区块链最直白的解释

区块链是一种技术，这种技术能够保证链上数据不可篡改、不可伪造。

The block chain is a technology that ensures that the data on the chain are not tampered with and cannot be falsified.

区块链具有五个重要技术特性：去中心化、信息不可篡改、公开透明、集体维护和可靠的数据库。

The block chain has five important technical features: decentralization, non-diversion of information, transparency, collective maintenance and reliable databases.

区块链具体解释：

block chain specific explanation:

1、区块链定义具体阐释

1. Specific elaboration of blocks chain definitions

狭义上来看，区块链是一种按照时间顺序来将数据区块以顺序相连的方式组合成的一种链式数据结构，并以密码学方式保证的不可篡改和不可伪造的分布式账本。

In a narrow sense, the block chain is a chained data structure that sequences the data blocks sequentially together and ensures in cryptographically non-falseable and non-falseable distribution books.

广义上来看，区块链是一种分布式基础架构与计算方式，它是用于保证数据传输和访问的安全技术。

Broadly speaking, the block chain is a distributed infrastructure and calculation method used to secure data transmission and access.

综上，概括来讲，区块链相当于一个去中介化的数据库，由一串数据块组成。它的每一个数据块当中都包含了一次比特币网络交易的信息，而这些都是用于验证其信息的有效性和生成下一个区块的。

In summary, the block chain is equivalent to a de-intermediated database consisting of a series of data blocks. Each of its data blocks contains information on a Bitcoin network transaction that is used to verify the validity of its information and to generate the next block.

2、区块链的基础架构

2. Foundation structure of the block chain

区块链由数据层、网络层、共识层、激励层、合约层和应用层六个基础架构组成。

The block chain consists of six basic structures: the data layer, the network layer, the consensus layer, the incentive layer, the contract layer and the application layer.

3、区块链的用途

3. Use of the block chain

区块链主要是用于解决交易的信任和安全问题。

The block chain is primarily used to address the issues of trust and security of transactions.

4、区块链不同领域的应用

4. Applications in different areas of the block chain

从科技层面来看，区块链涉及数学、密码学、互联网和计算机编程等很多科学技术问题；从应用视角来看，区块链是一个分布式的共享账本和数据库，具有去中心化、不可篡改、全程留痕、可以追溯、集体维护、公开透明特点。

At the scientific and technical levels, the block chain involves many scientific and technical issues, such as mathematics, cryptology, the Internet and computer programming; from an application point of view, the block chain is a distributed and shared account book and database with decentralized, non-manufactured, full-range marks, traceability, collective maintenance, transparency.

5、区块链需要注意的问题

5. Issues that require attention in the block chain

作为核心技术自主创新的重要突破口，区块链的安全风险问题是一大短板，频频发生的安全事件为业界敲响警钟。拥抱区块链，需要加快探索建立适应区块链技术机制的安全保障体系。

As an important entry point for core technological autonomy innovation, the issue of security risks in block chains is a short one, with frequent security incidents sounding alarms for the industry. Embracing block chains requires an accelerated search for a safety and security system that would accommodate the technical mechanisms of block chains.
