Block chain technology is a decentralized data storage structure based on a chain of data blocks that are related to each other. Block chain saves new blocks in the ledger without trusting intermediaries through a competitive or voting mechanism. Due to the chain structure or the graph between each block with its previous blocks, it is impossible to change blocking data. Block chain architectur...
This project proposes a blockchain-based framework from the existing centralized for ride- sharing service and implements same as decentralized application based on smart contracts Polygon Blockchain. A ridesharing system helps riders to reach particular destination driven by owner of ride. Most services available in market are hosted third party which gives them authority monitor features like...
Distributed cryptographic protocols such as Bitcoin and Ethereum use a data structure known as the block chain to synchronize a global log of events between nodes in their network. Blocks, which are batches of updates to the log, reference the parent they are extending, and thus form the structure of a chain. Previous research has shown that the mechanics of the block chain and block propagatio...
