Know the backstory

May 2020 — Polkadot mainnet launch

Built by: Gavin Wood, Parity Technologies, and the Web3 Foundation

Polkadot was designed as a multi-chain system: a relay chain coordinates security and connected parachains handle specialized work.

Why it stands apart

A network designed to connect blockchains.

Rather than one chain doing everything, Polkadot's architecture aims to let multiple chains interoperate with shared security.

Bottom line: Polkadot has its own design, trade-offs, and risks. Learn the network before you use the asset.

Follow the money

What happens after you hit send.

Users submit transactions to the relevant Polkadot ecosystem chain.
Validators secure the relay chain through nominated proof of stake.
Parachain activity is validated and coordinated through the relay-chain system.

Know the economics

Where new DOT comes from.

DOT does not use a fixed maximum-supply model; its economics include inflation and staking incentives.

Protect the downside

The mistake you cannot undo.

Different parachains, wallets, and asset locations can be confusing. Confirm the destination chain and address format before every transfer.

Go beyond the summary

The subject in plain English.

Polkadot is a separate system with its own rules, people, and trade-offs. This page explains the basics in plain English so you can understand it before deciding whether to use it.

Start with the plain version

Its birthday and backstory

May 2020 — Polkadot mainnet launch. Polkadot was designed as a multi-chain system: a relay chain coordinates security and connected parachains handle specialized work.

Who is behind it?

Gavin Wood, Parity Technologies, and the Web3 Foundation. Names can explain a project’s history, but they do not make an asset safe or guarantee its future.

What keeps the record

Polkadot uses Nominated Proof of Stake. Validators secure the relay chain, while connected chains can handle their own specialized activity.

Supply, fees, and incentives

DOT does not use a fixed maximum-supply model; its economics include inflation and staking incentives.

The part to take seriously

Different parachains, wallets, and asset locations can be confusing. Confirm the destination chain and address format before every transfer.

What people use it for

Where this matters.

Learn how the network records activity
Understand the difference between the asset, the network, and the company around it
Recognize the correct network before a transfer
Check whether a wallet or service actually supports this asset

Before you act

Verify before you sign.

Find the project through an official link, not an ad, reply, or direct message.
Confirm the exact name, ticker, network, and token or contract address.
Do not share a recovery phrase, private key, or remote access with anyone.
Use a small test transaction before moving an amount that matters.
Treat every purchase, yield offer, or app approval as a separate risk decision.
