The Mission

The Oceanos are the protectors of the Seven Seas. For hundreds of years, they’ve been responsible for the protection of an ecosystem that is essential for the survival of human existence: the oceans, the lungs of our planet.

The Oceanos clean the oceans and help maintain the balance of our atmosphere, guaranteeing health, safety and food for all species. But in recent years, their treasured universe started to be invaded by an enemy created by mankind: plastic waste. Every minute, 1 truckload enters the oceans.

The Oceanos have decided to fight back to save the oceans’ fauna and flora. They have gathered a powerful team of 3’335 selected members, every single one of them helping to fight plastic pollution.

These fantastic creatures live in the Oceanverse, and they need our help. That’s why the Oceanos have partnered with a real world label: #tide ocean material® . #tide is an international award-winning company, collecting plastic on islands and along coastlines and upcycling it while creating a strong environmental and social impact.

Аукционы NFT — это основной способ приобретения NFT пользователями. Вместо того, чтобы просто выбрать NFT и купить его, веб-сайты аукционов NFT — это место, где продавцы и покупатели взаимодействуют, чтобы договориться о цене NFT, который выставляется на аукцион. Даже традиционные художественные галереи, такие как Christie’s и Sotheby’s, включили NFT в свои каталоги и регулярно проводят известные аукционы NFT.

Анализ, проведенный Consensys, компанией-разработчиком программного обеспечения, которая поддерживает инфраструктуру Ethereum, показал, что произведения искусства, основанные на крипте, в настоящее время составляют 10% всех продаж произведений искусства по всему миру. Отраслевой отчет DappRadar за 2021 год показывает, что рыночная капитализация Топ-100 лучших коллекций NFT не показывает признаков замедления и увеличилась во второй половине 2021 года, при этом проекты метавселенной также получают свою долю пирога.

Что такое NFT аукцион?

На аукционе NFT продавец устанавливает минимальную цену на определенный период времени. Покупатели могут делать ставки на то, сколько они хотят потратить на NFT, если это больше минимальной цены. После этого NFT продается тому, кто предложит самую высокую цену в конце периода продажи.

Что такое сайт аукциона NFT?

Сайт аукциона NFT — это онлайн-рынок, на котором продаются невзаимозаменяемые произведения искусства, и покупатели могут приобрести их с помощью криптовалюты, такой как Ethereum. Большинство маркетплейсов взимают комиссию за транзакцию и требуют, чтобы вы создали у них учетную запись, которая обычно бесплатна.

Крупнейшие платформы и маркетплейсы NFT

Вот самые известные торговые площадки для покупки и продажи NFT.

Как работают аукционы NFT?

Минимальная сумма ETH, которую вы готовы взять за NFT, называется начальной ценой. Коллекционеры смогут увидеть начальную цену на платформе или торговой площадке и не смогут предлагать цену ниже начальной цены.

Помните, что к окончательной цене продажи вашего NFT будет добавлена плата за обслуживание в размере 15%, поэтому имейте это в виду при определении начальной цены. При достижении начальной цены NFT начинается 24-часовой обратный отсчет, после чего аукцион автоматически закрывается. Таймер обратного отсчета будет сбрасываться на 15 минут для каждого предложения, размещенного в последние 15 минут обратного отсчета, до тех пор, пока не будет сделано больше ставок.

Коллекционеры могут делать только ставки, равные или превышающие вашу начальную цену. 24-часовой аукцион начнется после того, как будет сделана первая ставка. Все последующие ставки должны быть на 10% выше или на 0,1 ETH выше текущей ставки, в зависимости от того, что ниже. Вы можете использовать социальные сети, чтобы вызвать интерес к вашему аукциону и продвигать больше ставок. Если после того, как коллекционер подаст заявку на резервную сумму, не будет получено никаких других предложений, объект будет продан первому участнику торгов.

Продления могут работать вечно, если в последние 15 минут аукциона не будет сделано ни одной ставки. Добавление 15-минутных продлений дает каждому покупателю последний шанс сделать ставку, а произведения искусства достигают своей полной рыночной стоимости.

Крупнейшие аукционы NFT на сегодняшний день

69 миллионов долларов США, Март 2021, Christie’s

Майк Винкельманн, также известный как Бипл, ранее в 2021 году продал «Everydays: The First 5,000 Days» (2021) на Christie’s за 69 миллионов долларов; что сделало его одним из самых высокооплачиваемых ныне живущих художников в мире. Продажа была исторической. Мало того, что работа получила такую высокую цену, она также эффективно распространила лихорадку NFT по всему миру искусства.

2 Beeple, Crossroads

$6.6 миллионов долларов США, Февраль 2021, Nifty Gateway

На первой продаже Beeple NFT «The First Drop» в октябре 2020 года первоначальный покупатель понятия не имел, какие произведения искусства он получит. В зависимости от исхода президентских выборов в США было два возможных визуала. После подсчета голосов и завершения работы над картиной, изображающей побежденного президента Дональда Трампа, лежащего голым и покрытым граффити на обочине дороги, коллекционер продал ее по цене, в 100 раз превышающей стартовую цену продажи.

3 Beeple, Ocean Front

$6 миллионов долларов США, Nifty Gateway, Март 2021

Работа, созданная как NFT, называется «Фронт океана» и рассказывает о текущей проблеме изменения климата Земли. На нем изображено дерево, взгромоздившееся на изображение трейлеров и транспортных контейнеров, стоящих на платформе на дне океана. Художник пообещал внести доходы в некоммерческую организацию Open Earth Foundation.

Вывод

По мере роста интереса к NFT платформы, которые используют «широкий» подход, уменьшая трения, упрощая вход для новых пользователей и позволяя участвовать максимально широкой аудитории — эффективно ценя масштабируемость больше, чем децентрализацию и безопасность, — получат более широкое распространение и рост.

HUMAN ONE

Для такого художника как Beeple картина стоимостью 6 млн долларов — не предел. Один из его арт-объектов под названием HUMAN ONE был продан за умопомрачительные деньги. Без малого картина обошлась покупателю практически за 29 млн долларов. Объект выполнен на базе блокчейна криптовалюты Ethereum.

What About Fractional Ownership?

Fractional ownership is an exciting sub-niche of Web3, at the intersection of NFTs and DeFi. IT allows co-ownership of data IP.

Ocean provides two approaches to fractional ownership:

Data DAOs are a cool use case whenever you have a group of people that wish to co-manage data, or bundle up data for larger collective bargaining power. The DAO may be a union, co-op, or trust.

This has several variants. Each member’s data feed could be its own data NFT with associated datatokens. Or, there’s simply one data NFT aggregating datafeeds across all members into a single feed, and the feed is fractionalized by sharded holding of ERC20 tokens (1 above) or sharding the ERC721 data NFT (2 above). If you’re interested in starting a data union then we recommend getting in touch with our friends at Data Union.

Store Updater

The store updater can store, remove or update any arbitrary key value using the ERC725Y implementation (at the ERC721 level). The use case for this role depends a lot on what data is being stored in the ERC725Y key-value pair — as mentioned above, this is highly flexible.

The Project

Our intention is not to re-invent the wheel!

We want to use all available ideas and projects for the single purpose of getting our oceans rid of plastics

Q3 2022

All the Oceanos except of the President will be available in a pre-sale, open to our whitelist members. At this pre-sale, a preferential and reduced price will be applied.

The remaining number of these 3334 Oceanos will be sold afterwards, in the first drop. And the President will be sold at a special auction.

A total of 2 NFTs per person will be available on the day of the mint.

Q2 2023

The game will be designed on the estate that the Oceanos own in the Sandbox. Through this parcel, players will be able to control their NFT, which will receive different privileges depending on whether they are a Senator, Governor, or the President!

Thus, Oceanos holders will see themselves developing a real civilization where they can both own a part of the game, while helping to clean up the world’s oceans with the earnings from the transactions that Tide Ocean Material® will make and that will be used to develop the collecting points in the world.

Hierarchy of the Oceanos

The Oceanos are well organized. Everyone plays an important role in the protection of sea life, from the Citizen to the President.

Every Oceano Citizen supports a fisherman collecting plastic in the regions where #tide is actively sourcing ocean-bound plastic waste – in Thailand, Philippines and Indonesia.

The Governors load the catch on a longtail boat that connects islands with the mainland, where the material is further processed in Social Enterprises supported by Senators.

The Senators make sure the plastic waste is sorted and washed properly. Then, the clean plastic litter is sent to the next phase of #tide’s upcycling process. The transformation into a high-quality material that can be used for an endless variety of durable products.

The Vice President is guaranteeing that all the involved creatures work tentacle to tentacle and hand in hand. The VP also makes sure that all the workers are being paid fairly. For the Vice President, giving plastic waste a value and raising awareness is just as important as meeting the highest ethical standards.

The President is committed to exploring new territories and expanding #tide’s know-how to regions where it’s desperately needed: from Africa to South America.

Q1 2023

The team behind the Oceanos is also working on a potential script for a 3D movie by Reel FX Animation. This studio runs on the artistic bravery of 500 people and creates films for cinemas and streaming platforms. Hence, you might be possible to discover your NFT on screens around the world in the future.

Q1 2022

The community comes first. Our main goal is to make sure that you’re rewarded for your pioneering spirit.

We will create a whitelist for the first tickets to buy «The Oceanos».

We’ll do a Pre-sale for whitelist members and then go into a public sale. You will be able to mint your Oceanos directly on our website.

GIAN

The Deployer has a bunch of privileges at the ERC20 datatoken level. They can deploy new datatokens with fixed price exchange, or free pricing. They can also update the ERC725Y key-value store and assign roles the ERC20 level.

Fee Manager

Finally, we also have a fee manager which has the ability to set a new fee collector — this is the account that will receive the datatokens when a data asset is consumed. If no fee collector account has been set, the datatokens will be sent by default to the NFT Owner. The applicable fees (market and community fees) are automatically deducted from the datatokens that are received.

Once the first drop is completed, an exceptional lucky draw will be offered to early holders. They will receive a parcel of 1 x 1 in the Sandbox.

A screenshot of the holders will be taken on 4 days after the soldout in order to make a draw. Information about the draw will be communicated on Discord.

1 single Citizen makes sure that the equivalent of up to 50’000 plastic bottles are saved from threatening the environment. Our ultimate goal is to sell all the Oceanos and make sure that #tide can close the loop by collecting and upcycling 100 million bottles.

Everydays — The First 5 000 Days

Абсолютный рекордсмен топа Финтолка, NFT-объект Everydays — The First 5000 Days был продан за 69,3 млн долларов!

Stay Free

NFT — это не всегда про странные и ироничные пиксельные изображения. Иногда виртуальные объекты призваны привлечь внимание общественности. Одним из таких стал NFT Stay Free («Оставайся свободным»), который выставил Эдвард Сноуден. Изображение включает в себя портрет и автограф бывшего спецагента ЦРУ на фоне выписок по решениям суда. Известно, что коллаж выкупило объединение коллекционеров за 2 224 ETH (около 5,4 млн долларов в момент покупки). Заработанная криптовалюта пошла на финансирование Фонда свободы прессы.

Achievements

Our oceans are full of plastics and other human-made materials that damage biodiversity and whole ecosystems, their removal is our priority

Ocean and environmental literacy is key to protecting our planet and making sure there is a future for the next generations

Building A Community

We strive for a world in which people are aware that each and every one of us can make the difference

The Oceanos are a community of sea creatures that support #tide ocean’s activities in Asia. Yet, the success of this first drop could lead to establishing a project on a new continent: America. The Oceanos could help building a new team in Mexico, where plastic waste is taking the ocean over too.

Ready to join the movement ?

To be whitelisted, you need to have gone through the process of getting your ETH address pre-approved. This will allow you to mint an NFT at some predefined date and time defined by the NFT project team.

You will own a collectible that will help remove plastic litter from the oceans. In other words, your NFT will contribute to the journey of closing the circle of plastic waste pollution in the physical world. Holding an Oceano will also give you a special access to giveaways (Sandbox parcel, cashback etc.). Your Oceano may additionally be integrated in an educational animation movie. You will also be able to play a game on the Oceanverse with your NFT.

You will be able to mint 2 Oceanos.

You will receive your NFT on your wallet and be able to trade it or hold it. Check the roadmap to see what will happen after the mint.

The whitepaper is coming soon and will be downloadable here.

First up — let’s remind ourselves what NFTs are. You probably already know what the acronym stands for, non-fungible token, but what does that mean? A fungible currency or token is one that can be exchanged for another identical token or unit of currency (Dollar, Pound, Bitcoin, Ether etc). So the fact that NFTs are non-fungible means that there is nothing identical to exchange them for — they are unique! They are the equivalent of marked dollar bills. The “mark” is usually a hash stored in the NFT smart contract.

By far the most exciting application of NFTs is the potential for them to represent intellectual property (IP) on-chain. Regular readers of our blog will be well-aware of how interested we are in the application of NFTs representing IP. If you would like to gain a more detailed understanding of the background on this topic, we recommend reading:

Q4 2021

The Oceanos were created by humans who want to stop plastic pollution and save the oceans. We truly believe in the power of the NFT community and the metaverse. That is why we’ve partnered with specialists to create this unique collection of NFTs.

Every collectible will make an essential contribution: 80% of the funding will be used for #tide’s fight against pollution and therefor create an environmental, social and educative impact.

What Is Ocean Protocol (OCEAN)?

Through Ocean Protocol, publishers can monetize their data while preserving privacy and control, whereas consumers can now access datasets that were previously unavailable or difficult to find. These datasets can be discovered on the Ocean Market, where they can be purchased and later consumed or sold.

On Ocean Protocol, each data service is represented by a unique datatoken, which is used to wrap a dataset or compute-to-data service — this essentially allows third-parties to perform operations on the data without it ever leaving the secure enclave of the publisher.

OCEAN is a utility token that is used for community governance and staking on data, in addition to buying and selling data as the basic unit of exchange on the Ocean Market. The price of these datatokens is set by an OCEAN-datatoken AMM pool, which adjusts the price of the datatoken as it is bought and sold based on supply and demand.

Who Are the Founders of Ocean Protocol?

Ocean Protocol was co-founded in 2017 by an experienced group of consultants and entrepreneurs, who together have a wealth of experience in developing and growing high tech businesses.

The Ocean Protocol core team includes: Bruce Pon, an experienced international project manager and current CEO of BigchainDB; Trent McConaghy, an experienced engineer and AI expert; Cristina Pon, marketing director at both Ocean Protocol and BigchainDB; and Razvan Olteanu, who has more than 20 years of technical and management experience in senior roles.

What Makes Ocean Protocol Unique?

Ocean Protocol unlocks access to data that would previously be unavailable or challenging to access, by allowing anybody with sought-after datasets to tokenize their data and make it available on the Ocean Market.

This produces an additional income stream for data publishers while giving scientists, researchers, data analysts and anybody else access to more reliable data.

Ocean Protocol provides the tools needed for firms to build and launch their own data markets, by either directly forking the Ocean Protocol, or by using the supplied Ocean Protocol React hooks. It also provides extensive documentation to assist with this process.

Holders of OCEAN tokens can directly participate in the datatoken economy by staking their tokens on datasets on the Ocean Market. Stakers then become liquidity providers in the selected OCEAN-datatoken pool, and earn a fraction of the transaction fees generated by the pool.

How Many Ocean Protocol (OCEAN) Coins Are There in Circulation?

As of November 2020, a total of 414 million OCEAN tokens are currently in circulation. This is out of a fixed maximum of 1.41 billion tokens, which was set in the new Ocean contract deployed on August 21, 2020.

It will take a total of 50 years for the full OCEAN supply to be released, whereas a total of ~600 million tokens are expected to be in circulation by May 2022, and 1 billion tokens by January 2031.

Of the total Ocean supply, 20% is allocated to the project founders, 15% to acquirors (SAFTE purchasers), 5% to the Ocean Protocol Foundation and the remaining 60% will be distributed to keepers (those that run Ocean network nodes).

How Is the Ocean Protocol Network Secured?

Ocean Protocol previously operated on a proof-of-authority (PoA) sidechain, but this was scrapped to ensure datatokens remain compatible with the broader Ethereum ecosystem.

According to a 2019 blog entry, Ocean Protocol applied military-grade security practices when designing its smart contracts — ensuring they can be securely upgraded and deployed without opening up any attack vectors.

Where Can You Buy Ocean Protocol (OCEAN)?

Ocean Protocol (OCEAN) tokens can currently be traded on more than two dozen exchanges, including several top tier platforms — like Binance, KuCoin, Bittrex and Poloniex. As of November 2020, Binance is the most liquid centralized exchange for OCEAN, whereas Uniswap is the most liquid decentralized exchange for OCEAN.

OCEAN currently cannot be purchased directly with fiat currencies on any supported exchanges. But you can buy Bitcoin with fiat instead, and then exchange this to OCEAN.

How Are Data NFTs Implemented?

We have implemented data NFTs using the ERC721 standard. Our implementation has been built on top of the battle-tested OpenZeppelin contract library. However, there are a bunch of interesting parts of our implementation that go a bit beyond an out-of-the-box NFT.

OceanOnda V4’s data NFT factory can deploy different types of data NFTs based on a variety of templates. Some templates could be tuned for data unions, others for DeFi, and others yet for enterprise use cases.

ERC725y is incredibly flexible and can be used to store any string; you could use it for anything from additional metadata to encrypted values. This helps future-proof the data NFTs and ensure that they are suitable for a wide range of projects that have not been launched yet. As you can imagine, the inclusion of ERC725y has huge potential and we look forward to seeing the different ways people end up using it. If you’re interested in using this, take a look at EIP725.

Continuing the theme of flexibility, for a given data NFT, you can have one or more ERC20 datatoken contracts. Here’s the main idea: 1.0 datatokens allows you to consume the corresponding dataset. Put another way, it’s a sub-license from the base IP to be able to use the dataset according to the license terms (when you send it to the publisher). License terms can be set from a “good default”, or by the Data NFT owner. ERC20 fungible token standard is a natural choice for datatokens, because licenses themselves are fungible: one license can be exchanged 1:1 another. Using the ERC20 standard enables interoperability of datatokens with ERC20-based wallets, DEXes, DAOs, and more. Datatokens can be given (simply transferred), purchased on a marketplace / exchange, airdropped, etc.

You can publish a data NFT initially with no ERC20 datatoken contracts. This means you simply aren’t ready to grant access to your data asset yet (sub-license it). Then, you can publish one or more ERC20 datatoken contracts against the data NFT. One datatoken contract might grant consume rights for 1 day, another for 1 week, etc. Each different datatoken contract is for different license terms.

Ocean provides convenient methods to list ERC20 datatokens for sale, with fixed-price (atomic swap), or for free. Like any ERC20 token, datatokens may be listed in many decentralised exchanges (DEXes), centralised exchanges (CEXes), over-the-counter, or otherwise.

The manager can assign or revoke three main roles (deployer, metadata updater, store updater). The manager is also able to interact with the ERC725 data.

Однако CryptoPunk #7523 оценили ни много ни мало в 11,754 млн долларов. И ладно бы только один пиксельный аватар стоил миллионы. Коллекция CryptoPunks включает в себя 10 000 объектов, сгенерированных с помощью алгоритма и программного кода еще в 2017 году. С ростом популярности NFT стоимость каждого из нескольких пикселявых панков перевалила за сумму с шестью нулями. К примеру, объект #3100 продался за 7,67 млн, а объект #7804 за 7,57 млн долларов.

So What’s a Data NFT?

The data NFT smart contract holds metadata about the data asset, stores roles like “who can mint datatokens” or “who controls fees”, and an open-ended key-value store to enable custom fields.

Первое сообщение в Твиттере

Объект продали за 2,9 млн долларов в эфире по курсу на момент продажи. Деньги пошли на благотворительность.
