Preface Workshops Revisit: Month of Blockchain

Blockchain Technology: Hitchhiker’s Guide to Blockchain

Preface Coffee had the honour of hosting Mr. Michael Yung, Head of Digital Products and Technology at Asia Miles on the night of 21st January. An experienced figure in the world of Blockchain as a result of his impressive work on refining Asia Miles’ very own loyalty programme, Mr. Yung captivated the audience with his talk on Blockchain and its usage in cryptocurrency.

Through the workshop, Mr. Yung allowed participants to understand Blockchain by breaking its concepts down into visualizable, easy-to-follow procedures, before delving into its application in Bitcoin — the most popular cryptocurrency in the world to date. The talk gradually built on to real use cases of Blockchain, in which an eager audience was introduced to how blockchain could be implemented into numerous industries. A plethora of questions were raised, stimulating an interactive discussion and exchange of ideas that transcended beyond a common workshop.

Preface would like to take the opportunity to thank Mr. Yung for his inspiring and eye-opening talk, and will aspire to continue attracting high calibre speakers to future Preface Workshops!

Blockchain Technology 101

Blockchain 101 recorded Preface Workshop’s highest attendance in its short history, as participants from many different backgrounds gathered to learn about a technological phenomenon predicted to deliver an impact similar to that of the internet two decades ago. Fresh from his studies in Oxford’s Blockchain Course, Preface Founder and CEO Tommie Lo guided participants through intricate concepts of Blockchain, and introduced their possible use in a wide range of business scenarios through Hyperledger, a global collaborative effort facilitating blockchain technology across different industries, and backed by numerous conglomerates.

Preface Coffee is re-running this popular workshop in March 2019.

Why Do We Teach Blockchain

We have been adhering to the vision of bringing emerging knowledge to the Preface Coffee space since the first day of launch; liberalising proprietary knowledge pieces from graduate schools to a community we love, believing that there’s nothing cannot be learnt, and we then apply the knowledge to make a difference in the world.

We therefore teach Blockchain Technology as we believe in its power to become a revolutionary enterprise application. Our Blockchain workshops aim to deliver a deeper public understanding through diving into Blockchain Technology with cryptography and delving into its relationship with cryptocurrencies like Bitcoin.

Hello, Future: The Rise of Blockchain and Its Implications

Widely regarded as the greatest invention in the past century, the Internet has drastically transformed the way we live our lives, granting us access to treasures of knowledge, instant information, and unparalleled social connectivity all over the world. Ironically, given the information obtainable, it is ultimately the Internet that has also become the causation of increasing fraudulent behaviour and lack of trust among humans.

Whether you’re a coffee shop owner looking to import some high quality coffee beans, or you’re simply trying to find a nice dress on an online shop, you’re prone to the same risk of being conned. In the same way that you cannot verify whether you’re buying high quality fair trade beans before receiving them, neither will you be able to tell whether the dress you’re buying would look the same as it does on the website in its real form. The key to solving this trust and verification issue? Blockchain.

The Blockchain Solution

As a decentralised, distributed digital public ledger, Blockchain enables transactions to be recorded and linked across a high number of computers, meaning alterations to any records would also require further changes to subsequent transactions, making Blockchain theoretically unalterable. Blockchain rose to popularity as the underlying technology behind popular cryptocurrency Bitcoin, and in recent years, leading corporations like IBM, JP Morgan, Intel and the Linus Foundations have led a Hyperledger project to develop Blockchain Technology on enterprise application level.

Why the hype? Whilst Blockchain may not revolutionize every profession, there are many niche industries that can still benefit from Blockchain’s immutable system. Apart from obvious benefits to the finance industry through cryptocurrency, Blockchain can also revolutionise supply chains by flawlessly tracking goods from its supplier to point of delivery, eliminate fraudulent insurance claims or loopholes by recording and storing claims and payments, and remove the middleman in transactions by eliminating the inherent trust issues and reliance on ‘good faith’ evident in the contracts between individuals, companies or organisations. These are just some of many prime examples of how Blockchain can transform key industries.

With Blockchain, we fill a void culminated by the lack of trust built by the Internet, and complete its biggest flaw. Blockchain is technology’s great step into, and ultimately is, the future.

If you want to take a closer look at how Blockchain works and its applications in the real world, Preface Coffee is hosting Blockchain 101 workshop in which the founder of will take the audience through the brief history of Blockchain, how it works as a decentralised mechanism, and why it is one of the most important innovations in the 21st century.


編程力量 讓構想逐步實現

隨世界科技的發展,編寫程式不再是程式員的專利,它已成為學童的必修課程。學會編程,究竟可如何利用科技改善生活?從一班Preface Junior Coders 的經歷,或能給大家一點啟發。


在老師的指導及與Preface Programmer的合作下,學生逐步實踐其構想。他們在設計應用程式時除了要考慮用法、功能和使用者的需要,更要解決如何存取數據等問題,難度實在不少。小至外觀,大至功能,每一個細節皆是學生討論過後的成果。通過不斷的嘗試與解難,他們終於設計出一個令他們滿意的應用程式。為精益求精,他們反覆測試,發掘可改進的地方,務求令程式更優秀,日後供社會廣泛使用。

對於這一班學生的表現,編程導師 Queena表示:「學習編寫程式所得的不僅是親身設計的遊戲或應用程式,而是在過程中如何發揮創意,反思和解難而得的經驗。」


Preface Junior Coders 除了是程式編寫員,更是發現者和解決者。他們洞悉需要與問題,並嘗試用程式解決問題。

程式語言 2030 的官方語言



不少機構及研究以2030年作為對未來投射,預測世界發展的新趨勢。麻省理工科技評論(MIT Technology Review)報告指出,2030年時將有不少工種被人工智能或機械取代,同時也會因應技術發展衍生新的產業。人類必須具備不斷學習的能力,才能適應快速變革的新產業與新技能。該研究所研究員說:「未來像創造力、適應性和判斷力這樣的能力,比特定專長的知識,或知道如何使用釘槍的能力更重要。」



序言(Preface) 教育總監謝旭博士表示:「未來需要的人才再不是具備知識的人,而是具創造力、適應力以及懂得與電腦機械合作無間的人。這正是傳統教育之不足,未來需要的是以人工智能結合教育提供的個人化教育。」
