So, what is Avail?

Avail is the comprehensive solution to problems faced in modern blockchain development.

Monolithic blockchains can’t keep up.

The technology relies on technical solutions built on decades of progress. But they need upgrades.
Customization, scalability, and debugging smart contracts leads to a host of problems.
It’s prohibitively expensive and slow to build modern applications directly on monolithic chains. There has to be a better way.

The modular evolution is here.

Decoupling the layers of the blockchain lets you optimize for your development.
Now you can scale and adapt your blockchain cheaply and efficiently.
But -- you need a foundation layer of data and consensus designed to support the whole stack, no matter what it is.

It starts with Avail.

Avail provides a fast and secure data and consensus layer that gives you all you need to launch a sustainable blockchain.
Optimized for building next-generation trust-minimized applications, sovereign rollups, and zero-knowledge or fraud-proof based blockchain applications with greater efficiency and ease.

What will you build on Avail?

Avail brings the modular foundation, so you can bring the innovation.
With Avail, your chain can become sovereign. This means freedom to build your chain the way you want.
Since Avail naturally supports any execution environment, you now have the power to create next-gen blockchain solutions like never before possible. Avail’s got you covered.

Build better blockchains, more easily than ever before.

Building blockchains doesn’t have to be complicated. Develop intuitively with a base layer built for the future.

Easy to use

No need to bootstrap your own validator set. Chains running on top inherit Avail's base layer shared security.

Scalable

Avail scales naturally, allowing developers to focus on their goals instead of infrastructure.

Trust-minimized

KZG commitments, erasure coding, and data availability sampling use cutting-edge math to ensure data is correct and protected.

Secure

Avail allows light clients to easily verify data availability through sampling over a peer-to-peer network, and inherit full node-level security and validation directly from the DA layer.

Flexible

Avail supports any blockchain execution environment, enabling devs to innovate like never before possible.

Efficient

Spin up blockchains the way you want in minutes. Avail’s robust DA API lets sovereign rollups iterate fast without compromise.

Future-ready

Blockchain technology is always advancing - build on a base layer that lets you adapt to any modular stack.

What you can build with Avail

Avail is the comprehensive solution to problems faced in modern blockchain development.

Validiums

L2 rollups that post transaction data to Avail are called Validiums.
They save up to 90% of gas fees when compared to rollups that post data directly to Ethereum.
