What is the best Farcaster block explorer? I tried casterscan.com but it seems to be down. Goal: I want to demonstrate on-chain cryptographic verifiability of statements. “I know that X posted Y at time Z, because I have the digital signature from X, the hash of Y, and the on-chain timestamp of Z" @dwr.eth @v

@dylsteck.eth for casterscan I don’t think there’s a simple way to visually show that right now. The FID <> Ethereum address mapping exists on Ethereum L1 Goerli and Farcaster Hubs verify that to allow for casts to be stored and propagated on Hubs. Good feedback to make this clearer to demonstrate.

There’s isn’t a great block explorer rn, but you can do it programatically. Good hackathon project for someone! Since FC messages are stored off chain, you can prove that X said Y with a signature but not reliably that it happened at time Z (yet)

A chain “⛓” button that stores the hash of the post on-chain would be cool. If posts are pre-signed by the caster, then others could pay the gas fee.

If nothing like this exists, I can hack it together at EthCC 👍️

👋 Thanks so much for the shout-out @balajis.eth! Woke up to an error with my database that I’ve been fixing all morning, but it should be back up very soon and I’ll ping you when it’s back up

@tldr
It’s theoretically interesting here that even when we have the above, we only truly know “the controller of private keys of person X” posted Y at Z. To know it was person X themself, we would want in addition some kind of ID verification at time Z-1. Anyone besides WorldCoin working on this?

This isn’t an onchain convo.

Farcaster doesn‘t leave an on-chain proof as far as I know. It stores your EIP712 signature in a Patricia Merkle Trie but it deletes data after a year

Farcaster posts don’t touch any blockchain - they’re not onchain. So, timestamps are subjective rather than objective and this isn’t really possible. There’s cryptographic verifiably of who posted what, but not when.
