Not a scam. It's names on bitcoin. They have gone down to 12 (i think) characters. So there is competition for utxos. But the good news is that these are all prunable OP_RETURNS so nodes dont need to store it. Should calm down in a few days. That's not to say they dont have scams planned! But this spike was known.

Not scam, it's bitcoin staking of Babylon:

Babylon - Staking Dashboard

Staking Dashboard

Sir this is a scam lmfao

OK I may have been wrong. Looks like it's a 5 block auction. I need to read more about this.

If it's not a scam, where the yield is coming from?
