Code Farmer's Daily - Lesson 3 of "Ama Workshop": Creating a Keplr Wallet and Understanding Validator Voting

Ok, this time this course comes to the third lesson, the content of the third lesson is " Creating a Keplr Wallet and Understanding Validator Voting "

In this lesson, our team will lead you to understand the Keplr wallet, and switch from the operation of the Keplr wallet to the voting consensus mechanism in the blockchain ecosystem. I will briefly organize the outline as follows:

1. Understanding the Risks of Liker Land Wallets
2. Understand what you should be aware of when using a decentralized wallet like Keplr
3. Learn to open a Keplr wallet and load LikeCoin
4. Learn to vote and stake with the Keplr wallet

Okay, that's about it, let's get started!

Do you think Liker Land wallet is really safe?

First of all, what do you think about the Liker Land wallet?

It's convenient and easy to use. Basically, as long as you have a Google/Apple/Twitter/Matters account, you can easily see your writing results on your mobile phone; transfers, collections, and even pledge validators can make money quickly. operate

But in fact, although this is very friendly to newbies, it is generally a fact that " the more useful things are usually the more dangerous ", this is a constant fact

I remember my old high school teacher saying:

There are two things in the world that no one else can take away, one is what you eat, and the other is the knowledge in your head

Yes, in fact, the safest way to prevent leakage is to remember it and not disclose it to others. Therefore, everything in today's society that helps you remember or automatically fills in your account password will expose you to risks.

(Speaking like this, I love to use it myself XD)

Therefore, here, we have to mention how to obtain information on Liker Land. According to this article by @catding  Your wallet is not your wallet - Single Point of Failure and Security Issues with LikerLand Wallets

Possibly, sometimes the great god speaks too philosophically, and it is difficult for mortals to understand this (no)

Not your Keys, Not your Coins . This is the only truth in the cryptocurrency world. Generally speaking, our wallets should theoretically have a set of Keys. If you want to obtain cryptocurrency wallet information, you should theoretically have to do it yourself. Enter Key to open

However, Liker Land does not require you to use any key. In order to make it easy for users to operate, they bind the key to these third-party accounts such as Google, so that you can easily have the first life without touching such complicated things. cryptocurrencies

And what is Key? In fact, if you want to discuss it very deeply, the key looks like this

Among them, the key is divided into a public key and a private key; the public key is for the encryption server to see, and others can see it, but the private key can only be seen by yourself, and if you lose your wallet, it is basically broken.

but! !

You fucking tell everyone to watch this, can you still play? ? ? ? ?

So later, the cryptocurrency world extended a technology called "mnemonic phrase", which is a string of "passwords" consisting of 12 to 24 English words, and this string of passwords is used to replace the " key " that can open the cryptocurrency wallet.

OK, after so much talking, I still don't understand why the risk of Liker Land is, I only understand " Oh! So in short, the key has to be kept by himself, right! Then what? "

I bet you wouldn't necessarily come to that conclusion (laughs)

That's right, if you already have the concept of " the key is to be managed by yourself ", then you may be a little wary of what I will say next.

Correct, because Liker Land's private key management mechanism is the opposite of self-management - escrow

Currently, Liker Land uses this escrow mechanism to help you manage LikeCoin. Since this escrow mechanism does not conform to the "belief" of decentralization, we still recommend that everyone try not to put LikeCoin on LikerLand as much as possible from the perspective of risk control.

Therefore, after understanding the mnemonic and risk control, our team has come to this conclusion about the control of this part

Finally, we also provide the following table for you who are hesitant to open a Keplr wallet for your reference.

vote

In the world of LikeCoin, there is a well-known mechanism for "voting for validators"

What is the motion? What is the validator going to do? These sounds a lot like play mechanics, do they really make sense?

In fact, this is the case, because if cryptocurrencies are to develop, they must be governed by someone. However, if the issuer always does things stubbornly, it will lead to dissatisfaction among many holders, and even technical partners may have many situations.

Thus, in the governance of cryptocurrencies, a condition called Proposals and Voting was born. And the proposal is usually if everyone needs to jointly seek a decision on the governance of cryptocurrency (for example, to join the OSMO platform, or to upgrade LikeCoin, or to distribute bonuses or hire a big guy to join the team, etc.), it will go through the voting process. Seek everyone's consensus

And the work of voting naturally falls in the hands of each validator

In fact, the term "entrustment" has been mentioned before. The previous statement was that "a validator is like opening a bank, and you put money in to earn interest for him"

This statement is because I haven't talked about delegation and voting at that time, so I will use a way to let everyone understand. Now that everyone has some understanding of voting, we can reveal the identity of the verification people who want to "vote"!

Of course, as of now, the delegators can vote by themselves, and no longer need a validator to help vote

And, how much do you know about a motion? The following is the proposal flow table

And what are the options for voting?

Finally, learn how to vote!

implement

Open a Keplr wallet!

First please use this link -> click me

Once loaded, create a wallet

After creating it, you may find that you can't find LikeCoin?

How to do it?

Gaying on the same scene: Stealing money

In this course, I also added a course to teach you how to "steal" wallets XD

Everyone wakes up when they hear about stealing someone's wallet

In fact, it is not a very powerful hacking behavior. On the whole, it is an extension of a small activity in the article " Pseudo-Teaching Real Games | Likecoin Hot Wallet " by @JohnShao .

And we are on the scene in the workshop video, demonstrating a "stealing money" for everyone to see, and let everyone actually play once XD

Later, many people shared their experience of "stealing money", it seems that it is really human... XD

postscript

The start time of this course happened to be stuck in the busiest period when I was going to go abroad. I am very grateful to our boss @sloth's life for helping me complete this PPT. The Mic frame hasn't come with me, so I held the microphone with one hand in class that day. To be honest... It's a lot of inconvenience. QQ

But fortunately, I later received the Mic frame I sent from my home, and I could finally free my hands for the following courses (moved).

In fact, I especially like the type that walks around the streets at night. In Taiwan, because there are still many shops open at night, it feels very lively at 8 and 9 o'clock.

However, in Japan, there are usually not many cars on the road at 8 or 9 o'clock, and there are sidewalks in Japan, so you don't have to be afraid of being hit by a car while walking on the road. I personally like it quite a bit.

Later, I just wandered casually, and then I wandered to Kobe Port XD

Then I was blinded by the couple over there... What the hell am I doing? QQ

It's just a little recent situation to share. Actually, I don't like to share too much. It feels like showing off. I don't like it.

Anyway, next class on 4/23 at 8:30pm! Looking forward to seeing you online!
