 ## What is Polkadot?
 
-- Polkadot is a scaling solution for Web3 applications.
-- Polkadot scales through data and execution sharding, allowing for parallelized throughput.
-- Polkadot provides shared security and interoperability to services build on it.
-- Polkadot creates abundant, flexible, and high quality blockspace.
-- Polkadot uses a novel "cynical" rollup to provide fast finality while using minimal resources.
+- Polkadot is a scaling solution for Web3[^1] 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]
 
-## Why choose Polkadot?
-
-- On average, blocks are finalized in under 30 seconds.
-	- Compare that to optimisic rollups which may take up to a week!
-- Executing and scaling on standard "gaming" hardware.
-	- Compared to expensive and centralized machines needed for vertical scaling or ZK.
-- 50+ active roll-ups building
-- Billions of dollars of economic security provided to itself and applications running on it.

-## What can you do on Polkadot?
+## What unique things can you do on Polkadot?
 
 - 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
+- Build applications which execute at sub-second speeds.[^21]
 - 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.[^31]
+- 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 [^32]
+	- Many projects outside of Polkadot also use the Polkadot SDK.[^33]
+- Secure cross-chain interoperability with a native bridging protocol.
+- Trustless bridges to other blockchain ecosystems.[^33]
+
 ## Where is Polkadot leading?
 
-- Among the highest Nakamoto coefficients in the blockchain ecosystem. [[Source][1]]
-- 2nd largest developer community
+- Among the highest Nakamoto coefficients in the blockchain ecosystem.[^41]
+- 2nd largest developer community after Ethereum.[^42]
+- Blazing fast execution speeds compared to other blockchain VMs.[^43]
+- One of the largest functioning DAOs, managing tens of millions of dollars in assets.[^44]
