#NFTsummer A few weeks ago, we interviewed Xixi Huang (AW#17) in Mandarin and as the AppWorks Fellow who helps us out on the blockchain side, Xixi has a lot of ideas that are worth sharing to a bigger audience. Here's his interview in English:
西西 (Xixi) 黃士晉 is an AppWorks #17 alumni and co-founder of Rydeit. His mission is to bring the applications of blockchain to everyday life because he believes that blockchain can make the world a more fair and better place. As an AppWorks Fellow, he is responsible for guiding founders to think about blockchain and providing insights on blockchain-related investment deals. Before AppWorks, he led his previous team to build more than 10 dapps, including famous games in Taiwan such as 柚子打魚 and Shrimp.Finance. Within a month of launching these games, they had amassed over NT$ 100M (~US$ 3.5M) in transactions. His favorite pastime is traveling with his grandma, and his ultimate goal is to persuade her to buy Bitcoin!
Check out what Xixi has to say about blockchain and NFTs.
#NFTevolution
I started to learn how to write smart contracts in 2016, and learned the entire logic of ERC-20 for tokens and ERC-721 for NFTs. While I was learning about NFTs, I realized that the combination of NFTs with video games was very fitting. In video games, the treasure and equipment you collect becomes virtual assets as NFTs. And the process of using smart contracts to exchange items was very efficient on the blockchain.
At the end of 2018, I designed and created a zombie video game, integrating the concept of playing and drawing cards and packs. Within a pack were 3 NFTs with zombies on them. As a player, the more cards with zombies you collect, the higher your score, and the more tokens you can ultimately earn. From this game, I got connected to other game manufacturers and publishers who were also interested in creating virtual game assets through NFTs. We all had the same idea -- NFTs can bring more meaning and value to the players.
However at the time, many people in the market still believed that tokens and games were riddled with fraud. Since the lifecycle of video games can be short, many traditional gaming companies in the end didn’t find it worthwhile to learn how to integrate NFTs or blockchain into their games.
While the nature of NFTs hasn’t changed, the market has evolved. People’s curiosities are growing, more applications are being developed, and more creators are cropping up. I think now is the right time to start talking to companies about how to integrate NFTs or blockchain into their businesses or games.
#NFTplayground
I think there are many opportunities to start a business these days, and people who want to start one should think about coming to blockchain. Not only is there a huge opportunity but the possibilities are endless. And within blockchain, NFTs currently offer the biggest opportunity. However, it can also pose a new challenge to the team’s endurance, because while easy to obtain traction and users with NFTs, the challenge lies in retaining them.
Similar to other blockchain applications in the past few years, when a new concept is invented, it’ll be flushed with many early users. However, because the surrounding infrastructure wasn’t in place, it was difficult for founders to make valuable extensions or applications. And many of these users don’t actually care about these blockchain products and they are only trying to leverage the ecosystem to make a quick buck. Once they earn all that they can, they will move on to another project.
Right now working on NFTs, you can collect a lot of data in a short amount of time and also make some income to keep you afloat. Founders should seize this opportunity to understand these users, then modify and optimize both their products and mentality to retain them.
Since there’s no geographical restriction on blockchain, I would encourage founders to look beyond your country and region in expanding your NFT products. Also, since blockchain is closely related to finance, if you don’t have a good pricing strategy (or token economics) for your NFT products, the prices might fluctuate greatly. You need to be prepared and remind your users of the risks, otherwise you’ll ultimately get scolded!!
#NFTera
This year, I finally consider myself an official NFT collector. I pay special attention to NFTs with contemporary significance, such as Hashmasks. It signals to the public that NFTs are not just for collecting but that game mechanics can also be applied to interact with users. If we look back ten years from now I’m confident to say that the project that really brought the NFT wave in 2021 would be Hashmasks.
In addition to veteran projects like Hashmasks, other collections I care a lot about are related to Metaverse, such as The Sandbox. I believe that the world will become more and more decentralized and virtual. It is very likely that the next generation will be immersed in a virtual world like Ready Player One, so I am also very optimistic about NFTs in digital worlds like The Sandbox.
The possibilities are endless when it comes to NFTs. Right now, few NFTs are connected with our daily lives. For example, I bought a Hashmask. If I want to show it in my apartment, I might still need to print it out. In the future, how will we connect NFTs to the physical world? I believe they can be applied in many ways, including frames, wallets, cars, house deeds, leases, etc. These products in daily life can be combined with NFTs. We just haven’t opened our imagination yet. It’s hard to imagine that only 20 years ago we were having a hard time believing in the power of the internet.
The development of science and technology not only relies on infrastructure, but also the user's learning curve. The world needs to talk about blockchain more, so that everyone will gradually become familiar with it and it’ll continue to evolve.
If you're a founder working in blockchain or NFTs, welcome to apply to AppWorks >> https://bit.ly/3w0WyIl

量子計算對新一代物流管理的衝擊
文章來源:文/編輯部特約撰稿人

量子計算(Quantum Computing)是最早的理論基礎源自1969年,1980年代還處於理論探索的時代,2011年加拿大D-Wave公司推出全球第一套號稱商用量子電腦,但是到目前為止,世界各國所提出的量子電腦嚴格來說都只能做特定的計算,離真正的泛用型商業化(例如如預測氣候變遷、藥物最佳成分組合、材料配方最佳組合…等)仍有一段距離,不過猶如當年萊特兄弟首次飛行12秒,開創了人類商用飛行的序幕;量子計算再過幾年將會有更成熟的技術,對於物流界而言,量子計算應用於日益複雜的物流系統是可期待的。
關於量子計算的相關概念,目前已有許多其他文章有專文介紹,本篇不會再贅述這些基礎知識。對我們而言,我們可以這麼理解:假設有一台新的電腦,其運算速度是目前電腦的幾百萬倍,物流業可用這樣的電腦資源做那些改善?
演算法與資料傳輸的重要性
量子計算打開了物流中心與供應鏈系統「最佳化」的一扇窗,但是要能有效利用量子計算,關鍵還是相關數據的即時回報,以及演算法的設計。
物流的實務應用中,最著名的就是旅行推銷員(Traveling Salesman Problem)問題,也就是一個城市假設共有n個點需要去取件,從物流中心出發,我們希望每個點都只拜訪一次,最後再返回物流中心,要怎麼走可使總路徑最短。
假設拜訪點共有25個,就會有25X24X23…X2X1=25!(第一個點有25個選擇、第二個點有24個選擇…依此類推),這個值大概是「1.55X1025」。要在這麼多排列組合中找到最佳路線,假設電腦每一秒可計算「1013」個路線(每秒計算一兆次,已經是超級電腦等級),也需要「1.55X1012」秒,而一年有 3.1536X107秒,大約需要「5X104」年才能算完,就算是祖孫三代都不停歇,也無法完成此計算。
然而實務上的問題不光是如此:每台貨運車輛在都會間的最後一哩配送,每天至少都是20~40個點,而且以往 我們的運具種類少,因此在做路線最佳化時,大概只需考慮最佳路線這件事;現在(甚至以後),貨運運具種類越來越多,除了無人機、無人車,還有人類駕駛員的電動小車、甚至派送員騎的機車、自行車。
也就是說,如果有n個物流配送點,每個配送點可選擇m種運具,光是運具的排列組合就有「m x m x m .…= m2」種,再考慮最佳的路線求總運輸成本最低,而且這個計算尚未考量各運具所在道路的車流狀況,有時候算出的最短路徑說不定剛好就是塞車的路徑。
在演算法設計上,就好像要計算1+2+3…100的累加,我們可以很直覺利用一個100次的循環,每次把數字依序加入,最後得到結果;也可以利用「(100(100+1))/2」這個公式直接算出來;要計算哪條路徑最短,我們可以使用暴力破解(brute force)方式,先窮舉所有可能的路徑,逐一計算其運輸成本,全部算完後再決定最佳路徑,也可透過啟發式演算法,找到「近似最佳」的路徑。
演算法好壞有著天壤之別,如果使用較差的演算法,或許透過量子電腦可算出最佳解,但是需要耗用較多時間,這些計算時間都代表成本,如果要花很多錢計算去找出最佳解,反而減損了最佳解所帶來的實際效益,因此好的演算法才是最佳化的硬道理。
而在資料的即時回報上,這也是量子計算過程中需要管理者多關注的議題,因為屆時「計算力」已不是問題,問題是我們是否即時餵給中央系統正確的資料!
例如物流中心目前正在路上的各種運具,每分鐘需回報一次自己所在位置與狀態(包括車輛剩餘的油量、電量、目前載重),以及系統對於目前各運具所在位置與道路擁擠狀況,因此這些車輛上必須有相關的IOT設備,將訊息自動回報給物流中心後,物流中心彙整再批次送上雲端交給量子電腦計算。
可想見,我們所謂的即時,最多只能以「一分鐘」為單位,因為如果上傳的是五分鐘、十分鐘前的數據給中央系統,算出來也是五分鐘、十分鐘以前「應該」的最佳化狀態,拿五分鐘前的最佳化狀態指令作為物流資源的調度,恐怕會拉大實際運作的差距。
就拿「十分鐘」來說,十分鐘對一個物流系統而言,已經有很多事又變化,例如原本客人的訂單可能被取消、更改配送地點、緊急訂單加入、或是又有100個新的消費者下單…,而量子計算對於這類多變的動態環境,有機會把「物流最佳化」這件事真的做出來。先決條件就是,是否真的有即時把資料餵給系統。

Yesterday I was invited to co host a mandarin talk show on local tv. as usual I still had the jitters and butterflies in my tummy.
I was paired with an experienced host and interviewed 2 malay ladies, a prominent news anchor and the secretary to the Malaysian embassy in Beijing who both speaks mandarin eloquently. I had nightmares the nite before, what if they all realised my mandarin is not as good as what people made it out to be ( Alhamdullilah , HE was kind and the show went well)
but 1 thing that stuck to me was when both host and guest said they watched my shows “growing up”.( I’m actually getting used to that) .. and the host for the show called me “前辈” senior or elder ..
I was not offended nor was I taken a back. But it got me emotional and a wave of gratitude hit me hard. HE has been merciful towards me, Time has been gracious with me, You have been extremely kind to me.
I lay in bed thinking how lucky I am still out there . Traveling , exploring, creating, gathering stories to tell.. pushing my boundaries. Achieving goals .. never would I imagine holding 2 global titles “GoPro Ambassador” & “PADI Ambassadiver” . Never have I imagined making a living from doing the things that I love doing.. never had I imagined being loved by You.
I always believed Age is just a number and wrinkles does not bring with it maturity. I am 40, as long as HE wills I will continue to explore, gather and insyallah create..
thank you for all the birthday wishes and love sent my way. You might not even read this .. but It’s my 40th & this “前辈” is declaring a 1 year birthday celebration !!

?? Greetings from Hanoi, Vietnam. This is my first vlog from quarantine. As you guys may know, Vietnam is going through its 4th covid wave, and this one is quite serious in comparison to the others. Lockdowns are in place, and I don't feel comfortable meeting people and traveling at the moment. Nor is it smart or safe. As such, I'm trying to find other ways to make videos, and also use this time to improve on my own skills. One skill I really want to improve is cooking. I don't know how to cook well, despite having lived on my own for nearly 7 years. I want to use this time to learn how to cook.
It might seem strange, but I thought a great way to start to learn to cook would be with something super simple, like instant noodles. Instant noodles are the thing you make when you don't want to cook. They're literally just soup with salt and water and wheat noodles. But the physicist in me says, to be a good cook means taking something, simple ingredients and knowing how to make it amazing, based on cooking principles. As such, I want to start off this cooking series with instant noodles, and see how far I can take it.
In this video me and my chef buddy @Trái tim chàng trai Nhật【KiKi.Jp】 review a famous Vietnamese instant noodle named "Mì Hảo Hảo", as I try to plan out my method of attack for turning instant noodles into something great. Join me. This is quarantine content, haha.
