Kusama's most revealing experiment was no demo. It moved balances, staking and governance away from the Relay Chain while KSM remained economically live. The migration shows why “testnet” is the wrong word: holders finance each rehearsal and inherit its new architecture.
Web3 Foundation launched Kusama before Polkadot so unfinished technology could meet validators and capital. KSM holders later received on-chain control and the network stayed independent. Canary now describes release order and risk appetite, not a promise that Kusama will be discarded.
BABE and GRANDPA coordinate a nominated validator set. A bad validator can lose its own stake and the nominators exposed to it; an offline validator can miss rewards. Kusama learns from failures precisely because KSM locks, slashes and treasury choices are real.
KSM has no cap. Runtime source bounds inflation between 2.5% and 10%, targets 75% staked and uses a 5% falloff. Root governance can replace these parameters. A quoted annual yield is therefore a moment in staking participation and validator commission, not a permanent token promise.
The old Council and Technical Committee gave way to concurrent tracks. Each origin has distinct deposits, voting curves and enactment times; conviction can amplify a vote by extending its lock. The Fellowship's whitelist shortens the path for reviewed code, but cannot substitute for the referendum that authorizes execution.
KSM once became synonymous with crowdloans and fixed parachain leases. Agile Coretime shifted demand toward bulk regions and on-demand orders, with transition rules for existing leases. KSM still purchases shared computation, but the commercial object is schedulable coretime rather than a permanent parachain slot.
Kusama moved transferable KSM, staking and governance to Asset Hub. The Relay Chain retained consensus duties and receives validator-set information from the Asset Hub client. A relay-only explorer can now show only residual issuance; an Asset-Hub-only explanation can hide the chain that finalizes parachains. Both are pieces of one KSM system.
KSM lets a holder pay, stake, buy coretime, submit deposits and vote. It does not buy shares in Web3 Foundation or Parity, ownership of parachains, a dividend or a right to redeem at a fixed value. Software authors and the Fellowship influence what code reaches voters; OpenGov decides what authority the network grants it.
Kusama begins as an economically live proving ground before Polkadot.
The new referenda, conviction-voting and Fellowship structure begins replacing the Council model.
Bulk and on-demand coretime supplant the fixed-slot auction as the general resource model.
Transferable balances, staking and governance leave the Relay Chain for Kusama Asset Hub.

Kusama is a live, permissionless network built with the Polkadot SDK. It began in September 2019 as a canary release for Polkadot, but it has its own validators, treasury, OpenGov referenda, parachains and economically valuable native KSM. It is neither a disposable testnet nor a claim on DOT.
Since the October 2025 Asset Hub Migration, ordinary KSM balances, staking and governance live on Kusama Asset Hub while the Relay Chain continues consensus and parachain security. The same KSM economic system spans these system chains through XCM; Relay-Chain and Asset-Hub balances should not be read as two separate supplies.
A valueless testnet cannot reproduce validator incentives, treasury politics or the cost of a failed runtime upgrade. Kusama deliberately tests Polkadot-SDK changes under real economic conditions and shorter governance periods. Some teams later deploy related systems on Polkadot; others remain only on Kusama.
Its canary role does not make every change temporary or automatically copied to Polkadot. Kusama governance approved its own coretime, bridge and Asset Hub changes, and KSM holders bear the slashing, lock, upgrade and treasury consequences on their own network.
BABE authors blocks and GRANDPA finalizes them under nominated proof of stake. Validators operate infrastructure; nominators and pool members back validators with KSM. Rewards are not guaranteed, and offences can slash both validator and exposed nominator stake. Unbonding and conviction voting lock capital for protocol-defined periods.
KSM has 12 decimals and no maximum supply. The current runtime exposes dynamic inflation parameters: 2.5% minimum, 10% maximum, 75% ideal stake and 5% falloff. Governance Root can change inflation parameters. Issuance rewards staking security; depending on the staking rate, part of modeled inflation can flow to the treasury. This means current supply and yield must be read from chain state, not inferred from an ICO cap.
OpenGov replaces the old Council/Technical Committee model with parallel referendum tracks, conviction voting and delegation. Different origins have different deposits, approval/support curves and enactment periods. The Technical Fellowship can whitelist technically reviewed calls for a faster track, but the whitelist does not enact code by itself: KSM voting still decides the referendum. Root can dispatch runtime upgrades and change monetary parameters.
KSM also pays fees and purchases bulk or on-demand coretime for parachains. The older fixed parachain-slot auction and crowdloan narrative is no longer the general onboarding model after Agile Coretime. The trustless DOT-KSM bridge creates foreign representations on the opposite Asset Hub; bridged KSM is not new native issuance.
KSM conveys protocol participation, not equity in Web3 Foundation or Parity, dividends, guaranteed yield, redemption or ownership of a parachain. Runtime code is prepared by contributors and overseen in the Fellowship repository, then becomes network law only when the relevant on-chain origin enacts it.
No. It is a sovereign network with real KSM, validators, governance and treasury. It often deploys experimental Polkadot-SDK changes first, but its decisions and losses remain Kusama's.
Most transferable balances and the staking/governance functions moved to Kusama Asset Hub in October 2025. The Relay Chain still secures the network. Interfaces that inspect only one chain can show an incomplete balance or issuance figure.
No. The runtime issues KSM for staking according to governance-controlled parameters. Current source defines 2.5% minimum and 10% maximum inflation around a 75% ideal stake ratio.
OpenGov referenda can dispatch Root-level runtime upgrades and parameter changes when their track's approval, support, deposit and timing rules pass. Voting power can be delegated and increased through conviction locks.
No. It prepares and reviews runtime code and can whitelist a call for a faster OpenGov track, but the whitelisted referendum still needs KSM-holder approval.
That is now a historical generalization. Agile Coretime introduced bulk and on-demand coretime; older leases were migrated or refunded under transition rules.
No. Rewards vary with runtime parameters, era participation, validator commission and staking conditions. Slashing, downtime, unbonding and price risk can reduce the result.
No official source reviewed grants equity in Web3 Foundation or Parity, dividends, guaranteed revenue, redemption or ownership of a Kusama application.
