What is a Mining Reward?

The meaning of mining reward, in the context of cryptocurrency, refers to the amount of cryptocurrency that is given as a reward for successfully mining a block of transactions. Mining is the process of verifying transactions on a blockchain network and adding them to the blockchain. To incentivize people to perform this important work, the network rewards them with a set amount of cryptocurrency for each block they mine. This reward is known as the mining reward.

The mining reward serves several important purposes. First, it helps to secure the network by incentivizing people to contribute computational power to the network. The more computational power the network has, the more secure it is. Second, it helps to distribute new coins into circulation. As a cryptocurrency network grows and more people participate, the reward for mining new blocks decreases over time, slowly reducing the overall supply of coins.

The size of the mining reward can vary depending on the cryptocurrency and its underlying blockchain. For example, in Bitcoin, the reward for mining a block was initially 50 Bitcoins, but it halves every 210,000 blocks mined. As of 2021, the reward for mining a block in Bitcoin is 6.25 Bitcoins. In other cryptocurrencies, the reward for mining a block may be fixed, or it may be tied to the computational power being contributed to the network.

In an analogy, the mining reward can be compared to a scavenger hunt prize. Just like how participants in a scavenger hunt work to find hidden treasures and earn rewards, miners in a cryptocurrency network work to verify transactions and earn rewards in the form of cryptocurrency. The reward for successfully mining a block is like the prize for finding the hidden treasure in the scavenger hunt.

Simplified Example

A mining reward is a type of prize or payment that a person can receive for helping process transactions in a cryptocurrency network. Think of it like finding a surprise treasure in a game.

Imagine playing a game where you are looking for hidden treasure with your friends. You all search for the treasure together and when you find it, you divide the prize equally among all of you. This is similar to how a mining reward works in a cryptocurrency network.

The History of Mining Reward

In the early days of Bitcoin, mining was primarily a process of solving complex mathematical puzzles to validate transactions and secure the network. Miners who successfully solved these puzzles and added a new block to the blockchain were rewarded with a specific number of newly created bitcoins, known as the mining reward. This reward served as an incentive to encourage miners to contribute their computational power to maintain the network's security and integrity.

The history of the term "mining reward" is intrinsically linked to the foundational design of blockchain consensus mechanisms, particularly proof-of-work, where miners invest computational resources to secure the network and are compensated with newly generated cryptocurrency. Over time, as block rewards decrease according to predetermined schedules and network protocols, mining rewards have evolved, becoming a critical element of the economics and sustainability of various blockchain networks.


For example, if the mining reward for a specific cryptocurrency is 10 coins, then a miner who adds a block to the blockchain will receive 10 coins as a reward.

Another example is the mining reward for Bitcoin, which was originally 50 coins per block. Over time, the reward halves every 210,000 blocks, so the current mining reward is 6.25 coins per block.

In a third example, a cryptocurrency with a smaller network might have a smaller mining reward, such as 2 coins per block. This incentivizes miners to join and support the network, and it helps to maintain the security and stability of the blockchain.

  • Mining: Mining in cryptocurrency refers to the process of verifying and adding transactions to a blockchain network.

  • Miners: Miners, in the context of cryptocurrency, are individuals or groups of individuals who use specialized software and hardware to validate transactions and add them to the blockchain.
