What is Polkadot?
Polkadot is a blockchain network that connects multiple specialised blockchains. It is designed to allow these blockchains to communicate with each other and share data, which can help to improve scalability, security, and interoperability.
How does it work?
Polkadot is a sharded blockchain, which means that it is divided into smaller pieces called shards. Each shard is responsible for processing a subset of the network’s transactions. This allows Polkadot to scale to handle a large number of transactions without sacrificing security or decentralization.
Polkadot also uses a proof-of-stake consensus mechanism, which means that validators are chosen based on their stake in the network. This makes Polkadot more secure than proof-of-work blockchains, such as Bitcoin, because it is less susceptible to attacks by miners with a large amount of computing power.
The native currency of Polkadot is called DOT. DOT is used to secure the network, participate in governance, and pay for transaction fees.
How can Polkadot help you?
Polkadot can help you in a number of ways, including:
- Sending and receiving payments: You can use Polkadot to send and receive payments to anyone in the world, without the need for a bank or other financial institution.
- Creating smart contracts: You can use Polkadot to create smart contracts, which are like computer programs that run exactly as they are programmed. Smart contracts can be used to automate a wide variety of tasks, such as making payments, managing contracts, and verifying identities.
- Building decentralised applications (DApps): You can use Polkadot to build decentralised applications (DApps). DApps are applications that run on the Polkadot blockchain, and they are not subject to the control of any single entity. This makes them ideal for applications that require trustless execution, such as financial services, gaming, and supply chain management.

What are the benefits of using Polkadot?
There are a number of benefits to using Polkadot, including:
- Scalability: Polkadot is designed to be scalable, so it can handle a large number of transactions. This makes it ideal for applications that require a high volume of transactions, such as financial services and gaming.
- Security: Polkadot is a secure platform, and its smart contracts are verified by the Polkadot Virtual Machine (PVM). This makes it less likely that your funds will be lost or stolen.
- Interoperability: Polkadot is designed to be interoperable with other blockchains. This means that you can easily transfer assets between Polkadot and other blockchains.
- Decentralisation: Polkadot is a decentralised platform, which means that it is not controlled by any single person or organisation. This makes it more secure and resistant to censorship.
Who is behind Polkadot?
Polkadot was founded by Gavin Wood, who is also the co-founder of Ethereum. Wood is a well-respected figure in the blockchain community, and he has a proven track record of success.
