Parachain governance is the system by which a network's stakeholders propose, deliberate, and enact changes to its protocol. Unlike traditional blockchains, parachains on Polkadot and Kusama inherit a sophisticated, modular governance framework from the Substrate blockchain framework. This framework is designed to be forkless, meaning protocol upgrades are enacted on-chain without requiring a hard fork. The core components include a public referendum system, a council of elected representatives, and a technical committee for emergency responses. Setting this up requires configuring several key pallets within your parachain's runtime.

A practical guide to implementing on-chain governance for parachains, covering the core components, configuration, and best practices for decentralized decision-making.
The primary governance module is the Referendum Pallet. It manages public voting on proposals, which can originate from the public, the council, or as a result of a prior referendum. Key parameters you must define include: LaunchPeriod (how often new referenda are created), VotingPeriod (duration of a vote), and EnactmentDelay (time between approval and execution). For example, a common configuration sets LaunchPeriod to 7 days and EnactmentDelay to 8 days, providing stability. Voting uses adaptive quorum biasing, where the passing threshold adjusts based on the proposal's origin, favoring council-backed measures.
The Council Pallet and Technical Committee Pallet provide additional layers of oversight. The council is an elected body that can propose referenda, veto dangerous public proposals, and manage the treasury. The technical committee, composed of the teams actively building the parachain, can fast-track emergency proposals. In your runtime/lib.rs, you must instantiate these pallets and wire them together. This involves setting membership rules, election periods, and defining the relationship between the council's Members origin and the referendum's ExternalOrigin.
Treasury management is integral to governance. The Treasury Pallet funds development through proposals that are approved by the council or via a community spend referendum. You must configure the ProposalBond (a deposit required to submit a spending proposal), SpendPeriod (how often funds are disbursed), and Burn percentage for unspent funds. A well-tuned treasury ensures resources are allocated efficiently while preventing spam. Governance also controls critical runtime upgrades via the Democracy Pallet and Scheduler Pallet, which schedule and execute approved set_code operations.
To implement this, your parachain's runtime configuration will include code similar to the following snippet, which configures the origins and tracks for governance:
rustparameter_types! { pub const LaunchPeriod: BlockNumber = 7 * DAYS; pub const VotingPeriod: BlockNumber = 7 * DAYS; pub const EnactmentDelay: BlockNumber = 8 * DAYS; pub const CouncilMotionDuration: BlockNumber = 5 * DAYS; } impl pallet_democracy::Config for Runtime { type LaunchPeriod = LaunchPeriod; type VotingPeriod = VotingPeriod; type EnactmentDelay = EnactmentDelay; // ... other associated types }
This defines the core timing parameters that control the governance lifecycle.
Best practices for parachain governance include starting with conservative parameters (longer voting periods) to ensure stability, clearly documenting proposal processes for the community, and utilizing the Polkassembly or Subsquare forums for off-chain discussion. It's also crucial to test all governance pathways on a testnet like Rococo or a local --dev node before launch. Effective governance balances community participation with efficient decision-making, enabling the parachain to evolve transparently and securely in response to its stakeholders' will.
Prerequisites
Before implementing a governance framework, you must establish the foundational technical and conceptual components of your parachain.
A functional parachain network is the essential substrate for governance. This requires a live parachain connected to a relay chain, typically Polkadot or Kusama, via a parachain slot. You must have the core runtime logic, including a pallet-democracy or custom governance pallet, deployed and operational. Ensure your chain's native token is minted and distributed, as it will serve as the basis for voting power and proposal deposits. The Substrate Developer Hub provides the primary resources for building this foundation.
Governance mechanisms are defined and enforced within the runtime. You will need to configure key parameters in your governance pallet, such as the minimum deposit to submit a public proposal, the voting period duration (e.g., 28 days), the enactment delay after a referendum passes, and the approval and support thresholds for passage. These are set using the Config trait of pallets like pallet-democracy and pallet-collective. For example, LaunchPeriod is set in blocks to define how often new public referenda are created.
An active, token-holding community is required to participate in the governance process. You must have a method for stakeholders to signal their intent, typically through wallet interfaces like Polkadot-JS UI. Developers should prepare by understanding the different proposal tracks (e.g., Root, Treasury, General Admin) and the lifecycle of a proposal: submission, deposit, preimage hashing, referendum, and enactment. Tools like substrate-api-sidecar can be used to query chain state and submit extrinsic calls programmatically.
Finally, establish clear documentation and communication channels. This includes a public repository for runtime upgrades (e.g., on GitHub), a forum for discussion (like Polkassembly), and a transparent process for encoding proposal details into preimages. The technical team should be proficient with sudo or Council commands to initiate the first governance upgrade, transitioning from centralized control to decentralized, on-chain governance as defined in your runtime's logic.
Setting Up a Governance Framework for Parachain Networks
A practical guide to implementing on-chain governance for parachains, covering key mechanisms, pallet integration, and best practices for decentralized decision-making.
Parachain governance enables a decentralized network of token holders and stakeholders to propose, vote on, and enact changes to the chain's parameters and logic. Unlike traditional blockchain forks, this process is coordinated and executed on-chain, ensuring upgrades are seamless and non-contentious. The core components of a Substrate-based governance system typically include a Treasury for funding proposals, a Council or Technical Committee for expert oversight, and a public referendum mechanism for final approval by token holders. This structure balances agility with broad consensus, allowing parachains to evolve without centralized control.
Implementing governance begins with integrating the necessary pallets into your parachain's runtime. The primary pallet is pallet-democracy, which handles public referenda. You must also integrate pallet-treasury to manage community funds and pallet-collective for a council or technical committee. Configuration involves setting critical parameters in your runtime/src/lib.rs file, such as the LaunchPeriod (time between referendum launches), VotingPeriod (duration of a vote), MinimumDeposit for proposals, and EnactmentDelay (time between a vote passing and execution). These values define the speed and security of your governance process.
A standard governance flow involves several stages. First, a user submits a proposal to the Democracy pallet, locking a deposit. The proposal then enters a pre-voting queue. For significant changes, it may require approval from a Collective (Council) before becoming a public referendum. Once a referendum is live, token holders vote using their locked funds, with conviction multipliers allowing them to weigh their vote by lock-up time. If the vote passes and any EnactmentDelay elapses, the proposal is automatically executed via the Scheduler pallet. This entire lifecycle is transparent and immutable on-chain.
Key technical considerations include vote weighting and constitution design. Substrate's pallet-democracy implements adaptive quorum biasing, where the passing threshold for a referendum can change based on who proposed it (e.g., a simple majority for public proposals vs. a super-majority against for council proposals). You must also decide on a constitution—a set of rules encoded as chain parameters—that defines minimum deposits, maximum vote periods, and treasury spend limits. Testing these mechanisms on a testnet like Westend is crucial before launch to ensure they are robust against spam and attack vectors.
For advanced governance, parachains can leverage OpenGov (Governance v2), a more granular and scalable system introduced by the Polkadot Relay Chain. OpenGov features multiple, parallel tracks with specialized functions (e.g., a Root track for major upgrades, a Treasury track for spending). Each track has its own parameters for approval curve, decision deposit, and enactment delay. Migrating to or designing with OpenGov in mind future-proofs your parachain, enabling more complex, community-led operations. The Polkadot Wiki provides the definitive reference for these evolving standards.

Common Implementation Mistakes and Fixes
Avoid critical errors when setting up on-chain governance for your parachain. This guide addresses frequent developer pitfalls in configuring Substrate's pallet-democracy, pallet-collective, and treasury systems.
This is often caused by an incorrectly configured Launch Period or Voting Period. In Substrate, the LaunchPeriod (in blocks) determines how often new public referenda are launched from the proposal queue. If it's set too high (e.g., 30 days worth of blocks), proposals may never advance. The VotingPeriod must also be long enough for token holders to vote.
Common Fixes:
- Check your chain's
runtime/src/lib.rsconfiguration forpallet_democracy::Config. - Ensure
LaunchPeriodis a reasonable value (e.g.,7 * DAYSfor a testnet). - Verify
VotingPeriodis set and thatFastTrackVotingPeriodis shorter for emergency motions. - Use

Setting Up a Governance Framework for Parachain Networks
A robust governance system is essential for decentralized parachain networks to manage upgrades, treasury funds, and parameter changes. This guide explains how to implement a multi-layered governance framework using Substrate's pallets.
Parachain governance typically involves multiple stakeholder groups: token holders, a technical council, and potentially a root super-user. The core mechanism is on-chain voting, where proposals are submitted, debated, and enacted via referenda. Substrate provides the foundational pallets: pallet-democracy for public referenda, pallet-council for expert oversight (often using pallet-collective), and pallet-treasury for fund management. The sudo pallet or pallet-collective with a TechnicalCommittee origin is used for emergency interventions or fast-tracked upgrades.
The standard flow begins with proposal submission. Any token holder can deposit funds to submit a public proposal to the Democracy pallet. For faster or more technical motions, the elected Council can create an external proposal with a lower voting threshold. Key parameters you must configure include: the LaunchPeriod (time between referenda), VotingPeriod (duration of a vote), EnactmentDelay (time between approval and execution), and minimum deposit amounts. These are set in your chain's runtime lib.rs file within each pallet's configuration trait (Config).
Here is a simplified example of integrating the democracy and collective pallets in a runtime. First, ensure they are in your construct_runtime! macro:
rustconstruct_runtime!( pub enum Runtime where Block = Block, NodeBlock = opaque::Block, UncheckedExtrinsic = UncheckedExtrinsic { // ... other pallets Democracy: pallet_democracy, Council: pallet_collective<Instance1>, Treasury: pallet_treasury, } );
Then, configure the Council as an Origin that can fast-track proposals in the Democracy pallet's config.
Advanced governance models incorporate adaptive quorum biasing and delegated voting. Adaptive biasing, used in Kusama and Polkadot, adjusts the passing threshold based on proposal type (e.g., a simple majority for positive turnout biasing, a super-majority against for negative turnout biasing). Delegated voting, via pallet-democracy's delegate function, allows less active token holders to assign their voting power to experts. You must also secure the upgrade pathway by phasing out the sudo pallet and transferring the Root origin's powers to the governance system, often via a pallet-collective with a TechnicalCommittee membership.
Finally, test your governance setup thoroughly on a testnet. Use the Polkadot-JS Apps interface to simulate proposal submission, voting, and enactment. Monitor key events like Proposed, Tabled, and Executed. Consider implementing pre-image hashing to save storage, where only the hash of a proposal is voted on until it passes. A well-tested governance framework ensures your parachain can evolve transparently and resiliently, balancing community input with technical oversight for critical runtime upgrades and treasury decisions.
Setting Up a Governance Framework for Parachain Networks
A robust governance framework is essential for managing the critical process of parachain slot lease renewals, ensuring network continuity and community alignment.
Parachain slot leases on networks like Polkadot and Kusama are secured through periodic auctions, typically lasting 96 weeks. A governance framework defines the on-chain processes and community mechanisms for deciding when and how to bid for renewal. This involves coordinating treasury funds, gathering community sentiment, and executing the technical bid. Without formal governance, projects risk missing renewal deadlines, which can lead to parachain downgrade to parathread status or complete disconnection from the relay chain, disrupting all on-chain operations and user access.
The core components of a renewal governance framework include a democratic voting system, a transparent funding mechanism, and clear execution logic. Many projects use their native governance pallet, such as the Polkadot SDK's pallet-democracy or pallet-collective, to create a referendum. This referendum proposes the action—like spending X DOT from the treasury to bid in auction Y. Voters, often token holders, then signal approval. The approved proposal automatically triggers a pre-configured batch transaction via the utility pallet to place the bid, minimizing manual intervention and failure points.
For technical implementation, a common pattern is to pre-fund a multisig treasury wallet controlled by the council or a dedicated treasury module. The governance proposal's execution call bundles the necessary operations. A simplified example of a call to place a bid might look like this in a Substrate runtime configuration:
rustlet call = Call::Crowdloan::contribute { index: PARA_ID, value: BID_AMOUNT, signature: None, }; let batch_call = Call::Utility::batch_all { calls: vec![call.into()] };
This ensures the entire operation—fund allocation and auction participation—is atomic.
Effective frameworks also incorporate contingency plans. This includes setting up alert systems for auction start dates, establishing a fallback funding source (like a dedicated wallet separate from the main treasury), and defining emergency governance procedures for fast-track votes. Projects should regularly simulate the renewal process on a testnet like Westend or Rococo to validate the governance calls and ensure signers are available. Documenting this process in the project's wiki or governance repository is critical for transparency and operational resilience.
Ultimately, a well-designed governance framework transforms parachain slot renewal from a high-risk administrative task into a predictable, community-driven protocol. It aligns incentives, safeguards network membership, and demonstrates a project's long-term commitment to its ecosystem. For developers, integrating these mechanisms early in the parachain's lifecycle is a best practice for sustainable operation on leased security networks.
Frequently Asked Questions
Common technical questions and solutions for developers implementing governance on Substrate-based parachains.
In Substrate's governance pallets, Referendums and Council proposals are distinct decision-making tracks with different thresholds and use cases.
A Referendum is a direct, on-chain vote open to all token holders. It requires a significant portion of the network's stake to participate and pass. This is typically used for major protocol upgrades, like runtime migrations or changes to core pallets.
A Council proposal is a more agile, representative process. A council of elected members can propose and vote on actions. If approved, the proposal enters a Council Majority phase, where token holders can veto it, or a Technical Committee fast-track. This track is suited for operational decisions, treasury spending, or urgent bug fixes where full referendum turnout is impractical.
Key Distinction: Referendums are for broad consensus; Council proposals are for efficient, delegated decision-making.
Conclusion and Next Steps
This guide has outlined the core components for establishing a robust governance framework for a parachain network, from proposal systems to treasury management and on-chain voting.
Successfully deploying a governance framework is not the end, but the beginning of a continuous process. The initial parameters you set—like voting periods, approval thresholds, and deposit requirements—must be actively monitored. Use on-chain analytics from tools like SubQuery or Subscan to track proposal volume, voter turnout, and treasury expenditure. Be prepared to submit follow-up proposals to adjust these parameters based on real-world usage and community feedback, ensuring the system remains efficient and resistant to manipulation.
The security and decentralization of your governance are paramount. Next, consider implementing multi-signature safeguards for the treasury or a technical committee with time-limited abilities to fast-track emergency upgrades. For parachains built with Substrate, explore advanced pallets like Conviction Voting for vote locking or Origins to create complex permission structures. Always conduct thorough testing of new governance logic on a testnet like Rococo before proposing a runtime upgrade to your mainnet.
To foster a healthy ecosystem, focus on community engagement and education. Create clear documentation for your governance process on platforms like GitBook. Use off-chain signaling tools such as Polkassembly or Commonwealth for pre-proposal discussions to gauge sentiment. Encourage delegation by building user-friendly interfaces that explain the role of democratic councils and expert delegates. The goal is to transition from a developer-led chain to a community-owned network where stakeholders are empowered to guide its future.
