Elastic scaling is a crucial upgrade for Polkadot, especially for parachains requiring higher throughput. It allows parachains to produce multiple blocks for each Relay Chain block, processed in parallel, enhancing transaction speed. The new model introduces Agile Coretime, permitting flexible core assignment, even for short durations. This facilitates cost-effective scaling as projects can purchase coretime as needed, reducing entry barriers for developers. Compared to other scaling models like roll-ups, Polkadot's approach maintains security while improving scalability. Additionally, CoreJAM and CorePlay extensions promise further enhancements, ensuring Polkadot remains at the forefront of Web3 adoption.
