For non-system chains, the current route is Agile Coretime: teams buy execution time in bulk or on demand using DOT. The earlier model of competitive lease auctions, often funded through crowdloans, is historical—not the current onboarding path.
What is a Polkadot parachain?
A parachain is an independent, chain-like system connected to Polkadot’s relay chain. Its state transitions are validated by relay-chain validators, while the relay chain coordinates validators, data availability, core scheduling, shared security and cross-chain communication. Most application-specific behavior belongs to the connected chains rather than the relay chain. The Polkadot Wiki’s parachain guide describes this architecture.

Connected chains share the relay chain’s security assumptions. For example, the Wiki says a relay-chain revert would also affect connected parachains, preserving system-wide consistency. This shared infrastructure is the point of the design; it does not make every connected chain’s application, governance or business model identical.

The Wiki says a chain team decides whether a native token makes economic sense for its project. DOT matters to non-system chains because they use it to purchase coretime, but a chain’s token policy is a separate choice.

What is a core, and what does coretime buy?
A core is a virtual execution resource on Polkadot. Coretime is the right to use that resource for a period or when needed. In practical terms, it buys a chain access to relay-chain computation and the associated Polkadot interoperability and shared-security framework—not a guarantee that the chain’s product will succeed or that any token will rise in value.
Under the current model documented by the Polkadot Wiki’s Agile Coretime guide, non-system chains can acquire coretime in two ways: bulk or on demand. Coretime purchases use DOT, and the Wiki says the purchase tokens are burned. The exact price and sale conditions are market- and time-dependent; the available documentation here does not establish a live DOT price or a current coretime quote.
Bulk vs. on-demand coretime
The choice is mainly about how regularly a chain needs execution time and how much price predictability its team wants. The comparison below reflects the mechanisms described in the Wiki, not a claim that one option is always cheaper.

| Decision axis | Bulk coretime | On-demand coretime |
|---|---|---|
| Access pattern | Purchase coretime for a fixed period. | Order coretime when needed. |
| Price behavior | Fixed purchase price with predictable renewal pricing, according to the official guide. | Variable spot price that can depend on demand and other market conditions. |
| Planning fit | Often better suited to teams expecting sustained, regular relay-chain access. | Often better suited to intermittent or uncertain block-production needs. |
| Cost uncertainty | More predictable over the purchase period. | More exposed to variable pricing and demand. |
These are planning implications, not a break-even calculation. The documentation does not establish an amount at which one option becomes cheaper than the other, and a team’s actual choice depends on its usage pattern and the prices available when it buys.
When bulk coretime may fit
A chain expecting to produce blocks regularly may value having a fixed-period allocation and clearer renewal expectations. That can make capacity planning easier, though it does not eliminate the need to assess the purchase price and future renewal terms.
When on-demand coretime may fit
A chain with sporadic activity, or one that cannot justify continuous access, can buy coretime for blocks as needed. This model was previously described using the term “parathread”; the current documentation calls these on-demand parachains. It avoids paying for continuous core access, but variable spot pricing means the cost is less predictable.

How are system chains different?
Not every chain uses the same economic route. System chains provide network-level functions such as assets, identity, governance and bridging. The Polkadot Wiki defines them as chains that “contain core Polkadot protocol features, but in parachains rather than the relay chain.” Their execution cores are allocated through governance rather than purchased like non-system-chain coretime.

The Wiki says system chains generally do not have a native token or governance system separate from DOT. Their role is to provide shared network functions, so their core allocation is a governance matter rather than an ordinary commercial purchase.
How did parachain auctions and crowdloans work?
Before Agile Coretime, a project sought a core through a competitive lease auction. Crowdloans were one way teams gathered tokens from supporters to participate. That system tied access to a lease reservation; it is not the current mechanism for new core access.

According to the Polkadot Wiki’s auction-transition guide, lease auctions stopped on-chain on 19 September 2024, when runtime upgrade 1.2.0 was enacted. Existing active leases were automatically converted to bulk coretime. Leases that had not yet started were canceled, and their locked tokens were refunded.
The transition changed the unit teams manage: instead of competing for a long-term lease, they can purchase coretime in bulk or as needed. The Wiki presents greater flexibility—including the ability in some cases to split or interlace coretime—as a design goal. Those are descriptions of the system’s design, not independent measurements proving realized cost savings or efficiency gains.
What does this mean for the parachain economy?
Polkadot’s economic model separates network access from the economics of an individual application. Teams must plan for the cost and availability of execution time, while deciding independently whether their chain needs a token and how its application will attract users. Coretime is a network resource, not an investment thesis for a connected chain.

- For builders: estimate whether block production will be steady or intermittent, then weigh a fixed-period purchase against variable on-demand access.
- For users: understand that shared security and cross-chain infrastructure describe how chains connect; they do not establish a chain’s product quality or token value.
- For token holders: DOT has a role in non-system-chain coretime purchases, but this mechanism alone does not establish a market price or investment outcome.
Where can teams manage coretime?
The Polkadot Wiki names RegionX Hub as an interface for viewing, purchasing and managing coretime. It also names Lastic as a blockspace marketplace and describes functions including transferring, splitting and assigning coretime. These are third-party interfaces; their availability and features can change. Check their current documentation and functionality before relying on them.
What the available figures do—and do not—show
The historical transition date is clear: lease auctions stopped on 19 September 2024 with runtime upgrade 1.2.0, according to the Wiki. That date describes a protocol change, not a current market condition.
The Wiki’s onboarding guide also gives approximate registration figures of about 3,300 DOT for a Polkadot registration deposit and about 150 DOT in estimated fees, as well as about 1,100 KSM for a Kusama deposit and about 5 KSM in estimated fees. The guide does not state when those estimates were published. They concern registration—not the purchase price of current coretime—and should not be treated as verified current costs.
The cited official documentation explains the mechanism, but it does not establish an average coretime price, market size, chain revenue, or measured economic impact. Coretime prices, sale cadence, governance allocations and network functions may change over time.
