OVERVIEW
So, what is Avail?
Avail is the comprehensive solution to problems faced in modern blockchain
development.
01
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.


02
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.


03
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.


04
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.



WHY AVAIL
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.

USE CASES
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.

Sovereign Rollups
 * Avail lets you build a blockchain in minutes - not months.
 * Update the logic on your chain without redeploying a smart contract
 * Interoperate with any other rollups on Avail.

App-specific Chains
 * Your chain, your rules.
 * Create application-specific chains with Avail for ultimate control of your
   state, and execution environment.

VISION
We envision a world where blockchain technology seamlessly integrates into
people's lives
transforming how institutions, communities, and individuals coordinate
unlocking endless possibilities for a more transparent, secure, and equitable
world.
