INTRODUCTION

my line.png
Learning about blockchains is one very important aspect of cryptocurrency knowledge. It's also very important for a steemit user who is interested in learning about the platform to know about the steem blockchain. This homework task covers some vital aspects of the steem blockchain, including

  • Steem inflation rate
  • Steem recovery account
  • Encrypted message and use of memo key.

This homework task will follow a Q&A approach in attempting the tasks set for it, for easy understanding. It will also include some overviews where necessary.

STEEM INFLATION RATE

my line.png
Steem is a social blockchain that employs the DPoS (Delegated Proof of Stake) consensus mechanism as its governance protocol. With this protocol, it rewards a definite number of actors whose activities are similar to those of miners on PoW (Proof of Work). Steem has a reward pool from which it rewards these actors who are called witnesses.

The blockchain also has other actors who also contribute to the progress of the blockchain and are also rewarded. They include

  • Content Creators
  • Curators
  • Steem DAO
  • Vested Token Holders

Together with the witnesses, steem rewards these actors with tokens gotten from the inflation of the virtual supply of the STEEM token. Steem employs an inflationary model to create a fixed number of tokens as each block is completed, according to the inflation rate.

Following the calculations done in this coursework by the professor, assuming the current STEEM/SBD ratio continues, the table below, given by the professor, hints at the quantity of virtual supply and new steem tokens over the next 16yrs.

Q.1a

As most of the STEEM tokens will be minted in the next 10 years or so(on account of inflation), how important it is for you to build your SP in the next 10 years and build significant influence power in the form of SP?


From the table above, notice that between Mar 2031 and Mar 2021, a total of 293,206,427.3 STEEM ( ie. 685,011,397.3 - 391,804,970.0) will be created.

Here is a brief rundown of how the inflation in STEEM is allocated -

  • Witnesses - 10%
  • Steem DAO - 10%
  • Vested Token Holders (SP Holders) - 15%
  • Content Creators & Curators - 65%

So, over the next 10yrs, assuming the STEEM/SBD ratio remains constant, SP holders will be accruing 15% of 293,206,427.3 STEEM, which is about 43,980,964.095 STEEM. This will be distributed in proportion to the amount of SP each holder has.

Thus, we see that it is important for any actor on the steem blockchain to build their SP to a significant amount, so as to get a bigger/significant portion of the 43,980,964.095 STEEM that will be distributed to SP holders in proportion, over the next 10yrs.

Also, of the 293,206,427.3 STEEM which will be created over the next 10yrs (of course assuming constant STEEM/SBD ratio), 65% will go to content creators and curators. Having a significant SP and employing it in curation work will earn any actor a good portion of this 65%.

Q.1b

How difficult will it be to earn STEEM rewards after 2031?


Still from the table above, between Mar 2030 and Mar 2031, we see an increase of over 25 million STEEM, between Mar 2029 and Mar 2030, the increase was more, likewise between Mar 2028 and Mar 2029.

However, between Mar 2031 and Mar 2032, we see a lesser increase of about 22.8 million STEEM and the increase lessens as the years go by. So, after 2031, it becomes more difficult to earn STEEM.

For instance, between Mar 2036 and Mar 2037, there's only an increase of about 9 million STEEM. This increase will be shared among all the actors on the steem blockchain. The witnesses, for example, get 10%, which is approx. 900,000 STEEM.

Compare this to between Mar 2026 and Mar 2027 when there'll be an increase of over 30 million STEEM. Then, the witnesses, for the same activity gets 10%, which is about 3 million STEEM.

We can thus see that between 2026 and 2027, the witnesses earn about 330% of what they will earn between 2036 and 2037. Considering that the trend of reducing increases continues after 2031, it is, therefore, apparent that earn STEEM beyond 2031 will be more difficult than earning STEEM before.

Q.1c

From 2021 to 2031 how many STEEM tokens are going to be minted(approx)?


Between Mar 2031 and Mar 2021, the total number of STEEM tokens that will be created will be approximately -


685,011,397.3 - 391,804,970.0
= 293,206,427.3 STEEM

Q.1d

In which year the inflation and Block reward is likely to saturate(tentatively)?


The inflation rate is programmed to saturate at 0.95%. At this point also, the block reward will remain the same as the inflation rate becomes constant.

From the table above, given by the professor in the course content, the inflation rate deflates to 0.95% in Apr 2037, at this time also, the block reward is 0.708.

So, the inflation rate, as well as the block reward, saturates at 0.95% and 0.708 respectively, in the year 2037.

STEEM RECOVERY ACCOUNT

my line.png

Q.1a

Who is your recovery account in Steem, how do you check it(Hint- Steemscan), include screenshot(s)?


My steem account was created via signing up on the steemit platform. Below are the following steps for checking my recovery account.

Using my pc, I open the following link - steemscan.com

recovery-account-1.png

Next, I click on the search bar and enter my account name.

recovery-account-2.png

When this is done, I hit enter and my account details come up.

recovery-account-3.png

In the profile section, the recovery account is stated there, and it is steemit Inc.

Q.2b

In the case of any unforeseen event like hacking what information do you provide to the recovery account(or the trusted account) to initiate the recovery process?


If my account is hacked, I'll need to provide my previous keys/password to my recovery account for them to initiate the recovery process. I must do this within 30 days from the day of the incident, else, my account will be unrecoverable.

ENCRYPTED MESSAGE AND USE OF MEMO KEY

my line.png

Q.3a

How do you send an encrypted message(private message) to another peer in Steem Blockchain(include screenshot/process)?


Sending an encrypted message via memo is a possibility with minimal difficulty. Below, I'll show how I sent an encrypted message to another steemit user @jollybake.

First, I go to my steemit wallet by clicking on my profile picture at the top right corner of my pc screen and selecting wallet from the dropdown.


encrypted-message-1.png

I would like to send the memo with STEEM rather than SBD, so I go beside my STEEM balance and click the dropdown. From the options, I select transfer.

encrypted-message-2.png

The transfer dialogue box then pops up and I input the details. Notice that I start the memo with a '#'

encrypted-message-3.png

To encrypt a memo on steemit, begin it with '#'.

After inputting the details, I click on next and a confirmation dialogue box pops up

encrypted-message-4.png

I click on 'OK' and then another dialogue box pops up. In this one, I have to input my master key to send this encrypted message.

I click on sign in and that does it, the transaction is sent.

After a while, the transaction reflects in my wallet's transaction history. Since it's my account, I can see the encrypted message.

encrypted-message-10.png

However, when I sign out or open a private widow on my browser since I'm no longer logged into my account, I can't see the message. It's blank.

encrypted-message-9.png

Q.3b

Which key is required to send a private message and which key is required to decrypt it? (Example/Screenshot)?


To send a private message on steemit, you'll need a master key. To decrypt it, you'll need your memo key.

Q.3c

Either send an encrypted memo-tag to exchange and send a private message to another user?


Having sent a private message to another steemit user in a previous example, I'll now send an encrypted memo tag to an exchange.

Again, I go to my wallet and select transfer from my STEEM balance dropdown. I input my details and encrypt my memo by beginning it with '#'.

encrypted-message-11.png

I click on next and another dialogue box pops up. Then I confirm the transaction by clicking on 'OK'

encrypted-message-12.png

After confirming the transaction, I have to input my master key to finalize this encrypted memo transaction.

encrypted-message-5.png

Once I sign in, the transaction is completed.

As usual, from my account, the encrypted message can be seen

encrypted-message-13.png

Other than my account, the description is blank.

CONCLUSION

my line.png
The steem blockchain is a social blockchain that employs an inflationary model to create new tokens which are used to incentivize the various actors in the ecosystem. Holders of SP are very fortunate as they get to have 15% of the increase in the token.

On steem blockchain, stolen passwords can be recovered as long as it is within 30 days. This is because there is a recovery agent for each steem account. This agent requires previous keys and passwords for them to recover the account. They are called recovery account.

Lastly, sending an encrypted message on steemit is a simple action that only demands beginning the memo with a '#' and using your master key to sign in. Decrypting an encrypted message requires a memo key.

Thanks for reading.

Thank you for attending the lecture in Steemit-Crypto-Academy & doing the homework task-7.

Between Mar 2031 and Mar 2021, the total number of STEEM tokens that will be created will be approximately -

685,011,397.3 - 391,804,970.0
= 293,206,427.3 STEEM

That's correct.

The point to note here is that as we go down the line, the inflation rate decreases, so as the Block reward. As a result the total virtual supply is on the rise.

Even though all the virtual supply will not be in the form of SP, the total STEEM in the form of SP will also increase. This implies-- more people will partake in curation. The reward pool size is shrinking, more people will curate down the line. The upvote value will significantly drop on account of the combined effect of these two.

What would be the implication of the reduction in inflation rate and subsequent Block rewards?

Please refer to this table. I have made this calculation on the basis of reducing inflation rate(0.01% every 250,000 blocks or in other words, 0.01% reduction at every 8.68 days). I have extracted the YoY figure for simplification.

block_reward.png

We have already established that 293.2 Million will be the new supply of STEEM tokens on account of inflation from 2021 to 2031.

The average rate of new STEEM being minted per year in the first 10 years= 29.3 Million per year

March- 2036- 774.02 Millions

The average rate per year(from 2031-2036)= 17.8 Million.

The average rate from 2037 is further going to reduce to 8.64 Million

Implication:-

  • The current reward pool size is 29.3 Million per year with a total virtual supply of 391 Million.

  • 2021- SP to exercise is less(as the virtual supply is only 391 Million), and the reward pool is more- 29.3 Million per year

  • 2031- SP to exercise will be more (because the virtual supply will be more- 685 Million), and the reward pool will be less- 17.8 Million

Let's say the upvote value now is X, [Reward Pool per year= 29.3 Million, Virtual Supply=391 Million)

In 2032, the size of the Reward Pool will be 17.8 Million and the virtual supply will be 685 Million.

So the Upvote value will be X (17.8/29.3)= 0.6 X. So on account of inflation rate only it will be reduced by 40%, if we further consider the virtual supply it will be even lower than this value. Because with a virtual supply of 685 Million, the SP in effect will be more than what it is now(with a supply of 391 Million).

It is further going to reduce from 2037 onwards.

Put simply, those who build their SP over the next 10 years will rule this Blockchain. They are the potential whales, orcas, they can influence the governance, they can earn better privilege on the premise of influence power.

In the profile section, the recovery account is stated there, and it is steemit Inc.

Click on Steemit Inc, you will find that the recovery account is @steem. Steemit Inc is the owner of that account.

To send a private message on steemit, you'll need a master key. To decrypt it, you'll need your memo key.

You can decrypt it using Master Password/Memo Key.

Ideally, it should be the Memo Key to encrypt or decrypt the message. But at the moment it is not fully implemented yet. So for the time being, you can send an encrypted message using the Master Password and decrypt it using Memo Key/Master Password.

However, I would suggest not to send an encrypted message for fun. If it is really a requirement for you then only you should carry out this operation. The point is that you should avoid using a highly sensitive key like Master Password, and that should be kept safe, offline. Frequent use of Master Key should be avoided.

Thank you.
