ANN based block chain security threat mechanism

Abstract

Blockchain was first introduced to the world in a form of crypto currency. Since then it’s grabbing popularity day by day and has already started changing lifestyle and business process in some areas. The Blockchain is a data structure, and consists of time-stamped list of blocks, used to create a digitally secured, transactional ledger that, facilitates the process of recording transactions and tracking assets in a distributed business network instead of resting with a single provider. It brings a paradigm shift from the conventional way of storing transactional data, exchanging value, assets decentralizing and sharing data across a large network of untrusted participants without intervention of any centralized trusted agency, but still building a trusted system without compromising data integrity, security and reliability. This paper is based on survey of different consensus mechanisms already available so far and an introduce our own approach to tack one of the security threats by introducing a Neural Network to the consensus mechanism of Blockchain.
