I think 10m isn't totally out of the question. Solana is at 100k right now, and there's about a factor of 100 of moderately low-ish hanging fruit I think? IDK for sure, @aeyakovenko / @seb_alameda would know more

Problem reaching 10M txs per second is more on the network side. Maybe on a local machine, but on a distributed geographic net? You could create 100 shards and have inter-shard sync, but then the chatter across shards might be too high with block time < 1s Interesting stuff

Oh yeah you def can't get 1 tx to have a latency of < 1/1m s, but you can do multiple in parallel without sharding using e.g. memory allocation (what Solana does)

CPU/Mem is not the problem here, as mentioned on a single machine testnet it would probably all work fine. But imagine shooting every 400ms, 10M transactions confirmations around to hundreds of nodes and synchronizing them all That's why L2 solutions are popping out.

10M is 20gbps, which is theoretically doable since pci4 bandwidth is 1tbps. My guess is in that less then 10 years from now 20gbps will be as common for consumers as 1gbps.

In 10 year we might see that. But it would mean that every single node / participant to the network has to have outstanding network speed and resources. Till today in most of the world 1Gb/s is still a dream. Isn't it better to avoid L1 having to handle it all?

Don’t bet against hardware :), it’s an exponential. Ending up on the wrong side of that curve is a death sentence. A $500 playstation has the specs to handle 1gbps/500ktps. I suspect that steady state load is going to be low and dynamic burst capacity will be more important.
