What is EXC?

EXC is a cost and energy efficient digital currency platform developed by Mr. Koji Fusa and Mr. Susumu Kusakabe so that payments and transactions worldwide can be conducted digitally.

EXC is comprised of 2 things:

  1. EXC Token
  2. EXC Platform

The EXC platform is a platform that Central Banks can implement so it's citizens can trade and transact the digital version of the fiat currency, whereas the EXC token (excor) is a cryptocurrency that uses EXC Platform as its trading platform. For example, if the FRB wants their USD to be used digitally they could use the EXC Platform.

To trade digital currencies using the EXC Platform, all you need is a phone that is compatible with NFC (Near Field Communication) which most smartphones brands including Apple, Huawei, Samsung, Xiaomi, Sony, Oppo (and many more!) are.

By having top-notch security level of EAL 6, super speed of 0.2 seconds per transaction, having the capacity to store value and being the first cryptocurrency to obtain a patent, many technology experts in Silicon Valley are looking forward to its potential.

Historical Background of EXC

To understand what EXC is all about, it is important to know its historical background.

During World War 2, the economist John Maynard Keynes conceptualised a supranational currency called ‘bancor’ to bring stability and global economic balance. He also planned to establish an international organisation called the 'International Clearing Union' as the institution to manage the bancor. In the Bretton Woods Conference, the British government officially announced that they would implement Keynes's plan after World War 2. However, due to America's dominance and obstruction at the time, the plan failed and the USD became the standard currency.

If Keynes Plan Was Implemented:

  • Standard Currency = Bancor
  • International Organisation = International Clearing Union

Which is Currently

  • Standard Currency = US Dollar
  • International Organisation = World Bank and IMF

Our current situation is far from what Keynes imagined and has not brought global economic balance or stability. EXC aims to bring Lord Keynes's vision to reality and is the only cryptocurrency with the required features to do so.

The founders of EXC (Mr Fusa and Mr Kusakabe)

Koji Fusa

Mr. Koji Fusa is a finance expert with experience working in investment banks including S.G Warburg, UBS and Credit Suisse. In 2004, he establishes a hedge fund call Sandringham Fund which gets awarded the 'Fund of the Year' in the same year. He is currently Oxford's special strategic advisor to the paediatrics and gets invited to lecture students about M&A, private equity, hedge fund, GFC at Harvard University, London University, Hong Kong University, California University and Columbia University.

Susumu Kusakabe

Susumu Kusakabe is an engineer who developed the NFC, FeliCa, Edy, osaifu-keitai and Q-core server during his time in SONY.

He was responsible for forming the international standard for contactless technology (which he named NFC) which is now a vital technology used around the world including Apple, Huawei, Samsung and QUALCOMM. The FeliCa is a fiat currency payment system with a security level of EAL 6. It is said to be one of the most secure payment systems and is implemented by Octopus in Hong Kong, Ez-link in Singapore and Suica in Japan. The Q-core server is a low-cost and high-performing server which is now being used for EXC.

Through the collaboration of Mr Kusakabe's technology and Mr Fusa's financial background, they aim to recreate Keynes's supranational currency that is adapted to modern society.

3 Main Characteristics of EXC

3 Major Features of EXC
  1. High security
  2. Store of Value
  3. Low Cost operation

Although there is much more to EXC, we will dig into the above 3 in this beginner's guide.

1. High Security (3 Way Data Base)

There is an international standard called the 'Evaluation Assurance Level' which tells us how strong the security is through a scale of 7 (strongest) to 1 (weakest).  FeliCa which was developed by Susumu has an EAL 6. This is equivalent to the security levels that governments have to protect their nuclear weapons from cyber attacks.

Although EXC's Security levels are being tested, it is likely that it will score EAL 6+ as it was developed by further improving FeliCa's security.

Mr Susumu also made sure that EXC is resistant to hacks from quantum computers, which out of around 1500 cryptocurrencies only around 12 have. (statistic in 2019)

Through the 3 way data base security where an AI matches the owner, coin, transaction with an ID, it ensures complete traceability (transparency) and prevents money laundering. If by any chance the crypto exchange company gets cracked and illegal transfers occur, it is possible to restore the original state by following the record, making it meaningless to even attempt cracking.

2. Store of Value

Excor adopts an independent digital central banking system, where an AI stores 50% of the highest market capital value excor reaches in USD. e.g. if the market cap of excor reaches $100 billion it will have $50 billion USD stored.

The stored money will be used when the price of excor reaches 50% of its peak market cap, ensuring that it will not fall below it. Thus allowing excor to store value.

Although excor is a floating cryptocurrency, there is no limit to its highest price whereas it will not fall below 50% of its peak price. This makes the chances for the price to increase by more than 50%. When AI traders enter the market, they will all buy excor as their algorithm bets on the side with over 50% chance of winning.

3. Low Cost Operation

As mentioned earlier, excor has an independent digital central bank system where the AI does all the work. EXC can operate with small amounts of electricity and no human intervention.

The electricity required to run one server (Q-Core-Server) to cover the transaction of 30 million people in an economic zone is just 7kw/h. The Q-Core-Server developed by Mr. Kusakabe is extremely energy and cost efficient. The transactions are completed within 0.2 seconds, meaning that people can send upto 200 million remittances per day.

This means that the electricity used to power 70 light bulbs for an hour can cover the transaction of one-third of the world's population. When transfering money across borders, it will cost less than one-tenth the fee banks require. The money will be credited to the other party in just 0.2 seconds unlike banks that require a couple days.

Patents by EXC

In addition, Mr. Fusa who is the developer has chosen to not spend money advertising and marketing excor to raise the net value of the asset as high as possible, thoroughly committed to 'preserving value'.

The above technologies are already patented in Japan AND the USA. GVEltd (the company that developed EXC) are applying for other international patents. There are no other crypto assets with 14 patents for just 3 aspects of the business.


EXC is a next-generation digital currency platform that can replace payment services around the world safely and at low cost.

The three advantages include:

  1. High Security,
  2. Store of Value
  3. Low Cost Operation.

And a total of 14 patents that warrants its value and trust.
