Narwhal: NKN Mainnet Launch with a Big Splash

After more than 1 year of hard work, today we are thrilled to announce the launch of NKN’s mainnet Narwhal. We set out to build the world’s largest permissionless public blockchain network and achieved this goal at 13,000 full consensus nodes already during testnet and surpassing Bitcoin and Ethereum. Today, we will make it official and intend to scale it to millions if not trillions of nodes so we have a solid foundation to commercialize our flagship products as well as supporting our partner’s applications. More details are here:


NKN Mainnet v1.0-beta

There are tons of new features and improvements introduced in our mainnet version 1.0, as you can see from the change stats (compared to most recent testnet version v0.8.4):

Here is a short list of highlighted features:

  • Change account model from UTXO model to balance model
  • Change signature scheme from ECDSA to Ed25519
  • Implement a secure and verifiable public key infrastructure
  • Use VRF to provide a secure random beacon per block
  • Introduce NanoPay: a simple light-weighted off-chain nano payment channel
  • Signature chain data structure redesigned: reduce 97+% bandwidth overhead
  • Highly optimized block, transaction, sigchain propagation: reduce 80+% overall bandwidth usage
  • Support client-side end to end encryption by default
  • Support node side hop to hop encryption by default
  • Implement connection multiplexing to avoid congestion
  • Store account and other state in verifiable world state
  • Migrate core data structure (e.g. block, transaction) to protobuf
  • Transaction pool redesigned
  • Support multiple native assets
  • Add mining bonus address (MBA) for extra earning reward from donation
  • NKN node image is now hosted on Docker Hub 6: you can now run full node in one line
