Hi all,

I was wondering if I could get some feedback on an idea that popped up, mining related.

I'm going to ask to make some assumptions here. The idea is that, by grouping miners, the mining process is distributed, effectively raising the amount of transactions per second. Grouping in this case is not the same as a pool, each miner in each group still would aim for his own profit. Also note that it's not about splitting the network, the P2P network remains intact, it's about distributing mining capacity.

Suppose that it would be possible to group all current Bitcoin miners (say, a protocol groups the current population of miners into two groups, group 1(g1) and group 2 (g2)), like Kademlia but with two buckets (could be more if the number of miners increase, but let's stick to two for now). Each group mines specific transactions (transactions are labelled 1 (t1) or 2 (t2) (t1s go to g1, etc)), and the same protocol also ensures that both groups can submit their found block simultaneously without creating a fork. I'm aware that's not really possible in Bitcoin's current blockchain implementation, but my question is about the grouping of miners, would that be a no-go from a centralization perspective? Thanks.
