Do you make money with game items?Gamers want to know "NFT and Blockchain" Super Introduction | Inside Facebook Twitter Hatebu Pocket

When you play Pokemon and get Pikachu, is that Pikachu in the world?Basically so.In the Pokemon world, even if it looks exactly the same Pikachu, one caught one is treated as another individual and cannot be copied on the game.However, some people can falsify and copy game data.Of course, it will be an illegal remodeling, but it is possible or not.

Then, what would happen if we could almost completely prevent data falsification and make a special Pikachu that can't be copied?It is just one special Pikachu in the genuine world that no one else has.You can never copy it.There are surely people in the world who want Pikachu.Some people will give money.And a lot of money.

The day may come to reality.That's the story of NFT this time.

NFT and blockchain

NFT is an abbreviation of Non-Fungible Token, which stands for non-alternative tokens in Japanese.An alternative, or instead of a substitute token.

Very simple, it's like a digital data certificate.It can be proved that it is the only one and one that cannot be duplicated.In other words, it's the story of Pikachu.This Pikachu is associated with NFT and prove that you are one Pikachu in the world you have obtained.

If you talk a little bit, NFT uses blockchain technology.The blockchain is a technology for computers to record digital data on multiple computers, with multiple computers.The record of the transaction is called a block, which is a blockchain because it connects like a chain.

One of the features that changing one place is very difficult to falsify, as it will be inconsistent with all the data that connects to it, and it is one of the features that can not be copied NFT using this.It is proven as.

Trading card game using NFT

There are already many games using NFT, but I would like to explain in trading card games as an easy -to -understand example for game users.

Trading card games such as "Yu -Gi -Oh! OCG Duel Monsters" and "Pokemon Card Games" are sold in packs in the shop.It is a physical card that can be picked up by paper.Cards that come out of the pack are bought and sold between shops or individuals, and in some cases, premiere and expensive.

However, digital card games such as "Shadow Bath" and "Hearthstone" are different.You can buy a card in a pack, but you will not be able to replace it or buy or sell.In the first place, items obtained in online games are mostly not owned by players.The items of these games are not just as possible because they can be used.Some users buy and sell game data for each account, but they are basically prohibited by terms of use.

With the introduction of NFT, this common sense changes drastically.When the player gets a card from the game, it has become a player's own, and a game that can be bought and sold has appeared.A digital card game using NFT called "Crypto Spells" has been released in June 2019 from Japanese manufacturers.

In "Crypto Spells", players can freely buy and sell cards.So there is a card market price.Also, rather than playing games, it seems that some people play speculative purposes, that is, to make money.

An interesting feature unique to NFT is the “issue limit”.If it is a normal digital card game, the card will be discharged infinitely if the user charges.However, Cryptus Spells has a limited number of cards to be sold in order to maintain the value of the card with the upper limit on issuing cards.The highest rarity is Limited Legend.Only nine sheets are issued in the world.The sales method is completely different from a normal game, and it is sold in auction format.And the price is hundreds of thousands of yen.It seems that common sense is completely different from the previous games.

■ Problems and issues of NFT games

By using NFT, items and characters gained in the game become the ownership of the player, and such an attempt has already begun to create an economic zone by buying and selling.Of course, in addition to trading card games, for example, lands on games are buying and selling, and users' creations are subject to buying and selling.

NFT has many possibilities, but there are also problems and issues.Valve, which operates the Steam of the PC Game Platform, is a "blockchain that allows you to publish or replace the cryptocurrency or NFT in the guidelines for a partner that provides the game to Steam.We have added a sentence called "application built based on technology.This means that Games using NFT are no longer sold on Steam.

The reason why Valve banned NFT is not clearly announced, but there are some problems that arise by guarantee the value of the game data that users get.

For example, gambling problem.If data such as gachas and items that can be obtained in the game intervene and obtained, gambling may be established.There is also a problem with the landscape law.The items you can get by playing the game are valuable, and if you own it, this may be recognized as a prize.If the item distributed in the game is a prize, it will only be distributed to the limit of the limit on the scenic table law.

As new games have never been seen before, these legal interpretations may be difficult to judge, and it is thought that legal development will proceed in the future.There should be a company that considers this as a risk.If you are a platform where many publishers games are distributed, you may think that the risk is particularly large.

Alternatively, there is a concern that the target of the speculation will cause entertainment.If the attractiveness of speculative is more attractive, the more the fun of the game and the balance of the balance, the game will naturally be uninteresting, and existing game users will be separated.

The world of new games is being born with technology such as blockchain and NFT.It is exciting for the appearance of new technologies, but on the other hand, there are many problems that need to be solved to spread.
