Need for a Signature Explorer?

So there are all these block explorers out there, right? Some just show basic blockchain info, while others focus on UTXO and pruned data. But I was thinking… wouldn’t it be cool to have a signature explorer? It could help with z-values and signatures from transactions, way easier than coding it from scratch.

Just to point out, z-values aren’t stored on the blockchain, so you can’t just extract them. They need to be calculated, and that means the explorer would have to store tons of extra data, like tens of gigabytes. Not sure how useful that would really be.

Someone brought up an OP_RETURN explorer recently. That could be more interesting, like searching for specific messages in the blockchain. Just saying, might be a better idea than a signature explorer.

Blockstream's explorer already shows the signature for each input if you click on "Details +" next to the TXID. It’s hidden by default since most users wouldn’t really care about that info. Might want to check it out.

I’m not just after the (r,s) pair, that's too easy. I’m looking for data behind a specific z-value. Like, you can find a transaction, see the signature, and get (r,s), but to verify fully, you need the z-value. It’s not just a simple transaction hash, it’s way more complex.

It’s mainly just SHA256 hashes, so it’s not super heavy in most cases. But yeah, that 1% could be tricky with those unusual transactions that mess with things like FindAndDelete.

Yeah, I know it’s not the same as the transaction hash. I actually showed how to do it before. Did you think you only needed the signature? Anyway, there’s a tool at 2coins.org for legacy transactions that does just that. You paste the TXID, and it gets the hash. But not sure if it works for SegWit or TapRoot.
