Yes This! So many people seem hung up on growing the block size! If gaining a higher tps throughput is the main aim, I think that this proposition to speed up block creation has merit! Yes it will lead to an increase in the block chain still due to 1mb ~1 minute instead of ~10 minute, but the

So if the server pushes new block header candidates to clients, then the problem boils down to increasing bandwidth of the servers to achieve a tenfold increase in work distribution. Most Stratum pools already do multiple updates of the header every block period, bandwidth is really

I proposed the same thing last year (there's a video of the presentation I was giving somewhere around). My intuition was that this would require slowly reducing the inter-block time, probably by step reductions at particular block heights. Having had almost a year to think about it some more

The propagation speed gain from having smaller blocks is linear in the size reduction, down to a small size, after which the delay of the first byte prevails [1], however the blockchain fork rate increases superlinearly, giving an overall worse tradeoff. A high blockchain fork rate is a symptom of
