Polkadot and Web3 Foundation in Zug: Switzerland's Role in Building the Blockchain of Blockchains

The Web3 Foundation: Zug’s Protocol Governance Engine

The Web3 Foundation (formally: Web3 Foundation) is a Swiss Stiftung — a foundation under Swiss law — registered in Zug, Switzerland. It was established in 2017 by Gavin Wood (Ethereum co-founder and author of the Polkadot whitepaper), Peter Czaban, and Aeron Buchanan, with the stated purpose of facilitating a fully functional and user-friendly decentralised web.

Key Data (as of 2025):

The Web3 Foundation chose the Swiss Stiftung structure for the same reasons that the Ethereum Foundation, Cardano Foundation, and Tezos Foundation chose it: no shareholders, a clear purpose mandate, cantonal supervisory oversight, and the legal capacity to hold substantial token treasuries without corporate equity complications. The DOT token — which Polkadot’s on-chain treasury and foundation hold in significant quantity — is most cleanly governed through a Swiss foundation structure.

The Foundation’s relationship to Polkadot’s development follows the Crypto Valley model: the foundation governs, holds treasury, and funds ecosystem development; a separate engineering company — Parity Technologies — builds the protocol. This separation is legally, operationally, and philosophically deliberate.

Origins: The 2016 Whitepaper and the 2017 ICO

Gavin Wood published the Polkadot whitepaper in October 2016, while still processing his departure from Ethereum. The paper described a “heterogeneous multi-chain framework” — a relay chain architecture in which many independent blockchains could share security and communicate natively, without the trust assumptions required by cross-chain bridges on existing architectures.

The architecture addressed what Wood and others perceived as fundamental limitations of the single-chain model: Ethereum could execute smart contracts but could not specialise. A single chain must make tradeoffs between throughput, security, and decentralisation that apply to every application using it. Wood’s proposal was to separate the security layer (the relay chain) from the application layer (parachains), enabling each parachain to optimise for its specific use case while inheriting relay chain security.

In October 2017, the Web3 Foundation conducted a token sale for DOT, raising $145 million in ETH — one of the largest fundraises in the 2017 ICO wave. The raise established the Foundation’s treasury and provided the capital for multi-year protocol development. Parity Technologies — which Wood had co-founded in 2015 — became the primary technical delivery partner.

The Polkadot Architecture

Relay Chain

The relay chain is Polkadot’s central coordination mechanism. It provides:

Shared security: Validators on the relay chain are responsible for validating blocks from all parachains. A parachain team does not need to recruit and maintain its own validator set — it inherits relay chain security, which is backed by the full DOT staking pool.

Cross-chain messaging: The XCMP (Cross-Consensus Message Passing) protocol enables parachains to send assets and arbitrary data to each other, with the relay chain providing routing and ordering guarantees.

Finality: The relay chain uses GRANDPA (GHOST-based Recursive ANcestor Deriving Prefix Agreement) for finality — a voting-based finality protocol that can finalise large numbers of blocks quickly. Combined with BABE (Blind Assignment for Blockchain Extension) for block production, Polkadot achieves faster finality than Ethereum’s proof-of-stake implementation.

Governance execution: The relay chain executes governance decisions — including runtime upgrades — directly on-chain, enabling Polkadot to upgrade its own logic without hard forks.

Parachains

Parachains are the application layer. Each parachain is an independent blockchain with its own logic, token, governance, and state — but it connects to the relay chain and inherits its security.

Parachains are designed for specialisation. Examples from the live Polkadot ecosystem:

• Moonbeam: An Ethereum-compatible parachain, enabling Solidity smart contracts within the Polkadot ecosystem
• Acala: A DeFi hub parachain, providing stablecoin (aUSD), liquid staking, and AMM functionality
• Phala Network: A privacy-preserving computation parachain using Trusted Execution Environments
• Centrifuge: A real-world asset tokenisation parachain, connecting traditional finance assets to DeFi liquidity

This specialisation — impossible on a single-chain architecture — is Polkadot’s core value proposition. Each parachain can optimise its block time, finality mechanism, fee structure, and governance for its specific application domain.

Parachain Slot Auctions and Crowdloans

Parachains connect to the relay chain by leasing a “slot” — a 96-week period during which the parachain maintains a connection to the relay chain. Slot auctions ran from 2021 onwards, with projects bidding DOT to secure slots. The candle auction mechanism (ending at a random point within a window) prevented gaming by requiring bids to remain valid across an uncertain window.

Crowdloans were the mechanism by which parachain teams raised DOT for their auctions: DOT holders could lock DOT in a crowdloan module, which would contribute the DOT to the auction on the parachain’s behalf. Crowdloan contributors received parachain-native tokens as rewards. The crowdloan mechanism distributed DOT widely (hundreds of thousands of contributors for major auctions like Moonbeam and Acala) and created the broad community bases that sustain parachains.

As Polkadot evolved, the slot auction model was replaced by Agile Coretime — a more flexible resource allocation model introduced through governance in 2024, enabling parachains to purchase block execution time on a more granular basis rather than through 96-week slot leases.

DOT Tokenomics

DOT is Polkadot’s native token. It serves three primary functions:

Governance: DOT holders participate in Polkadot’s on-chain governance, voting on proposals that range from treasury spending to runtime upgrades. Governance weight is proportional to DOT locked for voting (with conviction multipliers for longer lock periods).

Staking: DOT holders can nominate validators by staking DOT. Nominated validators receive block rewards; nominators share in those rewards in proportion to their stake. The staking mechanism secures the relay chain — currently approximately 40-60% of circulating DOT is staked at any given time.

Coretime: Under the Agile Coretime model, parachain teams use DOT to purchase relay chain execution time for their chains.

DOT’s supply is inflationary: new DOT is minted as staking rewards. The target inflation rate is approximately 10% annually, distributed to stakers and the on-chain treasury. Non-staked DOT is diluted; the inflation mechanism creates an economic incentive to stake rather than hold idle.

The Web3 Foundation holds a significant DOT treasury — the precise amount is public on-chain but subject to change with each treasury spend proposal. The Foundation’s DOT holdings fund grants, ecosystem development, and long-term protocol investment.

OpenGov: Conviction Voting and Referenda Tracks

Polkadot’s governance system underwent a major transformation with the deployment of OpenGov in 2023, replacing the previous bicameral governance model (Council + Technical Committee) with a fully on-chain, permissionless governance system.

Referenda Tracks

OpenGov organises governance proposals into “tracks” — categories with different parameters for voting periods, approval thresholds, and enactment delays. Tracks correspond to the sensitivity of the action being proposed:

Root: The highest-privilege track. Can execute any action on the relay chain, including runtime upgrades. Requires very high approval and support thresholds over a long voting period (28 days), with a 28-day enactment delay.

Whitelisted Caller: For time-sensitive technical upgrades endorsed by the Technical Fellowship. Faster voting period with the Fellowship’s endorsement providing part of the approval threshold.

Treasurer: For treasury spends above a certain threshold. Standard voting period with higher approval threshold.

Small Spender / Medium Spender / Big Spender: Tiered tracks for treasury expenditures of different sizes. Smaller spends have faster approval processes; larger spends require longer deliberation and higher thresholds.

General Admin, Referendum Canceller, Referendum Killer: Tracks for governance maintenance actions.

Conviction Voting

OpenGov’s most innovative feature is conviction voting. Rather than one-token-one-vote, conviction voting allows DOT holders to multiply their vote weight by locking their tokens for a longer period:

Conviction voting creates alignment between governance participation and long-term commitment: voters who believe most strongly in a proposal’s importance can amplify their vote at the cost of illiquidity. It also mitigates governance attacks that require rapidly acquiring and voting large token positions.

The Technical Fellowship

The Technical Fellowship is an on-chain body of Polkadot technical experts that maintains the Whitelisted Caller track — enabling faster execution of technical changes that have expert endorsement. Fellowship membership is managed on-chain through a governance process, with members ranked by their contributions. The Fellowship replaced the previous Technical Committee with a more meritocratic, scalable structure.

JAM: The Grey Paper and the Next Architecture

In 2024, Gavin Wood published the JAM (Join-Accumulate Machine) grey paper — a detailed technical specification for a proposed evolution of the Polkadot relay chain. JAM represents a significant architectural refinement:

In-core computation: JAM introduces a model where computation can happen “in-core” (within the validator’s execution environment, essentially in the relay chain’s validation process) rather than requiring separate parachain infrastructure. This enables a broader class of applications to access Polkadot’s shared security at lower cost.

The Join-Accumulate model: JAM proposes a computation model based on two operations: “join” (gathering inputs for a computation from the network) and “accumulate” (executing the computation and writing results to the relay chain state). This model generalises the parachain concept — JAM services (analogous to parachains but more flexible) can implement diverse computation patterns rather than requiring the full blockchain execution environment that parachains need.

Backwards compatibility: JAM is designed to maintain backwards compatibility with existing parachains — existing Polkadot ecosystem projects would continue to function.

JAM is the subject of a public specification process and ecosystem-wide testing. Its deployment timeline depends on governance approval through the OpenGov process — which itself is a demonstration of Polkadot’s forkless upgrade philosophy in practice.

Kusama: The Canary Network

Kusama is Polkadot’s canary network — a live, value-bearing blockchain that runs a near-identical codebase to Polkadot but with faster governance parameters and lower barriers to parachain access. Kusama is used by the ecosystem for two purposes:

Protocol testing: New Polkadot features — including OpenGov, Agile Coretime, and components of the JAM transition — are deployed on Kusama first. Kusama’s faster governance cycles (7-day voting periods vs Polkadot’s 28-day periods) enable faster feedback on protocol changes.

Application development: Projects building for Polkadot often launch on Kusama first, using it as a production environment with lower economic stakes than Polkadot mainnet. Kusama’s parachain ecosystem includes projects that have subsequently graduated to Polkadot, as well as projects that have chosen to remain on Kusama permanently due to its lower costs and faster experimentation cycles.

KSM (Kusama’s native token) has its own market cap and is freely tradeable. The Web3 Foundation holds KSM in proportion to its DOT holdings and applies the same governance philosophy to both networks.

Web3 Foundation Grants Programme

The Web3 Foundation Grants Programme is one of the most significant ecosystem development initiatives in blockchain. As of 2025, the Foundation has disbursed over $75 million to 750+ grantees across the Web3 and Polkadot ecosystem.

Grant Categories

Research grants: Academic and institutional research into cryptography, distributed systems, and blockchain economics relevant to Polkadot’s development.

Infrastructure grants: Development of tooling, clients, SDKs, and infrastructure that improves the Polkadot developer experience.

Application grants: Projects building applications on Polkadot or Kusama — DeFi protocols, NFT platforms, identity systems, cross-chain bridges, governance tooling.

Maintenance grants: Ongoing support for critical infrastructure projects that require sustained development effort beyond initial delivery.

Grant Process

Grant applications are public — submitted through the Foundation’s public GitHub repository — and are reviewed by the Foundation’s technical team. Accepted grants are delivered in milestones, with payment contingent on delivery of defined technical outputs. The milestone-based structure ensures accountability and has been cited by other blockchain foundations (including the Ethereum Foundation’s ESP programme) as a model for transparent ecosystem funding.

The Foundation’s grant process does not require equity, token allocation, or governance rights in grantee projects — grants are pure ecosystem investment, reflecting the Swiss foundation model’s non-profit, purpose-driven character.

Ecosystem Scale and Positioning

Polkadot’s ecosystem, as of 2025, includes:

• 500+ projects building on Polkadot or Kusama
• 30+ active parachains on the Polkadot relay chain
• $5B+ in total value locked across the ecosystem at peak
• DOT market capitalisation consistently in the top 15 globally

The concentration of Polkadot’s governance and ecosystem development in Zug — through the Web3 Foundation’s registered office and Parity Technologies’ headquarters — makes the canton the operational centre of one of the world’s most significant blockchain networks. The grants programme, the Foundation’s regulatory engagement with FINMA, and the legal structure of the Stiftung are all products of Zug’s Crypto Valley ecosystem model.
