Understanding Data Availability

At its core, data availability ensures that all transaction data remains accessible, even if it isn’t stored directly on the blockchain. This is essential because without guaranteed access to the full transaction history, users and validators can’t verify the integrity of the chain.

The Data Availability Layer (DAL) solves this by storing and verifying transaction data off-chain. This allows Layer 2 solutions like Haust to process transactions faster while keeping the blockchain unclogged and secure.

In simple terms:

• The blockchain holds a record of what happened.
• The DA layer ensures that anyone can retrieve the full data behind those records at any time.

This guarantees trust and verifiability without sacrificing performance.

A Warehouse Analogy

Imagine a blockchain as a warehouse. Traditionally, every “box” (transaction) had to be stored inside the warehouse itself, taking up space and slowing down operations.

With DA, the warehouse no longer holds every box. Instead, it keeps a detailed logbook that records exactly where each box is stored in a nearby, secure storage facility.

• The warehouse stays organized and efficient.
• Anyone can still check the contents of a box at any time.
• The system can handle more boxes without running out of room.

This is what DA does for blockchains: it keeps them fast, efficient, and uncluttered while preserving verifiability.

The Rise of Data Availability Solutions

As the Web3 ecosystem matured, several DA solutions were developed to handle the growing volume of off-chain data. Some of the most prominent include:

• Celestia — A modular blockchain that separates execution and data availability, optimizing block space for L2s.
• Ethereum Proto-Danksharding (EIP-4844) — Improves how Layer 2s post transaction data back to Ethereum, reducing costs.
• NEAR DA — Leverages NEAR Protocol’s high-throughput sharded architecture to deliver low-cost, scalable data availability.

Each solution has its strengths, but for Haust Network, NEAR DA stood out as the most efficient, scalable, and cost-effective option.

Why Haust Chose NEAR DA

NEAR DA offers a compelling combination of scalability, performance, and affordability that makes it ideal for Haust’s zk-rollup ecosystem.

Key Advantages

1️⃣ Cost-Effective Block Space
NEAR DA delivers extremely low storage costs — around $0.0016 per block — significantly cheaper than Celestia ($0.046) and Ethereum ($7.73). This allows Haust to keep transaction fees low, even during peak demand.

2️⃣ High Throughput
With 16 MB/s throughput, NEAR DA outpaces Celestia (6.67 MB/s) and Ethereum (1.33 MB/s). This means it can handle more transactions in parallel, preventing bottlenecks.

3️⃣ Gas Efficiency
NEAR DA facilitates roughly 2.8 billion gas per second, vastly outperforming competitors. This ensures that even under heavy network load, data remains accessible and the system stays responsive.

4️⃣ Sharding for Scalability
Sharding allows multiple transactions to be processed simultaneously across different shards. This parallel processing capability means that as usage grows, Haust can scale without sacrificing performance.

5️⃣ Security Layers
NEAR DA adds extra cryptographic checks to guarantee data integrity and prevent censorship or data unavailability attacks.

How Haust Puts NEAR DA to Work

At Haust, NEAR DA is more than just a supporting technology — it’s a core part of our infrastructure.

By leveraging NEAR DA, Haust can:

• Offload data from the main chain while keeping it verifiable.
• Reduce congestion and keep fees predictable.
• Enable faster finality for zk-rollup transactions.

To make this even more powerful, Haust pairs NEAR DA with the Nuffle Fast Finality Layer (NFFL). This combination speeds up transaction confirmation times and further reduces costs — creating a user experience that feels seamless.

Integrating Multiple Solutions

Haust’s approach is not to rely on a single technology but to build a composable, modular infrastructure.

While NEAR DA handles data availability, Haust integrates with AggLayer to tackle liquidity and interoperability challenges.

• NEAR DA ensures that data stays accessible and secure.
• AggLayer optimizes cross-chain liquidity flow, reducing slippage and improving execution for DeFi trades.

The result is a network that not only scales but also delivers a superior user experience across different chains and ecosystems.

Why This Matters

For users, developers, and liquidity providers, this architecture has significant benefits:

• Lower fees — thanks to efficient data storage and reduced gas consumption.
• Faster transactions — finality is reached quicker, making DeFi feel more like Web2 speed.
• Greater security — extra DA verification ensures no transaction data is lost or censored.
• Better UX — dApps built on Haust can scale without bottlenecks, even during network surges.

This is the infrastructure Web3 needs to transition from experimental to mainstream adoption.

The Bigger Vision

The launch of NEAR DA integration is just one step in Haust Network’s journey. As DeFi grows more complex, the importance of robust, modular solutions will only increase. Haust is positioning itself as an ecosystem where data availability, liquidity, security, and scalability all work together seamlessly.

Our mission is simple: build a blockchain network that feels fast, safe, and cost-efficient — even as millions of users join.

By combining technologies like NEAR DA, NFFL, and AggLayer, Haust is paving the way for a more reliable and user-friendly DeFi experience.
