The world of Web3 promises a decentralized future, but a significant hurdle stands in the way: scalability. Blockchains, contrary to popular belief, are poorly suited by their very design to process tons of transactions at the speed and scale required for mass adoption. Ethereum co-founder Vitalik Buterin refers to this constraint as the “Scalability Trilemma.” It underscores the need to balance decentralization, scalability, and security all at once. Avail Stack offers a hopeful reprieve by bringing them a full-stack cure. This approach addresses major pain points and furthers the full potential of blockchain technology.

Traditional blockchains face several scalability-related issues. If a network has a limited transaction capacity, it will quickly become congested under high demand, causing confirmation times to soar and transaction fees to spike. Imagine a one lane country road. As more cars are added, traffic quickly grinds to a halt. Likewise, when a blockchain network is overloaded, it takes longer to process a transaction, and it costs more to submit one. Layer 1 (on-chain) solutions, which require changing the central code of the blockchain, provide greater relief. These solutions often have trade-offs, such as sacrificing decentralization or security.

Avail Stack takes a different approach. Rather than attempting to address the scalability challenge inside just one blockchain, it embraces a modular architecture. This involves breaking out various functions to standalone layers, enabling increased adaptability and extensibility. This modularity is a foundational concept in how Avail is solving some of Web3’s biggest challenges.

Understanding Avail's Modular Approach

The technology Avail Stack is built on uses a modular architecture, spinning up specialized layers that naturally fit together to improve scalability and interoperability. This approach gives developers the freedom to pick and choose the tools that work best for them. It delivers adaptability while maximizing efficiency across a wide range of blockchain use cases.

Data Availability (DA) Layer

At the core of Avail Stack is its Data Availability (DA) layer, Avail DA. That last layer especially seeks to make sure that each transaction’s data is both easily accessible and independently verifiable. In short, it serves as a public ledger where all transaction details are written. Unlike Avail DA, which does a great job of looking at data availability, this unique approach lets it achieve much higher efficiency and scalability than traditional blockchains, which compound data storage with transaction execution. Like rollups, appchains can scale by executing transactions off-chain. They trust Avail to make sure that their data is there, secure, and as affordable as possible.

Avail uses Nominated Proof of Stake (NPoS), a decentralized blockchain consensus mechanism, to ensure its DA layer is secure. With NPoS, transactions are always validated in the fastest manner possible while remaining secure. Avail uses proof aggregation, combining many execution proofs into a single zero-knowledge proof. This enables decentralized and verifiable cross-chain state updates. This allows diverse blockchain networks to seamlessly converse and transact with each other. Light Clients are another key piece, allowing for permissionless mobile-first decentralization and end-user verification. Now users can check the integrity of the data that’s displayed on the Avail DA layer right from their mobile devices. They no longer have to trust and use a centralized and vulnerable intermediary.

Avail Nexus: The Interoperability Hub

Avail Nexus provides a permissionless coordination hub that enables effortless interaction between blockchain ecosystems. It enables users to instantly and easily move assets and information from one chain to another. This makes the user experience immensely better and fosters even more interoperability across the Web3 ecosystem.

Avail Nexus bridges the gaps of divided liquidity and unique ecosystems. It offers an all-inclusive, integrated ecosystem to improve interoperability and cross-chain conversations and complete transactions smoothly. Such training helps developers create applications that take full advantage of an ecosystem of interoperable blockchains. This way, they’re able to build more flexible and robust solutions. By making it easier to interact across chains, Avail Nexus fosters a more integrated and cooperative Web3 ecosystem.

Real-World Applications and Impact

The Avail Stack is more than just an academic concept. It powers real-world applications today and holds the promise to reimagine the Web3 landscape.

SocialFi Revolution

Sophon, a SocialFi application developed on the Avail Stack, provides an interesting case study. So far, Sophon has run more than 80 million transactions. It houses 23 live applications, demonstrating just how scalable and efficient the Avail Stack can be. SocialFi platforms like Sophon combine social networking with decentralized finance (DeFi), allowing users to earn rewards for creating and sharing content. The Avail Stack gives the developers the infrastructure they need to support all those high-volume applications, fostering this new generation of social experiences.

DeFi Empowerment

As mentioned previously, the Avail Stack’s unified liquidity and cross-chain connectivity are integral advantages for DeFi applications. From popular decentralized exchanges like Uniswap to decentralized lending protocols like Aave, you can find them on just about every chain. No redeployment required to put them to use! This allows users to easily trade and lend assets between multiple blockchain networks, thereby boosting liquidity and efficiency. By removing the silos between DeFi ecosystems, Avail Stack helps build a more interconnected and accessible financial system.

Layer 2 and Layer 3 Scaling

Avail Stack’s modular infrastructure and horizontal scalability vision make it a compelling basis for L2 and L3 scaling solutions. Sophon by Futureverse is an awe-inspiring zk-validium network. It leverages Avail’s data availability layer to provide extreme throughput and maintain a focus on low transaction costs. Layer 2 and 3 scaling solutions lighten the burden of transaction processing beyond the base layer blockchain—efforts that can save substantial fees. This not only increases scalability, but lessens congestion. 700vl, CC BY 2.0 Avail Stack provides a robust and trusted DA stack. This technical improvement has a positive effect making scaling solutions faster and more secure.

Web3 Applications

The Avail Stack includes cutting-edge technologies such as Turbo DA, Enigma upgrades and Light Clients. These technological advancements and innovations supercharge other diverse Web3 applications, making this a seriously powerful platform. These technologies allow developers to create applications that have a great need for scalability, decentralization and security. Turbo DA, for instance, takes this impact even further, boosting data availability by improving the efficiency of data distribution all across the network. Enigma upgrades bring new privacy-preserving encrypted data analysis solutions. These solutions give institutions the ability to develop private use applications while remaining in enterprise-wide compliance with regulations.

Institutional Adoption

Government agencies and other institutional use cases will find the Enigma DA Upgrade especially compelling. It offers a privacy-preserving encrypted DA solution, enabling institutions to develop their own private applications and services to meet the demands of regulatory bodies. This is especially important for sectors such as finance and healthcare, where data privacy is of the utmost importance. By providing surety and compliance within the Avail Stack platform, institutional players can be better enabled to adopt this exciting new foundational technology.
