2. Obtaining access to exclusive events. Some organizers of the events can provide access to exclusive measures or content only to those who have a certain POAP token.

3. Collecting. POAP can become collectible items, especially if you have received them at events that have great value to you.

4. Advertising. The organizers of the events can use POAP as a way to attract participants for future events, offering them the opportunity to get unique tokens as a reward for participation.

In general, PoAP is an innovative way of communication between the organizers of the events and participants, which allows you to make sure and keep in touch with the audience.

What is Proof of Attendance Protocol Paint Parties?

POAP Paint Parties are events in which participants can create paintings and receive unique PoAP tokens for this, which confirm their participation in the event.

How to take part in the Proof of Attendance Protocol Paint Party party?

To take part in the POAP Paint Party party, you first need to find the closest event in your region. This can be done, for example, using a search on the Internet or on social networks, such as Twitter or Discord.

When you find the event, check if there are the necessary tools and materials that are needed to create a picture. Typically, the event provides all the necessary materials, but sometimes participants should bring their brushes and paints.

In addition, make sure you registered with the event and received confirmation of your participation. As a rule, Poap Paint Parties uses a ticket system, and you must register in advance to gain access to the event.

When you attend the event and create your picture, you will be given a unique PoAP token, which confirms your participation in the event. You can save this token in your Cryptocurrency wallet and use it to demonstrate your participation in the event.

What is Bitcoin (BTC)?

Bitcoin is a decentralized cryptocurrency originally described in a 2008 white paper by a person or group of people using the pseudonym Satoshi Nakamoto. It was launched shortly after, in January 2009.

Bitcoin is a peer-to-peer online currency, which means that all transactions occur directly between equal, independent network participants, without the need for any intermediary to resolve or facilitate them. Bitcoin was created, according to Nakamoto himself, to allow "online payments to be sent directly from one party to the other without going through a financial institution."

Some concepts for a similar type of decentralized electronic currency predate BTC, but Bitcoin differs in that it is the first cryptocurrency in the world to enter into actual use.

Who are the founders of Bitcoin?

The original inventor of Bitcoin is known under the pseudonym Satoshi Nakamoto. As of 2021, the true identity of the person — or organization— behind the pseudonym remains unknown.

On October 31, 2008, Nakamoto published a Bitcoin whitepaper detailing how a peer-to-peer online currency could be implemented. They proposed using a decentralized register of transactions packaged in packages (called "blocks") and protected by cryptographic algorithms — the whole system will later be called a "blockchain".

Just two months later, on January 3, 2009, Nakamoto mined the first block in the Bitcoin network, known as the genesis block, thereby launching the world's first cryptocurrency. The bitcoin price was $0 when it was first introduced, and most bitcoins were obtained through mining, which required only moderately powerful devices (such as PCs) and mining software. The first known commercial Bitcoin transaction occurred on May 22, 2010, when programmer Laszlo Hanyech exchanged 10,000 bitcoins for two pizzas. At the price of bitcoin today in mid-September 2021, these pizzas will cost an amazing $478 million. This event is now known as "Bitcoin Pizza Day". In July 2010, Bitcoin began trading for the first time, with the Bitcoin price ranging from 0.0008 to 0.08 USD at that time.Однако, хотя Накамото был первоначальным изобретателем Биткойна, а также автором его самой первой реализации, он передал ключ сетевого оповещения и управление репозиторием кода Гэвину Андресену, который позже стал ведущим разработчиком в Bitcoin Foundation. На протяжении многих лет большое количество людей внесли свой вклад в улучшение программного обеспечения криптовалюты, исправляя уязвимости и добавляя новые функции.

Репозиторий исходного кода Биткойна на GitHub перечисляет более 750 участников, некоторые из ключевых из которых - Владимир Ван дер Лаан, Марко Фальке, Питер Вуйле, Гэвин Андресен, Йонас Шнелли и другие.

As an example, let's take nocturnal insects — the size of their visual organs often does not exceed a match head, but they perfectly navigate the terrain in dim light, deftly avoid obstacles and detect even weak movements around.

Imagine that you find yourself at night in a tropical forest, under the crowns of which the light of the moon and stars does not penetrate. It will seem to you that there is not a single light source around at all. But this will be true only for our imperfect visual apparatus — in fact, the space around will be filled with single photons. For the human eye, their number will clearly not be enough to get at least a dim picture of the surrounding world.

However, the visual organs of nocturnal insects and animals are much more sensitive. For example, the visual organs of the nocturnal tropical bee of the species Megalopta genalis absorb only a few photons, but this is enough to navigate in a confusing and dense tropical forest even when the light levels are at extremely low values. A similar behavior is also distinguished by the nocturnal European butterfly of the species Deilephia elpenor from the hawk moth family. This would not have been possible without certain tricks on the part of the insect.

Using the example of the hawk moth, scientists studied the work of the visual centers of the insect's brain and found out that thanks to a certain work of neurons, the butterfly is able to put single photons into a single picture, which it caught at different points in space and time. As more and more photons are captured, the picture of the world in the head of Deilephia elphenor becomes brighter — this can be compared to a long shutter speed of a camera when photographing.

True, it will not be possible to achieve high-definition images, but the insect can form an idea of the surrounding world and even see it in color!

This ability, which is called "neural summation", is also possessed by other nocturnal insects. Of course, the final image will be far from ideal — for example, fast-moving objects will not be recorded, but such a way of visualizing the world shows how complex and inventive the visual center of even small creatures is.
