Foundry, ethers.js — everything just works.

🚀 Ethernova v3.0.0 — NIP-0004 Mainnet Fork Announcement 🌌

Ethernova is preparing for the NIP-0004 mainnet fork.

Activation Block:
853,400

NIP-0004 is the Layered Deterministic Computer upgrade.
It expands Ethernova from a standard EVM / POW blockchain into a protocol-native app layer for identity, messaging, content, sessions, and deterministic on-chain objects.

✨ What NIP-0004 Adds

🧱 Protocol Objects
Native chain-level objects for content, mailboxes, sessions, identity, and future app primitives.

⏳ Deferred Execution
A deterministic queue system for actions that can be processed safely across blocks.

🗂 Content References
On-chain references for off-chain content with lookup, verification, pagination, rent, and expiry behavior.

📬 Mailbox Primitive
Native mailbox and message infrastructure for protocol-level communication.

♻️ State Lifecycle
Active / Warm / Cold / Archived state tiers to support long-term chain sustainability.

🛡 Execution Domains & Capabilities
A safety model that separates normal EVM contracts from Nova-native contracts and restricts access to advanced protocol features.

🔗 Sessions / Channels
Bilateral session primitives for off-chain state exchange with on-chain settlement and dispute support.

⚙️ Multi-Dimensional Resource Metering
A better resource model that tracks different workload types instead of treating everything as one simple gas number.

🧩 App Precompiles + Nova Opcodes
Native tools for future apps, chat, content ownership, identity, games, and real-time interaction.

🔥 Why This Matters

NIP-0004 lays the foundation for protocol-native applications directly on a POW-secured, EVM-compatible chain.

This is a mandatory hard-fork upgrade.

Node operators must upgrade before block 853,400.
Nodes that do not upgrade will fall out of consensus after activation.

📦 Release
https://github.com/EthernovaDev/ethernova-coregeth/releases/tag/v3.0.0

Ethernova v3.0.0 is the foundation for the next era of Nova. 🌌
