Polkadot is an open-source protocol that connects multiple specialized blockchains, allowing them to transfer any type of data or asset securely. It aims to create a decentralized internet, often called Web3. As a layer-0 metaprotocol, it supports a network of layer-1 blockchains known as parachains. Polkadot can update itself without hard forks through on-chain governance. It connects public and private chains, permissionless networks, and oracles, enabling trustless information sharing. The native token, DOT, has three main purposes: governance, staking, and bonding.

Polkadot was created by Dr. Gavin Wood, Robert Habermeier, and Peter Czaban, and is the flagship project of the Web3 Foundation. Gavin Wood is well-known as a co-founder of Ethereum, founder of Parity Technologies, and creator of the Solidity programming language. He also coined the term Web3. Robert Habermeier is a Thiel Fellow with expertise in blockchain and cryptography. Peter Czaban served as the Technology Director at Web3 Foundation, bringing experience from specialized fintech sectors.

Polkadot stands out due to its sharded multichain design, which allows parallel processing of transactions across multiple chains, improving scalability. Developers can easily create custom blockchains using the Substrate framework, and these chains can connect to Polkadot's network. The network is highly flexible, enabling automatic upgrades without forks. It features a user-driven governance system where all token holders can vote. Various participants like nominators, validators, and collators help secure and maintain the network. At the end of 2021, Polkadot held its first parachain auctions using a candle auction system.

After a network redenomination approved by referendum, one old DOT became 100 new DOT, increasing the initial maximum supply from 10 million to 1 billion tokens. This change was made to simplify calculations and did not affect holders' proportional ownership. Polkadot conducted its first ICO in October 2017, offering 2.24 million tokens at a price of $0.29 each. A second ICO in July 2020 sold 342,080 DOT at $1.25 per token.

Polkadot uses a nominated proof-of-stake (NPoS) mechanism involving validators and nominators. Nominators support validators by staking their tokens, which increases network security by making malicious actions costly. Validators are staked on the Relay Chain and verify transactions from parachains. This unique validity scheme allows chains to interact securely under shared rules while maintaining independent governance.

Polkadot (DOT) can be purchased on major exchanges such as Binance, Huobi Global, OKEx, Coinbase, and KuCoin. Coinasity lists the exchanges that trade DOT. Additionally, you can buy cryptocurrencies like Bitcoin and Ethereum directly with credit cards in your local fiat currency. To see the live DOT price in other currencies, you can use the Coinasity converter.
