Mainnet Release: Feature Highlights and Upgrade Guide

On July 1st, NKN launched Mainnet v1.0 narwhal release and to date nearly 26K+ full nodes are running globally. Thank you to our development team and our community for making this such a great success.

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 9: you can now run full node in one line

For more detailed information about how to build, configure, and run a node, please see the latest github readme at https://github.com/nknorg/nkn

If you are running one-click miner on DigitalOcean, AWS or Google Cloud, you just need to grab a drink and restart your one-click miner machine, and the rest will be automatic.

IoTalks Interview with Bruce Li and Allen Dixon

On July 12th, NKN’s partner IoTex launched their latest episode of IoTalks featuring NKN Co-Founder, Bruce Li, and VP Business Development, Allen Dixon. This interview covers the past, present, and future of connectivity and we also share some insights from NKN and our new nCDN and secure messaging services as well as emerging connectivity technologies like 5G and LoRaWAN emerging. Check out the full episode here.

Along with the IoTalks episode, NKN and IoTex are launching an IoTalks campaign. Tell us your best blockchain+IoT+connectivity use case and you could be a winner. To participate, follow the introductions in the post below.

1-click NKN node image updated for mainnet on 3 cloud platforms

Our 1-click NKN node image has now been updated for mainnet and approved by all three leading cloud platforms DigitalOcean, Google Cloud Platform, and Amazon Web Service. Some of the highlights of this version:

Upgraded for Mainnet

• Improved security: mandate one unique wallet per node. it is no longer possible to take a snapshot of one running node and clone.
• Promote BeneficiaryAddr to further improve security: so the mining reward can be kept in secure wallet that is generated by user personally and not stored anywhere on the cloud.
• Reduced resource usage: especially network bandwidth usage is reduced by at least 50%, since it is a major cost factor for some cloud platforms. Also reduced requirements on CPU and memory.

Of course we kept all the features and benefits our miners enjoy from testnet v0.8.x: health monitoring and auto healing, remote node status information, and etc. Currently we still support auto-upgrade during phase 1 of Mainnet for faster bug fix and network upgrade.

Mining Bonus Address

With the launch of Mainnet v1.0 narwhal, we also introduced a Mining Bonus Address (MBA) that will be used to provide additional mining rewards to NKN miners. The MBA is a special NKN wallet address that can be used to transfer tokens in, but not take tokens out, similar to a deposit-only account. All the initial tokens mined from June 29th-July 1st have been added to MBA, and you are welcome to donate tokens to the address as well. Any tokens transferred into MBA will be added to extra mining rewards starting from the next mining year (1,576,800 blocks), with each year releasing half of the tokens remaining.

Mining Bonus Address and Why Mainnet started before July’1?:

Mining Bonus Address and Why Mainnet started before July’1?

You might have noticed that NKN’s Mainnet has started the genesis block already at 13:10:13 UTC on June 29th, 2019. The main reason is to ensure a smooth Mainnet launch at 04:00:00 UTC on July 1st, 2019, so we started the bootstrap process a day and a half earlier. The seed nodes on Mainnet are run by NKN project, and will phase out when more community nodes join in the next few days and weeks. So what will happen to the NKN tokens mined during the 40 hours between June 29th and July 1st? These…

nCDN and nanopay: community Q&A

On July 8th, Bruce Li answered community questions about NKN’s nCDN (content delivery) and nanopay (micropayment) services. nCDN will provide content delivery by caching video in multiple nodes for Video On Demand (VoD) or caching segments of video for live streaming across NKN’s network. Nanopay, will provide the payment mechanism for services such as nCDN on our platform. However, while these services were developed to showcase our technology and platform, our community is encouraged to develop their own services that use NKN as well.

Gigamesh’s questions about nCDN, nanoPay, and MBA:

Gigamesh's questions about nCDN, nanoPay, and MBA

GIGAmeshToday at 3:32 PM Will files on nCDN be shared across nodes for redundancy? like IPFS, SIA, STORJ? Have plans for on-chain relay rewards and dapps been sidelined as NKN presses to develop services like nCDN with NanoPay instead? Will NKN have on-chain relay rewards before June 2020? Is the team donating A.) all its mining rewards to MBA, B) Only mining rewards from first 40 hours, or C) not decided yet

NKN and nCDN related questions:

NKN and nCDN related questions

NKN’s blockchain only stores information about what when/where was relayed, not data itself (images, video etc). Correct? So any time an information passes (say video stream) through nodes it doesn’t stop at any point? It just gets relayed over and over and over again (upon demand?)? If that’s the case than how did you solve the latency issue? For example I want to stream high-res (4k?) video and it’s hosted in US and I live in Australia. Let’s say you’ve got 100 000 nodes all over the world, …

The Daily Chain reviews NKN Mainnet

Gigamesh of The Daily Chain reviews NKN’s Narwhal mainnet. Conclusions:

“NKN is now in Phase 1 of its updated roadmap and the focus is on security and stability. NanoPay and the nCDN trials are the big announcements from the Narwhal Mainnet release: a sensible mechanism for making high frequency off-chain payments, and trials for NKN as a decentralized CDN with a tier 1 Chinese provider that have already started. Plans for on-chain relay rewards and dapps have not been sidelined, as Bruce explains “We develop our own flagship product like nCDN to showcase our technology and platform”. NKN is pressing to develop services and harness the power of its 25K node network as quickly as it can.”
