Records, irrespective of their nature (whether electronic or paper-based), are vulnerable to fraud. People's hard-earned money, their personal information, identity, and health are at a higher risk than ever due to the misuse of technology in doing forgery. However, the technology can also be used as an answer to counteracting against fraudulence prevalent in affairs from every walk of life. This short paper attempts to present the blockchain technology as a solution to overcome the menace of forgery by promoting trustless computing in business transactions. The paper explains the blockchain technology and a variety of its implementation through five different use cases in the field of drug supply chain, health insurance, land record management, courier services, and immigration records. The immigration blockchain is also proposed as a solution to check pandemic like the coronavirus (COVID-19) effectively. The implementation of the Blockchain is performed using a locally built IBM’s hyper-ledger fabric-based platform, and Ethereum public platform. The results are encouraging enough to substitute existing business operations using Blockchain-based solutions.

记录，无论其性质如何（无论是电子的还是纸质的），都容易受到欺诈。由于滥用技术进行伪造，人们的血汗钱、个人信息、身份和健康面临比以往更高的风险。但是，该技术也可以用作对抗各行各业事务中普遍存在的欺诈行为的答案。这篇简短的论文试图将区块链技术作为一种解决方案，通过促进商业交易中的去信任计算来克服伪造的威胁。该论文通过药品供应链、健康保险、土地记录管理、快递服务和移民记录领域的五个不同用例解释了区块链技术及其各种实施。移民区块链也被提议作为有效检查冠状病毒（COVID-19）等流行病的解决方案。区块链的实施是使用本地构建的 IBM 基于超账本结构的平台和以太坊公共平台执行的。结果令人鼓舞，足以替代使用基于区块链的解决方案的现有业务运营。
