At 41:00 then why is blockhash even needed, or why does blockhash exist? If blockhehight allows for faster checks, since u can substract/add 150 or any number to it. What am i missing?
Thanks Andy. That really helped me understand blockhashes - something Ive been struggling with. I wonder if the priority fee txs were failing because the compute budget wasn't set? Does it default to 1,400,000 if you don't set it?
Hi! Can you explain how to make fast transactions like mev bots do? For example if I want to sell right after someone buy, how to get information and make txns so fast? 😮
To make txns fast I think there are many ways, like you could deploy yourself blockchain node then you could direct communicate with it, that will be faster than 3rd RPC node; Also, you could send multi-requests, just hope one of them successed. In this way to make sure your requests faster than others.

Thanks, Andy! I do appreciate you going into length with your explanations, as someone quite new to Solana. Great teaching!
Splendid compared to the plain docs!
4:00, you could also add seconds to windows clock in the bottom right so we could see the time exactly 😇
hhaha i love this dude and that long videos.. andy makes my day :))

i think default is 200k (per instruction)
Your video could have been 10 minutes long😂
Seriously though..really like your deep dives and learning a lot from you so keep up the long ones 👍
