On Polkadot, Rollups officially welcome the era of 'Elastic Scalability'!
In the traditional model, each Rollup can use at most 1 core, which means:
Fixed 6 seconds delay
1.7 MB data availability bandwidth per second
Thousand-level TPS limit
Now, Rollups can dynamically use up to 12 cores as needed, with each core corresponding to:
1.7MB/s data bandwidth
6 seconds deterministic delay
Multi-chain level concurrent execution capability
This means a Rollup can achieve:
20.4 MB/s data bandwidth (12 cores)
Maintain 6 seconds low latency
Elastic throughput capacity reaching tens of thousands of TPS
Rollups are no longer limited to a single execution thread, but can truly 'elastic scale' and dynamically allocate on-chain resources according to the load.
This provides the best balance of performance and cost for high-frequency applications such as games, DeFi, and social networks.
More importantly—none of this requires leaving the Polkadot main chain ecosystem, introducing additional security assumptions, or relying on a centralized data availability layer.
This is not just a simple 'scalability enhancement', but a revolution in symmetric multi-processing (SMP) for blockchains through Polkadot's native multi-core architecture.
