关于以太坊区块链中的数据检索
[英]About the retrieval of data in ethereum blockchain
问题描述
Every data in the ethereum blockchain is hashed. 
以太坊区块链中的每个数据都经过哈希处理。 That is in the form merkel tree. 那是默克尔树的形式。
so how the retrieval data is possible as once the data is hashed it cannot be 因此如何检索数据成为可能，因为一旦对数据进行哈希处理就不可能
reversed? 颠倒了吗？

Not everything is hashed in a Blockchain. 并不是所有的东西都被散列在区块链中。 Blockchain is a data structure where transactions are stored in blocks chained by cryptographic hash functions. 区块链是一种数据结构，其中事务存储在由加密哈希函数链接的块中。 Bitcoin uses Merkle Tree to store transactions in a distributed manner. 比特币使用Merkle树以分布式方式存储交易。 Ethereum is a little bit for extensive storage architecture with ability to store the global state of the blockchain along with a few other properties of the transactions. 以太坊对于广泛的存储体系结构有点用，能够存储区块链的全局状态以及交易的其他一些属性。 Please find the attached image to understand the Ethereum Block architecture. 请找到所附图片以了解以太坊区块架构。 Ethereum stores transactions and state in Merkle Patricia Tree Structure. 以太坊将交易和状态存储在Merkle Patricia树结构中。
