CloudWallet provides blockchain solutions to help businesses simplify developing applications and securing data. It addresses challenges with centralized systems like single points of failure and lack of transparency. CloudWallet's blockchain network allows for secure, private, distributed data storage and transactions without trusted third parties. A case study shows how blockchain could improve security over centralized solutions by encrypting user data and avoiding single points of compromise.

- 25. 05 Case Study Centralized Trust 3rd Parties lets you store your private data in their storage. – Certificate Authority(or bank and etc) has ‘master key’ so can decrypt all your data. – A bug or security breach in C.A can expose all your data. – Suffer possible corruption of 3rd parties
- 26. 05 Case Study DropBox lets you store your files in the cloud. • For efficiency reasons, if 2 or more members have the same file , DropBox doesn’t want to store it twice. • For security reasons, it’d be nice if DropBox could encrypt your files on your computer (with a key only you know) and upload the encrypted version. • In fact, on 6/19/2011, DropBox did have a bad bug, where they screwed up the authentication: you could log into someone else’s account without knowing their password (just enter any password, and you’re in). This exposed everyone’s files to the world.
