Decentralized Public / Private Ledger Technology and It‟s Applications

Abstract

Block Chain (BC), the technology behind the Bitcoin crypto-currency system. Blockchain helps Build Trusted, Powerful and Transparent Process with the potential to disrupt Intermediaries, Third parties & Expensive processes. Proof-of-Work (PoW), Proof of Stake (PoS), Proof of Authority (PoA), consensus algorithm plays a vital role in ensuring BC security by maintaining a digital ledger of transactions, which is considered to be incorruptible. Firstly, we explore top crypto currencies after that we will explore blockchain and mining concept. In further we will be exploring Ethereum blockchain solidity programming more and make DAPPs on Ethereum blockchain network.
