Another Bitcoin Halving Is Coming: What it Means For Bitcoin Users

Roughly every four years, Bitcoin undergoes what’s known as a halving event – a routine process written into Bitcoin’s code from its earliest days. Despite their regular nature, these events have often been preceded by increased press coverage, (sometimes) volatile changes to market value and speculation from users and analysts alike.

But what is Bitcoin halving, and how does it impact everyday users? In this piece, we’ll discuss what you need to know about halving – its history, its future and how it will impact the community.

What Are Bitcoin Halving Events?

In short, a Bitcoin halving is an event in which the amount of BTC that Bitcoin miners receive as a reward for their work gets cut in half. But in order to properly understand the process and the potential impact of halvings, you need to know a little about how Bitcoin mining works.

Mining is an integral part of the Bitcoin blockchain’s functionality. It’s a process by which a network of validators use computers and mining hardware to vet and process transactions. When a block of transactions is full, it’s sent to a queue where miners verify the legitimacy of the transactions. At the current rate, miners are paid 6.25 BTC when they verify a block and it is added to the blockchain. The payment is an incentive for them to do the work of validating, recognizing that miners’ roles are integral in keeping transactions smooth and secure.

Bitcoin’s code states that after every 210,000 blocks are created, the mining reward will be cut in half. Given that blocks are added around every 10 minutes, these halving events occur roughly every four years. The most recent instance was in May 2020; but since these events are based on block finalization  – and not a calendar – we don’t know precisely when the next halving will occur. This next imminent halving is estimated to occur on April 20.

Why They’re Significant for the Bitcoin Blockchain

One of the reasons that these events are so important to Bitcoin is its immutability. There is a fixed number of BTC available – 21 million of them. And of that total, more than 19 million of them have been mined to date. Many believe that over time, the increased scarcity of new coins will impact prices in a bullish way. 

The initial reward for miners was 50 BTC, but it’s been halved three times since its inception. First to 25 BTC in 2012, followed by down to 12.5 BTC in 2016 and then to 6.25 BTC during the last halving. These cuts help to decrease the number of new bitcoins introduced as well as to keep inflation low, but it also increases the costs for any given miner to break even on their work. This upcoming Bitcoin halving event is set to reduce block rewards to 3.125 BTC when it occurs. 

The halving policy was written into Bitcoin’s algorithm to help maintain scarcity levels, which makes it a semi-permanent fixture of the protocol. Unlike fiat currencies, Bitcoin’s supply policy and monetary rules are fixed. To make a broad change to any part of the underlying code would require a significant, concerted effort that the Bitcoin community at-large would need to agree to. The “baked-in” status of this process is why it’s important for users to understand the impact a halving has on BTC.

How The Bitcoin Halving Will Impact Users

Technically, a halving event itself doesn’t change anything for users who are just looking to conduct transactions. But there could be ripple-effects that users should be aware of. There’s no way to know how the markets will respond to the next halving, but previous instances have seen some price volatility both in the leadup and aftermath.

But another much-discussed potential impact has to do with block rewards. These rewards are an important part of Bitcoin’s security infrastructure. As they decrease, the potential exists for lowered security.

This is because block rewards are the main way that miners make their money. When they are reduced, the miners’ reliance on profit from transaction fees increases, opening up the possibility that miners may shift processing power away from BTC in order to earn more elsewhere. 

That doesn’t just slow down transactions for users; it could also weaken the system. Generally speaking, the more computing power that’s being directed toward the Bitcoin network, the more difficult it would be to attack. Any bad actors would need to have a similar amount of processing power in order to make moves against the network.

Now, none of this is a certainty. It is equally easy to make an argument for miners to stick around. Today's existing demand – which has surged thanks to a number of recent developments on Bitcoin – has continued to drive up transaction fees as the network experiences more traffic. Especially as subsequent halving events further reduce block rewards, this could incentivize miners to continue their work.

Additionally, Bitcoin halving events have also served as a catalyst for infrastructure upgrades and hardware improvements that have focused on making mining more efficient. This ultimately benefits the Bitcoin mining community and, by extension, the Bitcoin ecosystem in the long run.

Conclusion

The predictable nature of Bitcoin halvings helps to avoid any shocks to the system, but the upcoming event will still be important to follow for crypto enthusiasts. As block rewards are cut again for miners, the importance of protocol growth and mass adoption is thrown further into the spotlight. 

This, ultimately, makes Bitcoin halving events important for users to watch. The advent of Ordinals, BRC-20 tokens, Runes, and other developments have brought more users than ever before to Bitcoin. As we look to future developments on Bitcoin, staying informed about halving events will be essential for any crypto user.
