The rapid evolution of Web3 has shifted the focus from hype-driven tokens to real infrastructure projects that improve scalability, decentralization, security, and data availability.
As blockchains expand into financial applications, social networks, gaming ecosystems, and AI-driven systems, the demand for more advanced infrastructure grows. Five projects stand out for their transformative impact on Web3 in 2025: Ethereum, Arbitrum, EigenLayer, zkSync, and IPFS.
These initiatives address long-standing bottlenecks, high fees, slow throughput, fragile interoperability, and centralized storage. Their innovations allow developers to build fast, secure, censorship-resistant applications that can onboard millions of users. Collectively, they represent the backbone of next-generation Web3.
1. Ethereum: The Execution Layer of Web3
Ethereum continues to serve as the foundation of decentralized applications. As the first smart-contract platform to gain global adoption, it now powers thousands of dApps across DeFi, NFTs, social platforms, and gaming.
Post-Merge improvements, especially the shift to proof-of-stake, have drastically cut energy usage and improved network efficiency.
The introduction of proto-danksharding (EIP-4844) has reduced data costs for Layer-2s and boosted throughput, laying the groundwork for full sharding. Developers also enjoy a mature toolkit, including Truffle, Hardhat, Foundry, and a vast open-source ecosystem that accelerates experimentation and deployment.
Ethereum’s EVM compatibility remains a major advantage. The EVM functions as a universal standard: dozens of chains support it, and developers can deploy smart contracts across chains with minimal changes. This interoperability ensures consistency in tooling, security audits, and user experience.
Even with competition from alternative L1s, Ethereum still secures the majority of value in Web3. Its role as the settlement layer backed by billions in staked ETH cements its dominance.
The network processes the highest-value transactions and remains the base for leading DeFi protocols like Aave, Uniswap, Maker, and Lido.
2. Arbitrum: Scaling Ethereum for Mass Adoption
Layer-2 technologies are essential to scaling Ethereum without sacrificing decentralization. Among them, Arbitrum has emerged as the leading L2 by transaction volume, developer activity, and total value locked.
Arbitrum’s core innovation lies in optimistic rollups, which batch thousands of off-chain transactions and settle them on Ethereum. This process reduces gas fees by 10×: 100× while maintaining Ethereum-level security. Over time, upgrades like Arbitrum Nitro have improved execution speed, lowered latency, and enhanced compression.
What sets Arbitrum apart is its emphasis on flexibility. Arbitrum Orbit allows teams to launch custom L3 chains with specific configurations for DeFi, gaming, or enterprise applications. This approach unlocks specialized scaling without fragmenting liquidity.
The ecosystem has become a magnet for developers, helped by grants and support programs, attracting hundreds of projects. Arbitrum now powers large SocialFi and GameFi communities, offering high throughput with EVM equivalence, meaning developers can migrate from Ethereum seamlessly.
As Web3 apps demand millions of daily transactions, Arbitrum has positioned itself as a key infrastructure layer for cost-efficient and secure scaling.
3. EigenLayer: A New Security Marketplace for Web3
Security has always been one of Web3’s most expensive bottlenecks. New chains and protocols traditionally needed their own validator networks and tokenomics to secure operations. EigenLayer disrupts this model through restaking a mechanism that lets users reuse staked ETH to secure additional networks and services.
This creates a shared security marketplace. Instead of building from scratch, new protocols can rely on the massive economic weight of Ethereum’s stakers.
These external modules, called Actively Validated Services (AVS), include decentralized sequencers, oracles, bridges, data availability layers, and other middleware.
The benefits are substantial:
Lower bootstrapping costs for new projects
Higher yields for stakers through stacked rewards
Greater security via Ethereum’s validator set
Faster innovation due to modularity
By early 2025, EigenLayer had accumulated more than $12 billion in restaked ETH, making it one of the fastest-growing projects in Web3 infrastructure.
The long-term vision is to transform Ethereum’s validator network into a global, programmable security hub. If successful, EigenLayer could redefine how decentralized networks secure themselves and interact with one another.
4. zkSync: Zero-Knowledge Rollups for High-Performance Web3
As Web3 applications become more complex, especially in payments, gaming, and privacy-sensitive finance, developers need faster settlement, lower fees, and stronger cryptographic guarantees.
zkSync delivers this through zero-knowledge rollups, which compress thousands of transactions and generate zk-proofs verified directly on Ethereum.
The benefits of ZK technology are profound:
Speed: Sub-second confirmation times
Lower Costs: Dramatically cheaper than L1
Privacy: data can be validated without being revealed
Security: proofs ensure correctness by default
zkSync Era is notable for its zkEVM compatibility, enabling developers to port Solidity contracts without rewriting code.
The system also supports native account abstraction, allowing user-friendly features like gasless transactions, biometric wallet recovery, and flexible multisig authentication key components for mainstream onboarding.
The introduction of hyperchains gives projects the ability to deploy custom ZK-powered chains tailored to AI applications, high-frequency trading, gaming, and enterprise workloads. With the increased focus on ZK technologies across Web3, zkSync sits at the forefront of scalability and privacy breakthroughs.
5. IPFS: The Decentralized Data Layer of Web3
While blockchains secure transactions, Web3 still requires decentralized systems to store data, assets, metadata, and application front-ends. This is where IPFS (InterPlanetary File System) plays a foundational role.
Instead of relying on centralized servers or cloud platforms, IPFS uses content-addressed storage, where files are referenced by their unique cryptographic hash. This enables:
Permanent, tamper-resistant data storage
Censorship resistance through distributed nodes
Global content delivery without central points of failure
Interoperability with chains via pinned data
IPFS is widely used for NFT metadata, decentralized websites, and distributed archives. When paired with storage incentives through networks like Filecoin or Arweave, IPFS becomes the backbone of permanent and censorship-resistant Web3 storage.
Platforms like OpenSea, Farcaster, Lens Protocol, and numerous DAOs rely on IPFS to ensure that assets and front-ends remain accessible even if central servers fail. In a Web3 world that prioritizes transparency and permanence, IPFS is irreplaceable.
How These Projects Reshape the Web3 Landscape
Together, these five projects tackle the blockchain trilemma by specializing in different infrastructure layers:
Ethereum: Computation & settlement
Arbitrum: Scalability & affordability
EigenLayer: Security & trust minimization
zkSync: Privacy-preserving high performance
IPFS: Decentralized storage
This layered model mirrors the design of the traditional internet, with different tools working together rather than one chain doing everything.
Driving Mass Adoption
Several trends amplify the importance of these projects:
Rising demand for enterprise solutions
Increasing complexity of decentralized applications
Accelerating AI-Web3 convergence
Global movement toward self-custody and censorship resistance
The synergy between L1s, L2s, shared-security layers, and decentralized storage is unlocking trillion-dollar opportunities across finance, gaming, identity, and decentralized social networks.
Ongoing Challenges
Despite progress, Web3 infrastructure faces hurdles:
Quantum computing threats will require post-quantum cryptography.
Regulatory uncertainty could shape L2 operations or restaking rules.
Interoperability remains fragmented across chains.
Data availability is an ongoing challenge for large-scale dApps.
Yet the open-source culture of Web3 continues to drive rapid iteration. New appchains, modular blockchains, and data networks continue to emerge, expanding the possibilities for developers and users alike.
The Infrastructure Powerhouses Shaping the Future of Web3
In 2025, Web3 is undergoing a structural transformation. Rather than competing to be “the one chain to rule them all,” leading projects now cooperate through layered architectures.
Ethereum provides the secure execution foundation; Arbitrum and zkSync scale its throughput; EigenLayer distributes its economic security; and IPFS stores its data.
These five projects collectively enable a more scalable, secure, resilient, and user-friendly Web3. As adoption grows, this infrastructure-first approach will define which networks and applications succeed in the next decade.
