Thanks for calling that out. I was surprised there was zero mention of Stellar.

The reason Stellar was appealing was because Stripe invested into it. I wonder if Tempo is using a similar consensus mechanism as Stellar (and/or Ripple)

Stellar was my first thought too. I predicted it would take over the low-value transaction / fintech crypto space with their fast transaction times, low fees, spam protection, and bank buy-in but it just went nowhere. sigh
