BTC was still hovering below 100k over the weekend. The past week was the week when $100,000 came true. "12.8 Teaching Chain Internal Reference: In the 49th Week, the big pie broke six figures for the first time, and the new director of the White House showed his ambitions" reviewed this.

One ​​BTC costs 100,000 dollars, which indeed makes ordinary retail investors feel that it is not cheap. However, did you know that according to the halving algorithm stipulated in the Bitcoin system code, it will take about 35 years for the last Bitcoin of the total upper limit of 21 million BTC to completely stop issuance in 2140? can be mined.

The above picture is the timetable for the halving of BTC production. After each production cut, 210,000 blocks will be mined, which takes about 4 years. A simple calculation shows that from the production reduction in 2104 until the complete stop of production in 2140, the total number of BTC that can be produced is:

(298+149+74 +37+18+9+4+2+1) * 210000 / 10^8 = 1.2432

Now, the global BTC network already has a computing power of approximately 800EHash/s. 800EHash/s means that 800 x 10^18 hash numbers can be calculated in one second, that is, 800,000,000,000,000,000,000 hash numbers.

According to research, the current number one supercomputer in the world is El Capitan in the United States. It has over 1.7 EFlops (1.7 × 10^18 floating-point operations per second) performance.

According to Chapter 53 of Chapter 11 of "Bitcoin History" by Jiaolian, "The computing power unit of supercomputing is FLOP/s. According to Satoshi Nakamoto and netizens previously made a rough estimate of the actual measured data of CPU computing power. The floating point computing power of a general-purpose computer converted into hash computing power needs to be reduced to about one ten thousandth of the original value. In other words, every 10,000 floating point computing power (10,000 FLOP/s) is approximately equivalent to 1 hash power (1 hash/s) ‖

In other words, the computing power of the world's largest supercomputer is approximately equivalent to 1.7 x 10^14 Hash/s.

800EHash/s, roughly equivalent to 5 million such supercomputers.

When Jiaolian wrote "Bitcoin History" in 2020, the world's fastest supercomputer was Japan's Fugaku (approximately 442 PFlops/s). At that time, the computing power of the entire BTC network was only 100EH/s, which was approximately equivalent to 300 EH/s. Four years later, the computing power of 10,000 supercomputers has increased to 3.8 times, and the computing power of the entire BTC network has increased to 8 times.

Supercomputing technology is advancing. But BTC computing power technology is progressing faster.

This only examines the dimension of computing power, not the Dimensions of energy consumption

When writing "Bitcoin History" in 2020, Jiaolian made an estimate of energy consumption and wrote: " And if you really use 300 Tens of thousands of supercomputers, not to mention whether there are enough funds for production and manufacturing, will consume 30,000 times the power consumed by Bitcoin mining today in terms of power consumption alone, which is not feasible. ‖

In the past four years, the development of BTC computing power has further widened the gap with supercomputing. The energy consumption gap is probably widening further, right?

So we say that the security of BTC does not stay at the abstract and logical level, but is implemented at the material and energy level that humans cannot override!

Nothing else can beat the computing power of the BTC network to protect the security of all BTC at a lower cost. This sentence is already a solid objective fact.

BTC may not yet be the asset with the largest market value among all forms of human wealth, but it is already the safest asset.

Now look back and think about the question at the beginning of this article, that is, with the computing power of the entire BTC network being so huge and the computing power being even bigger in the future, how can the poor It took 35 years just to create the last BTC.

How much is such a BTC worth?

Worth it, or not.
