How Avail DA is a Game-Changer for Ternoa 2.0 and the Future of PayFi Rollups
Blockchain scalability has always been a challenge, especially for high-throughput applications like payments. While Layer 2 solutions (L2s) have made great strides, they often face trade-offs between decentralization, security, and cost efficiency. This is where modular data availability (DA) solutions like Avail come in, providing an innovative approach to solving these bottlenecks.
With the launch of Ternoa 2.0 zkEVM+, built with Polygon CDK and Avail DA, we are seeing a powerful example of how modular DA enables next-generation blockchain applications—especially in PayFi (Payments + DeFi). As a validator on both Avail Mainnet and Polygon PoS, I want to break down why this integration is such a game-changer for the industry.
The Scalability Bottleneck: Why Data Availability Matters
Most rollups today still rely on Ethereum or other L1 chains for data availability, leading to high costs and congestion. For applications handling millions of transactions—like a crypto-powered payments network—this model simply doesn’t scale efficiently.
Avail solves this problem by offering a dedicated, decentralized DA layer that allows rollups to store and verify transaction data without depending on costly and congested L1 chains. This reduces fees, improves throughput, and enhances security.
For projects like Ternoa 2.0, which is focused on retail crypto payments and financial services, using Avail DA means:
✔️ Cheaper transactions for users
✔️ High throughput for scaling PayFi applications
✔️ Increased security with trust-minimized proofs
Ternoa 2.0: The First Real-World Test for Avail DA in PayFi
Ternoa has spent four years developing TEE (Trusted Execution Environment) security to enhance blockchain privacy and integrity. Now, with their zkEVM+ rollup, they are leveraging Avail DA to enable large-scale payments adoption.
How Ternoa is Using Avail DA
1. Retail Crypto Payments at Scale
Ternoa is launching a decentralized finance protocol that will be integrated into 40,000 retail points of sale across the GCC region.
This means over a million retail users will interact with blockchain payments without experiencing slow transactions or high fees—something only possible due to Avail DA’s scalability.
2. Secure & Cost-Effective Smart Contracts
By offloading data availability to Avail instead of Ethereum, Ternoa 2.0 can dramatically reduce costs for developers building smart contracts.
Instead of storing transaction data on Ethereum at high costs, Ternoa can post it to Avail’s DA layer, ensuring decentralization while maintaining affordability.
3. Enhanced Interoperability via AggLayer
Since Ternoa 2.0 will be connected to AggLayer, it needs a modular DA that can support cross-chain execution and shared liquidity.
Avail’s DA enables multiple chains to access transaction data, ensuring smooth interaction between different L2s and sovereign chains.
Why This Matters for the Future of Blockchain Payments
Ternoa 2.0 is just the beginning. Modular DA solutions like Avail will become the standard for scalable, low-cost rollups. Here’s what this means for the broader ecosystem:
✅ Cheaper Crypto Payments: Projects can launch high-speed, low-cost PayFi solutions without worrying about Ethereum gas fees.
✅ Mass Adoption Possibilities: Businesses can onboard users at scale without requiring deep blockchain knowledge.
✅ Interoperability & Liquidity Sharing: More chains using Avail DA means seamless cross-chain interactions via AggLayer.
Final Thoughts: A Validator’s Perspective on Avail DA
As a validator on Avail Mainnet since its launch, I’ve seen firsthand how decentralized DA is changing blockchain infrastructure. The ability for rollups like Ternoa 2.0 to separate execution from data availability is a fundamental shift—one that allows developers to build more efficient, scalable, and decentralized applications.
The combination of Polygon CDK, Avail DA, and AggLayer is setting the stage for a truly modular blockchain future, and Ternoa 2.0 is proving that it works in real-world payment applications.
As more L2s recognize the need for cost-efficient, scalable data availability, Avail DA will likely become a key pillar of the modular blockchain stack—powering everything from payments to DeFi to gaming.
The future of blockchain is modular, and Avail DA is leading the way.
