Here’s an odd question for the community: Given a public address (of any type [ETH, BTC, etc.]), what is the minimum amount of characters one could/should display for that information to be unique enough but not easily discoverable via a block explorer?
For example, if I have address:
0xf440635601f3d3085a1d82d874667c9b2623b842 (don’t get excited I just pulled a random one from Etherscan), is
0xf44...842 good enough to use in a “here’s some consistent information regarding an address, but I don’t want someone to know the complete address” context?
I’m being vague with my use-case on purpose.
Edit: I guess what I’m really asking is: how hard would it be to search for an address across any given chain if you only knew the first and last three characters? Does that difficulty increase exponentially by making it 2 and 2, and if so, how long would that take?
