What is Cardano? Analyzes on four side.
History + Future + Team
Centered on the IOHK / Emurgo / Cardano Foundation, it presents “to date” and “from now on” in a concise but detailed manner and flatly (including Cardano’s past faults).
Holder + Use of funds
Check
・the percentage of ADA holders
・the use of ADA by the IOHK, Emurgo, and Cardano foundations that are held in large quantities.
Mechanism
I will challenge easy-to-understand explanation of how the Cardano project works.(but explain as close to the essence as possible.)
Term + Background
Terms such as Ouroboros, Shelley, and ADA all have meaning. Learn term while introducing actual poems!

Due to the nature of POS, it is important to look at the distribution of ADA.

Issue limit: 45 billion ADA
└70%, 31 billion: Distribution
└10% 5 billion: IOHK (2.4 billion) Emurgo (2 billion) Foundation (600 million)
└60%, 26 billion: Other
└ 30% 14 billion ADA: For staking reward

There are statements about the use of funds from IOHK and Foundation, which are held in large quantities. Emurgo is unconfirmed.
IOHK financial statement (currently unused, issue a separate statement when using funds)
Foundation statement (currently unused, use of funds is limited to the purpose stated in the Foundation certificate)

Also, the pyramid diagram on the right is the best way to see what level of ADA owner you are!
As a guide, I added the pre-sale data. Minimum is the minimum purchase amount, Midian is the amount of people in the middle of the pre-sale purchase ADA number ranking, and Average is the average number of ADA purchases. The maximum purchase amount is 780 million ADA
For example, if you have 1.5 million ADAs… the top 1% is among the top 3000, but not reach the average pre-sale purchase.


The table above is a bit complicated, so I made it simpler.
Suppose that there are 10 people with ADA transaction record computers with 10% power.
This transaction recording PC has three functions.
・ Real transaction book (Ledger)
・ Wifi communicating with other 9 people(Network)
・ A brain part that can calculate who has power and who can write in the record book (Consensus)

Cryptocurrency generally moves in the following 3 STEP.

STEP1
Person in left ask to write the ADA transaction on “Ledger”. These 10 people will share it soon by “Network”.

STEP2
The person who can record the probability of 10% each randomly is selected by the “Consensus” function. This time Tanaka was chosen as the writer!

STEP3
Mr. Tanaka confirmed that there was no problem in transaction, so he recorded the transaction in “Ledger”. If the other nine people have no problem, write it to their “Ledger”.

Now, what is the worst thing about this common cryptocurrency mechanism? If 5 members of them(50%), negotiate and do something bad, the system is over. The reason is that if a person with more than 50% of the decision-making power makes the system wrong, the system cannot be rejected. So “what is this %” Is really important.

ADA decided to respond to “% = ADA holdings”. In other words, the more ADA you have, the more you have the power to record ADA transactions. it seems a very secure system, as follows:

・ If you hold 50% or more of ADA, you will be able to do bad things, but if you do bad things with 50% power, the value of ADA will crash, and you will suffer serious damage.
・ It is designed to end up with 1,000 people with 0.1% power (see WhyCardano’s “Decentralized” pull-down).So you need to convince 500 people to attack.

Now that you understand the mechanism, I will introduce some backgrounds of terms to make Cardano more enjoyable.
Cardano
Cardano is the name of the project, but its origin is Geroramo Cardano, a 16th-century Italian mathematician (finding imaginary numbers, make mathematics academic thing ).
In addition to mathematicians, he was also a doctor, gambler, philosopher, and astrologer.
My father is a friend of Leonardo Dawinch.
He said “How to gain gambler’s greatest mathematical profit is that never do gamble”

ADA Lovelace

ADA is the main currency of the Cardano platform and Lovelace is its smallest unit, but its origin is Augusta Ada King, Countess of Lovelace, a 19th-century English mathematician and the world’s first programmer (however, there is also the theory that it is the ADA Master Babeg) and gambler,the only daughter of Byron, Shelley’s poet companion.
Although it is said to be the world’s first programmer, in fact, it seems that it is very difficult to judge because there are parts that Babege instructed. but there are also parts that ADA has devised independently and she said,
“I have a special ability that is different from everyone, I can feel more than 5 senses, and I also have excellent logical thinking and concentration. For example, if I convert music data mathematically, Can also play music from the analysis engine. “
In the days no computers or no programs, she predicted appearance of something like an iPod, it is excellent sense !!
Unfortunately, she had in that a large amount of debt by gambling, emotional instability due to depression, drugs, and death at the age of 36 due to uterine cancer.
Next, Byron, is the phase that created the cryptocurrency ADA, but it is very interesting that the only daughter of Count Byron is ADA.

Byron
Byron refers to the phase of the creation of the cryptocurrency ADA, and is derived from George Gordon Byron, a 19th-century British poet, ADA father, Shelley’s friend and political activist.
He wrote intelligencial and ironical style poems but disturbed in female relations. And its style maybe influence ADA take the path as a mathematician PC scholar who is few as women at that time.
In point of Cardano Project view, It ’s interesting that he isADA’s father, and traveling with Shelley on the way.
Let’s look at some of the remarks (poems). Some of them are famous or bit prejudiced.
・ Truth is always strange, stranger than fiction.
・ And, after all, what is a lie? ‘Tis but the truth in masquerade.
・ I love not man the less, but Nature more.
・ In her first passion, a woman loves her lover, in all the others all she loves is love.
・ Man ’s love is of man ’s life a thing apart, ‘Tis woman ’s whole existence.
・ The best prophet of the future is the past.
・ Though women are angels, yet wedlock ’s the devil.
・ Friendship may, and often does, grow into love, but love never subsides into friendship.
・ Society is now one polished horde, formed of two mighty tribes, the Bores and Bored.
・ It is easier to die for the woman one loves than to live with her.
・ All comedies are ended by a marriage.

Shelley

Shelley is the decentralized phase of Cardano, but its origin is Percy Bysshe Shelley, a 19th-century British poet, Byron’s friend,influenced by Voltaire
He had a very rebellious way of life.
・Issue “necessity of atheism”(Pamphlet of complete danger thought at that time)
・supported political activities for Irish independence.
Here are some comments (poems).
・ The sunlight claps the earth, and the moonbeams kiss the sea: what are all these kissings worth, if thou kiss not me?
・ I have drunken deep of joy,And I will taste no other wine tonight.
・Our sweetest songs are those of saddest thought.
・Soul meets soul on lovers lips.
・If winter comes, can spring be far behind?
・A poet is a nightingale who sits in darkness and sings to cheer its own solitude with sweet sounds.

.

Goguen

Goguen is a phase Smart Contract is introduced to Cardano, its origin is Joseph Amadee Goguen, a 20th century American computer mechanic, a Tibetan Buddhist.
Up to now, Cardano, ADA, Byron, Shelley and so many strange people have lined up, but Goguen contributed to academic development, including the fusion of mathematics and programming.
Formal methods and functional programming are also important axes in Cardano, and the term mathematics frequently appears in the Cardano project. (Ouroboros has mathematically proven security … etc.)
In terms of method and philosophy, it can be said that he has a lot in common with Cardano.

Basho

Basho is a phase that scalable the Cardano chain, but it originates in a 17th-century Japanese poet named Matsuo Basho.
He had traveling around Japan at a tremendous speed, it is maybe related to Cardano Chain’s scalability.
In pursuit of the ideal way of poetry, Basho continued to evolve his lifestyle and poetry. It is characterized by almost no detailed information but a deep message without using any difficult words. introduce them a little.
・古池や蛙飛びこむ水の音 (ふるいけや かはづとびこむ みずのおとfuru ike ya / kawazu tobikomu / mizu no oto) an ancient pond / a frog jumps in / the splash of water
・夏草や兵どもが夢の跡 (なつくさや つわものどもが ゆめのあとnatukusaya tuwamonodomoga yumenoato)The summer grass- It is all that’s left of ancient warriors dreams
・閑さや岩にしみ入る蝉の声 (しずかさや いわにしみいる せみのこえsizukasaya iwanisimiiru seminokoe)What stillness! / The voices of the cicadas / Penetrate the rocks.
・五月雨をあつめて早し最上川 (さみだれを あつめてはやし もがみがわsamidareya atumetehayasi mogamigawa)The summer rains, how swiftly flows Mogami River
・荒海や佐渡によこたふ天河 (あらうみや さどによこたう あまのがわ araumi ya / Sado ni yokotau / amanogawa)the rough sea / stretching out towards Sado / the Milky Way
・旅に病んで夢は枯野をかけ廻る(たびにやんでゆめはかれのをかけめぐるtabi ni yande / yume wa kareno wo / kake meguru)falling sick on a journey / my dream goes wandering / over a field of dried grass

Voltaire

Voltaire was the phase that make Cardano a permanent and evolving system, and its origin the 15th French philosopher, François-Marie Arouet. He influenced Shelley.
He is a very fierce person .
・ Written in poetry criticizing the French government ,and imprisoned.
・ After that, he became a big writer, but he suffered trouble with the nobility ,and was imprisoned.
・ Move to England and write a “philosophy letter” influenced by British freedom philosophy of Rock and Newton’s scientific philosophy ,but received critically by France and was issued a warrant for arrest.
・Bad relationship with Louis XV and the Great King of Prussia and prohibited from entering the castle.
His thought is a typical enlightenment thought that believes in human freedom and reason and fights religion and politics.
Although there are still some questions such as anti-Semitism, we have fought against vested interests until the end.
The Cardano project evolved from a cryptocurrency that had been dominated by central powers such as miners and developers in the era of Vortaire, and will be centered on ADA holders. That ’s exactly Vortaire!
He used the gambling mechanism mathematically to make $ 5 million.
・I disapprove of what you say, but I will defend to the death your right to say it.
・It is dangerous to be right when the government is wrong.
・If God did not exist, it would be necessary to invent him.
・When it is a question of money, everybody is of the same religion.

Plutus

Plutus is one of the languages ​​for SmartContract developed by Cardano, but its origin is the god of wealth in ancient Greece that appears in the comedy written by Aristopanes in 388 BC.
Because he made blinded by Zeus, we can distribute wealth without prejudice.

Marlowe

Marlowe is one of the languages ​​for SmartContract developed by Cardano, but its origin is Christopher Marlowe, a 16th-century English poet, playwright, and spy.
He is a playwright, but because he was a spy, he has a lot of mysteries in the blank periods and at the end of his life.
・Who ever loved, that loved not at first sight?
・Fools that will laugh on earth, most weep in hell.

Daedalus/Icarus

Daedalus (left) is a wallet in the Cardano chain, but its origin is a Greek mythical carpenter / inventor, the father of Icarus. Icarus (right) is Daedalus’s lightweight wallet.
He worked as an inventor and carpenter at Athens, but when a disciple invents a saw, he envies his talent and kills the disciple and is expelled.
He escapes to the island of King Minos and develops warships, theaters and labyrinths, but he and Icarus is locked in with to keep the labyrinth secret by king.
Although he try to escape by making wings, Icarus overtrusts the wings and crashes. Daedalus escapes to King Cocarus.
King Minos locates and asks King Cocarus to hand over, but King Cocarus and Daedalus will kill King Minos.

Ouroboros/Jormungandr

Ouroboros is the name of Cardano’s POS system, and its origin is an ancient symbol that represents a snake that bites its tail and turns into a ring. Jormguandr is the Rust node version, but its origin is the Scandinavian myth version of Ouroboros.
Snake is symbol of death and rebirth because it grows off its skin and withstands long-term hunger.in addition, by eating its own tail, symbolizing infiniteness and completeness. This is widely seen in Aztec, ancient China, ancient America, the Nordic (Jormguandr), ancient Egyptian civilization of 1600 BC, Hinduism and Christianity.
One of the most important and difficult things about POS is the guarantee of “randomness”.
you may think as “Is it so hard to be random? Can’t you do it with Excel?”
but there is no program that can give completely random. The question is how to raise this randomness to an astronomical level that no one can predict. In that sense, Ouroboros is a program in which the previous number drawn at random is incorporated into the generation of the next random number, and randomness creates randomness, (like eats its own tail !)
So It was named Ouroboros. The same is true for Jormguandr

Praos

Praos is an accelerated version of Ouroboros, but its origin is the ancient Greek word for Freedom, meaning mild and gentle. The implication is that you can feel free to trade.

Genesis

Genesis is a safe and fast bootstrap version of Ouroboros, but its origin is the first scripture of Christianity and Judaism, “Genesis”.

Hydra

Hydra is a speed-up version of Ourboros by parallel processing, and its origin is a Greek mythical monster that has a 9-100 neck. It has the meaning of having several heads and enabling parallel processing.

Eventually, it was overthrown by Hercules and became Aquarius.

Chronos

Chronos is a decentralized version of Ouroboros clock access, whose origin is the god of time.

Crypsinous

Crypsinous is a privacy-enhanced version of Ouroboros, whose origin is Greek and refers to people who are conscious of privacy.
