πŸ“šMission 3 - NEO

Exploring block details

We are evolving. In the last two missions, we set up our NeoLine wallet and understood how to read the information such as token balance and transaction highlevel details. NeoLine wallet is just a way to visualize a part of what is on the blockchain. NeoLine is more focused on managing your balance on each token.

There are other ways to view your wallet and the transactions that took place on the blockchain, which are scan websites. And in this mission we will learn how to use them.

Attention, do not confuse scan with scam! Scan with N means to examine, probe, explore. Scam with M stands for fraud, swindle, a fraudulent scheme. We’re not messing with any scams here, okay!? πŸ˜‡

Just to recap, when confirming mission 1, you received 1 point something MELK and in mission 2, you received 5 MELK. There were two transactions carried out to reward your good performance.

So let's learn how to view these transactions.

Each blockchain has one or more websites that can be used to view transactions, but each has an "official" website that most people use.

In NEO's case you can use NeoTube as suggested in your wallet, which can be accessed at https://neotube.io/

There’s also https://dora.coz.io/ and https://explorer.onegate.space/homepage. Feel free to explore them later just out of curiosity. The difference between them is the way they show the information, the easiness to save addresses and the monitoring with notifications by e-mail for certain transactions.

As we are using the NeoLine Wallet, we are going to use NeoTube for our exercise.

1. Access the NeoTube website

Open your browser and go to https://neotube.io/

You will see a page as shown in the image below.

In the top right corner of the screen, you'll notice the label "MAINNET." This refers to the primary network of NEO. However, since our focus is on the TESTNET, we need to switch networks. To do this, simply use the dropdown menu to select "TESTNET." Once changed, the overall view remains consistent; the only difference will be the specific network indicator, showing which network's information you're viewing. It's important to always ensure you're on the TESTNET view, otherwise, you won't be able to see any relevant transactions. For direct access to the TESTNET, you can also use the following link: https://testnet.neotube.io/.

2. Copy and paste your address into the search field.

Do you remember mission 1 where we copied our public address (similar to a Bank key, bank account number) from NeoLine? For this mission, we'll have to copy it again.

Open the NeoLine extension at the top right of your browser. Then copy your public address as shown in the image:

After copying the address, paste it into the NeoTube search field and click the search icon.

The result should be similar to this. Let's find our transactions!

3. Finding the transactions

Let's confirm that we are on the same screen. It should look like this, under assets you should see NEO, GAS and MELK tokens with their respective balances. Don't worry if your balance is not the same as mine, the important is to have the 3 different assets listed.

Now scroll down a bit and click on the first transaction based on time, under the section TRANSACTIONS.

This is what you should see now, a tab called TRANSACTION INFORMATION.

Here you can see the details related to the transaction we sent you, including the sender, the Network Fee, the System Fee, the wallet address from the sender and the receiver with the amount in MELK just below. All information coming directly from NEO blockchain.

4. Understanding transactions

Simply put, when a transaction is requested and authenticated, it is placed in a block, which will represent the transactions that are within it. It is important to understand that a block contains multiple transactions. NEO currently has a maximum transaction size of 100 KiB and a maximum of 500 transactions per block. This block is then sent to a queue called pool. When you leave the queue, the validating nodes of the network (which will validate the transaction and place it on the current blockchain) validate the transaction and receive the reward for having validated (an example is Bitcoin miners, which are actually validators). Afterwards, the block is added to the existing blockchain, and this update is distributed across the entire network. After finishing this process, the transaction is complete.

Here is a summary of the process:

5. Send the first transaction Txn Hash on Discord to receive the reward for this mission

Congratulations on getting here! Head over to the Discord server where you are following the knowledge trail and send a message with the transaction hash that has the value of 1. something MELK token, which we saw on the NeoTube website. In my case, I would send this long string of numbers and letters you see below, to copy simply click on the + icon in blue.

From there, just copy from the button marked above and send it on Discord!

If you have any questions, feel free to message us on our Discord support channel.

In this mission we had 2 lessons: We learned how transactions work and we learned to visualize our transactions using NEO Blockchain Scan site.
