Title “From the First Public Blockchain in China to Nebulas”. He elaborated on his 6-years blockchain experience in China and Nebulas’ innovative idea. During which, Nebulas was debuted for the first time as “Can’t be evil” at a global summit. We provide an open-source search framework for blockchain world. The search engine based on Nebulas search framework will have three features: open-source algorithms, verifiable computing, and distributed data store. Compared with Google’s “Don’t be evil” is a kind of self-discipline, Nebulas can’t be evil because of these innovative tech features.

As one leader of China’s blockchain technology, Hitters Xu also looked into the future of China’s blockchain.

Touching on the future of blockchain, blockchain for finance, Hitters Xu mentioned that blockchain should not be limited to a regional usage, but instead blockchain organizations and companies should be standardized and on a global scale. In order to grow the business, one will require a comprehensive view. Don’t be afraid of the global regulations, but instead, focus on solving the actual problem in the traditional finance marketing through technology.

New York Tour: building Community, Establishing Relationships and Uncovering Potential Blockchain Projects

Between Nov 6 to Nov 11, the Nebulas team completed its first tour in New York, conducting not only a meetup Columbia University, but also meetings with law firms, VCs, Banks and community parties.

With Nebulas actively seeking for ways to protect everyone’s benefits, communication was established with the top 5 law firms who provide legal services regarding digital assets and blockchain projects in the U.S., such as Perkins Coie and Cooley for potential solutions.

And we also communicated with VCs and Banks such as UBS, Merrill Lynch, JPMorgan Chase Bank, Deloitte, McKinsey, Fortress, Credit Suisse, ConsenSys, Plug & Play.

THIS WEEK’S Top Commits

In the past week, we focused on improving stability and functionality in v0.4.0.

We added execution limits mechanism into the V8 engine, currently we have two types of limits: one is the executed instruction based limits, used for calculating Gas consumption, terminated when Gas drain; the other is CPU/Memory resources based limits, used to prevent massive cpu/memory resources consumption to the host. We also implemented more APIs for RPC and REPL, let developers interact with Nebulas more easily. Besides that, we included Metrics Counter into Nebulas, let system admin or operators can use Grafana liked tools to monitor status of Nebulas.

NVM

  • Implemented Gas calculation mechanism in Transaction based on NVM Execution limits;
