A Year in Parachains, Part 3: Data, ID, Privacy, Storage, & Infrastructure

It’s been just 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, 39 parachains have joined Polkadot, with an additional 43 parachains on Polkadot’s canary network, Kusama, for a total of 82 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. In Part 3, we dive into Polkadot’s parachains related to data, identity, privacy, storage, and infrastructure, featured in the order that they won a parachain slot auction.

Polkadot’s data, storage, privacy & infrastructure parachains

Data is the currency and foundation of today’s internet, representing a resource more valuable than gold. The shortcomings of Web2 in respecting and protecting data from misuse and theft were a significant catalyst for the Web3 vision, so it comes as no surprise that Polkadot parachains are addressing these fundamental concerns.

Polkadot’s data, storage, privacy and infrastructure parachains are helping make a better web the reality, unlocking fairer and more user-centric modes of creating, storing, processing, contextualizing, and transmitting data and transactions for end users, businesses, and organizations. These projects are enabling a web where data ownership, control, and privacy are handed back to the user, all the while improving the standards of service available and bringing several efficiencies over Web2 systems.

Polkadot’s identity parachains

Decentralized identity services are one of the core use cases of Web3. In the Web2 era, our digital identities are fragmented across every online service we use, and are controlled by the platforms we use rather than by us. This leaves our personal data vulnerable to hackers and the centralized companies that own, control, and monetize our sensitive data. An ever-growing number of companies and institutions have demonstrated their inability to keep our sensitive private data safe.

Still, most everyday internet users probably don’t think twice about what happens behind the scenes when they log into their favorite web services. In reality, the usernames and passwords we use to unlock our most sensitive data and assets are being held by each service provider we interact with, often under less-than-ideal security conditions. Fraud, identity theft, extortion—the consequences of managing authentication in this way can often be catastrophic. What’s needed are Web3 alternatives that protect our interests while providing the same user experience we're accustomed to today.

LITENTRY↗
Auction 15: Onboarded June 4th, 2022
Litentry is a cross-chain decentralized identity (DID) platform that securely aggregates user data from multiple blockchain networks and off-chain applications to create a singular DID that functions across the entire Web3 ecosystem.

SocialKYC, a service for proving control of an email address and social media accounts, DIDsign, a decentralized way to sign and timestamp any digital file, and web3name, a naming service for representing your Web3 ID, are three KILT services that users can try today.

In 2022 KILT launched several impactful partnerships, including with Germany’s ministry of energy to provide vital services demonstrating how blockchain can be used in a highly-regulated industry. Originally launched on Kusama, KILT became the first parachain to migrate from Kusama to Polkadot in October 2022.

Kusama Parachains

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.

What’s Next?

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.
