Hello everyone Obeisance.
Hope you all are excellent and safe. I am Sanaton Chandra Roy from Bangladesh. Today I am executing my achievement task 2. I have read and comprehended the fundamental security of steem. And I understand the purposes, regulations, use cases, and qualities of each security keys.

After the steemit registration, I got all the security keys. Here I am talking about some of the concerns in achievement task 2 . below I am giving a thorough explanation of the questions

SECURITY IN BLOCKCHAIN
" Blockchain technology creates a structure with innate security traits. it is based on the tenet of cryptography, decentralization, and agreement, which guarantee confidence in the security.

Security means protecting ownership. It helps the users to maintain their privacy and it protects their data, information, documents, etc. from others which means, that only the user can access his data, thereby keeping the data secure.

RETRIEVE
I got my keys after registration on steemit. i got the keys in the form of a long alphanumeric format. So it is very protected and secure. Also, I got the keys in a pdf file. The digital file is saved in my google drive and can only be accessed by me

FUNCTIONS AND KEYS
There are mainly 4 types of keys.
Owner key
Active Key
Posting key
Memo key

ACTIVE KEY
Active key is a type of key that is used for financial transactions such as fund transfer, power up/down transactions, converting SBD, editing profiles, and fixing orders in the market. It is also used for wallet transactions.

OWNER KEY
It is separated from our master password. It can modify any account key including our owner key. This is a strong key.

MEMO KEY
It is used to encrypt or decrypt the inscriptions when sending funds.

Posting key
You can upvote or downvote other posts using the posting key. For uploading articles to Steemit and commenting on other posts. Remember that we should always sign in to Steemit with our private key, because this key gives you access to everything.

KEEP MASTER
I already did it. Because I already created my account. I saved my master password in my google drive, so no one can access my master password. I know the consequences if I lose my master password. So i ensure that i do not lose my master password anyway.

TRANSFER
YES, I know how to transfer steemit to another steemit user account. Here I am submitting a tutorial to transfer Steam Token to another Steam user account.

Step 1: First log in to my Steemit account using my username and password. After that I will find your profile, in that profile, I will see the wallet button, click on the button.

After open the steemit wallet page then i can see the wallet information

Step 2: I will find a Power Down button with options like Transfer, Transfer to Savings, Power Up, Trade, and Market.

Step 3: then I Click on the transfer button. After that, I get a page that includes From, to Accounts and I will see the amount box.

After Fill up the items of the receiver address and I will click the NEXT button

Step 4: After that I will get a new sign in page. There i want to put our Active key or owner key or Master password to perform the action.

After putting the key enter to sign in and then the transaction will be completed.

POWER UP

First I have to go the power option. Then using the power up option I can increase my power value in steemit

Step 1: To power up, first I need to go to the wallet which is done earlier.

In the drop-down menu list, I can see the power-up button. Click on the power-up button.

Step 2: After that I will get a new page like this

Fill the amount box and click in the power up button.

After that I will get a confirm transfer to vesting. click ok to confirm

Step 3 : After that I get a new page for entering the active or owner key or master password to complete the action.

So, this was my take on Steemit basic security. As much information as I could. I think this will satisfy you. Ending my achievement 2 wishing everyone a great future on Steemit.
