🔦✨ Spotlight on: Elastic Scaling

Polkadot is redefining blockchain scalability with Elastic Scaling, Agile Coretime, and Async Backing, enabling parachains to produce multiple blocks per Relay Chain block.

Together, these form the backbone of Polkadot 2.0—advancing scalable, efficient Web3 apps promised to the builders.

What are Cores? 💡

Core = resources used to validate a block from a parachain on the Relay Chain.

Example: if the Relay Chain validates 25 blocks from parachains simultaneously, it’s using 25 cores.

Agile Coretime enabled parachains to lease extra cores short-term to handle spikes in demand—saving costs and boosting performance.

Here’s the big deal. With Elastic Scaling, parachains can also bundle and scale cores on demand.
Why Elastic Scaling Really Matters ⚡️

→ On-Demand Resources: chains can add cores (more computer power) when needed, releasing them afterward.

→ Cost-Efficient Growth: Match blockspace with actual demand—no waste, no unnecessary spending.

→ Adaptive Performance: Instantly scale to handle surges, ensuring smooth user experiences.

And this isn't theory. During the Spammening event, @kusamanetwork achieved 143k+ TPS across 23/100 cores via Agile Coretime + Elastic Scaling, demonstrating the capabilities of the Polkadot SDK in a real-world environment.
And more cores can be added as demand grows 🤯

Wen Elastic Scaling? 👀

Elastic Scaling is live on Kusama and set to launch on Polkadot in 2025. See more from @paritytech's dev roadmap: https://t.co/3bN1UEaQKB

With these upgrades, Polkadot becomes a true multi-core shared world computer, offering the best scalability and efficiency in the market for Web3 builders without compromising its resilience.
