Course Dashboard

-

I can explain what a blockchain indexer does and evaluate trade-offs for using one in my application. I can identify when an event handler isn't enough and choose a query-based approach instead. I can store and retrieve data using Adder. I can select the right query provider for my application. I can combine live event data with historical query data to build a more complete picture of blockchain activity.

-

I can find and fix bugs in a Go program using debugging tools. I can work with Go's type system to make different parts of a program fit together. I can build a command-line tool with multiple commands using the Cobra library. I can create a web API that handles requests and sends responses using Fiber in Go.

-

I can trace how a type defined in Aiken appears in a blueprint file and in Go code. I can build a transaction that mints or burns tokens using a native script (no smart contract required). I can build a transaction that mints or burns tokens using a validator script (smart contract). I can build a transaction that unlocks tokens held by a smart contract. I can build a transaction that attaches data to a new output on the blockchain. I can build a transaction that passes input data to a smart contract using a redeemer.

-

I can create a wallet with Bursa. I can build a simple transaction with Apollo. I can sign a transaction manually and programmatically. I can submit a transaction to a node with gOuroboros. I can set a time window that controls when a transaction is valid. I can add simple metadata to a transaction.

-

I can set up and run the gOuroboros Starter Kit to connect to a Cardano Node. I can fetch specific blocks from a remote Cardano Node. I can check how far a Cardano Node has synced with the blockchain. I can fetch information about pending transactions waiting in a Node's mempool.

-

I can set up and run the Adder Starter Kit to watch blockchain events. I can configure Adder to connect to a Cardano Node. I can use Adder to filter blockchain events by type, address, policy, or stake pool.

-

I can describe what Cardano is, how its blockchain differs from others, and what kinds of applications can be built on it. I can explain how Ouroboros reaches consensus and why that matters for building on Cardano. I can explain why Bursa was built and what problems it solves. I can explain why Apollo was built and what problems it solves. I can explain why Adder was built and what problems it solves. I can explain why Cardano Up was built and what problems it solves. I can navigate the course structure and set up my development environment for the modules ahead.
