5) So, if your blockchain wants to be theoretically able to house a top company without being a huge drag on its business model, it should maybe be targeting something like $0.0001 per transaction in gas costs.

6) How doable is that? Well, right now, fees on Solana are ~0.000005 SOL, which is roughly..... $0.000125.

7) How will that change over time? I don't know! Here are some thoughts, though.

8) First, what if demand outstrips supply for transactions by a massive amount? Well, then we just get auctions, like what Ethereum has, and prices could diverge upwards. And if supply outstrips demand?

9) Over time, nodes will increase in TPS, and maybe cost too. Which increases faster? TPS, probably. As computers get more efficient, so do Solana nodes. So the cost per tx should go down over time if demand doesn't keep up.

10) On the other hand, more validators --> greater compute cost per tx. Right now, Solana has ~50k max TPS and ~600 validators. If it's going to grow to ~10m TPS and ~10k (?) validators, that would be: --500x growth in TPS --20x growth in # validators --??? change in cost/node

11) So theoretically cost per transaction might go down by a factor of ~25, though possibly some of that will be counteracted by other factors. Which is to say: idk, it kinda seems like Solana is on path to be cost efficient for huge companies over the next ~5 years?

12) I'm sure I messed up lots of things here --

@aeyakovenko

thoughts? And for others -- how does this math work out on other chains?

and

how did u arrive at 100k~10M transactions for largest companies?

Googles revenue / cost per impression ~= 2m things per second. My guess is that’s basically 50% of human events per second.

basically googled around for things like Twitter likes/second, Facebook likes/second, NYSE trades/second, etc. another way to ballpark this: if it's a B2C business, and you have 1B users, that's 10k user-days/second. So if the avg user interacts ~10x/day --> 100k TPS.

Thats actually pretty clever ngl

Would smart contract complexity impact these numbers, say a call option required more lines of code than a buy and execution time is longer? Similar to what we see in Ethereum with different gas prices depending on transaction complexity?
