Polkadot is a multi-chain framework composed of relay chains and parachains, aiming to improve the interoperability and scalability of blockchains. 1. The relay chain is responsible for network security and cross-chain communication; 2. Parallel chains are customizable independent blockchains that share the security of the relay chain; 3. Parallel threads provide on-demand security services for low-cost and flexible access chains. In addition, Polkadot was founded by Ethereum co-founder Gavin Wood and supported by the Web3 Foundation and Parity Technologies. As a mainstream project, Polkadot has four major characteristics: high market value, active ecosystem, technological innovation and a huge developer community, covering multiple fields such as DeFi, NFT, and gaming, and promoting the development of the next generation of blockchain.

1. What is Polkadot's cross-chain protocol?

Polkadot is not a single-chain system in the traditional sense, but a multi-chain framework. Its core is a main chain called "Relay Chain" and multiple "parachans" connected to the relay chain.

• Relay chain: Responsible for the security, consensus and cross-chain messaging of the entire network. It does not carry application logic, but provides a unified underlying infrastructure.
• Parachains: These are independent blockchains that can be customized to run their own logic and applications according to specific needs. Parachains share security through relay chains and can communicate with other parachains. For example, a parachain might be specifically used for decentralized finance (DeFi), another might be used for gaming, and some might be used for authentication.
• Parathreads: For blockchains that do not need to be continuously connected to the relay chain, Polkadot also provides the concept of parallel threads, which can rent relay chains on demand for security, lower cost and higher flexibility.

This design allows Polkadot to achieve high scalability and interoperability. Different parachains can process transactions in parallel, thereby improving the throughput of the overall network. At the same time, through relay chains, information and value can be transmitted between parachains and external blockchains (through "bridges"), truly realizing the vision of "seamless connection between chains". Simply put, it is like a router, connected to a "local area network" with various functions, allowing information to freely shuttle between these networks.

2. Who is the founder of Polkadot?

Polkadot was founder of Dr. Gavin Wood . His background and experience are well-known in the blockchain field.

• Ethereum Co-founder: Gavin Wood is one of the eight co-founders of Ethereum and the chief technology officer (CTO) of Ethereum. He played a key role in the early development of Ethereum and wrote the Ethereum Yellow Paper, a detailed technical specification document.
• Solidity Language Designer: He is also the creator of the smart contract programming language Solidity. Solidity is the most commonly used smart contract language in the Ethereum ecosystem, and countless decentralized applications (DApps) and tokens are written in Solidity.
• Founder of Web3 Foundation: After leaving Ethereum, Gavin Wood founded the Web3 Foundation, an organization dedicated to promoting the development of decentralized Internet (Web3). Polkadot is one of the core projects funded and incubated by the Web3 Foundation.
• Founder of Parity Technologies: He also founded Parity Technologies, a leading blockchain infrastructure company that provides technology development and support for the Polkadot ecosystem. The company also developed tools such as the Parity Ethereum client.

Dr. Gavin Wood has a deep understanding and forward-looking insight into blockchain technology. He founded Polkadot to solve the challenges faced by early blockchains such as Ethereum in terms of scalability, interoperability and governance, and further promote the implementation of Web3.

3. Is Polkadot the mainstream?

Yes, from multiple dimensions, Polkadot is undoubtedly a mainstream project in the blockchain field. It has significant influence and recognition in the industry.

1. Market value and attention: Polkadot's crypto asset DOT has long been at the forefront of the global cryptocurrency market value rankings, which directly reflects its market recognition and user attention. Its price volatility and technological progress have both received close attention from a large number of investors and the media.
2. Ecosystem Construction: Polkadot has an increasingly powerful and vibrant ecosystem. Up to now, hundreds of projects have been developed and deployed based on Polkadot or its brother chain Kusama (Canary Network), covering multiple fields such as DeFi, NFT, gaming, metaverse, and the Internet of Things. For example, projects such as Acala, Moonbeam, and Phala Network are all important components of the Polkadot ecosystem. Together, these projects have built a rich and diverse application layer, attracting a large number of developers and users.
3. Technological innovation and influence: Polkadot's cross-chain technology and shared security model are its core innovations, solving the long-standing "island effect" problem in the blockchain field. This design concept is widely regarded as one of the directions for the development of the next generation of blockchains, and has also had a profound impact on the research and development of other public chains. For example, many new projects are also exploring similar modular and interoperability solutions.
4. Developer Community: Polkadot has a huge and active developer community that provides complete development tools and documentation. The Web3 Foundation and Parity Technologies continue to invest resources to support developers, host hackathons and seminars, further strengthening its position as a developer-friendly platform.

To sum up, whether in terms of market performance, ecological prosperity, technological innovation or community activity, Polkadot is undoubtedly the mainstream force that cannot be ignored in the current blockchain technology landscape.
