Abstract: In last decade crypto currencies become popular as there is no third party involvement while doing the transactions. Blockchain is the technology for using crypto-currencies. It attracts the attention of researchers and academicians , along with different features of Blockchain it is having the major issue of scalability which can be categorized into throughput , cost, capacity and networking . Improvement in Scalability affects the application of blockchain in business . Scalability affects due to some other factors like block interval time and block size which also may reduce the security . System may become vulnerable to different attacks if we blindly modify the scalability .In this paper we analyze the different ways to improve the scalability then we compare the features of blockchain with respect to different algorithms used to solve the scalability issue. Keywords : Blockchain, scalability, throughput
Keywords: Speech recognition, Text to speech, Voice mail, visually challenged people.
