If we were to visualize @Polkadot Core, it might look like this: the core is a pink energy ball, continuously supplied by the computation and execution power of all validators in Polkadot!
If you pay with DOT, you can press the top Coretime button, and then the pink energy can be unleashed, allowing the surrounding magnet pieces to connect to your rollup, and in the future, they can also connect to the services you have on JAM.
Depending on your needs, you can pay different fees, for example:
When the demand is low, you only need to press once.
If the demand is high, you can choose to long press continuously.
If one core is not enough, you can press multiple core buttons simultaneously to release more pink energy.
