Coretime, without the jargon

Six things worth knowing

Short explanations for reading the explorer correctly.

01

What is a core?

A core is a unit of Polkadot computation that can validate parachain blocks.

02

What is coretime?

Coretime is the right to use that computation for a defined period.

03

Bulk vs on-demand

Bulk is predictable access for a period. On-demand is purchased only when needed.

04

What is a ParaID?

A network-specific numeric identifier assigned to a parachain or parathread.

05

What is renewal?

Eligible projects can preserve access into the next period under capped pricing rules.

06

Can a core be shared?

Yes. Interlacing lets several assignments use different slices of one core.
