Currently there are three RAM applications on the EOS chain:
1. BRAM developed by the BOX team can be exchanged for free 1:1 into BRAM using RAM resources, and can be used for market making and mining in DEFIBOX!
2. Droplets developed by node Greymass can use RAM to generate DROPS, and mine SCRAPA tokens by destroying and generating them every day.
3. There is a message board developed by Guashen in the community. You can leave messages by pledging RAM and get rewards! And you can delete the message after one year and the RAM will be returned to the EOS account!
