Commemorating Bitcoin’s New High

Commemorating Bitcoin’s New High
Bitcoin has just passed its eighth birthday, and its price has finally broken through its all-time high in one fell swoop (8,000 RMB). Let me post a Weibo message to mark the occasion. Today I went to Tsinghua to do a trial lecture, and tomorrow I’ll be at Beijing Normal University giving my postdoctoral exit report. My exit and hiring paperwork are finally nearing completion, and seeing the news of Bitcoin’s new high at this moment is, I suppose, quite fitting. Though I say that in a celebratory spirit, I’m actually rather wistful, because throughout 2016 my judgment on Bitcoin’s market was “buy, buy, buy,” and in just the past…

Internet + Real Estate = Free?

Internet + Real Estate = Free?
The “surge” in property prices in Beijing, Shanghai, and Shenzhen at the beginning of this year was enough to drive one to despair; it felt as if the Chinese economy had completely given up its chance for a soft landing. We all know reform is necessary, but I really do not know where the “turning point” lies. Dragging things on is possible—take North Korea as a reference—but if we really still hope for successful reform, then it is hard to imagine avoiding a collapse. The only remaining suspense is when it will collapse, and who will be the first to collapse. It’s not that I’m being pessimistic about China. I…

The Inevitable Path to Decentralization—A Few Thoughts on Bitcoin Hard Forks, and, by the Way, on Central Bank Digital Currency

The Inevitable Path to Decentralization—A Few Thoughts on Bitcoin Hard Forks, and, by the Way, on Central Bank Digital Currency
Bitcoin is facing the situation that the 1M block size limit is about to become insufficient; a major upgrade is needed. But how should it be upgraded? Different people propose different schemes. If a backward-incompatible scheme is rolled out without reaching consensus, then some people choose the new scheme while others do not update or choose yet another scheme, and the result is what is called a “hard fork.” There was XT a while ago, and more recently there was classic, but in the end a hard fork seems to have been avoided. Many people were probably relieved, but I, for one, feel a certain regret. In my view, a…

Stock Market Musings: Freedom and Stability

Stock Market Musings: Freedom and Stability
Recently China’s stock market has been wildly up and down. After an unprecedented “stock-market crash,” the central authorities have again stepped in with unprecedented force to maintain stability. The reason I thought of writing this article is not to play the prophet and predict market movements. On the one hand, I want to gather together some of my previous statements and thoughts; on the other hand, the stock market also has relations to political philosophy and natural philosophy. Besides, I believe this stock-market crash will have very far-reaching historical significance; in any case, it will become a landmark event. Although I have all along been promoting Bitcoin, and have always…

Why We Don’t Need BitCNY

Why We Don’t Need BitCNY
1、This Is a Revolution, Not an Upgrade BTS is one of the projects in the so-called “second-generation coins” (the full name is second-generation knockoff coins) that has raised the most money (so far) and has the loudest reputation (mainly in China). Whenever I casually take a swipe at it on Weibo, many enthusiastic netizens inevitably come over to “instruct” me, earnestly teaching me that I need to keep up with the times, need to be open and inclusive, need to keep learning… So I usually can’t be bothered to say much. This time, since I’ve been invited to write for 8BTC, I might as well concentrate my complaints here again,…

Copernicus and Nakamoto — A Paradigm Shift in the Technological Revolution

Copernicus and Nakamoto — A Paradigm Shift in the Technological Revolution
This article was submitted last year to Babit, and may have been included in a new book published by Babit. But so far I still haven’t seen it published. Recently, while writing an article, I happened to come across some related content, and remembered that this piece still hadn’t been made public, so I might as well publish it first~ In the earlier Southern Metropolis Daily Bitcoin interview questionnaire, when I reposted it on Babit and Bitren, I added the title “Bitcoin as a Paradigm Revolution.” After all, having a title makes it seem as though it will spread better. But in fact, as a paradigm revolution, it was only…

On CC Licenses
//This piece was commissioned by 8btc. The Bitcoin community is naturally inclined toward the spirit of free software, so it ought to be easier to accept the CC licenses. But copyright awareness in China is generally rather weak, and CC licenses are even less familiar, so plagiarism occurs frequently. Even places like 8btc that have brought up CC licenses still lack respect for them within the community. So some popular explanation is indeed necessary. For the moment it is hard to expect CC licenses to have legal force, but in the long run they are beneficial for fostering an atmosphere of mutual respect and collaboration in the industry, as well…

Bitcoin’s Value Depends on Holding It

Bitcoin’s Value Depends on Holding It
http://zl.yibite.com/point/2014/1011/23952.shtml After several months of doldrums, Bitcoin’s price has recently sunk to a new low, and it is frankly appalling. At a time like this, talking about prices again is perhaps fitting. Of course, I have no intention of predicting Bitcoin’s short-term trend. Although I did not expect it to fall this badly beforehand, it is really not a big deal either; it was always a long-term investment, something to be left there like a pension policy. Besides, over the past year, almost every indicator and performance metric in the Bitcoin world, apart from price, has been developing steadily, so there is nothing to worry about. The reason I am…

Should Bitcoin Exchanges Have 100% Reserves?

Should Bitcoin Exchanges Have 100% Reserves?
This piece was commissioned for the 8BTC special topic: http://www.8btc.com/caution-money After many quiet days, the recent plunge in Bitcoin has finally made the various communities lively again. Quite a few people have popped up to cry, curse, or else gloat for a bit; of course, there are also some calmer players who have come out to reflect on the issues, such as once again reexamining the question of whether exchanges should maintain 100% reserves. Markets rise and fall; that is perfectly normal. There is no need to make a fuss every time prices crash. Short-term coin speculators ought to welcome violent market fluctuations, while long-term hoarders need not care…

Application Scenarios for Bitcoin Multisignature Technology

Web3 & Cypherpunks2014.08.08
Application Scenarios for Bitcoin Multisignature Technology
0. A Brief Introduction to Multisignature Technology Generally speaking, one Bitcoin address corresponds to one private key, and to spend the funds in that address, the holder of the private key must initiate a signature. Multisignature technology, simply put, means that multiple private-key signatures are required for a transaction to be valid. For example, a certain sum of funds corresponds to 3 private keys, and at least any 2 of them must participate in the signing process for the funds to be spent; if only 1 private key signs, it is invalid. This 2/3 arrangement can be extended to any m/n, such as 3/3, 1/5, 6/11, and so on,…
