The mathematics of Bitcoin halvings: Cracking the equations and formulas

The role of halving events in Bitcoin’s scarcity mechanism and inflation control

“Bitcoin’s design includes a regular halving process, which helps keep the supply of this cryptocurrency limited and protects it from the negative effects of inflation.”

Bitcoin’s code includes a built-in mechanism called halving, which happens roughly every four years. During this event, the reward for mining a new block of Bitcoin gets reduced by half. Consequently, the production of fresh Bitcoin gets affected.

Halving events in Bitcoin serve to increase its scarcity by decreasing the speed at which new coins are produced. This fixed and restricted total of 21 million coins contributes to Bitcoin’s enduring value proposition.

Reducing inflation is another benefit of Bitcoin’s halvings. This process slowly cuts down the generation of new Bitcoins, making its supply more controlled and steady. In contrast, traditional fiat currencies experience unpredictable inflation due to central banks’ ability to print more money whenever needed.

The Bitcoin money supply equation The Bitcoin money supply equation formula provides a theoretical maximum supply. In reality, some early mined BTC might be lost, resulting in a slightly lower circulating supply.The Bitcoin money supply equation formula can be seen in the image below:In the given equation, “Sigma” represents the total of adding up the Bitcoin reward amounts throughout all the bitcoin halving events.i: An index variable that represents each halving cycle.0: The summation’s starting point represents the first (genesis) block.i=0^32: This defines the range of the summation.^32: The summation’s upper limit, indicating the 32nd halving cycle. Since counting starts from 0, this includes a total of 33 halving cycles (0 to 32).50: This is the genesis block’s initial block reward (50 BTC).(1/2)^ (i/210000)): This represents the block reward for each halving cycle.(1/2): This represents the halving factor, where each reward is divided by two at each halving event. This is why it’s raised to the power of -1 (1/2 is equivalent to two raised to the power of -1).(i/210000): This exponent accounts for the number of halving cycles that have occurred. As ‘i’ increases with each cycle (from 0 to 32), the exponent ensures the reward is halved at the appropriate intervals (roughly every four years).

The math behind the Bitcoin halving A few core concepts like the block reward, halving equation and exponential decay form the basis for the mathematical foundation of Bitcoin halving.An intriguing illustration of economics being governed by code is the Bitcoin halving mechanism. Essentially, this concept revolves around the block reward – the amount of new Bitcoins granted to miners for verifying transactions and appending a new block to the blockchain. When Bitcoin was created, this reward stood at 50 Bitcoins. Over a period approximately every four years, this reward is reduced by half.A straightforward yet effective equation controls this reduction: The block reward is determined by the formula: 50 decreasing every 210,000 blocks mined since Bitcoin’s creation.The exponential character of this equation is what makes it enchanting: With each addition of 210,000 blocks to the blockchain, the block reward decreases exponentially. Consequently, the reward was reduced to 25 BTC following the first halving, then to 12.5 BTC after the second, and so forth. This built-in decline mirrors the increasing intricacy and expense of mining precious metals, where resource extraction becomes more challenging and costly over time.The Bitcoin system’s mechanism for cutting in half the number of new coins created over time has major consequences. It creates an inherent scarcity by slowing down the rate at which new Bitcoins become available. Furthermore, the value of Bitcoin as a long-term investment is strengthened due to its limited supply and consistent production schedule.

How to calculate the approximate time between Bitcoin halving events

It’s impossible to know the precise moment for a Bitcoin halving event, but an approximation is possible.

Bitcoin’s coding creates a new block every ten minutes on average. Halvings take place after the production of 210,000 blocks, not based on a particular time or date. A rough estimate can be obtained by this simple calculation: 210,000 blocks multiplied by 10 minutes per block equals 2,100,000 minutes.

To find out how long 2,100,000 minutes is in terms of years, first calculate the number of hours and then the number of days: 2,100,000 minutes / (365 days a year * 24 hours a day * 60 minutes an hour) = approximately 4.19 years. So, this amount of time is roughly equal to four years and two months.

In the real world, the time between each block halving can deviate from the average four-year mark due to the fact that the production rate of blocks is not constantly set at 10 minutes. Fluctuations in the total computational power of the network can lead to slight acceleration or deceleration of the process.

Potential impact of Bitcoin halvings on cryptocurrency adoption

The upcoming halving of Bitcoin supply could generate excitement, drawing in fresh investors and increasing the cryptocurrency’s prominence in the market.

During a cryptocurrency halving, the Bitcoin community might experience heightened excitement and eagerness. The heightened interest surrounding these events often leads to an increase in Bitcoin demand and potential price fluctuations.

People might become more curious about Bitcoin and cryptocurrencies as a whole because of market activity, which could increase their visibility to the public. While it’s unclear how the halving will specifically impact prices, Bitcoin’s value as a digital asset is enhanced in the growing world of cryptocurrencies due to its distinct economic structure that’s highlighted during these events.

In addition, Bitcoin’s focus on restricted availability, moderate price increases, and rarity makes it an alluring option versus traditional currencies and other digital currencies, possibly drawing in more diverse groups of individual and institutional investors.
