区块链技术及其在加密货币外的应用

区块链技术(Blockchain,BC)是支持比特币这类加密货币的重要底层技术,其对于确保其他领域如物联网(IoT)系统的安全性及隐私性也可起到重大的作用。目前,相关研究人员正在对区块链技术在加密货币以外的应用场景进行深入研究。工作量证明(Proof of Work,PoW)使用了哈希算法,通过记录并管理发生交易的电子账簿来保证数据安全,防止数据被篡改。此外,区块链技术采用了可变公钥(Public Key,PK)来记录用户的身份,提供多一层的隐私保护。区块链技术不仅在加密货币领域应用广泛,在其他领域应用也得到了实现,例如:分布式存储系统、位置证明、医疗保健、投票系统等等。本文在研究了相关区块链的文章及应用场景的基础上,将评估区块链技术在其应用场景增强数据安全性实现情况,并将总结区块链技术及其在加密货币之外的应用并得出适当的结论。

Blockchain(BC)is an important underlying technology supporting cryptocurrency such as Bitcoin.It can also play a significant role in ensuring the security and privacy of other fields such as the Internet of Things(IoT)system.At present,relevant researchers are conducting in-depth studies on the application scenarios of blockchain technology beyond cryptocurrency.Proof of Work(PoW)USES a hash algorithm to secure data and prevent data from being tampered with by recording and managing the electronic ledger in which transactions take place.In addition,blockchain technology USES Public Key(PK)to record the identity of users,providing an additional layer of privacy protection.Blockchain technology is widely used not only in cryptocurrency,but also in other areas such as distributed storage systems,location proof,healthcare,voting systems and so on.Based on the study of relevant blockchain articles and application scenarios,this paper will evaluate the implementation of blockchain technology in its application scenarios to enhance data security,and summarize the blockchain technology and its applications beyond cryptocurrency and draw appropriate conclusions.
