# Scalability

Key features to enhance scalability are:

**Transaction Merging**: ZK Rollups aggregate hundreds of off-mainnet (Ethereum) transactions and send only one proof to the blockchain (ZK-SNARK). This significantly relieves the network load and increases throughput due to layered optimizations. Lower cumulative costs as the number of Layer 1 submissions is minimized and optimized.

**Parallel Processing**: Transactions can be processed in parallel to one another, increasing speed and efficiency. That alone is a scalable infrastructure that can handle a significantly larger volume of transactions than Layer 1 only.

**Near DA** along with **Nuffle Fast Finality Layer** provide unmatched scalability, security, and speed for Haust Network. This solution aims to solve the challenges of state and liquidity fragmentation while offering fast finality across chains. These technologies bring additional advantages by supporting more users and transactions without overloading the blockchain and running smoothly as we grow.
