Analysis of blockchain transactions is also consolidating around middlemen too! If you're trying to read data off of the blockchain for professional analysis purposes, you'll find a lot of working analysts are using sites like Dune.xyz, which stick a SQL interface in front of data slurped from the blockchain and charge a pretty penny to access it.
(Wouldn't be surprised if they're slurping from middlemen services themselves)
We have built an open source tool that you can connect to any node (on an Ethereum-based blockchain) and instantly start building datasets about contracts that you care about. All you need is their ABI.
We are committed to keeping this code free. Our policy is only to charge for our operational expertise, but all the code that we use is open source. We are in the process of opening our platform up for decentralization (so anyone can contribute node time, storage, etc.).
