Roast boy observation: wēi? wéi! wěi? wèi?
For practitioners in the blockchain industry, whether it’s Satoshi Nakamoto, who never sees the end of the dragon, or V God, who became famous at a young age, it seems that everyone can tell a few paragraphs of gossip about them. But there is another name, which seems very familiar and familiar to us. It is so familiar that you will see him once in every operation. When DeFi was hot some time ago, it "doubled its value" accordingly.
But if you think about it carefully, all the information about him seems to be very vague. What did he do? How important is he in the crypto world? How is his life? Regarding all kinds of information about him, it seems that even the most senior "old man" doesn't know much about him, and everyone's impression of him is so vague that even the correct spelling of the name has different answers.
Who is so mysterious? Let's start from the beginning.
Friends who have used Ethereum must have seen "Wei".
The smallest unit of ETH is Wei, 1 ETH = 10 to the 18th power, but do you know why it is called "Wei"?
This "Wei" refers to the "Wei" of David (Wei Dai)
This is God V to pay tribute to David and thank him for his contribution to digital currency.
Not only that, the "b-money" white paper released by David was even quoted by the "top stream" in the currency circle - the white paper of Bitcoin.

If you've ever Googled him, you've come across this photo referenced in his Wikipedia profile.
Even some media used this photo provided by Wikipedia as David's photo when reporting or recording the past glory of the blockchain.

Once a person is mysterious, there will be more rumors.
It is rumored that David's father was Dai Xiwei, the only accompanying person of Microsoft's Bill Gates on his first visit to China. He used to be the highest-level Chinese in the IT industry in the United States, and held an important position in Microsoft. David, who graduated from the computer science department of the University of Washington in the United States, "inherited his father's career". He also worked for Microsoft and participated in the research, design and implementation of special application cryptographic systems.

I'm really not Satoshi Nakamoto

This is also the case. When Satoshi Nakamoto started writing the Bitcoin white paper in 2008, he asked the British cryptographer Adam Back about some of his questions about Hashcash. His b-money.

Message Summary: I'm very interested in reading your paper on b-money. I'm about to publish a paper that expands your idea into a fully working system. Adam Back noticed the similarities between our two papers and introduced me to your website.

Not only b-money is a famous work
David, a sincere scientist, of course not only has the achievements mentioned above, from being quoted to using his name to name the Ethereum unit, he relies on more than b-money. Created by him Crypto++ is a free and open source C++ class library containing encryption algorithms and schemes originally written by him.
Crypto++ is a very powerful cryptographic library that provides a wealth of encryption and decryption algorithms, including passwords, message authentication codes, one-way hash functions, public key cryptosystems, key agreement schemes and deflate compression, involving RSA, MD5, DES, AES, SHA-256, etc., basically the main functions required by cryptography can be found in it, with complete functions and good uniformity, it is very popular in the field of cryptography. Currently, Crypto++ has been widely used in academia, student projects, open source and non-commercial projects, and enterprises.
It can be said that the outstanding David has contributed a lot of core theories to the development of blockchain technology, laying a solid "foundation" for future generations to continuously explore blockchain technology and in-depth research in the field of encryption.
It's no wonder that when counting outstanding contributors in the field of encryption, David is always included and ranked among the best.
