Polkadot is a heterogeneous multi-chain protocol that enables cross-blockchain transfers of any type of data or asset, not just tokens. Founded by Ethereum co-founder Gavin Wood, Polkadot uses a relay chain architecture that connects multiple specialized blockchains called parachains into a unified network. The platform features shared security across all connected chains, on-chain governance allowing token holders to vote on protocol upgrades, and forkless runtime upgrades. Polkadot's Substrate framework allows developers to build custom blockchains optimized for specific use cases, while XCM (Cross-Consensus Messaging) enables seamless communication between parachains. The ecosystem includes over 50 active parachains spanning DeFi, identity, gaming, IoT, and more. Polkadot 2.0 introduces agile coretime allocation, making blockspace more flexible and accessible.

加密 DAO

Polkadot 通过 OpenGov 提供复杂的链上治理，DOT 持有者可以通过去中心化决策过程提出、投票和实施协议变更。

加密质押

Polkadot 使用提名权益证明，其中 DOT 持有者可以提名验证器或自己运行验证器节点来保护网络并赚取质押奖励。

开发者工具

Polkadot 提供 Substrate 框架用于构建自定义区块链，以及全面的 SDKs、文档和平行链开发的开发者资源。

L1 区块链

Polkadot 是一个第 0 层/第 1 层多链协议，通过共享中继链连接专业区块链（平行链），在整个网络中实现互操作性和共享安全。
