如何简单读懂“区块链”的概念

区块链技术，可以简单地理解为，交易的信息在网络中的每个区块上都存储过一遍，而且这些信息都是加密的。

Block chain technology can simply be understood to mean that the information traded is stored on each block of the network and that it is encrypted.

区块链技术的“分布式”可以理解为，交易的数据不是存在一个地点，而且在所有的计算机上都存储一次。因为数据是分布在所有的计算机上，所以叫做“分布式”。

The "distribution" of block chain technology is understood to mean that the transaction data do not exist in a single location and are stored on all computers once. Because the data are distributed on all computers, it is called "distribution."

区块链技术的“区块链”的意思是，当要记录一个数据的时候，就要创建一个新的区块来记录数据，这个区块不仅包含了当前这个数据，还包含了下一个区块的信息。所以，区块链技术是需要很多个区块链接结合起来的，就像一个网一样。

The "block chain" of block chain technology means that when a data is recorded, a new block is created to record the data, which contains not only the current data, but also information on the next block. So the block chain technology requires many blocks to be linked together, like a network.

因为一个区块不仅记录了当前的信息，还有下一个区块的信息。所以，想要改变一个区块的信息，要改动的不仅仅是一个区块的信息。因此，区块链上存储信息是很安全的。

Because a block not only records current information, but also information about the next block. So, if you want to change information about a block, you want to change it more than just information about a block. So, it's safe to store information on the block chain.

区块链是通过在所有计算机上记录交易信息，所以，就不需要考虑第三方的信任问题。

Block chains are recorded through the recording of transactional information on all computers, so there is no need to consider the confidence of third parties.

因为存储的信息需要在所有的计算机上记录过一遍，所以需要花费大量的时间和空间。

Because the stored information needs to be recorded on all computers, it takes a great deal of time and space.

随着更多的人参与到区块链中来，区块链的技术的应用成本也会随之提高。所以，因为成本的原因，区块链后期的推广会遇到一些麻烦。

As more people are involved in the block chain, the cost of applying the technology in the block chain will increase. So, for cost reasons, there will be some problems with the later extension of the block chain.
