Unlike traditional centralized systems, where a single entity controls the ledger, blockchain is maintained by a network of nodes. This means that there is no single point of failure, and the system is more resilient to attacks”,即区块链去中心化的优点是没有单点故障,系统更能抵御攻击。
What is blockchain technology? A. A centralized ledger technology. B. A decentralized ledger technology. C. A traditional financial process. D. A new type of bank. 相关知识点: 试题来源: 解析 B。解析:文章中明确提到“Blockchain is a decentralized ledger technology”,即区块链是一种去中心化的...
However, block chain is poorly understood, which is one of the impediments of its adoption. Close to 80% of people around the globe do not understand what it is. This is the first series of blockchain tutorials which covers all the aspects of this technology. We will understand blockchain ...
Blockchain is still plagued by a number of challenges, with some of the main issues being transaction bottlenecks, scalability limits and high levels of energy consumption. Can blockchain transactions be reversed? No, blockchain transactions can’t be altered after being initiated. This is due to...
new blockchain: the first block would be there, shiny and new, but lonely. Then, the second block would come along and say, “the block before me is the first block.” The next block would say “the block before me is the second block,” and so on, creating a chain (of blocks)...
解析 C。解析:“Overall, blockchain technology has the potential to transform many industries and bring about significant changes in the way we do business and interact with each other.”,总的来说,区块链技术有潜力改变许多行业,并在我们做生意和相互交流的方式上带来重大变化。
B。中文解析:区块链技术的安全性主要在于其加密特性。文章中提到“The security of blockchain technology lies in its cryptographic nature.”,即区块链技术的安全性在于其加密性质。A 选项集中化性质错误,区块链是去中心化的;C 选项高处理速度不是安全性的主要原因;D 选项大账本尺寸也不是安全性的主要原因。反馈...
Each block is hashed and linked to a previous record, and the reference of the previous block is stored in the current block. What exactly is blockchain? Let’s get a little technical and understand what exactly blockchain is. Here is my simple definition. ...
(The caveat to note here is that some blockchains now make it possible to distribute compute resources in addition to data. For more on that, see below.) What Makes Blockchain Special? If blockchain is just another type of database, why are people so excited about it?
To change that piece of data, they would have to generate a new nonce, which they couldn't do because the old nonce is already recorded in the blockchain, complete with a timestamp. As long as people can see the blockchain and more than one person contributes to it, any piece of dat...
