I used to think proof‑of‑stake was the only alternative to proof‑of‑work. Then I discovered Nano’s ORV (Open Representative Voting). It’s a unique blend: no rewards for staking, but a vote based on account balance. Representatives are chosen by users. That’s not just a technical detail. It changes the incentive structure entirely. There’s no money to be made by hoarding, so the network stays liquid. I’ve been running a representative node for two years, just to help the network. It costs almost nothing. Satoshi wanted a system where participation was easy. Nano took that to heart. If you want to understand that design choice better, this write‑up breaks it down without jargon.
