What is Polkadot coretime?

Coretime is access to Polkadot computation and blockspace. Projects can use bulk coretime for predictable access or on-demand coretime when they need it.

What does an available core mean?

An available core is offered for the next coretime period and has not yet been purchased or renewed. It is different from an idle core in the current period.

Can several parachains share one core?

Yes. Coretime can be partitioned or interlaced so that more than one assignment uses different parts of the same core.
