The frivolous use of block space - ie. to increase the demand for block space - is not encouraged. Although it is possible you may write chess moves on a wrap of dollar bills and send them to your friends, nowhere that I know of has this been recorded in a ledger as a valid past time.

Secondary goal is to have fun and contribute in increasing demand for block space. Maybe an app for developers to play chess, friendly competitions, learn and share new things. If chess sounds boring it can be replaced with any 2 player game that works for such setup and can be played with patience over few hours/days. Spam? Sorry zero fee transactions do not work anymore. In fact, nothing below 1 sat/vbyte fee rate would work and all transactions will pay fees that are required long term. OP_RETURN is used by many projects and excluded from UTXO set. Let me know if something looks wrong. I won't be working on this as busy with another project and recently started contributing in Wasabi. -- Prayank A3B1 E430 2298 178F
