v0.1.0

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.

📇 Chain facts

Consensus	Proof of Scan (PoScan) + GRANDPA finality
ss58 prefix	14240
Token	NUMN (mainnet) · tNUMN (testnet)
Decimals	18
Genesis issuance	600M NUMN (400M treasury + 200M airdrop)
Contracts	EVM via Frontier

🚀 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.
