The year 2022 ended with a cascade of black swan events and market downturns, setting the stage for a transformative 2023 in the Web3 landscape. As decentralization regains its spotlight amid growing concerns over censorship and centralized failures, entrepreneurs and developers are asking: What Web3 startup directions are worth building in 2023?
This guide explores high-potential areas identified by leading Web3 accelerators and communities—focusing on innovation, real-world utility, and long-term sustainability. Whether you're a developer, founder, or investor, these insights can help you navigate the next wave of decentralized technology.
1 Decentralized Infrastructure: The Foundation of True Web3
True decentralization is no longer optional—it's essential. With recent collapses of centralized crypto institutions and increased global financial surveillance, the importance of a fully decentralized tech stack has never been clearer.
An application is only as decentralized as its most centralized layer. To build resilient dApps, every component must be decentralized:
- DNS (e.g., Handshake)
- Data storage (e.g., Filecoin, Arweave)
- Data indexing (e.g., The Graph)
- Oracles (e.g., Chainlink)
- Cross-chain bridges
- Node infrastructure
- Wallets
- CDNs and ISPs (e.g., Helium)
Despite progress, most existing solutions remain in proof-of-concept stages. Even mature projects often lack enterprise-grade performance—such as low-latency access or SQL-like query interfaces—leaving room for better alternatives.

2 Developer Experience: Bridging the Web2-to-Web3 Gap
Building on Web3 should be as easy as launching an app on AWS. Yet today, developers face steep complexity: managing keys, handling gas fees, integrating wallets, and orchestrating multi-layered protocols.
Solutions that simplify this experience will drive mass adoption:
- Web3 IDEs with one-click deployment to IPFS and ENS
- Hardhat/Foundry equivalents for non-EVM chains like Solana and Cosmos
- LLM-powered coding assistants that generate boilerplate code, suggest improvements, or explain complex smart contracts in plain English
Imagine typing “Create a token vesting contract” and having an AI generate secure, audited Solidity code instantly. This isn’t sci-fi—it’s the future of developer tooling.
3 On-Chain Gaming: Where Composability Meets Play
On-chain games store not just assets but entire game logic and state on the blockchain. Think Tic-Tac-Toe where moves, rules, and player turns are immutably recorded.
This unlocks revolutionary possibilities:
- Smart contract players competing or collaborating with humans (e.g., MEV bots in DeFi)
- Trustless alliances via smart contracts—no fear of betrayal
- User-created mods that can’t be censored by platforms
While current engines focus on adding Web3 features to Web2 games, the real opportunity lies in building tools for fully on-chain experiences. Could we one day have a decentralized D&D rulebook that anyone can fork and reuse?
The first successful Web3 game engine may come from a studio that built a hit on-chain game—just as Unreal Engine emerged from Epic Games.
4 Consumer Applications: Building the Web3 Super App
Users want seamless, all-in-one experiences. The ideal Web3 consumer app resembles WeChat: a single interface to chat, pay, play, and interact with dApps.
Key verticals include:
Web3 Social Media
A true “Web3 Twitter” must offer:
- User-owned data
- Permissionless client creation
- Customizable curation algorithms
- Resistance to censorship
But history suggests it won’t look like Twitter at launch. It might emerge from a gaming app or DeFi platform first.
Messaging Apps
A decentralized WhatsApp should be:
- End-to-end encrypted
- Built on user-controlled data (e.g., via IPFS)
- Uncensorable and portable across clients
- Natively integrated with crypto payments
Start with crypto-native users—they value privacy and decentralization most.
5 Proof of Physical Work (PoPW): Incentivizing Real-World Action
PoPW networks reward users for real-world contributions using blockchain incentives. Use cases include:
- Health data sharing: Users contribute DNA or wearable data for medical research, earning tokens.
- Environmental action: Clean waterways or recycling efforts are verified and rewarded.
- Energy sharing: Households deploy batteries into a shared grid, earning tokens during peak demand.
- AI training data: Humans label images or validate datasets for machine learning models.
The challenge? The oracle problem—how to prove off-chain work on-chain without manipulation. Projects like Helium and Hivemapper use hardware validation (e.g., GPS spoofing resistance), but universal solutions remain elusive.
Zero-knowledge proofs (ZKPs) could help verify contributions privately and securely.
6 Zero-Knowledge Proofs: Privacy, Performance, and Innovation
ZKPs are becoming foundational across Web3. They enable privacy without sacrificing verifiability.
Key Applications:
- Private DeFi: Hide transaction details (sender, amount) while keeping systemic risk metrics public.
- Privacy auctions: Prevent front-running by letting bidders submit encrypted offers.
- ZK-Rollups: Scale blockchains with low-cost validity proofs.
- ZK-Bridges: Enable trustless cross-chain messaging with minimal overhead.
Advanced ZKP development frameworks—akin to TensorFlow for AI—are critical. Tools that abstract complexity, support multiple backends (CPU/GPU), and offer debugging environments will empower builders.
Hardware acceleration for ZKPs is another frontier. Just as NVIDIA powered AI, specialized ZKP chips could become highly valuable.
7 Appchains: Sovereignty for High-Performance dApps
Appchains—blockchains tailored for specific applications—are gaining traction. dYdX’s move to a standalone chain exemplifies this trend.
Benefits include:
- Predictable gas fees
- Customizable consensus
- Full control over upgrades
- Better performance for games or DeFi
StarkEx supports high TPS for games; we expect new architectures to push beyond 100K TPS on-chain.
Security remains a concern. Shared security models—where validators stake ETH to protect appchains—could mitigate risks, similar to liquid staking protocols.
8 DeSci: Decentralizing Scientific Research
Science suffers from underfunding and data scarcity. Web3 offers solutions:
- Token-incentivized data collection (e.g., genetic datasets)
- DAOs funding high-risk experiments
- ZKPs protecting participant privacy in health studies
Imagine a decentralized 23andMe where users own their data and earn rewards for contributing to drug discovery.
9 DeFi Evolution: Stability, Privacy, and Institutional Access
Decentralized Stablecoins
After FTX’s collapse, trustless stablecoins are more relevant than ever. Unlike centralized versions, they eliminate counterparty risk.
Cash Flow Lending
DAOs and companies earning recurring revenue (e.g., protocol fees) can use it as collateral for loans—unlocking working capital without selling tokens.
Privacy-Preserving Trading
Platforms that hide user identities, asset types, and transaction amounts—while keeping risk metrics transparent—will attract sophisticated traders.
10 AI + Web3: The Next Frontier
AI and Web3 are natural allies:
- LLMs as coding partners: Generate smart contracts from natural language.
- AI-driven audits: Detect vulnerabilities faster than humans.
- On-device AI markets: Rent idle GPU power peer-to-peer instead of relying on cloud giants.
Crucially, AI thrives in Web3 environments:
- No risk of account bans
- No friction from repeated transactions
- Seamless integration with dApps
The first successful Web3 social or gaming apps may be those that embrace AI—not resist it.
11 Verticalization: Winning by Niche Focus
General-purpose tools like OpenSea or MetaMask dominate—but they can’t serve everyone well.
Opportunities exist in verticalizing:
- By region (e.g., NFT marketplaces for Southeast Asia)
- By user type (pro vs. casual traders)
- By industry (music NFTs, gaming items)
- By chain (Solana-only wallets)
- By device (mobile-first interfaces)
Identify underserved segments. Build narrowly. Win deeply.
12 DAOs as Risk-Sharing Vehicles
High-risk professionals—gamers, creators, hackers—can pool resources via DAOs:
- Share income from successful members
- Fund promising newcomers
- Provide marketing and distribution support
DAOs outperform traditional entities when:
- Members are global
- Anonymity is desired
- Membership changes frequently
13 Digital Nations: The Future of Online Communities
NFT communities can evolve into digital nations:
- Shared identity (via NFTs)
- Economic activity (DeFi, NFTs)
- Governance (on-chain voting)
- Vision for real-world impact
From online group to sovereign digital nation—the path is open.
