Numen v0.2.0

Numen v0.2.0 tightens consensus, validator entry, governance submission, EVM precompile safety, fee calibration, and release reproducibility. It bumps the runtime spec version to 101 and the node package to 0.2.

⚡ What ships

🛡️ Harder PoScan and deterministic difficulty

PoScan now derives generator seeds from the full 32-byte digest, domain-separates the protocol version, pins shortcut-sensitive generation parameters, and binds work hashes to the block pre-hash. Difficulty is verified from the block timestamp inherent instead of the node's local clock, so live import and historical replay reach the same verdict.

🧾 Accountable governance and validator entry

Identity is now part of the runtime. Referendum submission requires a judged identity with a plaintext social channel, and validator entry uses the same qualified identity gate. Public participation is now attributable, not just stake-backed.

🔐 Validator stake

Validator stake remains locked until expiry across exit, pending-queue drops, and stake-exempt paths.

🔐 EVM precompile protections

The native balances ERC20 precompile now rejects delegatecall/callcode access, closing the inherited-caller-context hole.

💸 Fees aligned across Substrate and EVM

Transaction fees now calibrate weight and length pricing against Frontier's EVM gas price. Substrate calls no longer undercut equivalent EVM execution by orders of magnitude, and fee multiplier bounds were retuned around that anchor.

🧱 Runtime migration and weights groundwork

In-house pallets now carry StorageVersion, vesting is wired into the runtime, and benchmarked weights are generated for runtime and local pallets. CI also covers the runtime-benchmarks feature path.

Numen v0.1.0

First public testnet release · 2026-07-19

Numen is a Layer 1 blockchain powered by Proof of Scan, built with the Polkadot SDK.

⚡ What ships

🔭 Proof of Scan that scans 3D objects

Each candidate block defines a new 3D object to scan, and the work is the scan itself. The seal commits to what the scan saw, so grinding nonces means scanning objects, not just hashing headers.

👛 Mining without keys

The block header carries only a payout address, so the miner never holds a private key. Connect an external miner through the RPC endpoints mining_getTask, mining_subscribeTask, and mining_submitSeal, or let the node scan on every core with --node-miner.

🏁 Finality by GRANDPA

Proof of Scan produces blocks while the validator set finalizes them. Sessions rotate keys and im-online heartbeats track liveness. A validator seat requires a 1M NUMN lock over 180 days, with a genesis exemption list so the launch set can bootstrap the network.

🏛️ Governance with no owner key

There is no sudo pallet and there never was one. OpenGov referenda with conviction voting drive every change, a treasury with bounties and child bounties funds the work, and a prime account with only emergency powers for referendum cancel, referendum kill and treasury reject.

⚙️ Full EVM

The Frontier stack is integrated. Deploy Solidity contracts as is, and access the native NUMN balance from Solidity through an ERC20 precompile.

🚀 Run it

wget https://github.com/motoZ-crypto/numen/releases/download/v0.1.0/numen-linux-x86_64.tar.gz
tar -xzf numen-linux-x86_64.tar.gz
cd numen-linux-x86_64
./numen --chain testnet-raw.json

Add mining to the same node

./target/release/numen --chain testnet-raw.json --miner <ADDRESS> --node-miner <THREADS>

Tip

Generate the payout keypair offline, for example with subkey generate, and give the node only the SS58 address. Mining never touches a private key.

What's New

Key Features

  • Implement an on-chain treasury with bounties and child bounties for funding community work.
  • Implement OpenGov governance over treasury and bounty spending, so referenda decide where the funds go.
  • Rework PoW economics with a halving block reward, transaction fees paid to the miner and 10 second target blocks.
  • Add multisig, proxy and utility pallets for shared account control, delegation and batched calls.
  • Export miner-generated 3D models over RPC, so external tools can pull the geometry behind a block.

What's Changed

PoScan

  • Add support for exporting miner-generated 3d model via rpc by @motoZ-crypto in #113
