NGD Seattle Progress

• NEO Toolkit for VS Code and NEO Express Node progress

NGD Seattle is working on improving the developer experience. It is currently packaging up a NEO Toolkit for VS Code and a NEO Express Node demo, based on the MainNet C# code base, for demonstration at Consensus 2019, New York.

• NEO and Cascadia Blockchain Council

NGD Seattle was invited to be a founding member of the Cascadia Blockchain Council, covering Washington and Oregon in the USA, and British Columbia in Canada. NGD Seattle is also on the steering committee, with a mandate to create and maintain a strong, supportive regulatory environment at the city, state, and federal levels.

Developer Community Progress

NSPCC

• Finalized data audit mechanism based on homomorphic hashing

• Introduced modular setup of components for simple project expansion

• Conducted first tests of simple CLI version of NeoFS nodes

• Finished first end user interface prototype to interact with NeoFS

NeoResearch

• Improvements made to NeoCompiler Eco including:

• The capability to handle and generate multisig addresses, and any other kinds of addresses.

• Capability to submit invocations signed by multiple independent witnesses.

• Capability to run single node consensus in very fast local networks (1 second on average).

• More API for compilers and community usage of the platform.

• General UI improvements.

• Another important step was the start of the neopt project, a portable C++ implementation of the NEO blockchain. This project aims to be a complete rewrite of the C# core project in a very compatible manner, such that fixes will be easily ported between these two projects. This will also serve as a basis for current ongoing projects, such as easily supporting NEO on C++ wallets and integrating NEO with microcontrollers and portable low energy consumption devices. Finally, this project will give the community the capability to easily execute a private NEO blockchain embedded in the user’s browser, a feature that is also intended to be released soon.

COZ

• Neon Wallet:

• Released v2.2.1, featuring the ability to export transaction data from the Activity tab to a CSV file, re-introduction of the ability for Neon to load script hashes via the neo-tokens repo, and various bug fixes.

• Neo-python:

• Ported all updates to the virtual machine to bring it inline with neo-cli 2.10.1 - 2.10.2. Also applied many updates to the ApplicationEngine, statereader and statemachine.

• A branch with new network code (including a switch to asyncio) is running under “public” test and shows very promising performance improvements.

• Initial decoupling of the database layer has happened and is being reviewed. This will allow it to support alternative backends.

• Neon-js:

• Released v4.5.0.

• Redirected all old readthedocs documentation pages to cityofzion.io authoritative documentation site

• Developed JSFiddle examples for most API functions

• Fixed httpsOnly issue

Neow3j

• Claude Müller joined neow3j project as a contributor and member. He's a software engineer at AxLabs and will contribute to neow3j from now on a part-time basis.

• On-going development of classes and convenience methods to interact with Smart Contracts (Invocation Transactions).

• NEP-3 model implemented.

• Pull requests about the JSON-RPC application logs were received, reviewed, and merged to master. Thanks to Nikita Andrejevs (nimmortal at GitHub).
