The Basics

Avail’s ecosystem is designed to offer a superior experience for both users and developers, balancing the essentials of scalability, interoperability and security without compromise. The platform’s structure is anchored in three primary layers:
Data Availability (DA) Layer: A foundational layer focused exclusively on DA, forming the basis for abundantly scalable modular chains. The DA layer is a highly optimized, low-level layer specifically constructed for data availability(opens in a new tab). This is the deepest blockchain layer, with the minimal functionality required to build cross-ecosystem interoperability on top. Avail DA uses validity proofs to ensure that developers can verify their data’s availability without trusting Avail’s claims.
Nexus Layer: Nexus is a light but powerful proof aggregation and sequencer selection zk rollup on top of Avail DA. Avail Nexus acts as a permissionless verification hub that will unify rollups (not just those built within the Avail ecosystem), leveraging Avail DA as the root of trust.
Fusion Security Layer: Enhances the overall security of the Avail network by pooling different tokens, including established tokens and emerging tokens. Fusion will also help bring and lock more liquidity from other blockchains into the Avail ecosystem. This approach will progressively bolster Avail’s crypto-economic security and marks one of the first instances where foreign tokens like ETH and BTC are utilized to power consensus on a different blockchain.
These layers collectively aim to dissolve the market’s fragmentation, providing a unified platform for users and developers from various ecosystems.
There are currently less than 100 active validators(producing blocks and earning rewards). The network-wide APR can fluctuate but is currently around 15%. Staking Rewards accrue every ERA (1 day), and you can choose to have the rewards auto-compound, sent to your liquid account balance or to the liquid account balance of an entirely different account. Unstaking takes 28 days, during which you will NOT earn rewards.
Your tokens will stay in your custody when nominate $AVAIL with a validator. This means you can, at any point, undelegate. Slashing is active on Avail. Slashing can occur under the following conditions:
Equivocation - producing two blocks in the same slot. In GRANDPA, it is sending pre-vote or pre-commit messages for two chains that conflict with each other in the same round. This will slash the validator and nominators.
If more than 10% of the validators go offline simultaneously and are chilled in an epoch, all of those validators (not nominators) will be slashed.
This means it's important to nominate validators you can trust!
