We have used applications like “Google Keep” or “Evernote” for taking down notes and make to-do lists. In my observation, this simple application has 3 use cases when we deploy its decentralized version on a blockchain platform. I will now explain the application design and its 3 use cases. These uses of the to-do list application are more secured, private, and tamper proof. Application Design: Like any to-do list application, we have user accounts for users to create notes in it. The application needs to be written using solidity or by any other contract oriented Turing complete language. Once the application is developed, it needs to be deployed on a blockchain. Let me summarize the parameters: User Account. List of notes written by a user. Address of the user. This is the public address of the user who writes the notes. On a blockchain, we will refer the user by this parameter. Timestamp, which is the time at which we are deploying a contract. This is very essential for a blockchain ecosystem. Let us now move on to the three use cases of this application. Use Case 1: Decentralized Twitter To-do list application can be the foundation of a micro-blogging platform like Twitter. To help you understand this let me derive an analogous relationship between our to-do list application and this platform: in the to-do list would be a on this platform. A user account user profile would be the by a User. List of notes Tweets will be the address used by the user to access their accounts. The address is the when a tweet is tweeted by the user. The timestamp time By this we can have a decentralized micro-blogging platform like Twitter. Use Case 2: Billing System A decentralized billing system can be implemented as follows: in the to-do list would be a account created for each customer. A user account separate would be the pertaining to a particular customer. List of notes bills can be used by the customer to view their previous purchases. The address is the when a bill is generated for the customer. A timestamp time Advantage: Since the bills are on a blockchain it will facilitate tamper-proof audit trails for the administration. Use Case 3: Process Management System Every company saves their processes on a document. Now the problem with this approach is that sometimes the processes might be lost or hacked or accidentally deleted. Hence, there is a need for a decentralized process management system. It can be implemented as follows: in the to-do list would be . A user account a separate process would be the or of each step in a process. List of notes procedures instructions can be used to read/write a specific process. For security reasons, only trusted persons must have access to the data. An address is the when a process is modified. A timestamp time Once this system is on a private blockchain, it can’t be deleted or hacked. These are the three use cases of a decentralized to-do list application. The following words were my motivation to study this domain: “Eventhough the chance for Blockchain or Cryptocurrency to succeed is much less than a 100%, Even if it is 10%. A 10% chance of making something that unleashes a massive paradigm shift on the entire world is still something that is totally worth dedicating your whole life to.” ~ Vitalik Buterin (co-founder of Ethereum) Thank you for reading my article.
