What is the sacred meaning of "Du universe"? What changes will it bring to our lives
according to the answers given on the official website, we can learn that the universe is more like a game. By virtue of the concept of the universe, the Internet has formed a magical world, which is composed of various rare elements. In the "universe", everyone has his own small planet. Each user starts his own journey from his own planet through wormhole. When traveling, users will meet all kinds of planets, and each planet is allowed to be explored. On these planets, users may have unexpected gains
the concept of "universe" seems to be a bit abstract and has a sense of technology. It seems that this is also the trend of future games. In this digital universe constructed by elements, gravitation and planets, users can expand their own planets with the so-called "elements". The larger the mass of the planet, the higher the level, and correspondingly get many new functions. In this one, also applied to the knowledge of the universe and physics, so that the whole game has a sense of science fiction, eye-catching
when it comes to blockchain, many people will immediately think of bitcoin, a kind of digital currency. This kind of virtual currency can finally circulate like real currency, and it is very popular all over the world
so let's briefly introce blockchain. Blockchain is a kind of chain data structure that combines data blocks in order according to the time sequence, and it can't be tampered and forged by cryptography. Blockchain is also an important concept of bitcoin. In essence, it is a decentralized database
but the "universe" of network development is different from bitcoin. It is not a digital currency, but a game activity that everyone can participate in, which is equivalent to a digital society. The goal of the network is to let everyone find themselves in a network universe
the physical meanings of planet gravity, mass of aggregation elements and planet mass are all reflected in the game, but they don't give people a headache. They use a simpler way to let users participate in it. The more the mass of the planet, the more mysterious functions will be opened. In this way, all users will be motivated to move forward
at present, the proct of "Du universe" has not yet taken shape, but has a basic concept. On the first day of the release of "Du universe" procts, the official network will "air drop" 100 elements. Many friends who are interested in this game can't wait
in fact, it's not the first time that the network involves the blockchain, and the recent application "oasis" implemented by the network is one of them. So what is oasis? In fact, "oasis" is also a game, but the concept is different from "universe". Oasis uses "crystal" and "calculation power" as the currency of the game. The higher the calculation power, the faster the crystal will be generated
the network has made great efforts in the field of blockchain. It can be seen that the network wants to focus on cultivating itself in the field of blockchain, but not every successful innovation can succeed. We are confused about "universe" and have expectations
I hope this answer will help you
