What is the fastest way to get blocks in the blockchain?

[SergFras]

I’m working on a blockchain application in the Base network and have encountered some issues.

My main goal is to receive the newest blocks as quickly as possible. I’ve tried several methods using the web3.py library and realized that the weakest link in my setup is the RPC provider I use to fetch blockchain data.

I’ve tested providers like dRPC, Infura, QuickNode, and Alchemy, but I’m still getting new blocks with a 3–4 second delay after they are created. During this time, 1–2 more blocks are already produced, which causes me significant financial losses since I need to be the first to receive these blocks.

Here are my questions: 1. Are there any providers that deliver block information instantly, without delays? 2. Would running my own node help solve this issue and allow me to receive new blocks as quickly as possible?

I would greatly appreciate any advice or recommendations!
