Blockchains scaled—and then splintered. Liquidity scattered across L2s, bridges kept breaking, and “data availability” turned into the new bottleneck. Avail wants to solve all three at once. Founded to deliver verifiable, scalable data availability, the project now positions itself as a full-stack unification layer: a DA base, Nexus for proof-based interoperability, and Fusion for shared security that can restake ETH, BTC, and rollup tokens. The thesis is simple but ambitious: developers should build once and scale everywhere; users shouldn’t have to think about chains at all.
Interoperability is the other pillar. Rather than another bridge, Nexus promises “one SDK, nine chains, no network switching,” aiming to route flows across multichain stablecoin and DeFi liquidity while minimizing replay and quorum risks with TEE and ZK verification. On the user side, Avail’s light client targets <1 MB/s bandwidth and runs on phones and browsers via data-availability sampling and validity proofs—pushing “a full node in your pocket” toward emerging markets.
We also explore the speed-vs-decentralization trade-offs behind TurboDA’s 250 ms pre-confirmations and the team’s “infinity blocks” research goal of 10 GB blocks in ~600 ms; the validator-set growth path from 105 validators and a Nakamoto coefficient of 34; and what Avail is learning from flagship deployments like Lens Chain (650k profiles) and Sophon. With 50+ integrations in the queue, Arjun outlines how Avail triages partners for technical fit, ecosystem value, and compliance—plus how community growth (600k+ members in year one) is anchored in builder activity rather than vanity metrics.
If Avail is right, the next phase of crypto won’t be “L2 vs. L2” but app-centric rollups speaking a common, proof-based language—privacy-aware when needed, credibly neutral by design, and finally usable at internet scale. Read on for the full conversation.
