The Polkadot Playbook

The minimum set of information you need to be able to explain Polkadot to others.

What is Polkadot?

Polkadot is a scaling solution for Web3¹ applications and services.
Polkadot scales through data and execution sharding, allowing for parallelized throughput.²
Polkadot provides shared security and interoperability to services build 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

Build applications which execute automatically (without initial user input).
Build applications with full control over block construction and transaction execution.
Build applications which dynamically scale up and down execution cores.
Build applications which execute at sub-second speeds.⁶
Build applications where end-users pay no transaction fees.

Billions of dollars of economic security provided to itself and applications running on it.
Fast finalization times, on average under 30 seconds.
- Compare that to optimistic rollups which may take up to a week!
- Block production is separated from finality, reducing network stalls.⁷
Executing and scaling on standard "gaming" hardware.
- Compared to expensive and centralized machines needed for vertical scaling or ZK provers.
50+ active roll-ups building ⁸
- Many projects outside of Polkadot also use the Polkadot SDK.⁹
Secure cross-chain interoperability with a native bridging protocol.
Trustless bridges to other blockchain ecosystems.⁹

Among the highest Nakamoto coefficients in the blockchain ecosystem.¹⁰
2nd largest developer community after Ethereum.¹¹
Blazing fast execution speeds compared to other blockchain VMs.¹²
One of the largest functioning DAOs, managing tens of millions of dollars in assets.¹³
