Asynchronous Backing increased how much work the network can process. Elastic Scaling determines how that capacity is allocated. A single parachain can now use multiple cores at once, scaling throughput when demand rises.

The relay chain assigns multiple cores to the same parachain. Each core processes a different block in parallel, while ordering is enforced so state remains consistent.

Those extra cores can be acquired on demand via Agile Coretime, and released as demand subsides. The result is higher throughput, better congestion handling, and stronger economics; well suited for real-time workloads in DeFi, games, social applications, and IoT systems.
