Overview

A block reward can be explained as the number of Bitcoins the miner receives after successfully mining a single block of Bitcoin. The BTC block reward is based on two components - transaction fees and the newly generated coins. The newly generated coins indicate the supply of new coins that are controlled by the halving event that comes every four years. This event reduces the supply of newly mined BTC in half and it tightens the issue of the supply of Bitcoin when all the 21 million coins are mined by the year 2140. The number of BTCs is forecasted to hit zero until no BTC are left.

About Block Reward

  • Bitcoin block rewards are the newest BTC rewarded to the miners for solving the complex mathematical problem, and for developing a new block for verifying Bitcoin transactions.
  • To do this, the miners utilize a network of nodes and when a new block is created every time it is verified by other miners, then a new mathematical problem is created and the miners need to start again.
  • This block reward offers an incentive for the miners for processing the transactions that are made with cryptocurrencies. It also helps in developing, building, an immutable record of these transactions which is very vital for Bitcoin.
  • BTC uses blockchain which is a decentralized ledger that cannot be tampered with or altered. When it is created, the miners should verify the transactions and they should keep the ledger streamlined up to date.
  • BTC was designed in such a way that new coins can be created consistently. Hence for every 2 weeks, the difficulty of the mathematical problem is adjusted. This ensures a steady output of developing new Bitcoins and that is done every 10 minutes.

    • What will happen when all 21 Million Bitcoins are Mined?

  • One of the consequences for BTC for not taking up the planned cap is it leaves the possibility that the network will be functional even after the year 2140. Even though no Bitcoins will be issued the transaction blocks need to be confirmed thereby offering fees as a primary source of income to the miners.
  • One of the most useful and valuable aspects of Bitcoin is it uses distributed ledger technology as a solution for time-consuming bookkeeping and accounting problems.
  • In the future, if BTC becomes adopted as a medium of exchange, the transaction will go up. When the demand for the coin increases, people might show interest to buy bitcoin in India, through bitcoin exchanges in India as a long-term investment.
  • Presently, 1 bitcoin price in INR is 46,98,938.84 (BTC price INR). If you are looking to purchase, there are the best cryptocurrency exchanges in India like WazirX that offer the best bitcoin price in India to their customers.

    • Bitcoin Block Rewards Future

  • Bitcoin creator Satoshi Nakamoto created the coin with a limited supply of 21 million, to limit inflation. This is the reason why the block rewards are halved every 210,000 blocks which takes 4 years.
  • Since its inception in 2009, every block reward was reduced to half; for example initially it was 50 BTC and in May 2020, the coin was halved to 6.25 BTC. As of May 2021, there are 18.7 million Bitcoins already in circulation and almost 90% of the total supply is exhausted.
  • Currently, miners are rewarded through block rewards. When the entire coins are mined there won't be any block reward for paying miners. When the user executes a BTC transaction a small fee is charged and these fees help the miners rather than a block reward.

    • Summing Up

    Bitcoin has only 21 million in supply cap; this was created by Satoshi Nakamoto for controlling inflation or else might result in an unlimited supply of BTC. Because of this, the halving event has inflated the BTC price by making it a scarce commodity. When it reaches its entire supply, the miners will shift their perspective from block rewards to charging transaction fees as the main source of income.
