Hello everyone,
I'm very happy to participate in this begginer's course on our beloved #steemitcryptoacademy. I'm very grateful to the organizers and our crypto-professor @sapwood for the wonderful lecture.

This post is solely focused on the homework task given by our crypto-professor as it's slated below and the post is free from plagiarism and purely original.

• WHAT IS POB
• WHAT DOES CURATION MEANS TO YOU IN STEEMIT BLOCKCHAIN.
• WHAT IS THE BENEFITS OF BUILDING UP OF SP
• HOW DO YOU EXPLAIN SELF-VOTE AS A GOOD OR BAD HABIT AND WHY?
• EXPLORE THE COINMARKETCAP.COM TO INDICATE THE RANK, STEEM PRICES, AND COINMARKETCAP.
• WHAT ARE THE DIFFERENT COINS, ONE EARNED FROM SOCIALIZE WITH STEEMIT BLOCKCHAIN.

WHAT IS POB?

POB is an acronym that can stand for two separate but related terms in blockchain technology. POB Can be for Proof of Burn or Proof of Brain. Proof of Burn is a consensus mechanism in which slated token are "burn" or sent to a wallet generated and those tokens remains unused to keep the system working while proof of brain is a reward mechanism. Specifically, in steemit, it solely stand for Proof of Brain.
Moreover, POB is a reward system attached this social media platform where the users are rewarded with tokens unlike other social media platforms like Facebook where the users did not benefit anything from the rewards. POB is very different from the consensus mechanism of steemit which is DPOS. that's combines the mechanisms of proof of work (POW) found in Bitcoin, Litecoin etc and proof of STAKE (POS) Which is unique with Ethereum etc.

Proof of Brain simply refers to the earning of currency from our brain. It is also refered to as TASK-BASED. In that task should be monotonous and involves content creation or publishing, proper engagements with contents like meaningful comments, replies and curation, even helping in content discoveries to keep the system from from plagiarism and grammar check. A good content created should be original and mostly from the workability of the human brain to be rewarded with a token. These tokens are highly scalable and tradable.

However this is a unique type of reward mechanism where good content are curated with a token rewards. The rewards are derived from the "upvote" approach but the other which is downvote. The upvote approach is similar to "like" mechanism in other social media platforms but here, upvote is how the rewards mechanism are distributed and post upvoted will receive a stipulated reward from the reward pool depending on the stake weight (steem power; sp) of the upvoter while the downvote helps to redistribute the rewards in the pools as the rewards flow back from the post that's downvoted. The amount of token that will flow back into the reward pools for redistribution depends of the percentage of the stake weight (i.e; sp) of the downvoted.

WHAT DOES CURATION MEANS TO YOU IN STEEMIT BLOCKCHAIN

Steemit is a unique platform that encourage good contents creation in the Blockchain. These good contents are rewarded in the form of tokens. These rewarding mechanism typically for steemit is termed CURATION

These rewards curation can be derived in two forms:

• CURATION REWARD
• AUTHOR REWARD.

CURATION REWARD.

Steemit is a stake weight based reward platform in that a content is rewarded mostly on the steem power of the users. When various users combined their stake weight together as in a community and upvote a post. During the post pay-out, the rewards will be distributed among the individual users in that combination but based on their personal staked weight. The rewards from this option is called "CURATION REWARD" while the combination of various staked weight is referred to as CURATION TRAILS.

AUTHOR REWARD.

The rewards from the good content which can be post, replies, comments etc that's curated or upvoted by various users, communities or #steemcurators is referred as the AUTHOR REWARD. The amount of tokens curated is based on the percentage of the staked weight (i.e, sp) of upvoters.

WHAT IS THE BENEFITS OF BUILDING UP OF SP?

SP is a short term for steem power. It is the influence power in the steemit. The more, one accumulates the steem power in the wallets, the more, the rewards will be derived. Since the distribution of the rewards is related closely with the staked weight (i.e, sp) of the user.
For instance, look at the curation rewards of these two users; me, @sammylinks and you, my seasoned crypto-professor @sapwood with different steem power.

A SCREENSHOT OF THE WALLET

From the screenshoted pictures above, it is clear that the rewards of the two users is very different due to the amount of the stake weight or steem power built up by them.

Another recent advantage of building up of the so is the offer to participate in the ongoing #cryptoacademy. Not having a certain amount of sp will never participate in the academy and there will be no homework task from such user that does not merits the requirements will be curated.

However, the stake weight of a user determine the voting power subject to their voting Mana. Any user with higher sp that upvote a post 100% will be higher than the user with lower sp that upvote a post at that 100% too. The influence power of any user is absolute based on their so and staked weight. It is one of the reasons to build up the sp.

Steem power is needed to interact freely with the steemit blockchain. Although steem is fee-less token but to interact meaningful with the Blockchain, it requires resources to be used. This resources is called the resources credit based on the computational algorithm of the steem blockchain. Without these resources credit, users can't freely interact with the system. FROM 15sp and above have enough stake weight to socially freely.

There are two basic ways of building up the sp.

• Since steem are transferrable, one can receive more steem and "power up" the entire accumulated sp. This will boast it's sp or stake weight in the wallet.

• Setting all the post at 100%, the entire reward will pay out as sp and thereby building up the sp.

HOW DO YOU EXPLAIN SELF-VOTE AS A GOOD OR BAD HABIT AND WHY?

Self-vote is when one decides to upvoting the one's post or group decides to be voting for themselves. It is a bad habit because of these reasons:

A SELFISH ACT:

It's really a bad and selfish act because it affects the content discoveries which is based on good decisions of others to vote. Assuming a user with 10sp voting for himself, will get the 10% sp on the interest rate without even being judged on the quality of contents creation.

BASED ON CONVERGENT LINEAR REWARD.

Self-vote contents falls below sub-linear zone and should be rewarded very low because the principle behind this linear zone encourage fully and meaningful engagements with other user's content to promote the system and revitalize the rewards mechanism.

According to these reliable source of the cryptocurrencies market, STEEM IS RANKED #274 and the prices at the stipulated time is $0.2244 with market capitalization of over 89 million US Dollars with 6.20% increase.

The daily all time high of $0.2409 and low of $0.2023 of the prices of the steem within 24 hours while the Total supply is over 417 millions steem and current circulating supply is over 400 millions steem.

WHAT ARE THE DIFFERENT COINS, ONE EARNED FROM SOCIALIZE WITH STEEMIT BLOCKCHAIN.

Steemit is a rewarding platform and rewards good contents with three wonderful tokens. They Includes:

STEEM

This is the native coin of this wonderful blockchain technology. Steem rewarded from due post of 7 days can be tradable or used to increase the stake weight (i.e, sp) of the user's wallets. These steem power in the vesting mechanism helps to get more rewards and influence in the system. Steem in the vesting can be powered down quarter of the total amount in one week.

#SBD

It is another unique token that is rewarded by the steem blockchain but it is pegged at One US Dollars (1SBD = 1USD). It always been influenced by the purchasing power of the dollar. It's highly scalable and tradable.

TRX

Since the integration between steemit and Tron blockchain, steemit users can earn TRX as one of the token from this blockchain technology. This rewards mechanism pegged 1TRX : 1STEEM. THATS MEANS THAT AS A POST IS PAYED OUT AT STEEM, A Corresponding Trx is earned too from the socialization on steemit blockchain.

CONCLUSION

Steemit blockchain is a wonderful social media platform that rewards it's users with a valuable tokens. These tokens are highly scalable and tradable and can be in three forms: Steem, SBD AND TRON.

There's a unique mechanism to share the rewards in the pools as POB. Although, not a steemit type of consensus mechanism but it's rewarding system and the building up of the stake weight is very important to increase the influence power.
