Polkadot's Vision and Potential!

1. What is Polkadot?

Polkadot is a sharded blockchain based on the thesis that the world will have several blockchains that need to interact. Polkadot unites scalability, interoperability, and security.

The Polkadot network uses a sharded model where shards - called “parachains” - in the network have unique state transition functions (STF). Based on Polkadot’s design, as long as a chain’s logic can compile to Wasm, then it can connect to the Polkadot network as a parachain.

Polkadot has a Relay Chain acting as the main chain of the system. Parachains construct and propose blocks to validators on the Relay Chain, where the blocks undergo rigorous availability and validity checks before being added to the finalized chain. As the Relay Chain provides the security guarantees, collators don’t have any security responsibilities, and thus do not require a robust incentive system.

In order to interact with chains that want to use their own finalization process (e.g. Bitcoin), Polkadot has bridge parachains that offer two-way compatibility.

The Cross-Chain Messaging Protocol (XCMP) allows parachains to send messages of any type to each other. The shared security and validation logic of the Relay Chain provide the environment for trust-free message passing that opens up true interoperability

2. Polkadot Network

Dr. Gavin Wood, co-founder of Polkadot, explains the foundational principles of the network.

Björn Wagner, CCO from Parity Technologies LTD, developing partner of Web3 Foundation, the organization stewarding the Polkadot Project explains how different blockchains can communicate and operate with each other.

Marek Kotewicz from Parity Technologies is one of the lead developers of the Polkadot Network.

In this video, he explains how token holders have governance over the network and how the project aims to improve the issue of lack of scalability that affects the Blockchain space.

Peter Czaban (Web3 Foundation Council) explains how every Parachain in the Polkadot Network will enjoy the feature of pooled security, enabling all the chains in the ecosystem to leverage the overall network security.

What’s the difference between the mechanism that brings security and scalability to the Polkadot Network, and the model historically used by previous blockchains? Rob Habermeier from Parity Technologies, lead researcher of Polkadot, explains.

Dr. Gavin Wood explains the goals of the Web3 Foundation and the stewarding of the Polkadot protocol

The internet has been viewed as transformative for society. But we are still effectively applying the same old business models and hierarchical structures to new technology.

Dr. Gavin Wood, Founder of Web3 Foundation, Parity Technologies and Ethereum, explains why it’s important for the internet to evolve into a truly decentralised web in order to allow for entirely new societal structures to be created.
