This provides a lot of security but isn’t very scalable, because the entire network can only store as much data and process as many transactions as a single machine. 这提供了许多安详性，但可扩展性不佳，因为整个网络只能存储和处理惩罚与一台呆板沟通的数据和生意业务。

In this way, the network can scale, without scarifying security as there’s still more than one node storing each piece of data and processing every transaction. 通过这种方法，网络可以扩展，而不会损害安详性，因为仍然有多个节点存储每个数据块并处理惩罚每个生意业务。

The Ethereum core team has come up with a proposal, which uses sharing to divide the blockchain data among nodes and allow nodes to process different transactions in parallel. Ethereum以太坊焦点团队提出了一个方案，利用分片技能在节点之间分别区块链数据，，并答允节点平行处理惩罚差异的生意业务。

This makes the data a lot faster to store and a lot easier to query. As far as blockchains are concerned, every node has to store all the information on the blockchain locally, and process all incoming transaction. 这使得数据存储更快，查询也更容易。就区块链而言，每个节点都必需在当地域块链上存储所有信息，并处理惩罚所有传入的生意业务记录。

Instead of every node performing every transaction and storing all the data, nodes will be broken up into smaller groups, and each group will handle one part of the data in transaction processing. 不是每个节点都需要执行每个生意业务，并存储所有数据，而是将节点解析为更小的组，每个组将处理惩罚生意业务中的一部门数据。

Sharding is a type ofdatabase partitioning that breaks up very large data sets into smaller chucks, or shards and stores them in separate machine. 分片是一种数据库分区，它将很是大的数据集支解成更小的块，可能将它们分片并存储在单独的存储器中。
