Polkadot moved from its 2020 relay-chain launch to coretime in 2024. It reports a 2.1 billion DOT cap from March 14, 2026, while official issuance figures conflict and JAM remains a proposed successor.
OriginTrail is a multi-chain Decentralized Knowledge Graph whose node software stores and serves structured knowledge while contracts anchor selected records and allocate TRAC publishing fees. The original 500 million-supply Ethereum TRAC is bridged to active DKG chains; NeuroWeb uses NEURO for gas, and current V10 documentation lists Base and Gnosis—not NeuroWeb—as selectable mainnets.
HDX crossed a chain migration and a rebrand without losing asset ID 0. Governance then cut its planned ceiling to 6.5 billion, minted nearly all remaining allocation into Treasury, and wrapped voting, revenue and liquidation risk together in GIGAHDX.
Kusama is a sovereign Polkadot-SDK network whose native KSM moved with balances, staking and OpenGov from the Relay Chain to Kusama Asset Hub in October 2025. KSM pays fees, secures validators, buys coretime and votes; it has no maximum supply, and current runtime parameters bound annual inflation between 2.5% and 10% around a 75% ideal stake ratio.
PEAQ is the native asset of a machine-focused Layer 1 that grew from three founders’ enterprise IoT work. Its 2024 launch brought real machine registrations, but peaq’s larger device counts remain project-reported ecosystem reach, while inflation and treasury control still sit inside a staged governance transition.
Astar began as Sota Watanabe’s Plasm Network, then outgrew a Layer-2 label and became a Polkadot application chain. Its unusual builder-staking economy survived a short-lived zkEVM expansion; Astar later closed that chain, carried ASTR into Sony and Startale’s Soneium, and kept native-chain governance distinct from the new bridge contract’s admin keys.
