The blockchain scalability race has dominated headlines in 2025, with Layer 2 (L2) solutions emerging as one of the most promising frontiers. As these networks mature, they promise faster transactions and drastically reduced fees—fueling a new wave of Web3 applications. With this growth comes an inevitable surge in data generation, placing immense pressure on storage infrastructure. In this context, decentralized storage—a sector often overlooked by mainstream attention—could soon become a critical pillar of the Web3 ecosystem.
One project capturing early momentum is EthStorage, winner of the EDCON Super Demo 2023. By building directly atop Ethereum’s data availability layer, EthStorage offers a compelling vision for scalable, programmable, and truly decentralized storage. This article explores the evolution of network storage, Ethereum's modular future, and how projects like EthStorage are redefining what’s possible in Web3 storage.
The Evolution of Network Storage
Data storage has undergone a radical transformation since the dawn of computing. We can break its development into four distinct phases, each reflecting broader technological shifts.
1. Centralized Storage: Centralized Infrastructure, Centralized Control
In the early days, data was stored on physical media like punch cards. The invention of the hard disk by IBM in 1956 marked the beginning of modern digital storage. Today’s centralized systems—using HDDs, SSDs, or cloud drives—still follow this foundational model: data resides in a single location, managed and controlled by a central authority.
While efficient for performance and maintenance, this architecture creates single points of failure and gives users little control over their own data.
2. Cloud Storage: Distributed Infrastructure, Centralized Management
The launch of Amazon Web Services (AWS) in 2006 revolutionized storage with cloud-based models like S3. Data is now distributed across multiple servers globally, offering redundancy, scalability, and resilience against hardware failures.
However, despite the distributed backend, control remains firmly in the hands of providers like AWS, Google Cloud, or Alibaba. Users rent space but don’t own or fully govern their data—a limitation increasingly at odds with Web3 principles.
3. Traditional Blockchain Storage: Fully Replicated, Decentralized Management
Bitcoin and Ethereum introduced a paradigm shift: storing data across a decentralized network where every node holds a full copy. This ensures censorship resistance and immutability but at a steep cost.
Storing even small files on-chain is prohibitively expensive due to limited block space and high gas fees. For example, uploading NFT metadata directly to Ethereum could cost hundreds of dollars—making it impractical for widespread use.

4. Web3 Decentralized Storage: Scalable, Multi-Node, and User-Owned
To overcome on-chain limitations, new Web3-native solutions have emerged—IPFS, Filecoin, Arweave, Storj, Swarm, and now EthStorage—each aiming to deliver affordable, scalable, and decentralized storage without sacrificing ownership.
These systems split data into fragments, distribute them across nodes, and use cryptographic proofs to verify integrity—all while keeping control in users’ hands.
Ethereum’s Modular Future and the World Computer Vision
Ethereum’s Modular Architecture
Since 2021, Ethereum has pursued a modular design centered around Rollups—a strategy often referred to as the "Endgame" by Vitalik Buterin. Instead of handling all functions on one chain (a monolithic blockchain), Ethereum breaks down operations into specialized layers:
- Execution Layer: Processes transactions and runs smart contracts.
- Settlement Layer: Finalizes rollup results and resolves disputes.
- Consensus Layer: Ensures agreement among validators.
- Data Availability (DA) Layer: Guarantees that transaction data is published and accessible.
This modular approach allows Ethereum to focus on security and consensus while delegating execution and storage to L2s. The result? A more scalable, flexible foundation capable of supporting global-scale applications.
The World Computer: Balancing Consensus, Computation, and Storage
Ethereum’s ultimate goal is to become a “world computer”—a decentralized supercomputer powering all digital interactions. But achieving this requires solving a trilemma: balancing consensus, computation, and storage.
Each component imposes trade-offs:
- Strong consensus demands replication, limiting scalability.
- High computation needs repeated verification, straining network resources.
- Large-scale storage requires frequent proof checks, impacting performance.
A breakthrough concept proposed in “Towards World Supercomputer” suggests decomposing the world computer into three separate peer-to-peer networks:
- Consensus Ledger (e.g., Ethereum)
- Computation Network (e.g., zkOracle)
- Storage Network (e.g., EthStorage)
These components communicate via trustless bridges—like zero-knowledge proofs—enabling modular expansion while preserving decentralization and security.

Introducing EthStorage: Ethereum’s First Programmable Storage L2
What Is EthStorage?
EthStorage is the first Layer 2 solution built on Ethereum’s data availability layer to offer programmable dynamic storage at 1/100th to 1/1000th the cost of on-chain alternatives. Capable of scaling to hundreds of terabytes—or even petabytes—it aims to solve Ethereum’s growing data burden.
Backed twice by grants from the Ethereum Foundation and recognized as EDCON 2023 Super Demo champion, EthStorage represents a major leap forward in Web3 infrastructure.
Key Technical Advantages
Seamless Ethereum Integration
EthStorage extends Geth—the most widely used Ethereum client—so nodes can simultaneously serve as both Ethereum validators and EthStorage data providers. This dual role strengthens network security and reduces operational overhead.
Users interact using existing wallets, enabling frictionless integration with dApps ranging from NFT platforms to decentralized social networks.
Unlike Arweave—which requires multiple cross-chain transactions—EthStorage executes everything within a single Ethereum transaction, ensuring atomicity and ease of use.
L2 Architecture Built for Storage
While typical Rollups scale computation by moving state execution off-chain, EthStorage scales storage by moving data off-chain while anchoring proofs on Ethereum.
- On-chain: A smart contract verifies storage commitments.
- Off-chain: Data is stored across a distributed network; updates trigger new cryptographic proofs.
This makes EthStorage not just a storage layer, but a modular component compatible with any EVM chain that supports data availability—even other L2s like Optimism.
Dynamic CRUD Operations
Most decentralized storage systems (like Filecoin or Arweave) support only immutable uploads—data cannot be updated or deleted. EthStorage changes that with full CRUD support (Create, Read, Update, Delete), thanks to its key-value storage model.
This opens doors for dynamic applications: editable NFT metadata, live-updating dApp frontends, version-controlled code repositories—all while remaining fully decentralized.
ERC-4804: The Web3 URL Standard
EthStorage founder Qi Zhou introduced ERC-4804, the first official Web3 URL standard approved through the EIP process. Also known as web3://, it enables direct access to resources hosted on Ethereum smart contracts—HTML pages, images, PDFs—without relying on centralized servers.
Think of it as decentralized HTTP. Just as http:// points to server-hosted content, web3:// resolves to EVM-stored assets. This creates a fully on-chain browsing experience—immune to takedowns or censorship.
Use Cases and Roadmap
Real-World Applications
With EthStorage, developers can rebuild dApps with end-to-end decentralization:
- Dynamic NFTs: Update artwork or metadata in real time.
- DeWeb Sites: Host censorship-resistant websites directly on-chain.
- Decentralized GitHub (De-Git): Store open-source code immutably.
- On-chain Music NFTs: Store audio files with programmable royalties.
- No-host Wallets: Store recovery kits securely off-server.
Currently in testnet phase, EthStorage allows developers to experiment using test tokens (W3Q). No tokenomics have been announced yet.
Future Development
According to its public roadmap:
- 2023–2024: Testnet development aligned with Ethereum’s Cancun upgrade.
- 2024 Onward: Mainnet launch featuring full Danksharding integration, CL+EL client support, and native Web3 browser access.
Competing Decentralized Storage Projects
While EthStorage brings innovation in programmability and integration, other projects lead in different niches:
- Filecoin: Built on IPFS with economic incentives; supports FVM for smart contracts; ideal for large-scale static storage.
- Arweave: “Pay once, store forever” model; excellent for archival; limited interoperability.
- BNB Greenfield: Tightly integrated with BSC; uses S3-like buckets; strong within Binance ecosystem.
Each serves distinct needs—but only EthStorage offers dynamic updates within the Ethereum ecosystem.
