The development process of Unique Network in Polkadot
Unique Network sees Polkadot (the relay chain that enables parachain interoperability) as a very promising technology with which to build a large number of use cases and the future of the multi-chain world. So we built our product on Polkadot and Kusama.
Why do we trust Polkadot so much? What really attracted us was the mechanics of mass adoption and seamless interaction. As we know, Polkadot will make a significant contribution to blockchain projects by reducing the reliance on C++ to promote the adoption of blockchain projects in the way we know. We want to be part of the development of the community that created it and drive it forward.
Unique Network's commitment to Polkadot was recognized at Hackusama 2020, where we won the titles of "Build a Blockchain Champion" and "Community Choice" champion during the Kusama or Polkadot ecosystem's first hackathon (https://devpost.com /software/unique-network). Since we were awarded the official title of Polkadot Ambassador in 2019 and appointed as a key member of the Kusama NFT strategy team, our close relationship with the Polkadot team has continued to be strengthened (https://kusama.polkaassembly.io/post/303).
The same partnership applies to many of our team members, who have all received individual titles and recognition expressing our commitment to growing the Polkadot ecosystem. Unique Network CEO Alexander Mitrovich has been a Polkadot Brand Ambassador since 2019, and our Head of Metaverse Growth, Irina Karagyaur, is Polkadot's Chief Brand Ambassador for Western Europe. Collectively, they have played a vital role in facilitating Unique Network building and extending the capabilities of Polkadot, and we are proud to say that key players in the industry have taken note of us.

Polkadot Substrate C++ API
Status: Delivered
Polkadot's integrated C++ API, built on Substrate, allows reading blockchain information and state, and helps you sign and publish transactions in C++. This integration also enables users to subscribe to Substrate node WebSocket endpoints and receive data updates. Why is this good for the larger decentralized blockchain ecosystem? Because while a high-quality, well-documented API would help the community integrate with the product in general, a C++ API would be more beneficial to the Financial sector and the gaming industry.

Polkadot Substrate .NET API
Status: Delivered
Polkadot's integrated .NET API based on Substrate allows reading chain information and state, block details, and signing and publishing transactions in C# or other .NET languages. It also allows you to subscribe to Substrate node WebSocket endpoints and receive data updates.

SR25519 Library in Pure C and C#:
Status: Delivered
Previously, only one Sr25519 signature algorithm (Curve255-dalek in Rust) was in use. Having only one implementation of Rust presents two major portability problems. First, if a Rust cross-compiler is not available (like many embedded CPUs), it becomes impossible to link or call Rust libraries. Second, when a Rust compiler or cross-compiler is available, calls to Rust libraries are platform-dependent. In many cases (e.g., with .NET), finding the right compiler doesn't solve the problem, requiring additional code tweaks. SR25519 will allow multilingual developers to natively integrate with Substrate without a Rust dependency.
Regarding the integration with Substrate, SR25519 is one of the signature algorithms used by Substrate. The Alexander testnet version is based on Schnorrkel 0.1.1 and Kusama's SR25519, and the other versions are based on Schnorrkel v.0.8.5's SR25519, both of which are implemented in this authorized application.

PostgreSQL Indexer and Consensus Ensurer
Status: Delivered
PostgreSQL Indexer and Consensus Ensure is an indexer analysis that provides metadata and generates a database schema. This analysis scans blocks, extracts data from transactions, and saves it to a database table. Consensus ensures that dApp nodes communicate with the rest of the network; this function creates parallel computations in the blockchain. Our indexer will help create blockchain applications with high performance requirements for the larger ecosystem.
To extend to Substrate and Polkadot, Indexer interacts with Substrate/Polkadot via RPC interface, CE acts as a transparent layer to the client API (so dApps don't need to change), but the set of nodes to interact with will be controlled by CE rather than application maintainers to manage.

NFT Tracking Module
Status: Delivered
Finally, our NFT Tracking Module, is the fifth feature funded by Polkadot Experience Web3. This tracking module, now known as the NFT Palette, is at the heart of NFT functionality. Like the ERC-721 standard in the Ethereum ecosystem, this module provides the basis for creating NFTs, minting a given set of NFTs, and managing their ownership.

【about Us】
Unique Network is the infrastructure of a new generation of NFT and the first NFT chain of Kusama and Polkadot. Unique Network is committed to building a set of infrastructure to allow Dapps creators and developers to easily develop highly interoperable and Scalable NFT applications. The Unique Network team won the 2020 hackathon by building the first NFT — Substrapunks — on Polkadot, and also created the Substrate Pallet for NFTs. Unique Network has rich open experience in the Web3 field. It is the winner of 5 Web3 Grants, the winning team of Kusama Hackathon 2 times, an important member of the Kusama NFT strategy team, and the digital art project Chiba Gallery (Chiba Gallery) established by Kusama. Gallery) technical supporter. Unique Network will be officially launched in summer 2021.
