Thanks you for writing this quick rundown! I'm sure it will help others just learning about NAS and why it's so powerful.

One thing I do want to mention is that this article lists Testnet as Q1 of 2018 and Mainnet as Q2-Q3 of 2018. The Testnet is already up and Nebulas is expected to go Mainnet in Q1 of 2018 (max of 8 weeks away). In Q4 of 2018, Nebulas will really start to take shape with Nebulas Rank (NR) and Developer Incentive Protocol (DIP) going active. You can see the roadmap at https://github.com/nebulasio/wiki/blob/master/roadmap.md

For those wanting to take a bit deeper dive, I highly suggest reading the white paper at https://nebulas.io/docs/NebulasTechnicalWhitepaper.pdf

But if that is too much, I wrote up an easy to read overview of the white paper. It's located at https://www.reddit.com/r/nebulas/comments/7rwllx/nebulas_technical_white_paper_review_january_20/

Thanks again!
