At web3 summit, Emin Gun Sirer presented his new project, Avalanche, which uses a new type of gossip-based consensus, Snowball. Here’s how he presented it - “there have been 3 major developments in consensus algorithms. The first is BFT from the 80s. Then there was Nakamoto consensus. And the latest development is Snowball”.
I propose that we use this in aeternity in a future hard fork. Of course, since there is no ‘block winner’ now, rewarding coins to people to run the nodes needs to be done in a different way. But with this consensus, and with a different coin rewarding mechanism, we could really incentivise people to run the node on their smartphones (excluding storage costs).
