Neo Global Monthly Report

Highlights

August was filled with milestones for the Neo ecosystem, led by the release of Neo3 Preview3 on August 7th. As the latest release on the road to Neo3 MainNet, Preview3 focused on protocol improvements and bug fixes, intended to help community teams currently updating existing development tools and infrastructure by providing a more stable platform to work on.

Updates included a new block synchronisation mechanism, governance features, and smart contract system improvements.

Just one week later, the Neo2 MainNet was upgraded to run version 2.11.0 of Neo’s core client. The new version incorporated state root as a method for checking data consistency between different nodes, and allowed for its distribution via the P2P messages emitted during consensus.

This paved the way for the release of Poly Network, a new protocol alliance formed to facilitate cross-chain transactions between all participating blockchains without issuing a new token and with minimal overhead needed for integration.

The network currently supports cross-chain transactions between Neo, Ethereum, Ontology, and Cosmos, with the intention to add Bitcoin support in the near future. Switcheo, one of Poly Network’s founding members, was the first to make use of the protocol with the launch of TradeHub – it’s new stand alone order matching engine. Switcheo TradeHub is currently processing millions of dollars in cross chain transactions, and will also be the foundation for Switcheo’s upcoming derivatives exchange.

To top off a big month, Neo announced Flamingo Finance – a new Neo-based full-stack decentralized finance protocol. Under incubation by Neo Global Development, Flamingo is expected to begin rolling out in September 2020, with features such as a cross-chain asset gateway, automated market making (AMM)-based swaps, synthetic stablecoins, and AMM-based perpetual trading contracts.

Flamingo Finance is intended to fill the gaps of missing DeFi pieces within the Neo ecosystem and will feature its own Neo-based project token, FLM, which will be 100% distributed through contribution-based participation from the community.

On the announcement of Flamingo, Da Hongfei said, “This is just the beginning. As a community-driven open ecosystem, Neo welcomes all public chains, developers, and investors to build the smart economy of the future with us together.”

The full August monthly report can be found below.

PROTOCOL DEVELOPMENT

PROTOCOL DEVELOPMENT

Neo3 Progress

With Neo3 Preview3 released on August 3rd, Neo took one step closer to shipping Neo3. The next step is to release Preview4, expected in October, which will likely be the release candidate version used for the official Neo3 TestNet. This version will add more features including the built-in oracle, economic model update, state root support and more. Several of these features have already been merged into the master branch, including some significant optimizations.

PROTOCOL DEVELOPMENT

Neo3 Preview 3

Unlike the previous releases, Preview3 was more stable and included the majority of protocol layer functions. In particular, two key changes were included in this release:

  1. Neo enhanced the smart contract module with a try-catch mechanism for exception handling and a contract callback feature. The Main method was also removed as a single point of entry.
  2. The foundations were laid down for the governance mechanism, responsible for managing the committee. This will be followed by the economic model in the next release, allowing community developers to prepare tools and infrastructure to enable this functionality for Neo3.

PROTOCOL DEVELOPMENT

Governance & Economic Model

One of the most significant improvements for Neo3 is the governance & economic model. The system is designed to encourage NEO holders to participate in Neo’s decentralization by actively participating in governance, achieved in part by providing stronger incentives for voters. Neo3 Preview3 included the code for the governance model (#1491), and branches for the economic model are now being merged, including the incentive for NEO holders (#1845), the incentive for committee members (#1847), and the incentive for voters (#1848). The next steps will involve collaborating with community development teams to bring the new governance features to NEO holders in a more user-friendly manner.

PROTOCOL DEVELOPMENT

State Root

Neo3

To prevent delaying the launch of the Neo3 MainNet, the decision was made to continue with state root distribution through P2P messages, however the relevant issue (#1526) will remain open for further discussion. If improved solutions are found, the approach can be changed after MainNet launch. The implementation was completed in the neox branch, however due to a logic dependency the PR (#1793) has been temporarily closed until optimizations for disk usage are applied to Neo2. The optimization logic will first be applied to Neo2.x, then included with #1793 for the master branch.

Neo2.x

All pull requests related to state root functionality have been merged into the master-2.x branch, completing the implementation. Now live on MainNet, this feature is in use by the cross-chain interoperability protocol Poly Network, which launched on August 18th, 2020 with Neo, Ontology, and Switcheo as founding members. The previously mentioned disk usage optimization is currently under development (#1878) and involves refactoring work for the Merkle Patricia Trie. An additional PR will also be submitted to enable a node to only store the current state.

PROTOCOL DEVELOPMENT

Oracles

Following many back and forth discussions regarding the asynchronous and synchronous oracle solutions (#1676) (#1738), the core developers elected to focus on the asynchronous solution. The final decision was made due to problems for oracle transactions in the mempool when using the synchronous approach. Work is now underway on an OracleService plugin for the neo-modules repository, which will be used for implementation and testing.

PROTOCOL DEVELOPMENT

Infrastructure Impact

Several other key infrastructure improvements have been completed this month, including parallelized transaction verification (#1507). This was achieved by splitting the transaction verification into two parts, one state dependent and one state independent, and running the latter in parallel using a separate Akka actor pool. The result is a potential TPS improvement of up to 3 or 4 times.

Other noteworthy changes include the addition of an exception method for CreateContract (#1787), adding the ability for committee members to send high priority transactions (#1816), and allowed smart contract verification (#1800 and #628). The priority was also raised on Ping/Pong messages to assist with node synchronization (#1812), and a restriction to the nesting depth in Neo’s try/catch logic was added to prevent nodes running out of memory (#365).

INFRASTRUCTURE & TOOLS DEVELOPMENT

INFRASTRUCTURE & TOOLS DEVELOPMENT

Overview

This month, we have adjusted the format of the Infrastructure & Tools section. The shift to project-based milestones should make it easier to follow the progression of each community product as Neo’s tooling continues to mature. Similar project types have been grouped together in the report for convenience.

Currently, most Neo development communities are primarily focused on developing Neo3 Preview3-compatible versions of their existing tools. The updates provide similar functionality to those found on Neo2, in some cases introducing new features enabled by platform improvements.

MARKETING & OPERATIONS

MARKETING & OPERATIONS

Overview

In August, Neo continued its efforts towards its strategic position as the “Digital Asset Protocol” of the smart economy.

Heterogenous blockchain network interoperability is no longer theory on paper. The launch of Poly Network equipped Neo with the capability to migrate assets from major networks such as Bitcoin, Ethereum, COSMOS SDK-based blockchains, and Ontology with low friction. The Poly Network open alliance is welcoming partners and networks to join the effort to further expand the reach.

On the adoption front, Neo announced a major initiative to support the open-source project Rosetta, started by Coinbase, which lays the foundation of seamless asset access and management into Rosetta compatible digital asset wallets. This work compliments the deepening collaboration effort with organizations such as the BSN network and IWA

In his recent article: Up the DeFi Game: Introducing Flamingo, Hongfei emphasized the importance of a robust DeFi infrastructure to the Neo ecosystem, and announced the launch of Flamingo, an interoperable full-stack DeFi protocol on Neo. Flamingo will accelerate DeFi adoption by introducing our last few missing pieces: a cross chain asset gateway, an AMM-based on-chain liquidity provision mechanism, and an algorithm based collateralized stablecoin. The Flamingo litepaper and further details will be released this week to all community members. The project is expected to roll out in phases starting in September.
