Neo Global Monthly Report

March 2021

Neo Global Monthly Report


March was an eventful month for Neo, with the reveal of the N3 brand, the launch of a new website, and the release of Neo N3 RC1 TestNet.

N3 is the version brand for Neo 3.0. It allows Neo Global Development to market its major releases to developers, without interrupting the regular user’s relationship with Neo’s core identity. NGD has also started referring to 2.x (the current Neo blockchain) as Neo Legacy to clearly communicate to users that it is being superseded and will not receive further updates in the future.

Following the N3 reveal, NGD released the Neo N3 RC1 TestNet – the first official N3 TestNet. This first release candidate version includes the integration of NeoFS into the oracle modules for the first time, alongside state root services and other new features. Neo’s global community also kept in lockstep with core protocol development, with RC1 compatibility immediately announced for almost all major projects, including the Neo Blockchain Toolkit, NeoGo, the Neo Python Suite, Neow3j, and more.

To reflect the new version brand and celebrate the TestNet release, NGD also launched a new website with updated information on Neo and N3. Visitors can take a tour of all the features found in N3, and learn more about ecosystem support opportunities, Neo’s mission, it’s global communities, and more. Further updates will be made in the near future to provide information on governance participation and token migration.

Moving forward, a checklist has been opened for Neo N3 release candidate two, as Neo continues along its path to the Neo N3 MainNet. A hackathon event will soon be launched to allow developers to compete for prizes and mentorship as they familiarise themselves with Neo’s new complete blockchain development platform.



N3 Progress

March saw the release of Neo N3 RC1 and its TestNet. The new version included most of the new functionality for N3, including the name service and support for NeoFS. The update also fixed bugs with the state service and moved consensus-related settings such as MaxTransactionsPerBlock and MaxBlockSize to the DBFT Plugin. Aside from assorted other optimizations, the RC1 release also added two new opcodes to the Neo contract system, POW and SQRT.

The most notable improvements in this version can be found below:

State Root Updating

Building on from the Preview releases, the core development team has been adding new features to the state root service. P2P functionality has been added, including the ExtensiblePayload to carry signatures. Several bugs have been fixed, including faulty logic where the state root witness could be null, a network magic number check before enabling state root console commands, a hash calculation logic fix, and others.

Accomplishing NeoFS API & Integrating NeoFS into Oracle Module

The team has successfully completed neofs-api-csharp and integrated it into the N3 oracle module, allowing C# nodes to easily interact with NeoFS. The master nodes used in the NeoFS RC1 test network are operated by Neo SPCC using NeoGo.

Adding POW and SQRT Opcode

The additions of the POW and SQRT opcodes are used to calculate the power and square root of a value respectively. Useful for many contracts, such as automated market makers, the new opcodes are intended to simplify the development of contracts that depend on these functions. Necessary logic changes to implement them across the Neo core, virtual machine, and .NET devpack have all been completed.

Other miscellaneous improvements

  • Removal of singletons from neo-core
  • Moving some settings from Policy Contract to DBFT Plugin
  • Allow plugins work with multiple NeoSystems
  • Native contract update history implemented
  • Adjustments to some system call fees in order to standardize the fee format
  • CpuFee and StorageFee differentiated in order to assist fee calculations

At this time, the team is preparing a task collection checklist for N3 RC2. The checklist will be frozen in mid April with the intention to release by the end of the month. Subsequently, the RC2 TestNet will be set up at the beginning of May. This is hoped to be the last RC version before the N3 MainNet release, which is planned for release around June.





Project Milestones


Flamingo Finance by NGD

Following the approval of community members, the Flamingo team implemented the redesigned asset flow as proposed in FIP #2. Migration of affected assets opened on the website after the update, allowing existing users to migrate their WBTC, WETH, and USDT-based assets to their new variants. New users could use the platform directly.

O3 Swap by O3 Labs
