EthSign Shows How Identity Becomes Portable, But Not Uniform
EthSign feels simple on the surface. Sign a document, anchor proof on-chain, move on. But once you use it across contexts, portability becomes more complicated.
A signature can travel. The proof remains verifiable because hashes are anchored, while full data often lives off-chain. That keeps costs manageable and allows documents to scale.
But interpretation doesn’t travel as cleanly. The same signed document might carry different weight depending on where it’s used. One platform treats it as strong verification. Another sees it as just a reference.
So identity becomes portable, but not uniform.
That gap is where friction shows up. Not in verification, but in how much trust each environment assigns to the same proof.
EthSign solves authenticity well. It does not standardize meaning.
And that difference matters more than it looks, especially when systems start relying on these signatures for decisions rather than just validation.
