Abstract
One of the biggest innovations recently in the field of computer science is cryptocurrencies and Blockchain is at the heart of it. Cryptocurrency is one use case of blockchain and there can be many more. Blockchain is an incorruptible digital ledger of economic transactions that can be programmed to record not just financial transactions but virtually everything of value. Block chain is a shared (decentralized) database and this database is continuously reconciled. This Blockchain database is decentralized i.e. data is not stored in a single location, means it can be public and verifiable. Hacker cannot corrupt the information, as he may have to hack all the copies to manipulate an information. The intention is not only implement another use case (Digital storage vault) of Blockchain but also build from ground up a new blockchain engine based on its principles of distributed ledger and cryptographic hashing. The Digital Storage Vault system will be used to manage and store the Digital Will uploaded or typed by a user. The system will provide the authenticity of the will stored in form of cryptographic hash and the security of the Digital Will. This system will thus ensure that the user who has created this will is the only one who modifies it. No one else can update or make changes to the will. If an unauthorized modification is made then the modified digital will shall be replaced by the original will during the sync. The entire system will be developed in Java language.
