What is cryptocurrency?
Polkadot 由以太坊联合创始人 Gavin Wood 创建，是一种分片多链协议，允许异构区块链彼此通信。
Polkadot 通过被称为副链的分片链、副链和连接外部区块链的桥这四个主要组件实现了异构区块链的跨链通信。这种模块化架构使 Polkadot 比其他 Layer 1 区块链更有效地扩展，让独立的网络在彼此之间传输信息。
开发者可以使用 Polkadot 的姊妹网站 Kusama 进行试验。项目可以通过竞拍插槽赚取收益。与按顺序处理块的传统区块链网络相比，Polkadot 的副链支持块的并行执行，减少了网络拥塞。
Polkadot 的原生代币是数字货币 DOT，可以用于竞标副链插槽，以激励参与其指定的权益证明共识机制，并作为治理代币和价值交换媒介。
