Avail aims to facilitate a complete change in how we approach the design of blockchain systems. Avail enables modular chain design where various execution environments can use Avail for data ordering and availability. Avail is agnostic to the execution layer, which can be the standalone chains or off-chain scaling solutions that use Avail. The applications hosted on these execution layers enjoy the full security of Avail.
