I saw Solana's latest ATH—over 150 million transactions per day, and I was wondering why this number gets all the attention.

So I spent some time really understanding what’s happening behind the curtain.

Here’s the hidden truth: most of those transactions aren’t really transactions in the sense we think of.
About 60% are validator vote transactions—if you count that the same way on other major chains, the actual throughput drops significantly.
Plus, 20-40% of the remaining activity are failed transactions.
So the real picture looks bigger than it actually is.

But wait, there’s something even more important.
Solana requires 12.8 seconds for true finality—meaning you’re not really sure your transaction is permanent until after that window.
Compared to NEAR, which achieves 1.2-second deterministic finality, where your transaction is mathematically immutable before it even confirms on Solana.

I learned this while working on cross-chain infrastructure.
Everyone talks about throughput numbers because they make headlines, but finality is the real game-changer for payments and DeFi.
That’s what changed the whole picture for me.

This Solana naughty secret is worth understanding if you’re serious about blockchain fundamentals.
Throughput is just the headline, but finality is the true measure of reliability.
