Unique Network blockchain in the Polkadot ecosystem can be seen as a foundation for standards and good practices serving for any software that uses or relates to NFT. The core components of Unique blockchain are NFT Pallet and Ink! Smart Contracts. Like ERC-721 Ethereum standard for smart contracts, NFT Pallet provides the basement for creating collections of NFTs, minting tokens, managing their ownership, and much more. The smart contracts module is included to handle any application logic that is unknown at the time of chain design. The Unique Network aims to provide the feature rich and flexible configuration experience to its users. This includes multiple authorization levels, economic models that enable freemium application marketing, miscellaneous administration options, advanced spam protection. The goal is to cover the broad spectrum of NFT applications’ development needs and provide maximum flexibility at low to affordable cost. The Unique network is based on Polkadot Substrate, and works just like any blockchain based on it.

The story started with Unique Network’s inception and recognition at Hackusama, the first-ever hackathon for the Kusama/Polkadot ecosystem that ran in 2020, with the development of the Substrapunks game that was welcomed by the crypto community and received a high level of popularity. The 10,000 NFT characters were all claimed in a few days, and shortly after peer-to-peer trading began for valuable assets such as ETH and KSM. Following on that, the team decided to build an on-chain marketplace PoC to facilitate safe trading, explore the possible dApp architectures, experiment with miscellaneous types of loads, and discover and overcome possible problems in a developer-friendly environment. The first version of Unique marketplace was launched in November 2020. This marketplace is one of the first (if not the first) decentralized apps that is also acting as a bridge between multiple networks in the Kusama ecosystem. Unique Network, the first NFT chain built for Polkadot and Kusama, is made to solve some limitations with running NFTs on Ethereum. As a fully scalable blockchain for composable NFTs for advanced economies, the technology and infrastructure aim to provide a sustainable future free of limitations, delays, and the hindrances that plague NFTs today. Quartz, the canary network of Unique Network, won the 14th parachain slot auction and will soon be a Kusama Parachain, soon giving us a glance at the advanced features of the network.
