Two 90s kids won the Weekly Champion prize with their submission of a NAS Red Envelope DApp
Out of the 231 DApps submitted to NIP last week, the top prize was awarded to a NAS Red Envelope DApp that mimics the functionality of red envelopes (or red packets) in Alipay and WeChat. As we understand, this DApp was developed in just 10 days by a team of two people born in the mid-1990s. Congratulations to our Week 1 Champions for their creative app and winning the 10,000 NAS reward!
Nebulas and CertiK announced a strategic partnership at Consensus 2018
Nebulas, the startup incubator of the next generation public blockchain Nebulas, and CertiK, a formal verification framework to ensure smart contract and blockchain security, announced a strategic partnership at the Consensus 2018 conference in New York City. CertiK offers a formal verification framework to mathematically prove that smart contracts and blockchain ecosystems are bug-free and hacker-resistant. As part of this partnership, CertiK will provide technology to Nebulas to ensure DApps and smart contracts on the blockchain ecosystem are secure, reliable and resistant to hacking. Thanks to Certik’s technology, developers on Nebulas will be able to receive real-time and interactive verification feedback when building DApps and smart contracts, helping to free up time and effort previously spent on debugging and auditing code.
Recap of Nebulas at Consensus 2018 and the NAS Night cocktail party
Consensus, the global blockchain conference hosted by Coindesk, was held in New York City from May 14th to May 16th. Nebulas was one of the sponsors of the event, which gathered more than 250 speakers and 4,000 participants. Nebulas co-founder Robin Zhong attended the event, accompanying members of the Nebulas tech and business teams, and Nebulas community members from San Francisco, New York, Boston and Salt Lake City. Nebulas had a standalone conference room at Consensus to introduce our project to the public and discuss potential cooperation initiatives with blockchain practitioners from around the world.
We also hosted a cocktail party on the evening of the 15th to thank the community for their long-term support, and to promote communication among developers, investors, and enthusiasts of Nebulas. Altogether, Consensus was a great time and allowed us to showcase our technology and vision to some of the top people in the blockchain space. Many also expressed their intent to participate in our Nebulas Incentive Program.
Hitters Xu hosts a private get together for xGooglers at the Nebulas office in Beijing
On May 18th, the GBA (xGoogler Blockchain Alliance) held an intimate meetup at the Nebulas office in Beijing. A group of former Google engineers who are now work in blockchain, or intend to move into this space, came together for the event. Nebulas founder, and former Google engineer, Hitters Xu shared his experience as a blockchain entrepreneur and his philosophy for “thinking in blockchain” with guests. Hitters also explained the Nebulas Incentive Program as an initiative to kickstart a thriving DApp ecosystem. The atmosphere was lively and gregarious.

NAS Center hosts a DApp development workshop hosted by a Nebulas community member
On May 19th, Nebulas community developer Brandon co-organized developer workshops and hackathons with the Nebulas team at the NAS Center in San Francisco. The event aimed to give guidance on how to develop a DApp on Nebulas, to enable participants to win rewards on the Nebulas Incentive Program. The event began with an explanation of the process of developing a DApp on the Nebulas mainnet, with the remainder of the event being dedicated to actual DApp development.
Around 40 local engineers attended the event. Brandon got in touch with a local club of JavaScript developers, and these club members made up a large portion of the attendees. Those who participated in the event said they learned a lot. One engineer did not leave until 8PM, and he said he would recommend the Nebulas Incentive Program to all engineers he knew.
Because of the positive response of the event, Brandon plans to hold development workshops on a regular basis. Every Tuesday, workshops centering on the Nebulas Incentive Program will be held at the NAS Center.
LAST WEEK’S Top Commits
Mainnet Development Progress
Go-nebulas 1.1.0 has been tested for some time, and is nearly ready to be released.
Call between contracts
Multiple code reviews have been done for making APIs for calling between contracts more semantically concise and user-friendly. We also continued to test the function from four aspects: functionality, performance, stability and security.
Persistent Cache
To provide a more reliable data cache, we designed a new persistent component for data cache and development is done. Testing is now about to start.
Nebulas Incentive
We received over 800 DApps in the first week of Nebulas Incentive and more than 290 developers and referrers got rewarded. The competition for NAS rewards is sure to get more intense as the Incentive Program continues and the quality of submitted DApps improves.
In addition, we released a DAppBoard
