Discussions on rewriting the code continue

There has been a long discussion about rewriting the dynamic code that runs the Bitcoin blockchain technology, and the results are still undecided. Over the past year, the issue of changing the block size has been a hot topic for us. There is a group of people who are very determined to oppose changing the code, of course, this does not mean that changing the code is necessarily the right thing to do. The review of this matter has caused a rift between those who are in favor of and those who are against increasing the block size, and there will be more discussions on this matter in the future.

The opposition said that they opposed the code modification because the future development direction of Bitcoin is uncertain. Will Bitcoin become the mainstream currency in the financial world, the first choice for daily transactions, or just a means of storing value? Modifying the code will threaten the stability of Bitcoin prices, and more importantly, it will have a decisive impact on its development in the opposite direction. Of course, it is undeniable that modifying the code will improve the security of Bitcoin. We must think twice before acting on this matter, after all, it concerns the future of Bitcoin. Virtual currency exists on mathematics, and behind its development, there is a strong scientific force as support.

In 1994, Shor proved that an effective quantum algorithm can be used to calculate discrete logarithms, and quantum computing began to take shape. His proof showed the world that quantum computing may one day abolish cryptographic systems. Shor's algorithm can easily crack RSA, Diffie-Hellman and elliptic curve cryptography (ECC) running on computers. The National Security Agency (NSA) has been working on building quantum computers, and it is no secret that they are trying to snoop on users' private information from the Internet. According to former NSA employee Edward Snowden, the rumors that they are trying to build quantum computers to crack passwords are not groundless. So far, the largest number that quantum computers can analyze is 143, but Snowden said that the NSA has invested 79 million in a project called "Penetrating Hard Targets" to tackle the difficulties in quantum computing, which is still a considerable threat. The NSA said this summer that they urged the project team to speed up the research progress.

The NSA published in 2015: "Users use layered commercial encryption to protect their privacy. This primitive method has its limitations. We should try to study quantum protection schemes."

None of this means that Alice and Bob's actions are over. But it shows that rewriting the Bitcoin code may not be such a bad thing. This is easier said than done. People who use censorship to support their own opinions are ignorant. We may make irrational decisions without careful discussion and thinking before we act. Changing the block size may really be necessary. ECDSA may change drastically one day and become unrecognizable. One possible way to solve this problem is to use Litecoin as a "guinea pig". Litecoin can be a pathfinder for Bitcoin and help Bitcoin test the way forward.

  It is essential to discuss the impact of increasing the block size on the speed of Bitcoin transaction process. The ECC vulnerability poses a great threat to the future of Bitcoin. We must fix the vulnerability before an accident occurs, otherwise we will regret it. The property of dynamic software is that it changes all the time. The biggest taboo of technological innovation is to remain unchanged. Today, the discussion of block size is still going on. In the near future, we may start to discuss the threats to the cryptographic system itself. Perhaps, it is time to start now.
