SubQuery Partnership With Polkadot Name System (PNS)

Published on:

SubQuery partnership with Polkadot Name System (PNS), a decentralized domain name system for Polkadot. The team at PNS use SubQuery to rapidly query on-chain data to present their users with their digital identity information.

PNS allows you to use a ‘.dot’ domain name to show your smart contract, domain name, wallet, NFT, & other resources. From these start building a digital identity dedicated to “you”. Where previously you could only point to a string of characters and digits on the chain for items that belong to you, PNS has packaged this into your own Web3 name card (Web3Profile) which you fully possess and manage. However behind the simplicity and accessibility of your Web3Profile, is data that must be aggregate and queried to quickly and accurately display your information, this is where PNS called upon SubQuery.

To present the Web3Profile to the user, PNS must read on-chain data & display it to the user via clean & intuitive interface. Originally this process was slow and was greatly affected by the network status. In order to improve the user experience, PNS decided they would leverage SubQuery’s data indexing service.

Data indexing framework of SubQuery

The data indexing framework of SubQuery can be used to read & save the on-chain data to the database after deployment. This means the subsequent query doesn’t need to go to the chain, rather, it can just query the database directly. Moreover, SubQuery also provides a GraphQL interface, which can facilitate the front-end to flexibly query and call data. This improves the users’ experience and reduces development effort for PNS.

Vision of decentralization

One significant reason why PNS chose to rely on SubQuery is vision of decentralization that is shared between both teams. With the upcoming SubQuery Network, PNS can completely decentralise their data indexers, and benefit from improved uptime, reliability, and performance that this brings. PNS will be one of the first teams to take advantage of the decentralised SubQuery Network when it launches.

PNS are using SubQuery Projects to manage their own project and make updates as required. They take advantage of SubQuery’s enterprise-level hosting to receive dedicated databases, automated deployments, and geographic routing to multiple clusters around the world for performance and uptime.

About PNS — Polkadot Name System

PNS a decentralized domain name system for Polkadot. You can use a .dot domain name to support smart contracts, domain names, wallets, NFTs, etc., thereby building a domain-specific chain that has its own parameterization and features. With the application of PNS, you can create your very own digital identity for Web 3.0 with a domain name that you have full permission to manage and use.

About SubQuery

SubQuery a blockchain developer toolkit enabling others to build Web3 applications of the future. A SubQuery project is a complete API to organise and query data from layer-1 chains. Servicing Polkadot, Substrate and Avalanche projects, this data-as-a-service allows developers to focus on their core use case and front-end, without needing to waste time on building a custom backend for data processing. The SubQuery Network proposes to enable this same scalable and reliable solution, but in a completely decentralized way.
