Implication of Smart Contracts to Mitigate the Security Risk in Healthcare System

"A distributed database that maintains an ever-expanding list of ordered records, called blocks," is how a blockchain is defined.These parts are connected by the use of cryptography. A timestamp contain by each, the preceding block of a cryptographic hash , and with a transaction information. Also we can say that distributed, public, decentralized digital ledger that keeps track of transactions across several computers is called a blockchain. Its goal is to stop record tampering without interfering with network consensus or all subsequent blocks. Because blockchain and smart contracts are developed using non-standard software life cycles, there may be security flaws and difficulties in getting users to adopt the technology. For instance, distributed applications may not receive regular updates or may have bugs that can only be fixed by releasing a new version. A detailed review of smart contracts was covered in this publication. In terms of security, privacy, communication channel, etc., it further differentiated and contrasted the security of smart contracts with that of traditional security. This study also discusses other smart contract systems, including Stellar, Monax, Ethereum, Bitcoin, and Lisk. For smart contracts certain suggested methods are applied in various contexts to address security risks. Furthermore, also smart contract classification of the security application was put out in an effort to address some of the shortcomings. Additionally, the paper offers a thorough security scenario for smart contracts using several methods. Finally, the dangers and weaknesses of the smart contracts that might lead to an attack are listed. Here we can find and focuses on security risks and weaknesses specific to smart contracts.
