听wood说 Will there eventually be one blockchain to rule them all? We don’t think so.

All blockchains make different tradeoffs to support specific features and use cases, and as chain specialization increases, the need to transact between them will only increase over time. Polkadot is a sharded blockchain, meaning it connects several chains together in a single network, allowing them to process transactions in parallel and exchange data between chains with security guarantees. Thanks to Polkadot’s unique heterogeneous sharding model, each chain in the network can be optimized for a specific use case rather than being forced to adapt to a one-size-fits-all model. More chains and more specialization means more possibilities for innovation. 所有的区块链都会做出不同的权衡 支持特定的特性和用例 随着连锁专业化程度的提高，需要 他们之间的交易只会增加 随着时间的推移。 Polkadot是一个分片区块链，意思是 它把几个链连接在一起 单一网络，允许他们进行处理 并行事务和交换数据 具有安全保证的链之间。 多亏了波尔卡多独特的异质 分片模型，每个链在网络中 可以针对特定的用例进行优化吗 而不是被迫去适应 放之四海而皆准的模式。 更多的连锁和更多的专业化意味着 更多的创新可能性。
