Hello,
I would like to inquire about the waves wallet. Has two versions, PC and online. The only difference between the two is the online version uses a web browser? Are they both essentially online clients? If so, doesn't that mean the blockchain is stored at some centralized location and no one really owns their coins?
Every client is connected to nodes. All your privates keys (seeds) on generated client side.
Waves is a decentralized blockchain, likes all the others.
