To research the impact of Brexit (Britian exits EU) today:
Areas to review given that things only happen in the next 2 years (they will sort it out):
(*): Inflation means expecting purchasing power goes down in future (low productivity & expanding money supply)
(**): Interest rate is to protect the purchasing power of money when lending (lend to protect)
What is block-chain?
Block-chain is a technology to store information with 3 key characteristics:
Why block-chain?
Borrow words from “Global Insight: Blockchain in Banking:Disruptive Threat or Tool?“. I prefer the approach of viewing Blockchain as a new database technology rather than other interpretations like peer-to-peer secured information sharing which has been applied for sending money (bitcoins).
“…Because, in fact, blockchain technology – although when you get into the technology itself, there is some complexity there and some ingeniousness – is nothing more than a new form of database … approach to database architecture, that is. Fundamentally, an improvement over the way that, traditionally, databases have been designed and used in the past.
So, what’s a database? You know, it’s a place where we store important information that we want to refer back to for various purposes, at some point in the future. Visually, you can imagine it as a cylindrical thing. It’s owned by someone, it’s administered by someone, it typically exists in a physical location. The administrator of the database is very interested in investing and ensuring that the perimeter security to that cylinder that protects the contents is strong, impenetrable. The lucky ones are the ones that know that it turned out that penetration happened, and then there’s the rest of us who just don’t know yet. And, typically, the information that’s kept in databases is raw information, not encrypted, not further protected other than the perimeter security which, increasingly proves to be penetrable. So when someone gets in there, that isn’t authorised to do that, the consequences can be dire, whether it’s the theft of someone’s identity for theft of funds or what have you, you read about this every day. So that’s traditional database architecture, and pretty much everybody keeps databases because they have important information about their activity, their client’s activity, that they need to keep a record of, and as a matter of fulfilling their fiduciary responsibilities, they need to keep that record.
Interaction between entities who keep their own separate databases requires a process of taking information from that database, sending it off to another party, for whatever the relevant purpose is, independently validating, verifying and then, of course, when the two sets of information aren’t consistent, reconciling the reasons for the differences. And, simply put, that reconciliation process between different renditions of the same data that needs to be communicated between parties accounts for tens of billions of dollars of cost every year, in the financial manufacturing process.
So that’s the way things have traditionally worked in financial database architecture for years, and along comes a new technology, this is blockchain technology or distributed ledger technology, which makes a few fundamental changes to what I just described. The first thing is that instead of this cylinder in one place, you have a network with multiple nodes, and you have a technology which enables the multiple nodes in that network to be accessed by those with a need and right to know it, and for ensuring that the data, the important information that we’re all referring back to, can be kept in sync and replicated continuously, on a real-time, or as near as need to real-time basis, between parties.
And protecting all of this is the fact that the data itself is encrypted, and the identity of the users or those who have the right, need and right, to access that information, is subject to a sophisticated identity management regime involving, again, cryptographic tools, so that it is very possible to independently verify whether or not an actor is who they say they are and has the right to access that information. And, simply put, what that allows you to do, for the first time, is responsibly share, mutualise, common infrastructure and use this database environment as a place to keep a record of important transactional information that is one record, a golden or prime record, that can be shared by multiple, independent entities, that is protected through cryptography, so that only those with a need and right to know, only the piece of information in that environment that they have the need and right to know, can do that.”
How Blockchain works?
There is so much “noises” around the topic of “explaining” how Blockchain works and I’m still in the process of distilling the information. I will start with the view of distributed database and then discuss on the applications around bitcoins, payments in existing currency, trade confirmations, reconciliation in general to some fancier concepts like clearing, “smart contract“(*/**). A bit ambitious I guess…
What I often forget?
In a cryptocurrency system, miners are incentivized to create blocks to collect two types of rewards: a pre-defined per-block award, and fees offered within the transactions themselves, payable to any miner who successfully confirms the transaction. (Wikipedia)
Video references:
Bitcoin: Transaction block chains: The mechanics of a bitcoin transaction block chain, which is a construct that is generated by bitcoin miners and functions as a global ledger for recording and validating bitcoins.

Objective: to gather thoughts around the topic which I found interesting given the volatile market recently. Not about making money though.
19-Dec-2015
First, start with why I’m interested in the topic: bitcoin, crypto-currency & blockchain. Many talk about it but I have no idea what they are. Shame on me :(.
Video to watch:
Notes: Money represents trust and facilitate exchanges. Money is recorded by ledger. Ledger makes public – thanks to Blockchain technology. Currency recorded in blockchain public ledger is bitcoin.
Questions: How to get/mining bitcoin? How to determine fair-value of bitcoin?
Notes:very simplified introduction. for viewer’s curiosity only
Notes: not finish watching yet… To be updated.
On recent news, interest rate for USD deposit in Vietnam drops to 0. So what?
26-Dec-2015
I keep on thinking about the value of money/currency. How much is a dollar worth of? And under which perspective?
Anyway, came across this series in Youtube. Seem interesting…
28-Dec-2015
It occurs to me that the previous series might relate to the following one. Thinking about the bridge of all these jargons: money, currency, purchasing power or store of value, gold/silver, and credits.
24-Jan-2016
It is very interesting watching the two videos and I am certain to recommend those to anyone. In fact, I spent three first days of 2016 to complete the series.
At the end, probably it changes my view of:
1) currency/money as representation of purchasing power,
2) how we should focus on protect and increase purchasing power more than money as numbers,
3) view of credit / debts as good or bad factor of the economy. Credit causes inflation (partially). Increasing productivity stabilizes inflation. Two forces cause cycles in a good & healthy economic growth.
With that, I somehow have better faith in Bitcoin giving how it fits as a good (non-fiat) currency. Anyway, next questions probably are on the exchange of currencies and where are the gold now?

13 for 13 – Excellent Rules to Live by (Plagiarized from Duncan Neideraur)
1) Have a plan, but not one that is over-engineered. Opportunities will inevitably come your way, and you want to be poised to consider them.
2) Every boss is a role model from whom you can learn. Some will be role models you’d do well to emulate, and others…not so much. Either way, you can learn a lot from them about what to do or what not to do.
3) The road less traveled is more interesting, so take it once in a while. It will give you the courage to stand behind your convictions.
4) Remember that most of the advice you will get is conventional wisdom, which is synonymous with playing it safe. Follow your heart, not someone else’s mind.
5) Bring passion and energy to what you do every day. If you find things you enjoy, this won’t be a challenge.
6) Success is highly correlated with one’s self-awareness quotient. Play to your strengths, and understand your shortcomings.
7) Keep your friends and family close and consider them your personal board of directors. They will be your compass and your foundation.
8) Show up prepared…for every encounter.
9) Stay on the high road – it isn’t very crowded, but it should be!
10) Treat everyone with respect and kindness, not based on what they can do for you.
11) Be an optimist. As the saying goes, a pessimist sees the challenges in every opportunity, while an optimist sees the opportunities in every challenge.
12) Expect more of yourself and those around you.
13) Leave every situation better than you found it. Find your own way to pay it forward.
Firstly, I’m blogging from iPad. Yup, can’t resist a pad. Hehe! Buying app Blogsy for blogging seems not a bad decision, it serves me well.
In the past four months, many things happens. I’m much busier at the new workplace and the new job. Big gap to the time in NTU. There are times of doubts but overall, work is good.
I’m officially entitled to Dr. Le now. Yay! Encountered questions like “what will you do next?” or “you’ve got your dream, what’s next?” – let’s just say: we have climbed a mountain, and we will climb another mountain. For now.
My big family has just visited. Were quite nervous for 8 members to stay in a small house. It went fine. But reminder of much to be achieved. And a reminder of ages, of nothing that last forever.
SYTYCD is still a best show to me. Glad to saw a dance that make me nearly cry. Glad to know that side remains.
That’s all. Hope for good updates in months to come… Cheers!
