The Polkadot Playbook

Simple, accurate answers to common questions about Polkadot, backed by extensive references and source material, empowering anyone to become a Polkadot ambassador.

What is Polkadot?

  • Polkadot is a cloud server for Web3 applications and services.1
  • Polkadot scales through data and execution sharding, allowing for parallelized throughput.2
  • Polkadot provides shared security and secure interoperability to services built on it.3
  • Polkadot creates abundant, flexible, and high quality blockspace.4
  • Polkadot uses a novel "cynical" rollup to provide fast finality while using minimal resources.5

What unique things can you do on Polkadot?

  • Build applications with full control over block construction and transaction execution.6
  • Build applications with full control over fees, fee payments, and tokens.7
  • Build applications which dynamically scale up and down execution cores.8
  • Build applications which execute at sub-second speeds.9
  • Build applications that can permissionlessly upgrade and evolve over time.10

Why choose Polkadot?

  • Billions of dollars of economic security provided to itself and applications running on it.11
  • Fast finalization times, on average under 30 seconds.12
  • Executing and scaling on standard "gaming" hardware.13
  • Polkadot SDK is the most robust and flexible blockchain framework.14
  • Secure cross-chain interoperability through trustless bridging protocols.15

Where is Polkadot leading?

  • 50+ active rollups live on Polkadot driving 32M transactions across 200K active accounts per month.16
  • Among the highest Nakamoto coefficients in the blockchain ecosystem.17
  • One of the largest developer community after Ethereum.18
  • Blazing fast execution speeds compared to other blockchain VMs.19
  • One of the largest functioning DAOs, managing the functionality of the network and $150M dollars in assets for development.20

How Polkadot is better than...

  • Ethereum: Polkadot realized Ethereum's scaling vision first, conceived and delivered by co-founder Dr. Gavin Wood.21
  • Solana: Unlike Solana, Polkadot scales without compromising Web3 principles of decentralization and security.22
  • Cosmos: Unlike Cosmos, Polkadot provides shared security and secure interoperability.23
  • Avalanche: Subnets in Avalanche are not as flexible as applications on Polkadot, and subnets do not provide shared security or secure interoperability.24
  • Layer 2s: Layer 2 solutions face performance issues, unpredictable fees, and fragmented interoperability due to non-native support for rollups.25

Footnotes

  1. Learn more about Web3:

    ↩

  2. Explanation of sharding on Polkadot: https://polkadot.com/blog/polkadot-v1-0-sharding-and-economic-security ↩

  3. A high level overview of shared security: https://www.youtube.com/watch?v=uKQOSPfM-W0 ↩

  4. A blog post explaining the term "blockspace": https://www.rob.tech/blog/polkadot-blockspace-over-blockchains/ ↩

  5. Polkadot's cynical rollup protocol is called ELVES.

    ↩

  6. For example:

    • Build applications more resilient to MEV.
    • Build applications which can prioritize certain tasks and processes.
    • Build applications which only execute when it is economical to do so.
    ↩

  7. For example:

    • Build applications where end-users pay no transaction fees.
    • Build applications which can accept fees paid in any token.
    • Build applications where users need not hold DOT or your native token to hold other tokens.
    ↩

  8. Learn more about Agile Coretime:

  9. A demo of a Polkadot SDK blockchain producing blocks every .5 seconds: https://twitter.com/bkchr/status/1818027282688352591 ↩

  10. Learn about forkless runtime upgrades in Polkadot: https://wiki.polkadot.network/docs/learn-runtime-upgrades ↩

  11. Polkadot's economic security can be measured by multiplying the total market cap of the DOT token by the percentage of DOT token locked in Polkadot's Nominated Proof-of-Stake protocol.

    ↩

  12. Learn more about cynical rollups:

    • Compare that to optimistic rollups which may take up to a week to finalize!
    • Cynical rollups actively check that a block is valid, rather than waiting for someone to report it is invalid. See ELVES paper footnote above.
    • Compared to "instant finality" consensus, block production is separated from finality, reducing network stalls: https://polkadot.com/blog/polkadot-consensus-part-1-introduction
    ↩

  13. Compared to expensive and centralized machines needed for vertical scaling or ZK provers.

    ↩

  14. Polkadot SDK is used throughout the entire blockchain ecosystem:

    • Polkadot and Kusama are built with the Polkadot SDK.
    • All 50+ live parachains, and many more in development, all use Polkadot SDK.
    • Many projects outside of Polkadot also use the Polkadot SDK: Avail, Cardano, Entropy, and more...
    ↩

  15. Bridging in Polkadot can be broken down into internal bridges and external bridges:

What's inside

5 question sections with bullet-point answers, each backed by footnoted references (55 footnotes total).

Change this for your project

  • Replace footnote URLs like https://polkadot.com/blog/polkadot-v1-0-sharding-and-economic-security with your own sources
  • Replace https://twitter.com/... and https://x.com/... links with current or alternative references
  • Replace https://wiki.polkadot.network/docs/... links if using a different wiki or version

Where it goes

Keep it in your repository where the agent or team that needs it will read it.

Worth borrowing

  • Using footnotes to keep claims concise while providing deep citations
  • Structuring each section as a clear question with a short answer and then a comparison or example
