Releasing ESPLR - a local ETH block explorer.

Big problem of ecosystem is reliance on 3rd party RPCs (infura, alchemy, quicknode). Also reliance on 3rd party explorers (etherscan). They track users: it makes system one big panopticon.

Local nodes can make the situation better!

PC with an archive node only costs $40/mo or $500 one-time. Esplr only needs RPC URL of an archive node. It can view transactions, account balances and token transfer history (unique feature). https://github.com/paulmillr/esplr

Is it fair to say that etherscan tracks users? What makes Ethereum a Panopticon is the transparency of the chain data. Not the third-party applications that visualize that data. Or is there something that I’m missing?

Ethereum. L2s. DeFi. 

I like privacy and data security.

Yes it is fair to say that. They log all combinations "who accessed address" - "ip originated". They share this data on request

I’m not expecting them to. That was just a very specific combination that you mentioned. Not all businesses keep analytics of full IP address linked with specific page views, especially as it can be considered personally identifiable information within some countries privacy laws.

That's how ANY big service operates. No one is going to jail for you.
