NKN Releases V0.7 Meerkat

NKN was excited to announce the early release of v0.7 Meerkat on January 18th, 2 weeks ahead of schedule. Meerkat is the final testnet release and marks a significant milestone for the NKN project. The release includes a full featured testnet with complete implementation, strong security and enhanced performance, and a SDK.

Release Highlights:

  • MOCA Consensus module was re-written for better security against attacks as well as greater improved stability
  • Enhanced network layer which includes resistance to malicious and spam messaging, 70x more efficient block/transaction broadcasting, and latency-based proximity routing to achieve up to 100% faster relay messaging
  • Block synchronization module rewritten to include local BFT-level robustness against malicious and faulty neighbors as well as a 10x faster block synchronization
  • New Pub/sub feature used to discover and subscribe to useful application services running on top of the NKN platform
  • New Golang SDK with both client and wallet implementation
  • Our GitHub stats shows the substantial amount of work done for Meerkat: 128 files have changed, 12,451 lines of new code were written, replacing 7,208 lines of old code.

For more details on what is included in v0.7 Meerkat, check out our blog post:


We have also released three subsequent bug-fix and performance enhancing sub-releases. The newest version v0.7.3-alpha has quite a few significant improvements:

  1. Memory usage is greatly reduced (<200–300MB) and will not grow over time, so it can be run stability on smaller and cheaper devices with less resources.
  2. Bandwidth usage is further reduced by 50% ~ 80% so it saves you money!
  3. Automatic fork detection and rollback, to avoid chain re-sync in most cases.

The latest new and stable version is here: https://github.com/nknorg/nkn/releases

Github source code development progress

NKN testnet code development progress over the last two weeks is mainly reflected in nkn, nnet, nkn-sdk-go, nkn-client-js, nkn-wallet-js, nkn-mining repositories and different branches. There is a significant surge due to the merge of new consensus implementation and many other improvements from Meerkat.

The latest stable release: v0.7.3 was released on January 18th, 2019.

NEP-5 to ERC-20 token swap updates

Here is the latest token swap stats as of January 28th, 2018: so far 210,542,291 tokens have been swapped from NEP-5 to ERC-20, which represents about 60% of total circulating supply (350M). We are working with our existing exchanges to push that number towards 75%. So we encourage you to swap your tokens for better liquidity in the future.

The token swap program that was announced on January 3rd continues as our community has begun swapping their NEP-5 tokens to ERC-20 based tokens. This voluntary program is being offered to enable improved liquidity as well as leverage the large ecosystem built by Ethereum. If you haven’t done so already, please swap your tokens today!

If your tokens are on gate.io, your tokens will be swapped automatically on their respective platforms. Official announcement from gate.io can be found here: https://www.gate.io/article/16733

For all others, NKN is offering an official NKN web-based tool to swap your NEP-5 tokens for ERC-20 tokens at https://swap.nkn.org/.

For instructions and more information check out our medium posts and YouTube video to assist you with your token swap:

Public testnet organically grows to more than 5,000 nodes

NKN public testnet map

NKN public testnet country list

NKN’s public testnet has grown to over 5,000 nodes across more than 40 different countries. This a significant achievement in no small part to the strong support from our community. Of these nodes, only 114 are being seeded by NKN. The remainder are being hosted by our community.

What makes this even more special is the fact that NKN is more decentralized than ever before. Back in November 2018, we had reached a similar milestone with the help of big miners in our community that were running 1,000+ nodes at a time in datacenters. However, this time, we have more community members running nodes across a great number of countries than ever before.

We sincerely thank everyone who is running NKN nodes in our testnet and helping our project build one of the largest public blockchain networks available anywhere (only behind Bitcoin and Ethereum at the moment).



Community developers upgrade nknX.org to v0.3.0
