高三区块链知识考试题及答案,区块链参考答案

关于区块链这一新兴技术，近几年受到越来越多人的关注，也被越来越多的行业所采用。下面就从三个关键词来介绍区块链：

去中心化是区块链技术的核心概念，它是指没有中心控制者的点对点网络，而不是由单一实体控制和管理。网络中的每个节点都是独立的，每个节点都可以对网络进行记录，每个节点都可以参与网络的管理，每个节点都可以查看网络中的所有信息。这种去中心化的网络架构可以降低网络中出现的网络故障的风险，也可以提高网络的安全性。

共识机制是区块链技术的重要组成部分，它是指网络中的结点之间协商达成一致的机制。网络中的节点可以通过共识机制来完成交易的确认，使网络中的数据得到保护，达到可信赖的目的。一般情况下，共识机制分为工作量证明、拜占庭容错、共识算法等，它们可以帮助网络中的节点实现可靠的交易确认，从而保证网络的安全性和可信赖性。

智能合约是区块链技术的一种应用，它是一种可以自动执行的计算机程序，可以用来实现自动执行合同的功能。智能合约可以让参与者无需受到中央管理者的约束，就可以实现自动执行合同的功能，从而提高了交易的可信赖性和安全性。智能合约可以用来实现自动执行的交易，可以用来实现自动结算，还可以用来实现自动执行的财务管理等功能。

以上就是关于区块链的介绍，从去中心化、共识机制和智能合约三个关键词来看，区块链技术可以提高网络的安全性和可信赖性，并且可以用来实现自动执行合同的功能，为社会各行各业带来了很多便利。

⑴ The entire system of blockchain uses a large number of cryptographic algorithms, and the more representative one is the hash algorithm used for PoW.

The entire system of the blockchain uses a large number of cryptographic algorithms, and the more representative one is the hash algorithm used for PoW. Zheng Zheng doesn’t know how to solve the problem. For this reason, the editor will collect and organize for everyone. The entire system of blockchain uses a large number of cryptographic algorithms, and the more representative one is the hash algorithm used for PoW. If you are interested, come and take a look at the solution.
The entire system of the blockchain uses a large number of cryptographic algorithms, and the more representative one is the hash algorithm used for PoW.
A. Correct
B. Wrong
Correct answer: A
The encryption algorithm in blockchain technology plays a crucial role. In addition to hashing algorithms for PoW, there are also symmetric and asymmetric encryption algorithms for encrypted data transmission, digital signature algorithms, etc. These algorithms ensure the security, immutability and anonymity of the blockchain.
