Blockchain- Secure Decentralized Technology

Abstract

Blockchain now becomes the most secure transaction management process. Starting with the
introduction paper describe functioning and types of blockchain. The detailed description of smart
contracts and to write a code in the smart contract the main language is also discussed. It is basically
the contract between the devices and the language used to build this contract is also discussed. A
comparison between the previous tradition and the latest smart contract is also focused. Paper
describes the domains where we implement blockchain for security purposes as blockchain follows
the concept of decentralization. Various platforms are discussed and the comparison between them.
Finally,the paper discusses the challenges in the blockchain. At last, we conclude that now blockchain
is covering many domains and blockchain is important where the transaction between the things
happen to make it more secure.
