LINK, The Beginning

January 2009, the Inception of BITCOIN

In October 2008, when the global financial crisis fired from American Subprime Mortgage Crisis were spreading in the air, a short 9-page article was published right after a website has been made. The title of the paper said “Bitcoin: A Peer-to-Peer Electronic Cash System.” Cryptologists and developers went wild to the idea and possibility of the currency transfer that could be done without mediation from financial institutions. On January 3rd 2009, the world’s first cryptocurrency ‘Bitcoin’ brought by voluntary engagements of developers came into the world for the first time in history.

The inception of Bitcoin opened a new phase of cryptocurrency and new ecosystems derived from cryptocurrencies. As The Dutch East India Company has opened the door for the stock corporations, stock exchanges emerged and lead the renaissance of stock corporations. And then today’s stock corporation systems has been formed in market economy organization-centric way. Very similarly, around a year later, the cryptocurrency ecosystem initiated from Bitcoin accelerates its growth pace from February 2010, when cryptocurrencies started to be traded in markets just like the stocks in stock market at bitcoinmarket.

Following after the Bitcoin that has served much of currency’s features such as store of value and means of exchange, Ethereum emerges in July 2015, and improves the cryptocurrency into the next level. The concept of smart contract dramatically improved the functionality of cryptocurrencies, and it became a lot easier to develop Ethereum based ERC-20 tokens, which allowed the Initial Coin Offering (ICO), much-like the IPO stock market, to be activated from 2016.

And then the hyperextension of ICO market emerged. In early 2018, the Telegram messenger has raised 1.8 billion in funds; and with its unique ICO funding style, EOS raised over 4 billion dollars from its ICO sale.

LINK, September 2018

LINE Messenger first rolled out with its motto “CLOSING THE DISTANCE” in June 2011, and it rapidly grew into a service platform that has over 166 million MAU in 4 key markets (as of end of June, 2020) by closing the gap between people, information, and services. We can’t appreciate enough on how much support and contributions from hundreds and millions of users took to accomplish LINE’s fundamental growths.

LINE has been deliberating in how to give back for the user contributions since late 2017. For that, we’ve also been following trends in blockchain and token economy. We kept these questions in our mind — how can we reward our users with blockchain and tokens? How can we better develop LINE with them? The answer to those questions came to a conclusion to LINE’s general-purpose cryptocurrency, “LINK.”

LINE prepared the entry to blockchain market in steps. On December 2017, we built a blockchain product development organization ‘Blockchain Lab’ within LINE Plus, the token economy business organization ‘unblock’ in April 2018, and then blockchain mainnet development organization ‘unchain’ in the following May. Soon after founding these three organizations, and because the product, service, business, development sectors could organically and agilely work together, we could quickly launch LINK’s mainnet ‘LINE Blockchain’ and create its first ‘Genesis Block’ on August 23rd, 2018. And we could never forget how thrilled we were when we first engraved the following phrase onto the genesis block:


Following after that phrase on Genesis Block, we also wrote down the names of over 300 people who made contributions to the launch of LINK. Roughly after 10 days, on September 4th, LINK started to be distributed to public via LINE’s own exchange BITBOX(currently BITFRONT).

The user reward, and the experiment with NO ICO

LINK is LINE’s single cryptocurrency used as rewards to acknowledge user contributions.

Though it is devised to encourage participation to ecosystem by allocating wallets to mass users instead of small set of investors, a plan to issue token in a large scale with no ICO was still was a challenge even back by then.

But since we witnessed the advent of corporations that grew from user contributions, and blockchain-based rewards, we were very convinced with this newly rising perspective in users: the service users are less likely to be deemed as mere ‘users’ who appreciate the services for free, but rather as ‘contributors’ who show contributions and engage in the service growths. Though we were more than convinced by this idea, we had both anticipations and anxiety for the outcome to come since our experiment was very challenging.

LINK kicked off with $4 range when it first was listed at BITBOX Exchange in October 16th, 2018. But it also bottomed to $1 range during the crypto market slump in late 2018 and we were about to fret about the market situations. However, from the early 2019, when the crypto market was yet to get recovered, LINK price started to recover against Bitcoin’s price volatility, and then it started to go above $3 in February of 2019 and it is currently swinging around $20 range.

The idea and purpose to distribute coins as user rewards are great. But at the same time, it requires much efforts to form the value when LINK is being distributed to users, not the industry investors from the start. It’s because even the issuers of LINK cannot control coins that’s already been listed in the market, and we can only rely on the market demands and expectations at the beginning phase of the ecosystem. In this respect, the current price of LINK has proven that our experiment and hypothesis were not false.

Well, but there are 5 million LINK circulating. It’s somewhat embarrassing to admit that the current market capitalization of LINK is around 113million dollars (as of August 4, 2020). We certainly did not build LINK to see such size and impacts.

Finally, purchasing LINK in Japan, one of LINE’s most influential market, was allowed and we will not stop putting our best efforts to make LINE Token Economy complete.

What defines the ‘Popular’ dApp Service?

There was an interesting bet started from the Consensus 2019 held in New York. The very front runner of decentralization and Bitcoin’s core developer Jimmy Song, and the co-founder of Ethereum Joseph Lubin had a head-on collision for whether dApps can settle into regular people’s lives. This $500K bet has the following terms designed to verify dApp’s success in future. (

  • Due: after 4 years (May 23rd, 2023)
  • Criteria: The DAU (Daily Active Users) and MAU (Monthly Active Users) of Ethereum Blockchain
  • Conditions: Joseph Lubin wins when more than 15 dApps achieve over 10K DAU or 100K MAU; Jimmy Song wins in the opposite case — if there are less than 15 dApps achieving those conditions after 4 years.

How does that sound to you? The 10K DAU and 100K MAU can look like a joke when they’re applied into mobile services. Since the numbers even indicate the prospective results in 4 years, it can look even more depressing when we think about the realistic mass adoption of blockchain-based services.

Ironically, the bet only challenged us to beat the odds. Those numbers are quite reasonable considering the limitations of Ethereum the public blockchain, and the absence of preexisting mass users base as well. Right?

Well, we already had 165million MAU in mind when we were building LINK? And we have built our own mainnet already? And we have decent LINK dApps available in the market because the developers and planners could build them? Let’s face it and correct me if I’m wrong. Is there any other global service providers in the world that has insights in their main targeting market (in case of LINE, it’d be Japan, Thailand, Taiwan, and so on).

Transactions, and Wallets

What will be the most correlated and meaningful variable that can affect the value of a cryptocurrency project? After the long research on cryptocurrency ecosystem, we concluded that the variables are transactions and wallets. The market capitalization (the total value of cryptocurrency ecosystem) is formed according to the network activation. And for the network activation, the number of transactions and users of wallets are the direct variables.

Based on the calculation on the three major platform coins (ETH, EOS, NEO), the ecosystem value is formed at 33.5 times of the daily transactions. And the value of one active wallet is estimated at $76.7. That is, in order to raise the platform’s ecosystem value, it takes more people to hold cryptocurrency in wallets and generate transactions.

Kakao corp, the Korea-based messenger corporation has announced that wallets in its messenger will make remittances easy. Also Facebook founded Libra Networks in Switzerland and planning to launch the stable coin project.

Sidenotes: Facebook is also servicing WhatsApp and Facebook Messenger.

It’s clear that combining daily-used messengers and cryptocurrency wallets, and user-prioritized UI/UX can advance the cryptocurrencies’ mass adoption.

Yet, the number of the wallets in major platform coins still stays small. For Bitcoin it’s 66 million, Ethereum 28 million, and 7 million for EOS. It shows that the size of cryptocurrency market is still small, and has a lot of room for popularization.

Currency, and the Influence

As of April 2020, there are 196 countries in the world. Out of those countries, a total of 180 currencies are in circulation. Excluding the pegged-currencies like Dollars or Yuans, there are 130 currencies that has its own exchange rate. Yet we are not much aware of currencies other than Dollar, Euro, Yuan, Yen, or else.

How about the cryptocurrency market? There are 5,429 coins listed at Coinmarketcap as of the late April 2020. There have been too many coins generated compared to the market size and usages. Most cryptocurrencies are predicted to fade out into history and only the small set of main cryptocurrencies will remain, looking just like the fiat market. If many, there are likely to be 130 cryptocurrencies eventually remaining in the market just like what current fiat market has.

And how about the awareness and impact of cryptocurrencies? Surely Bitcoin and Ethereum has more awareness and impact than the fiat currencies from lesser-known countries. The market cap of Bitcoin is $165B (as of May 6, 2020), and it is nearly at the same level as the 2019 GDP of Hungary($170B) and Ukraine($150B), ranked at around 50th in the world.

At the same time, currencies used within the economically and conditionally unstable regions like Argentina, Venezuela, Iran are not fulfilling the features as currency due to the high inflations. In such cases, cryptocurrencies — most commonly represented as Bitcoin — could replace the role of current domestic fiat currencies to perform as stable currencies.

Let’s look at how frequently currencies are being used. How many people are actually using currencies excluding the ones with the highest demands (Dollar, Euro, Yen, Yuan)? That is, how many DAU (Daily Active Users) that those other currencies have? This cunning (?) question started from Hanju Lee, the CEO at a global cloud service corporation Bespin Global.

The concept of DAU actually should be familiar to people engaged in mobile/Internet services. And the DAU of fiat currencies in Korea and Japan can be estimated as the population of each country: 126 million in Japan, and 51 millions in Korea. The estimate covers all age ranges from infants to seniors. And what is the latest available information on Facebook’s DAU? As of April 2020, it is roughly 1.7 billion.

Let me ask, how much of currencies are being held by people today? Before we take a look, we need to get familiar with the term ‘Reserve Base (or Monetary Base).’ The reserve base is defined as “the sum of the eligible balance sheet items (in particular liabilities) that constitute the basis for calculating the reserve requirement of a credit institution.”

Based on the average balance measured at December 2018, the reserve base of Japan is leveled at $4552B, and Korea $178B. If those numbers are divided by population of each country, the per-capita are $36,126 in Japan, and $3,490 in Korea. Considering the economically active population, the practical holding amount can be doubled as well.

Facebook has announced that it will issue its own stablecoin “Libra.” If Facebook’s plan is successfully carried out against all the regulatory odds, the monthly average holdings of Libra can be calculated as $614B, which accounts for 13.4% of Japan’s reserve base. Besides, Facebook users are scattered at dozens of countries, which can also enable international transactions. Libra may have more stability compared to national currencies from countries suffering from a large financial loss or unstable international/domestic situations.

The vertical integration of cryptoasset, platform, exchange, and the users

LINE own-developed its cryptoasset LINK and the mainnet that runs LINK, along with a wallet and development tools that can store/transfer/issue/manage cryptoassets and crypto exchanges that allow cryptoasset trading. To a certain extent, LINE is a one-of-a-kind blockchain provider of a highly integrated and user-friendly platform that has the entire range of ‘Value Chain’ of blockchain. Also, LINE’s rich user base can fuel the mass adoption (also represented as our slogan ‘Blockchain, Designed for Everyone’) as well.

Not to mention, LINE is at its best regulation friendly in terms of following FATF rules and guidelines of designated countries, and operating crypto businesses under the regulatory system. Securing the long-prepared brokerage license in Japan and LINK whitelisted in Japan that required a strict screening process are some of the examples.

Soon to introduce cryptoasset designed as easy as a daily messenger in Japan, LINE will implement LINK onto family services for user rewards, and then extend the implementation range to the external services over time.

The popularization of blockchain hardly seems to be a reachable goal. It can be as time exhausting as the last three years that took LINK to get its Japanese license approval. That time is still worthwhile since we understand that blockchain popularization cannot establish without a solid foundation in the first place. Since our ‘Steady yet not-so-slow’ pace can move finish line to blockchain popularization closer, there is no stopping until the end.

Forward to LINK 2.0, after LINK 1.0

20 months has passed after LINE launched its general-purpose cryptocurrency with a motto of ‘THE BEGINNING: LINE TOKEN ECONOMY.’ We’ve been racing as if there is no speed limit: we’ve been preparing, developing, and grew out of the devastating crypto slump and only became stronger.

We’ve been sticking to the plans we stated on our whitepaper as well — we’ve completed the launch of dApp services upon the mainnet open, and development of LINEAR Network that is capable of interchain.

We also proved that our experiment was not reckless with the issued 5 million LINK and the price it has formed thus far. And we decided to forget about the ‘experiment’ for a while and instead immerse ourselves into ‘exploration,’ so we can go further with our faiths and pave our own way to a bigger world.

I’d like to finish my article by quoting the phrase that’ll permanently stay in the block of Daphne Chain.
