Neo Global Monthly Report

N3 Launch Edition

Neo N3 has launched. Mass migration of NEO and GAS is safely underway. Now it’s time to build the Smart Economy.

This special edition of the Neo Global Monthly Report focuses on the development progress achieved during July and August which brought us to this momentous time. Further, it documents the Neo N3 readiness of best-in-class support for all the most popular languages, prepared for delivery directly into the hands of developers.


July was a particularly lively month for the Neo ecosystem as hackathon participants made progress on their projects. The Neo Frontier Launchpad had begun in late May, and hackers had until July 12th to submit their concepts. The esteemed panel of judges spent the next week judging the entries, and completed their deliberations on the 20th.

On the same day, the N3 RC4 node version was released, quickly proving itself capable of stable operations within a TestNet setting. This milestone release would later become the formal N3 release, used for the official Neo N3 TestNet.

Testing went well. N3 was here, proven technically capable and ready to be put to work for developers. The team moved forward, and the Neo N3 MainNet launched at 9.00 a.m. (UTC) on August 2nd.

Alongside the launch came the beginning of early bird migration, allowing Neo Legacy users to become Neo N3 MainNet users for the first time. The process was initially facilitated by NEXT and O3 Labs’ NeoLine and O3 wallets respectively, each recently updated for N3. COZ soon followed with its own built-in migration tool within Neon Wallet.

NEO tokens migrated to Neo N3 would be quickly put to task voting for one of the initial council members, made up of community and NF/NGD-operated nodes. With so few votes active within the first few weeks of migration, voters received accelerated GAS rewards for playing their part in N3’s decentralization.

With the end of August began the start of mass migration from Neo Legacy to Neo N3. Over the coming months, we expect to see new users and dApps arriving on the network, ready to be the first pioneers in the next era of Neo.

Adoption of the network is now on the minds of many. All those involved in the Neo ecosystem are eager to see the first rounds of dApps on the network, many playing their own part in the transition. Though the onboarding process for any new technology is often slow initially, the first contracts have already made their way onto the N3 MainNet.

GhostMarket, an NFT minting and trading platform, claimed the prestigious title of first Neo N3 dApp. Since it was deployed on August 24th, over 400 NFTs have been minted via GhostMarket on Neo N3, 75 of which were successfully sold to patrons.

As the number of migrated assets continues to increase, more and more Neo users join the new network. With the ecosystem prepared to support a thriving dApp ecosystem, Neo now opens the doors to other first-comers. The Early Adoption grant initiative has been launched to this end, curating the best new projects while seeking to further bolster the Neo infrastructure.

On the user-facing side, a range of promotions are planned to celebrate the launch of the Neo N3 MainNet, including NFT giveaways, TestNet activities, content programs, and more. Keep an eye out on Neo’s official channels for more information.

Tooling

Below, you’ll find the latest updates and state of tooling across all the languages with support for Neo developers on the new network.

 

N3 BY LANGUAGE

C#

C# is the language used by the core Neo protocol and tooling. Neo’s core developers, together with support from Neo Global Development and other contributors, oversee protocol-level changes and maintain the official node clients, plugin modules, and C# devpack.

As the reference implementation of Neo N3, the C# codebase is usually the first place to receive the new pieces of functionality before they begin to find their way into alternative tools and languages.

PROTOCOL DEVELOPMENT

As the final release date neared, the core development team focused more heavily on code optimization over introducing functionality. Inefficiencies in binary serialization, JSON deserialization, and an out-of-memory error in JSON serialization were all uncovered and rectified in August.

By mid July, the core development team had released N3 RC4, which included logic fixes for the network fee, verification fee, and gas limit calculations. Alongside other optimizations, this new version also improved the client’s compatibility with OSX and introduced the latest features, such as the getnetwork and getrandom syscalls.

The milestone N3 release was achieved on August 1st and deployed to MainNet on the 2nd. Minor updates on the 3rd and 6th followed in quick succession as core developers worked to fix an issue with VerifyStateIndependent and remove the recently added Refuel command on account of potential DoS vectors, for which it could behave as an amplifier.

Assorted other improvements have been completed in the remainder of August, intended for inclusion in the v3.0.3 planned for release in September. Examples include a fix for CheckWitness for custom contract groups, a new witness scope, and a fix for a bug in Storage.Put that caused a variation in node state.

NEOFS PORT

Work on the C# port of NeoFS has continued. The collaborative effort between developers from NGD and Neo SPCC has yielded the release of the NeoFS.API v3.0.0, and in July testing began on the Inner Ring nodes used to govern the storage network.

Through August, the team progressed on the NeoFS client and began running tests for the storage and CLI components.

NGD ENTERPRISE

As in previous months, the Microsoft alumni of the NGD Enterprise office have continued their work to make Neo the most developer-friendly blockchain platform. Ever since it was unveiled, the Neo Blockchain Toolkit has become a must-have tool in any developer’s arsenal.

Similar to Ethereum’s Truffle suite, the Neo Blockchain Toolkit provides a suitable local environment for spinning up private networks; creating, compiling, and deploying smart contracts; and performing invocations or automated testing.

While key components such as Neo Express can be used as standalone tools, the Toolkit truly shines when used together with the included DevTracker & Debugger within VS Code. With the GUI, developers can access all the same functionality in a more convenient form, while also taking advantage of the additional block/transaction exploration and debugging tools.

In August, N3 release versions of all the included components were published, and various updates have followed since then. The team also shipped a preview of the Smart Contract Debugger for Visual Studio, following requests from the Neo community. Other components are planned to follow in the near future.

Alongside language-agnostic development infrastructure, NGD Enterprise also frequently contributes to the ecosystem through new tutorials, example C# smart contracts, core development, and strategic outreach at the enterprise and government levels.

Golang

Support for Go developers is spearheaded by Neo St Petersburg Competence Center, or Neo SPCC for short. The major contributions to the Neo ecosystem from the team are NeoFS and NeoGo.

NeoFS is a decentralized distributed object storage system designed for sleek integration with both traditional applications and smart contracts. Through the use of Neo’s native oracle system, contracts can fetch data stored off-chain on NeoFS to enable dApps to operate on large quantities of data in a cost-effective manner.

NeoGo is a full-featured alternate implementation of Neo, written in Go. Functionality is provided by a single binary, which can be used to run a powerful and high performance node capable of consensus, create/compile/deploy/invoke Go smart contracts, run the NeoVM, or access wallet functionality. NeoGo’s functionality for developers remains in constant lockstep with the core, and is quick to adapt to changes with reliable, organized, and well-documented code.

NEOFS

Through July, the team worked to enhance the NeoFS specification and launch its TestNet iteration, which aligned with N3 RC4. New versions of the HTTP and S3 gateways were released, upgrading them with various bug fixes and other improvements. Examples include support for HEAD requests in the HTTP gateway.

The team also released new utilities in this time: neofs-adm, used to simplify side chain deployment, and neofs-aio, an all-in-one docker image for running a full NeoFS network.

Neo SPCC went on to achieve N3 MainNet compatibility for NeoFS in August with the v0.23.1 node version. New features included a new API search prefix implementation and a proof of concept for enhancements to notary event listening.

Particular attention was also placed on the S3 gateway, resulting in performance improvements and other changes intended to enhance compatibility with AWS.

NEOGO

Under the hood, NeoFS makes heavy use of NeoGo. It’s no surprise then that Neo SPCC spent considerable effort improving the node with impressive optimizations. In July, most changes maintained a focus on core compatibility—the v0.96.0 releases were quickly put to test on the RC4 network as Neo SPCC’s council node.

The RC4 versions boasted a number of substantial improvements over the previous iterations: up to 5-10 times improvement in JSON and binary serialization or deserialization, and up to 5-6 times faster block processing from a TestNet dump. Various inconsistencies between the Go and C# implementations were corrected, and the team measured an estimated 10% TPS improvement.

The v0.97 releases, with MainNet compatibility, would follow closely afterwards in August. Alongside security research and a number of fixes, Neo SPCC also completed work on a P2P state exchange implementation that it had finished drafting in the previous month.

Final node optimizations also made their way into these MainNet-ready releases. In benchmark tests, NeoGo reached an impressive new high of 8,800 TPS measured in a networked test, while also reducing memory consumption when compared to the last round of benchmarking.

At this time, NeoGo remains the only alternative Neo node implementation capable of participating in consensus. This makes it a vital tool, both for helping ensure correctness across the core protocol and other infrastructure, and for improving the robustness of the N3 network itself.

Indeed, at the time of the report’s writing, the Neo SPCC council node has claimed the top spot as the most highly voted node on the network. This means NeoGo has already joined the ranks of the consensus nodes on the N3 MainNet, a milestone accomplishment in itself and a great step forward in decentralization.

Java

AxLabs is the driving force behind support for Java on Neo. The Switzerland-based team maintains neow3j, a development toolkit built to streamline the production of tools and dApps on the Java platform (including Android and Kotlin).

Functionality is primarily split between an SDK and devpack, used for building applications that integrate with the N3 network and development of smart contracts written in Java.

NEOW3J

The team produced two milestone releases, v3.12.0 and 3.13.0, in July and August respectively. The former made the library compatible with the Neo N3 MainNet for the first time, while the latter tidied up key functionality, such as the APIs for transaction building and for retrieving values from contract storage in their appropriate types.

The newest versions also include a number of changes that improve neow3j’s integration with Neo Blockchain Toolkit components, including support for Neo Express-specific RPC calls. The team also added a new interface for use with NFT smart contracts.

Whether you want to write your smart contracts in Java, add wallet functionality to a JVM-based game, or parse network data retrieved over RPC, neow3j has the tools you need. AxLabs now sets its sights on future enhancements that will further boost the toolkit’s developer friendliness and accessibility.

Python

Python support arrived on the original Neo blockchain thanks to the efforts of the COZ development community, and that legacy was continued with the shift to N3. Over the previous two months, its contributors have produced N3-compatible versions of its Python smart contract compiler and SDK, named Boa and Mamba respectively.

BOA

COZ levelled up its Python contract compiler with support for various new builtins. Examples include the count method for lists, tuples, and strings, the is keyword, and reversed.

In July, the team added support for user module imports, making it possible for developers to compile contracts which import code from other modules. This solves the inability to compile multi-file contracts while also providing an avenue for vetted contract libraries, similar to OpenZeppelin on Ethereum.

By early August, MainNet-compatibility was completed, adding the missing interops from prior releases as well as the latest ones used for random numbers and network magic checks. The v0.9.0 release also packaged a new OracleRequestCode enum, intended to improve the developer experience when using the N3 oracle system.

https://github.com/CityOfZion/neo3-boa

MAMBA

As with Boa, Mamba received various updates through the months to maintain compatibility with N3 protocol development. Two N3-ready releases were published in August, v0.9.0 and v0.9.1, which adjusted for RC4 and the MainNet v3.0.2 core node builds.

Some new features were introduced in August, such as support for the new network and random number syscalls. However, these were mostly limited to changes made at the N3 protocol level, rather than direct functionality expansions to the SDK itself.

That doesn’t mean Mamba isn’t ready for integration with Python applications however—it can already be used as a simple node with fast blockchain synchronization, and following a fix added at the end of August, correctness has been audited up to MainNet height 127,057.

Likewise, wallet functionality also remains available in Mamba, giving developers a way to create/import wallets or sign transactions in their applications.

JavaScript

JavaScript and TypeScript developers in the Neo ecosystem are sure to encounter two primary champions, COZ and NEO Tracker. As the programming language of the world wide web, it is exceptionally important to have first-class resources available for developers which can be used for all manner of web apps, websites, and other applications thanks to runtimes such as Node.

COZ and NEO Tracker are amongst the oldest development communities in the ecosystem, and each provides its own SDKs for JavaScript applications. COZ skews more heavily towards app integration with its neon-js and WalletConnect SDKs, while NEO Tracker aims to provide a full-stack framework for developers, including a full JS node implementation and smart contract compiler.

NEON-JS

Most changes to neon-js over the last two months have revolved around N3 compatibility, meaning changes required due to alterations in the core Neo protocol. Additions such as the nonce field in block headers, updated magic numbers, and others all fall under this umbrella.

Other merged pull requests involved bug fixes and other necessary improvements, such as the addition of signers to validation flow and fixes for NEP-17 transaction validation. Various other improvements to the TransactionBuilder and signing procedures were also committed. Changes include new convenience methods for adding signers and witnesses to transactions, the removal of script hash sorting on signer lists, and an altered signing function designed to accommodate Ledger devices.

The team completed an upgrade of the original NEP-9 URI package, remaining focused on the original use case of token transfers but also adding support for voting URIs. This feature built on what was originally an Ethereum proposal to add prefixes that specify URI intent. Methods for URI creation were added alongside the changes to enable applications to take advantage of the functionality.

https://github.com/CityOfZion/neon-js/tree/next

WALLETCONNECT

COZ also strove to pioneer the adoption of WalletConnect in the Neo N3 ecosystem. As an open-source and network-agnostic protocol, WalletConnect has quickly become popular across numerous blockchain networks.

The protocol enables communication between wallets and dApps, giving users the ability to authenticate various interactions. This is usually achieved with easy-to-use QR codes, which allow easy signing without a user revealing their private key to the application.

The SDK is designed for integration in JS applications, with examples for both React and non-React apps. Since a compatible wallet is also necessary for applications to test WalletConnect integrations, COZ also produced Aero, a lightweight web wallet which acts as a testing ground for the protocol.

The team released an integration guide for dApps with WalletConnect and Aero on Dojo, its Neo developer hub.

NEO•ONE

July saw the release of NEO•ONE v3.6.1-rc4 by the NEO Tracker team, rendering its node implementation capable of syncing the RC4 TestNet. As with other tools in the ecosystem, most changes were related to core protocol advancements—new syscalls, the nonce field in block headers, a config for the initial N3 GAS distribution, and a helper for the new POW opcode in the compiler.

After completing RC4 support, the team moved on to MainNet compatibility. While implementing the latest changes, such as the removal of the Refuel method, the developers also found time to clean up various other areas of the codebase. Notable fixes include improved blockchain logging and P2P message parsing, the addition of MethodTokens to the compiler, and removal of various unused types and unnecessary methods.

Towards the end of August, other new features were also added for inclusion as part of the first N3 MainNet release version. Various new sources of information were added to blockchain storage, dead code was removed, and helpful comments and new error messages were implemented to better document complicated code and explain transaction verification failures respectively.

NEO Tracker continues to iterate on its node and client packages in NEO•ONE with bug fixes, and is currently pursuing updates to its eponymous blockchain explorer in order to prime it for N3.
