Hello, dear friends.Hope everyone is safe and well. Today I will present my task 2. I am working on my second achievement in the basic safety of Steemit. So, I am very happy.
After registering on steemit, I got all the security keys. Here I am talking about some of the concerns of task 2. Below I explain the question

Security in Block Chain:
Block Chain cryptography is based on decentralization and contract principles, guaranteeing safety. It creates a framework with technology-built-on security features. Safety means freedom from danger or threat. Steemit reserves ownership of the language. It protects our data, documents, information, etc., from others. As a result, the data is protected, as only the user can access his data. All information is properly secured and safe to keep private.
Restore:
I got it long alphanumeric format key. So it is very secure. Also, I got the key in a pdf file. The digital file is stored on my google drive and can only be accessed by me. So I got my key only after doing steemit registration.

Functions and Keys:
Keys are mainly of 4 types
1.Owner key
2.Active key
3.Posting key
4.Memo key

Posting key:
The posting key is used for uploading registration and other and comments on steemit. Posts are upvoted and downvoted with the posting key. But we will always sign in to steemit with the private key because it gives access to everything.

Owner key:
This is a powerful key. It separates us from our master password. It can change any account key, including our owner key.
Active key:
The active key wallet is used for transactions. It used for financial transactions like found transfer,profile editing and market order placement.
Memo key:
It is encrypted or decrypted when sending funds.
Keep master:
I save my master password in my google drive. So that no one access my master password. I know the consequences of losing the master password. So I make sure I never lose my master password.

Transfer:
I know how to transfer from one steemit to another steemit user account. Here I submit to transfer steemit token.
Step-1:I need to log in to my steemit account using my username and password to find your account. Click on the wallet button on that profile. After that, I see the wallet information.

Step-2:I will get a transfer, transfer to saving, transfer to power up, trade and market.
Step-3:Now,click on transfer button.I will get a page that will contain the from,to account and amount box.

Fill up the items of the receiver address and click the next button.
Step-4:Then I get the new sign-in page. There we want to put our Active key, or Owner key or Master password to act.
After putting the key….enter to sign in. Then the transaction will be completed
Power Up:
First, I can increase my power value in steemit by going to the power option and using the power-up option. To power up, first, go to your wallet.

In the drop-down menu list, we can see the power-up button. Click on the power-up button. Then we get a new page like this. Fill in the amount box and click on the power-up button. After we get a confirmed transfer to vesting, click ok to confirm. After that, we get a new page for entering the active or owner key of the master password to complete the action.
As for as, the information I got was the basic security of the steemit. I hope this satisfies you. Ending here today.
