Nekoyume has included players’ action information in a blockchain 
to implement fantasy role-playing in a decentralized environment.
When players hunt monsters, sleep, or give gifts to other players, this information is securely shared in a blockchain.

What can I do?

⚔ Fight

You encounter a nearby monster and battle it. A result over 10 is a big success; if it is between 7 and 9, you will be counterattacked by the enemy. If you get 6 or less, something will go wrong.

💤 Sleep

Fall asleep in your bed and regain your hit point. If you are seriously wounded by an enemy, you can fight again after recovering your hit points by sleeping. If you are lucky, you might have a memorable dream.

🗣 Say

You can talk to players who is following you. If you leave something important, that story will be addressed by others.

➡ Send

You can pass on your items to other players. You can change your bandages to keep your colleagues from injury, or you can trade items for gold. Trading is the key to growth!

Preview network source code will be released in April 2018!
