Proof of Build Hackathon Brings Web3 Identity Into Focus

A Global Call to Builders

The Proof of Build event is about to make waves in the blockchain community. Scheduled for the final days of September 2025, this 10-day global hackathon invites developers, designers, and product visionaries to roll up their sleeves and create real-world applications on the Moca Network’s Open Identity Stack.

While the hackathon runs online, it all culminates with a high-profile Demo Day in Singapore on September 29 during Token2049, one of the largest web3 gatherings in the world. Top teams will showcase their products in front of investors, founders, and media — a huge opportunity for builders to gain exposure on a truly global stage.

Identity Unlocked: What Makes This Different

The theme of Proof of Build is Identity Unlocked. Participants won’t just be brainstorming ideas; they’ll be delivering working products built around verifiable credentials (VCs) and the Moca Chain identity infrastructure.

The schedule is fast-paced yet structured:

• Onboarding & Workshops: Keynotes and technical deep-dives to set the stage.

• Hacking Phase: An 8-day sprint supported by mentors and regular check-ins.

• Pitch Prep: One day to refine demos and presentations.

• Demo Day: A live showcase in Singapore during Token2049.

This format ensures teams not only experiment but also produce tools and services that can solve pressing identity challenges.

Why Web3 Identity Matters Now

The spotlight on digital identity couldn’t come at a better time. Traditional login methods like Single Sign-On (SSO) dominate the web but raise red flags around centralization, privacy, and data control. In contrast, decentralized identity promises to put ownership back in users’ hands.

Moca Network’s Proof of Build is designed to show that onchain identity isn’t just a concept. It’s a practical solution ready for builders to adopt and users to benefit from. By tying this hackathon to Token2049, Moca ensures the conversation extends from development teams to the broader web3 ecosystem.

Moca Network and Its Mission

Behind the hackathon is Moca Network, the identity division of Animoca Brands. This team is building the core infrastructure needed for digital identity in the open internet.

Key initiatives include:

• AIR Kit: A developer toolkit for integrating verifiable credentials, smart accounts, and permission systems.

• Partnerships: Support for more than 570 companies, with tools reaching over 700 million users.

• Real-world adoption: Services like SK Planet’s OK Cashbag (28M verified users) and One Football (200M+ users) are already leveraging Moca tech.

By giving users control over their identity across multiple platforms, Moca is tackling one of web3’s most fundamental challenges: trust without centralization.

Moca Chain and the Power of MOCA Coin

The technical backbone of this mission is Moca Chain, a Layer 1 blockchain designed specifically for digital identity and user data. Unlike centralized systems, Moca Chain lets users and digital agents control their own information.

Highlights include:

• EVM compatibility and modular design for seamless integration.

• Zero-knowledge proofs and decentralized storage for privacy.

• Cross-chain interoperability to connect identity across ecosystems.

• MOCA Coin as the native token for gas, staking, storage, and identity services.

As Yat Siu, co-founder of Animoca Brands, put it: centralized SSO systems are points of failure and often exploit user data. Moca Chain is built to flip that model on its head, putting ownership where it belongs — with the user.

AIR Kit and MocaPortfolio: Building Blocks for Adoption

A major enabler of this vision is AIR Kit, Moca’s SDK for handling verified data and access control. It gives developers a plug-and-play way to integrate identity systems without reinventing the wheel.

But Moca isn’t stopping there. The recent launch of MocaPortfolio introduces a new system for token allocations. Instead of one-off airdrops, users can stake MOCA Coins or Mocaverse NFTs to gain Staking Power, which can then be burned to register for ongoing token allocation events.

The first allocation features the Magic Eden (ME) token, with more to come. Mocaverse NFT holders even enjoy rate boosts when staking. This approach encourages deeper engagement with the projects users support while tying into Moca’s broader tokenomics model.

Looking Ahead: Proof of Build’s Role in Web3

The Proof of Build hackathon is more than just a coding sprint — it’s a signal of intent. By challenging builders to use its Open Identity Stack, Moca Network is making a clear statement: onchain identity is ready for prime time.

The Demo Day in Singapore will reveal how teams have tackled these challenges and provide a glimpse into the future of identity in web3. With Moca Chain, AIR Kit, and initiatives like MocaPortfolio already in motion, the network is laying a foundation that could transform how we think about data, trust, and digital ownership.
