Early blockchains were like walled gardens closed off to other networks. But as the number of chains for specific use cases continues to rise, so does the need for cross-chain communication and interoperability. Polkadot’s cross-chain composability and message passing allows shards to communicate, exchange value, and share functionality, opening the door to a new wave of innovation. Thanks to Polkadot’s ability to bridge blockchains, Polkadot shards will also be able to interact with popular decentralizedfinance protocols and cryptoassets on external networks like Ethereum.

早期的区块链就像墙壁一样 花园与其他网络隔离。 而是作为具体的链数 用例继续增加，所以 需要跨链沟通和 互操作性。 圆点花纹的过渡链可组合性 消息传递允许碎片 沟通，交换价值，分享 功能性，开启了一扇崭新的大门 创新的浪潮。 多亏了波尔卡多的桥接能力 区块链、圆点碎片也将是 能够与流行的去中心化金融协议和加密资产进行交互 像以太坊这样的外部网络。

Polkadot unites a network of heterogeneous blockchain shards called parachains. These chains connect to and are secured by the Polkadot Relay Chain. They can also connect with external networks via bridges.

波尔卡多联合了一个网络 异构区块链碎片 叫parachains。这些链 连接到并受到保护 波尔卡多中继链。他们 还能与外部连接吗 网络通过桥梁。
