Many specialised chains renting security from one shared validator set.
Polkadot's core idea is that individual chains should not each have to bootstrap their own validator set. A central relay chain provides security, and connected chains plug into it, inheriting that security while keeping their own logic. The contrast with Cosmos is instructive: Cosmos chains are sovereign and must secure themselves, Polkadot chains trade sovereignty for shared protection.
Shared security is a genuinely different bet from Cosmos-style sovereign chains.
The end of slot auctions changed DOT's demand mechanics substantially.
Governance here is real and binding, which cuts both ways.
Validators secure a relay chain, and connected chains submit their state to it for validation. Access to that shared security was originally auctioned through parachain slot leases, where projects locked DOT for a fixed period to win a slot. That model has since shifted toward a more flexible pay-as-you-go purchase of blockspace, which lowered the barrier for smaller teams but also removed the large DOT lockups that auctions produced.
Staking to secure the relay chain
Paying for blockspace used by connected chains
Direct on-chain governance and treasury voting
DOT is staked to secure the relay chain and used to pay for the blockspace connected chains consume. The shift away from slot auctions is the key thing to understand for value capture: auctions locked large amounts of DOT for years, while usage-based purchasing ties demand to actual consumption. That is healthier economically but removes a mechanical source of supply lockup.
Polkadot runs one of the most fully on-chain governance systems of any large network: DOT holders can propose and vote on protocol changes and treasury spending directly, with referenda executing automatically when they pass. There is no foundation veto over approved changes, which makes governance unusually consequential and also unusually exposed to voter apathy and whale influence.
Ecosystem adoption has lagged the technical ambition, with fewer high-usage applications than peers.
Ending slot auctions removed a large structural source of DOT lockup.
Inflationary staking rewards dilute holders who do not stake.
High technical complexity raises the barrier for developers and for users trying to evaluate it.
Connected chains give up sovereignty, which some teams prefer to keep.
