NFT is blooming. Naval’s insightful viewpoints about NFTs as follow: An NFT is a unique, on-chain token representing ownership of an off-chain asset. The token is backed by a social contract from its creator and a surrounding community. By assigning a unique token to a thing, its ownership (not the thing itself!) becomes programmable, verifiable, divisible, durable, universally addressable, composable, digitally secured, and easy to transfer. Bitcoin and other completely on-chain assets are provably scarce - scarcity is enforced by code and distributed consensus. Off-chain assets represented by NFTs are not provably scarce. The promise of scarcity is a slender thread, only as strong as the social contract with the creator and interwoven with the backing of the community. An NFT’s creator may break their promise, or be unable to enforce it, or may have picked the wrong underlying platform and community - rendering the NFT worthless. For NFTs representing digital art and collectibles, the creator cannot enforce scarcity - it’s up to a surrounding community to imbue the authorized NFT with scarcity and prestige within the context of that community. Just as HODLers imbue Bitcoin with value, and developers infuse Ethereum with value, collectors, admirers, and users imbue NFTs with value. NFTs gain value when displayed, used, and promoted within vibrant and growing communities. If the community around an NFT is dying, the NFT is likely bleeding value. If the community is surging, the NFT is likely gaining value. NFTs are monetized memes.* “Actual-value NFTs” can draw upon legal and code-based contracts - a song token can provide a royalty stream, a ticket token can provide access, a metaverse token can grant land titles, an item token can have in-game powers, an ISA token can provide a cut of creator earnings. Even “actual-value NFTs” require a social contract with the creator and community to transfer the value from the off-chain contracts onto the chain where the NFT is registered. Just as there are those who won’t accept that mere consensus can create digital gold, and those who won’t accept that mere smart contracts can create a decentralized Wall Street, there are those that won’t accept that digitized social contracts will create valuable tokens. As with most art and most tokens, most NFTs will have very little value. But a select few NFTs will become focal points for communities who gather to celebrate art, build collections, and explore virtual worlds. With NFTs, blockchains make the jump from finance into creative applications. Regulators would do well to recognize that blockchains are the next generation of the Internet, and applying financial regulations to NFTs is a category error. NFTs tokenize all the things. We are going from a world where every protocol has a token, to where every (decentralized) application has a token, to where every valuable digital representation of an object or person has a token. Public blockchains will be the title registries for everything of value. Ultimately, NFTs will authenticate the world.**

背景 首先，先看看这个新闻： 湖南益阳62岁老人投江后续：当地多家养老机构爆雷，有老人获悉后心梗去世。 由这个新闻想到中国从2018年开始了一系列爆雷： P2P爆雷断断续续到现在还没有结束 民营企业债爆雷 国有企业债爆雷，如永煤，华晨，北大方正，清华紫光 房地产全线爆雷，如北京院子，北京山水等等，还有很多烂尾楼 养老机构爆雷，如益阳市纳诺老年公寓 教育机构爆雷，如学霸君 共享单车爆雷，如OFO 黄金爆雷，如武汉金黄 信托爆雷，如四川信托 股票爆雷，如獐子岛 银行爆雷，如包商银行 爆雷背后是什么？ 爆雷其实是骗局的破灭。破灭是由于业务与模式的不可持续，不可持续由于缺少接盘侠。 上面列举几种爆雷，其实都是缺少接盘侠（中国居民负债率在2019年就超过了50%）。典型的例子是泰和北京院子与恒大地产。 恒大地产有了接盘侠，撑过来了，而泰和没有接盘侠，北京院子就烂尾了。 ...

The difference between stupidity and genius is that genius has its limits. We all know that light travels faster than sound. That’s why certain people appear bright until you hear them speak. The only thing that interferes with my learning is my education. Education is what remains after one has forgotten everything he learned in school. The majority of the stupid is invincible and guaranteed for all time. The terror of their tyranny, however, is alleviated by their lack of consistency. Only two things are infinite, the universe and human stupidity, and I’m not sure about the former. Common sense is the collection of prejudices acquired by age eighteen. Men marry women with the hope they will never change. Women marry men with the hope they will change. Invariably, they are both disappointed. Any man who can drive safely while kissing a pretty girl is simply not giving the kiss the attention it deserves. If A is a success in life, then A equals x plus y plus z. Work is x; y is play; and z is keeping your mouth shut. The equation for ego is: One over Knowledge. With fame, I become more and more stupid, which of course is a very common phenomenon. People are like bicycles. They can keep their balance only as long as they keep moving.（Life is like riding a bicycle. To keep your balance, you must keep moving） Intellectuals solve problems, geniuses prevent them. The hardest thing in the world to understand is the income tax. Whoever undertakes to set himself up as a judge of Truth and Knowledge is shipwrecked by the laughter of the gods. As a human being, one has been endowed with just enough intelligence to be able to see clearly how utterly inadequate that intelligence is when confronted with what exists. When you are courting a nice girl an hour seems like a second. When you sit on a red-hot cinder a second seems like an hour. That’s relativity. The only reason for time is so that everything doesn’t happen at once. If you are out to describe the truth, leave elegance to the tailor. You see, wire telegraph is a kind of a very, very long cat. You pull his tail in New York and his head is meowing in Los Angeles. Do you understand this? And radio operates exactly the same way: you send signals here, they receive them there. The only difference is that there is no cat. If I had an hour to solve a problem, I’d spend 55 minutes thinking about the problem and 5 minutes thinking about solutions. If you want to live a happy life, tie it to a goal. Not to people or things. I must be willing to give up what I am in order to become what I will be. Mathematics is, in its way, the poetry of logical ideas. It is not that I’m so smart. But I stay with the questions much longer. You Don’t Have to Know Everything. You Just Have to Know Where to Find It. Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world. A clever person solves a problem. A wise person avoids it. A happy man is too satisfied with the present to dwell too much on the future.
