These marketplaces serve as platforms for creators to showcase and sell their digital assets, while also providing collectors with a curated selection of unique NFTs. Examples of Polkadot NFT marketplaces include Kusama NFT Gallery, RMRK, and Polkabase. These marketplaces offer a diverse range of NFTs, from digital art and collectibles to virtual real estate and gaming assets.

Its goal is to become the first and most important oracle provider for all Substrate blockchains, and eventually cover the entire Polkadot network. Cloudchain data is connected to smart contracts through Chainlink oracles, unlocking new markets and business models for enterprises. One of the applications with great potential is derivative contracts, especially those developed through BitQuery to access blockchain data. Google Cloud developers can currently develop derivatives such as futures and options contracts based on the Ethereum average Gas price for a certain period of time. Ethereum smart contracts can also use Chainlink oracles to request Gas price data from BitQuery to execute contracts. Blockchain smart contracts can implement a variety of novel decentralized applications, but they cannot connect to off-chain data (such as Tesla’s stock price or user payment data on Venmo) to trigger on-chain transactions.
The team behind the project has a proven track record in the blockchain industry and has already gained significant traction through several high-profile partnerships. We believe that as the Ethereum network continues to expand, the platform will grow in popularity and has the potential to generate attractive returns for investors. However, it is expensive to aggregate data on the chain, and in order to keep pace with market price fluctuations, most projects need to continuously update the on-chain price data. It is the DeFi price reference data released by Chainlink, which allows users to easily access all price reference data of the Chainlink oracle network in one interface. Users can find the recently released reference data on the platform and easily access the detailed infrastructure, functions, and real-time / historical data of the decentralized oracle network.
The nodes in the Chainlink decentralized oracle machine network have undergone security assessment, are resistant to witch attacks, and are completely independent. The operators of these nodes are the industry’s leading blockchain DevOps and security teams, many of which are experienced in POS node operations and manage millions of $ worth of assets in multiple blockchain networks. The Chainlink protocol provides users with a trusted market environment in which users can obtain high-quality oracle services and a customizable decentralized framework. Chainlink is quickly becoming a benchmark in Oracle-as-a-Service, and is sought after by the entire blockchain industry. The users of the Chainlink network include some DeFi projects and large enterprises (such as Synthetix and Google). The Relay Chain serves as the heart of the Polkadot network, facilitating communication and coordination between different Parachains.
Hackusama – Hack on Polkadot’s Wild Cousin
Watch the Introduction to Hackusama webinar for a complete overview and technical presentation about Kusama and Substrate. If you are interested in the development of Chainlink, welcome to come and ask me for more development information. There is a Workshop I recorded a few days ago to teach everyone how to develop a quiz application. Affected by the covid, our meetup tradition has been changed to online live broadcast, but the frequency is higher.
Complete cryptocurrency market coverage with live coin prices, charts and crypto market cap featuring coins on 926 exchanges. In Polkadot, preemptive and arbitrage robots will definitely exist, but not necessarily more (in proportion). Fortunately, there will be additional first-price auctions among traders, and the proceeds will flow to the treasury.
One of the main challenges is the need to educate and onboard new users to the platform. As Polkadot is a relatively new player in the NFT space, it is crucial to provide resources and support for creators and collectors to navigate the ecosystem effectively. Additionally, ensuring the security and integrity of NFT transactions is paramount, as any vulnerabilities or exploits could undermine trust and confidence in the ecosystem.
In the existing on-chain aggregation mode, each oracle (ie, a node) has to pay a gas fee in order to transmit off-chain data polkabase to the chain. If there are 10 nodes collecting off-chain data, 10 gas fees must be paid; and the gas fee may need to be adjusted multiple times before the final settlement. The Polkadot NFT ecosystem presents exciting opportunities for creators and collectors alike. Creators can leverage the platform’s scalability and interoperability to reach a wider audience and monetize their digital creations.
Opportunities and Challenges in the Polkadot NFT Ecosystem
- The oracle node can also obtain data from multiple data sources, which avoids single-point failure problems such as data errors that may occur in a single data source or inaccessible data sources.
- Ethereum smart contracts can also use Chainlink oracles to request Gas price data from BitQuery to execute contracts.
- The operators of these nodes are the industry’s leading blockchain DevOps and security teams, many of which are experienced in POS node operations and manage millions of $ worth of assets in multiple blockchain networks.
- While Ethereum-based NFTs cannot be directly transferred to Polkadot, there are bridge solutions being developed to enable interoperability between the two ecosystems.
- Therefore, each node in the network obtains data from the same trusted data aggregator.
- We believe that as the Ethereum network continues to expand, the platform will grow in popularity and has the potential to generate attractive returns for investors.
DeFi is a new blockchain segmentation field that uses smart contracts to reconstruct traditional financial instruments, including loans, derivatives, exchanges, and reserve assets. Under the DeFi model, the financial system is no longer monopolized by centralized private institutions. Instead, it uses automated protocols to establish a trustless mechanism in the entire process, coordinate user interaction, and decentralize the back-end architecture. Chainlink has completed the initial access on the Substrate blockchain, which marks a major milestone for Chainlink’s decentralized oracle network, achieving docking with the Substrate blockchain ecosystem and Polkadot. Developers using the Substrate framework can enjoy Parity’s latest and unique blockchain technology, including pluggable consensus and forkless upgrades. In addition, the blockchain of the Substrate framework can be easily connected to the Polkadot network to ensure security and interoperability.

After the nodes obtain the data, they aggregate into a single data off-chain and send it to the chain. This ensures that DeFi applications can continuously access high-quality market data. However, Chainlink is not only opening blockchain data to cloud services, but opening cloud services to smart contracts on the chain.
Therefore, the designers of Ethereum draw on this concept and refer to the “Turing complete smart contract” figure. The official community in Chainlink is very positive, and it is forbidden to discuss the currency price. Everyone is learning and discussing about the Tech, such as discussing the application scenarios of oracles. The Polkadot NFT ecosystem is still in its early stages, but there are already notable projects and artists making their mark.
Almost all infrastructure in the public chain field is designed and implemented around the core idea of decentralization. For oracles, decentralization means higher security, more general applicability, fewer trust requirements, and higher availability. It should be noted that there is not a thing called a oracle, which can help the blockchain to achieve data connectivity, but we call this component that can achieve data communication, named “oracle”. Substrate, used for the Chainlink integration, is the groundbreaking blockchain development framework from Parity Technologies, tech company of Polkadot, also is the one of most branding blockchain tech company. While Ethereum has dominated the NFT space, a new player has emerged to challenge its supremacy – Polkadot.
