A Year in Parachains, Part 4: Sustainability, IoT, NFTs, Gaming, & Metaverse
It’s been a little over a year since parachains first launched on Polkadot, and already the network boasts the largest ecosystem of use-case specific blockchains in the world. Since the first slot auctions took place in November 2021 and the first parachains began onboarding to the network the following month, 42 parachains have joined Polkadot, with an additional 42 parachains on Polkadot’s canary network, Kusama, for a total of 84 across the Polkadot ecosystem.
Over the past year, Polkadot’s first parachains have been busy rolling out and upgrading their technologies, demonstrating the power and flexibility that Polkadot provides with the parachain model, which gives teams a competitive advantage by enabling them to fully customize their own layer-1 blockchain in the optimal way for their use case, with industry-leading upgradeability and interoperability capabilities.
Showing the potential of Web3 to fuel innovation across a wide range of use cases, Polkadot’s ecosystem of parachains is now buzzing with activity across DeFi, smart contracts, social media, decentralized identity, IoT, gaming, the metaverse, sustainability, and more.
This series of posts provides a brief overview of Polkadot’s parachain landscape in its first year since launch, starting in Part 1 with a look at Polkadot’s DeFi (Decentralized Finance) parachains, and continuing in Part 2 with a look at Polkadot’s system parachains, smart contract, and social media parachains, and Part 3 diving into to data, identity, privacy, storage, and infrastructure parachains. In Part 4, we look at Polkadot’s sustainability, IoT, NFT, gaming, and metaverse parachains, featured in the order that they won a parachain slot auction.
Sustainability initiatives like carbon tokenization, carbon credits marketplaces, and ethical commodities are a ripe field for Web3 innovation.

Nodle is a decentralized network for IoT that incentivizes users for turning their smartphones into nodes that secure the network and provide connectivity for devices around them in a decentralized wireless network. This allows smart devices without an internet connection to communicate without the need for additional infrastructure, reducing costs and barriers to entry for connectivity.
Nodle’s ‘smart missions’ allow developers to create use cases on the Nodle parachain, leveraging the network’s connected smartphones for various functions, services and applications — essentially Web3 apps that can connect to devices in the real world. Nodle is one of the most highly-adopted IoT projects in Web3, having already connected millions of devices and processed millions of transactions across 100+ countries.
Gaming, NFTs, and the metaverse have proven to be some of the most popular blockchain use cases in recent years. In particular, the ability for users to have provable ownership over digital art and in-game assets has been a game-changer. But projects built on legacy networks have seen numerous challenges, including high gas fees, limited management and ownership options, smart contract latency, and a lack of cross-platform interoperability.
Polkadot’s parachains are building the next generation of NFT and blockchain gaming technology, with innovative new features not seen in other ecosystems and with the added benefits of Polkadot’s industry-leading interoperability, scalability, and optimization.

Beyond the parachains currently on Polkadot, an additional 43 have joined Kusama, Polkadot’s canary network. Kusama is where brilliant builders come to innovate, providing a live, value-bearing environment for teams to battle-test their technologies and mitigate risk, build a community, and develop partnerships before a production deployment to Polkadot, or to build and iterate more experimental use cases.
Current use cases on Kusama generally mirror those on Polkadot, with an added focus on DAOs (Decentralized Autonomous Organizations) and Artificial Intelligence:
Many teams maintain a parachain on both Polkadot and Kusama, using Kusama to battle-test new technologies before rolling out upgrades to their Polkadot mainnet.
Despite the difficult year for blockchain in 2022, the Polkadot community and ecosystem delivered several key innovations over the past year, and now boasts the largest ecosystem of layer-1 chains, with over 300 decentralized applications already built on top of them, as well as the largest community of full-time developers outside of Ethereum.
With a ton of new projects in the pipeline, new parachains will continue rolling out over the next year and beyond, and existing parachains will continue building on their recent successes, rolling out new technologies and onboarding a new wave of Web3 end-users.
Several key technologies are also in development for Polkadot, which will push the capabilities of parachains and dapps even further, including trustless interoperability with external networks with the rollout of XCM v3 and the Bridge Hub parachain. With everything that’s happening in the Polkadot ecosystem, 2023 is shaping up to be the biggest year yet for Web3 innovation.
