Neo Global Monthly Report

Highlights

As we close the book on another year, the Neo community can look back and be proud of all that has been achieved in the last 12 months. 2020 was a year like no other. The COVID-19 pandemic forced everyone to re-imagine their personal and professional lives. Many sacrifices have been made, and new habits forged.

Neo has come through it with the help of our community and we move into 2021 with strength. Three new Neo3 Preview versions shipped in 2020, with Preview4 – the most complete and performant to date – landing in December.

Neo’s global community developer groups have been hard at work, with almost all major infrastructure and tooling projects reporting levels of Preview4 compatibility.

Together we are building the foundations for the next evolution of Neo and the digital economy. It speaks volumes about the cohesion of our community that we are doing it in tandem. The work that has been completed in 2020 and in the early stages of 2021 will make it a joy for new developers to build applications on Neo deep into the future.

The full December Neo global monthly report can be found below.

PROTOCOL DEVELOPMENT

PROTOCOL DEVELOPMENT

Neo3 Progress

December brought with it the release of Neo3 Preview4, a major accomplishment by core developers and other contributors. The update introduced Neo3 in its most stable and performant form so far, and officially debuted a number of new features including the Oracle service and NEP-17 functionality. Preview4 also provided optimizations and supplements for the committee governance strategy and implemented the revitalized economic model.

Core developers are also currently working to migrate state root logic from neo-core to neo-modules. The Oracle plugin is also under development, which will support the operation of oracle nodes.

Despite the accomplishments in December, new and unfinished tasks have prompted the team to release a Preview5 version. This final Preview release will include almost all Neo3 features and logic. The Preview5 checklist can be found here; approximately half of the PRs have already been merged.

PROTOCOL DEVELOPMENT

StateRoot

Neo3

Several PRs have been created following the decision to move state root logic to a new state service plugin, located in neo-modules. #410 moves the MPT data structure to the service module, whilst #414 will enable nodes to store only the latest state locally. Core developers are also working on the underlying logic for the state service, including storage and validation, command & RPC, P2P messages, etc.

Neo2

The core development team has decided to close PR #1878, regarding MPT refactoring, in order to focus their efforts on the development of Neo3. This issue may be reopened later when more development resources are available.

PROTOCOL DEVELOPMENT

Oracle

The oracle service also saw a range of improvements throughout December, with several optimizations and fixes implemented (#326) in preparation for testing in Preview5. Examples include the replacement of HashsetCache with ConcurrentDictionary, prevention of multiple starts, and the addition of the CheckOracleAccount method.

PROTOCOL DEVELOPMENT

Infrastructure Impact

December also saw the introduction of various improvements to the smart contract system for Neo3, such as the ManagementContract (#2119), a new native contract which is responsible for managing all contracts. The Contract Create, Update, and Destroy methods have been moved to the native contract as methods, whilst ContractState and ContractIdState are added as storage entries. This contract also allows native contracts to be deployed in any block through use of the ActiveBlockIndex field.

Other improvements include persistence of the original hash for a contract after modification, simplifying contract upgrading and infrastructure maintenance (#2044). A new MinimumDeploymentFee, set to 10 GAS, was also introduced to regulate deployment and prevent spam (#2140, #2153).

Developers using Preview4 will also discover the new opcode/interop service pricing model. The new model uses coefficient values for prices alongside an adjustable base price to allow committee members to scale costs up or down as necessary (#2045).

Other improvements include the new CALLT opcode, which enables the calling of specified token logic in NeoVM (#382) using the new method tokens (#2185), and simplifications for the iterator APIs (#2190). Core developers also completed the non-fungible token native contract base class in December, which will be used in the Neo Name Service (NNS) to allow users to send and receive via aliases instead of addresses (#2177).

Finally, the team also finished upgrading each part of the codebase from .NET 3.0 to .NET 5.0, the new major release of the framework (#2083, #396, #681, #407).

Project Milestones

DEFI

Flamingo Finance by NGD

In December, the Flamingo team proposed the first Flamingo Improvement Proposal (FIP), allowing the community to decide on whether to use GAS generated by nNEO as a reward for the Perp trading competition. Though the proposal did not pass, it represented a milestone achievement for the governance transition of the Flamingo project. Another proposal will be initiated following community discussion regarding a more appropriate distribution method.
