NEO3

  • Discussed the worked on the design of cross-chain mechanism.

  • Finished internal review and audit of NEO3 white paper.

  • Worked on the developer guide - 80% complete.

  • Implemented functionalities for C# SDK, working closely with Core Developers on detailed implementation - 20% complete,

  • Worked on designing the NEO3 voting mechanism and the corresponding incentive mechanism, choosing the preferred algorithm and technical architecture - 50% complete.

  • Finished unit tests for over 240 methods.

NEO2
  • Collaborated with the community on fixing major bugs for MainNet, and testing the corresponding fix on TestNet.

General
  • Website updates: Developed and published new EcoBoost page, new developer page, and technical docs.

Events
  • July 19th - 21st: NEO was invited to participate in the DoraHacks hackathon - "The Fourth Industrial Revolution." NEO founder and core developer, Erik Zhang, delivered a speech titled "Blockchain will change the future of the internet,” in which he discussed the architecture of the next generation internet and his vision of NEO3. During the three-day geek feast, three engineers from NGD helped hackers learn more about NEO technology.

  • July 25th, Head of EG development, John Wang, delivered a speech at the Cointime Summit 2019 held in Vietnam.

  • July 25th, The NEO Powers Up Vietnam meetup took place with over 60 NEO fans attending the event. John Wang and head of NGD marketing development, Gao Yuan, spoke about the direction and progress of NEO, and answered questions from the local community regarding EcoBoost.

Other Progress:
  • NEO announced a new joint initiative with Ontology to build an interoperable cross-platform protocol to establish the foundation of the next-gen Internet. The protocol will feature an eco-friendly approach to member chains, a low barrier to entry for integration, transactional atomicity, and enhanced security.

  • More than 50 major EcoBoost partners were announced across six categories: liquidity, wallets, media, channels, community, and security. The EcoBoost program has now moved onto phase two, which will focus on supporting entities building in the NEO ecosystem. Interested projects are welcome to visit neo.org/ecoboost or contact us at eg@neo.org to join the NEO EcoBoost program.
Available positions

NGD Seattle Progress
  • Smart Contract Debugging

NEO Smart Contracts now have a first-class debugging experience for C# inside Visual Studio Code, and the bits are available for feedback. Contact seattle@ngd.neo.org if you want to work with the early access bits. This work is foundational for full debugging for multiple languages (C#, TypeScript, Python, Java etc.) across multiple platforms (Windows, Mac, Linux).

  • NEON vNext

Compiler enhancements and extended extensibility in progress; short-term re-developed debug data to enable location of symbols and to relate current execution state of the source code. This addresses the need to save time and to gain insight as part of the F5 Developer Experience.

  • NEO-FX (the new Unified Programming Model)

The NEO-FX Unified Programming Model (spanning on-chain, off-chain, and the plug-in developer experience) Design Note DRAFT will be available at the end of July for early feedback from the community.

  • NEO Design Notes

NGD Seattle is using the Design Note approach, as pioneered by Microsoft Research to address gaps in the open source development process, focusing on engineering excellence.

  • Decentralized Identity Foundation

NEO joined the Decentralized Identity Foundation (https://identity.foundation/) towards the goal of establishing an open ecosystem of decentralized identity. 

Developer Community Progress

NEO Saint Petersburg Competence Centre

  • “Summer school on practice and theory of distributed computing” attended by Leonard Liubich and Vsevolod Brekelov: https://sptdc.ru/

  • NeoFS Introduction Video (Episode 1: System Overview): https://www.youtube.com/watch?v=RhaGFODl4_E

  • New team members recruited for neo-go development:

    • Vsevolod Brekelov, M.Sc. in Applied Mathematics and Informatics (Saint Petersburg State University), former software engineer at Grid Dynamics and Google, QA automation engineer at Raymond James

    • Roman Khimov, M.Sc. in Computer Science (ITMO University), former team lead at Kraftway Corporation PLC, head of networking equipment department at ALTELL Ltd.

COZ
Neo-python
  • Continued TestNet audit comparing neo-python results to neo-cli 2.10.2 on state (VM engine, VM result, storage), fees (net, sys, GAS consumption) and transaction details. 17 PR's were made this month fixing various issues encountered during the audit, including porting the whole data caching layer from neo-cli. The audit is currently at 93% completion for TestNet. 

  • Collaborated with NeoResearch on a cross language BigInteger library (with Python wrapper) as the previously mentioned audit has taught us that different languages handle certain features of BigIntegers differently (Python being one of those languages). This can potentially benefit all other languages implementing NEO3.
