What do I need to play CryptoCorals?

All you need to play is a computer or a mobile phone and internet connexion. We recommend you to use Chrome to guarantee optimal utilization!

What is a CryptoCoral?

A CryptoCoral is a cute and unique virtual coral. Most of the time they have bright colors, complex shapes and funny faces! When you buy a CryptoCoral, it funds the plantation of a real coral in the real world. This way the CryptoCoral embodies the impact you have on reefs restoration. Once you buy a first CryptoCoral you can play with it in the game!

How much does it cost...and why?

Your first CryptoCoral costs 10,60€ (12$).
Here are the reasons why:

    - 50% goes to the plantation of a real coral

    Planting a coral is a complex process (see the different steps here) and depending on the technique used, the location of the site, the cost of the labor and the equipment needed, the costs of plantation can vary between 5 to 90€/coral! Today researcher are working on new techniques of plantation that would cost less in order to scale up reefs restoration.

    - 30% goes to the development of the game

    We want to create a new experience of giving. Where giving is fun, transparent and impactful. For the fun side we created a complete game with its own universe. A whole team of game designers, developpers, illustrator...are working on it.

    - 20% goes to our operation costs

    We want to build a for profit company to show that social businesses can play an important role in the economy. We called operation costs, the costs needed to run the company (our offices, pay the rest of our employees...).

Once you have bought at least 1 CryptoCoral, you can access the game and get an unlimited number of newborn CryptoCorals without having to pay!
NB: if you want to have more impact on coral reefs restoration you can of course buy more than 1 CryptoCoral. Each one will finance a new real coral :)

What can I win by playing CryptoCorals?
You can win prizes if you manage to reach the top in the game. We introduced some leaderboards, and every quarter the top players of each leaderboard will win some prizes, get ready :)
Why are you called CryptoCorals?
Intrigued by our name?
It comes from our vision: to offer a 100% transparent donation using blockchain technology.
If donations were made using cryptocurrencies (currencies backed by the blockchain technology) we could track the entire transfer of money from the donator and see exactly what it is used for.
We already implemented the first steps of this vision, but we need cryptocurrencies to have a better adoption rate to use them for the payment and be able to achieve our vision.
How can I get sure that my payment supports coral restoration?

Each time you buy a CryptoCoral you fund the plantation of a real coral on a reef.
Once the outplant is done, you will get a plantation certificate from the NGO by email. You will also get photos, videos of the restored reef.

What is blockchain technology, how do you use it?

A blockchain is like a public book of transactions.
The data comprised in it can not be changed, transfered or altered. It is publically auditable by everybody.
We use it as a proof of declaration: for each gen0 CryptoCoral bought, we create a cryptocoral on the blockchain Ethereum. This way, the number of cryptocorals sold as well as the number of corals planted through CryptoCoral is publicly accessible by everybody.

Why not giving directly to the NGO's working on the field?

We rethink the classic way of giving to NGO by:

    1. Offering a fun and rewarding way to act for an environnemental cause, through gaming.
    2. Being fully transparent about the impact of every user.
    3. Presenting a variety of corals plantation projects (in different locations with various species...).
    4. Collecting field data (feedbacks, photos and videos of the outplanted corals) and keeping users updated through it.

How do I get some news from the planted corals?

By email. You will get a complete report of the state of the restored reef each quarter. We will also send you photos and videos collected from the field.

How do you partner with NGO's?

We select the plantation's projects we are working with. We check different things: the level of expertise regarding corals outplant, the technology used for coral restoration (maturity, potential to scale), the cost structure (some technologies are still not mature and cost a lot per coral) and eventually the impact it can have on the future of reefs. We spend a lot of time with our partner to learn to know them :)

What is a coral?

Have you ever wondered whether a coral is a rock, a plant, or an animal? In a sense they are all three! Corals are actually little animals called polyps, living in colonies. Inside the tissue of each polyps live a kind of algae, called zooxanthellae. These algae use sunlight to photosynthesize and feed the polyps. At night polyps secret limestone which gives their rocky structure, called a reef…!

Why are they in danger?

Ocean warming, acidification and destructive fishing have already destroyed 50% of the worldwide coral population over the last 30 years. Due to raising water temperature, there are more and more bleaching events: corals are under stress and expel their living algae, thereby losing their colors and food suppliers. They then turn to white skeletons and face death.
The situation is alarming, and highlights the poor health of our oceans. If coral reefs disappear other marine realms will follow.The Reefs at Risk study reveals that unless action is taken now, 90% of all reefs will be threatened by 2030, and all of Earth’s coral reefs could be completely gone by 2050.

Why do we need to save them?

Corals are not only beautiful: as an ecosystem, they nurture more than 25% of the world’s marine species. Clown fishes, gobies, foureye butterflyfishes and thousands of other species depend on corals for nutrients, but also for shelter and habitat.
Oceans produce half of the world’s oxygen and absorb about 40% of manmade carbon dioxyde and coral reefs indirectly produce a large amount of the oxygen we breathe: the Great Barrier Reef emits as much oxygen as the Amazon , and its wildlife is as diversified!
If corals disappear, a whole ecosystem would collapse with them: entire species (known and still unknown ones) would die. And of course it would impact us, humans.
This is something we overlook: more than 850 million humans depend on coral reefs. Large communities rely on the fisheries for their livelihoods and to feed their families. Corals attract millions of tourists, divers and snorkelers. Corals even generate the beautiful white sand that is a must-have for many travelers. Because of their impact on tourism, corals support local populations.
Coral Reefs even save humans lives, as they offer natural coastal protection against storms or hurricanes. They are also a source for new medicinal remedies to treat cancer, human bacterial infections, Alzheimer’s disease, heart disease, and viruses.

How do they reproduce ?

Corals can reproduce both sexually..and asexually! In some areas, mass synchronized coral spawning events occur one specific night per year.
The timing of a big spawning event is very important because males and female corals cannot move into reproductive contact with each other
Corals spawn their gametes in the sea, because colonies may be separated by wide distances, this release must be both precisely and broadly timed, and usually occurs in response to multiple environmental cues. Spawning events are incredible shows to watch…
Those reproductive moments are still not fully understood just as many other aspects about corals.

Are there any Super Coral in real life ?

Kind of!
Scientists are exploring some “coral defense” mechanisms and surprising resilient species, to understand how they adapt themselves to warming and ocean acidification.
This pioneering research on cross-species coral hybrids, inoculations with protective bacteria and even genetic engineering could give birth to new “super corals” able to resist global warming.

What is the goal of the game?

The goal is to reach the Super Coral, a CryptoCoral with the most reseastant genes. You can reach it by successively reproducing your CryptoCorals under the right circumstances in the Love Zone... The first ones to reach the super coral will win some awesome prizes ;)
But the main goal is for you to have fun! So explore the whole universe of CryptoCorals, unlock quests, try to create the most beautiful CryptoCoral, name it...

What are the rules in the Love Zone?

You need to own at least one CryptoCoral of the couple.
You can't breed one CryptoCoral with itself..
You can't breed CryptoCoral eggs.
You will need to pay some reefcoins if you want to reproduce with a CryptoCoral you don't own.

What is the Cooldown?

The Cooldown is the time your CryptoCorals have to wait to cool down after using the Love Zone. It increases with its sexperience and rarity.

Why do I have to wait to hatch my eggs?

Because it's nature! You have to be patient, particularly with rare newborn CryptoCorals...

What is a game season?

Each game season has its own super coral! During a game season, players compete in a race to reach the super coral.

What is a heat wave?

At the end of each game season, a heat wave strikes the reef: only the most reseastant CryptoCorals will survive.
The generation 0 CryptoCorals also survive but may mutate for the next game season.
