Polkadot’s Relay Chain began producing blocks, starting the network’s staged rollout. Early on, governance and upgrades relied on a temporary superuser (“Sudo”) setup, which let the core team safely deploy and test major features before opening them to wider community control.
Polkadot carried out a 1:100 redenomination (often described as a “split”) of DOT, changing the unit size without changing holders’ overall value. This was meant to make DOT amounts easier to read and use in day-to-day staking, governance, and fees as the ecosystem matured.
Kusama (Polkadot’s “canary network”) started parachain slot auctions, giving teams and the community a real economic environment to test auctions, crowdloans, and parachain operations. This step helped validate processes before Polkadot ran auctions at larger scale.
Karura, a DeFi-focused network associated with the Acala team, won the first Kusama parachain auction. The result signaled strong demand for early DeFi infrastructure and showed that crowdloan-backed bidding could mobilize large community participation.
Polkadot’s on-chain governance approved the plan and schedule to begin parachain auctions. This was a key transition from “building core technology” to allocating scarce parachain slots—turning the ecosystem into a competitive marketplace for blockspace (execution capacity).
A runtime upgrade enabled the on-chain mechanisms needed for parachain registration and crowdloans (community DOT contributions locked for a lease term). This mattered because it turned parachain auctions into a practical, community-driven process rather than a purely team-funded competition.
Polkadot’s first parachain auction began, using a candle-auction style ending to reduce last-minute “sniping.” The auction format and crowdloan design linked early DeFi growth to community governance and token-locking, shaping how projects bootstrapped users and liquidity.
Acala won the first Polkadot parachain slot after a close contest, becoming an early centerpiece for Polkadot DeFi (including stablecoin and DEX ambitions). The win demonstrated the scale of crowdloans, with large amounts of DOT locked to support a DeFi-focused parachain.
Moonbeam won the second slot, bringing an Ethereum-compatible environment (EVM support) to Polkadot. This helped attract developers and users familiar with Ethereum tooling, which was important for early DeFi apps that wanted portability across chains.
Astar won the third slot, positioning itself as a smart-contract platform for decentralized applications on Polkadot. With multiple smart-contract and “app platform” chains emerging, the ecosystem began to look less like a single network and more like a connected set of specialized execution environments.
Parallel Finance won the fourth slot, highlighting demand for DeFi lending and capital-efficiency tools (borrowing, lending, and staking-related products). Together with Acala, this reinforced that early Polkadot growth was closely tied to DeFi primitives rather than consumer apps.
Clover Finance won the fifth slot, completing the first set of five weekly auctions. Finishing this batch gave Polkadot a diversified initial parachain set (DeFi hubs, EVM compatibility, smart-contract platforms, and finance protocols), setting the baseline for early cross-chain DeFi experimentation.
The first auction winners were scheduled to be onboarded together at the start of a lease period, and Polkadot began operating with multiple live parachains. This marked a practical “early DeFi ecosystem” phase: projects could run on their own chains while relying on the Relay Chain for shared security and coordination.
Polkadot continued auctions into 2022, adding more parachains beyond the first cohort. Winners included infrastructure and DeFi-adjacent networks such as HydraDX (liquidity/DEX focus) and Interlay (Bitcoin-related interoperability), showing a shift from “launching the first five” to broad ecosystem build-out.
