However, for read-only function calls, transactions are **not** required. Instead, these calls can be done using the [Stacks Blockchain API](/references/stacks-blockchain-api).

In this tutorial you will extend a to-do app to share individual lists publicly using the Stacks 2.0 blockchain. The to-do app was built in the [to-do app tutorial](/authentication/building-todo-app). The registry of shared to-do lists is implemented by a Clarity smart contract named [`todo-registry`](https://github.com/friedger/blockstack-todos/blob/tut/public-registry/contracts/todo-registry.clar). Data from this contract will be shown in the to-do app. The final app will look like this:
