Price movement: ATOM and DOT
The start of the period is taken as 100 for both prices: the chart shows the difference in movement, not the quotes themselves.
| Period | ATOM | DOT |
|---|---|---|
| 7 days | −4.43% | +2.12% |
| 30 days | +15.22% | +51.78% |
| 90 days | +14.53% | +50.22% |
The link between their daily moves over the quarter is 0.51 (they travel alike).

How Cosmos and Polkadot are built
How Cosmos works
The Cosmos Hub stands on Proof of Stake with the CometBFT consensus (formerly named Tendermint), and a block comes out within seconds. Networks built on the Cosmos SDK send tokens to each other over the IBC protocol. Unbonding staked ATOM drags on for 21 days.
What Cosmos is for
ATOM goes towards staking, governance and Cosmos Hub fees, and it moves between Cosmos blockchains over IBC.
How Polkadot works
The design has two levels: a relay chain holds the shared security, and parachains connect to it. The consensus is Nominated Proof of Stake, with a block every 6 seconds. Staked DOT cannot be transferred straight away: an unbonding period comes first.
What Polkadot is for
DOT is needed for staking, network governance and for connected chains to obtain blockspace.
