## The Security Cornerstone of the Bitcoin Network from the Perspective of Computing Power

When it comes to cryptocurrency mining, one core metric cannot be overlooked - **hashrate**. This seemingly complex concept actually measures how many hash calculations mining equipment can complete per second. For proof-of-work systems like Bitcoin, hashrate not only represents the network's computing power but also determines the overall security and stability of the ecosystem.

## Decisive Factors in Mining Competition

In the Bitcoin network, the miners have a clear goal - to find a hash value that meets specific conditions to validate new blocks. This process requires a large amount of mathematical calculations, and the speed at which these calculations are completed is reflected by the hash rate. It is typically expressed in hashes per second (H/s), with larger units including MH/s, GH/s, and TH/s.

A simple fact is: the higher the hash rate, the greater the probability that miners will successfully mine a block. When miners successfully validate a block, they receive a reward for that block. Currently, the block reward for Bitcoin is 6.25 BTC, but this number will decrease to 3.125 BTC with the halving event in 2024. This means that having stronger computing power becomes even more critical in the face of reduced rewards.

## The Evolution of Computing Power in the Bitcoin Network

Since the birth of Bitcoin, the growth of its Computing Power has been spectacular. In the early days, it was possible to mine using a regular computer, but with the development of the network, this has become a thing of the past.

Milestones throughout history have recorded this evolution:
- Broke through 1 TH/s in 2011
- Reached 1000 TH/s in 2013
- In 2016, it rose to 1,000,000 TH/s
- Jumped to 10,000,000 TH/s in 2017
- Increased to 60,000,000 TH/s in 2019
- 2020 broke 100,000,000 TH/s
- Reach 400,000,000 TH/s by 2023
- As of November 2023, it has stabilized at around 460,000,000 TH/s.

This exponential growth reflects the revolution of professional mining equipment. The advent of ASIC miners has completely changed the rules of the game, and ordinary consumer-grade hardware can no longer compete with it.

## The Relationship between Mining Economics and Network Security

The rise of hash rate is closely related to the health of the Bitcoin network. A higher total hash rate means that more resources are required to attack the network, which increases the security of the system. At the same time, under the mechanism of automatic mining difficulty adjustment, the network maintains a relatively stable block time.

For mining pools, their competitiveness entirely depends on how much Computing Power they can gather. Miners choose to join a certain pool, essentially gambling that this pool can find blocks more frequently and distribute rewards.

## Understanding the Core of Proof of Work

The importance of hash rate is not limited to mining economics. It is an unavoidable concept when understanding the Proof of Work consensus mechanism. The network's difficulty, hash rate, and security form a tight triangular relationship, and any change in one variable will affect the other two.

## Summary

**hashrate** is key to understanding Bitcoin and other proof-of-work blockchains. It reflects the development level of mining hardware and determines miners' expected earnings. From early CPU mining to the specialization of the ASIC era, the growth of hashrate has witnessed the evolution of the entire industry.
