What Are Crypto Mining Block Rewards, and Why Are They Important?

Reading Time: 4 minutes

Crypto mining blocks are vital, but how do they work?

Crypto miners are very important. They are responsible for creating new crypto tokens, validating transactions on the blockchain, and much more tasks using sophisticated software and hardware.

However, they do not do this for free, as there is an incentive: block rewards. So, what is a block reward, and why is it significant in cryptocurrency?

What Is a Block Reward?

Transactions on a crypto network exist in ‘blocks’ and are linked together in ‘chains’ (hence, ‘blockchain’). To prevent fraudulent transactions on the network, miners thoroughly check all the transactions in a block using highly sophisticated computers to ensure they are valid.

The crypto network rewards them for their work through block rewards in the form of native crypto tokens. So, for example, when cryptocurrency miners on the Bitcoin network successfully mine a block, they get rewarded in Bitcoin tokens.

How Do Block Rewards Work?

Whoever is the first to hash the data blocks, solve the complex puzzle, and get the answer right wins the block reward. However, several miners can form mining pools to mine faster, even though the block rewards will be lesser per individual. Note that the mining difficulty of a cryptocurrency determines the mining duration and required energy.

Blockchain networks achieve two things through the block reward systems. One is that the network is protected from fraudulent transactions called double-spending. The second is that new tokens are circulated after a block is successfully mined. The block rewards vary from network to network, meaning the rewards for mining Bitcoin differ from that of mining other proof of work (PoW) cryptos.

The Top 5 Blockchain Block Reward Systems

Every cryptocurrency network has a block reward system, but not every crypto uses mining to deliver those block rewards. However, when you mine, the block rewards you receive and the timing for halving (a preprogrammed event where rewards are cut in half after mining a specific number of blocks) are different across crypto networks.

Here are the block reward systems for some top cryptos.

1. Bitcoin

Miners on Bitcoin earn 6.25 BTC for every block they successfully mine. Bitcoin halves its block reward every 210,000 blocks—approximately every four years. The next Bitcoin halving event, where the reward will reduce to 3.125, will occur at block 840,000, possibly in 2025.

In addition to block rewards, Bitcoin miners are also paid transaction fees for the transactions in the block. As block rewards reduce, these transaction fees will constitute a bigger percentage of the mining rewards.

2. Dogecoin

When miners hash a block of transactions on the Dogecoin ecosystem, they receive 10,000 DOGE and the transaction fees associated with the block. However, these transaction fees are typically much lower than the block rewards; usually, transaction fees are less than 1% of the total rewards miners earn.

Initially, Dogecoin halved its mining rewards after every 100,000 successfully hashed blocks. However, after the last halving event in 2015, the blockchain suspended halving events.

Before this suspension, Charlie Lee, Dogecoin’s creator, proposed the Scrypt algorithm that would allow Litecoin or other Scrypt coins to be used in mining Dogecoin. This proposal, implemented in 2015, was designed to increase Dogecoin’s total hashrate and mining profitability. In addition, because Litecoin and other Scrypt coin miners can contribute to the Dogecoin network, they can confirm blocks faster, and Dogecoin has an unlimited supply of DOGE tokens.

3. Litecoin

Litecoin miners earn 12.5 LTC tokens per block. They also earn transaction fees per block.

Litecoin’s reward per block is halved every 840,000 blocks—four times that of Bitcoin. Litecoin’s next halving event will likely occur in August 2023 (around block 2,520,000), and the block reward will be halved to 6.25 LTC per block. As opposed to Bitcoin’s total supply of 21 million BTC tokens, Litecoin has a total supply of 84 million—four times more than Bitcoin’s.

4. Monero

Monero enables P2Pool, pool, and solo mining. All the mining methods receive a constant block reward of 0.6% XMR and users’ transaction fees per block.

Unlike other PoW blockchains, Monero maintains a constant block reward, so miners do not have to rely on transaction fees as the only source of rewards.

5. Ravencoin

As a Bitcoin fork, Ravencoin shares numerous similarities with Bitcoin. Like Bitcoin’s 21 million coin supply, Ravencoin has a total supply of 21 billion tokens. Similarly, instead of halving every 210,000 blocks, Ravencoin’s halving event will occur every 2,100,000 blocks.

The blockchain’s first halving event occurred on January 11, 2022, and the reward block dropped from 5,000 (like Bitcoin’s initial block reward of 50 BTC) to 2,500 RVN (Ravencoin’s utility token). Miners will earn 2,500 RVN until the next halving event at block 4,200,000—probably in 2026. It is unclear whether miners would receive rewards from transaction fees, as in other PoW blockchains.

3 Factors That Affect Block Rewards

The following are the factors that affect block rewards:

1. Crypto Token Price: Block rewards depend on the price of the tokens. The value you’ll get after mining a block is directly proportional to the price of the crypto token at that particular time. The higher the token’s price, the more profits you’ll earn.
2. Halving: Halving controls the rate at which new coins are mined and pushed into circulation, thereby creating a relative scarcity and consequently driving the value of the crypto up. As a result, on average, block rewards reduce by half every four to six years or after a specific number of blocks have been created.
3. Rate and Mining Difficulty: The faster you hash a block, the more block rewards you earn. That is why most miners come together to form pools so that they can mine at a faster rate and earn more money. Investing in mining rigs with high hash rates, such as the ASIC miner, is also important.

3 Benefits of Block Rewards

Block rewards have benefits for miners and the blockchain network in its entirety.

1. Financial Reward: Crypto miners earn their daily living from their mining activities. They earn crypto tokens with every puzzle they solve, which they can exchange for fiat money.
2. Network Security: Alongside earning rewards, verifying transactions, and checking for double spending, miners secure the blockchain network.
3. Increase in Investment: Block rewards tend to boost investment in cryptocurrencies, which boosts crypto adoption. With each passing day, blockchains become more popular. The process also creates new crypto coins, which ensure a continuous supply.

Crypto Block Rewards Remain a Vital Incentive

Without crypto block rewards, engaging crypto miners, crucial to confirming transactions and securing PoW blockchains, would be difficult. Crypto mining is typically a tasking and pocket-draining venture. However, crypto block rewards turn this venture into a road to financial freedom for miners.

If you’re a crypto enthusiast, crypto mining is another way to earn money, especially because crypto block rewards are up for grabs.
