Estonia has this system for a decade already btw and uses block chain to make it transparant and for integrity, and the verification app will be zero-knowledge proof, and is open-source. Literally the best two specs you want for privacy… The only thing I would want is a decentralized system where you can get verified by showing your ID to your local municipal services, not uploading it.

But the chat control has to go away asap fr
maybe a compromis for chat control would be a decentralized database of photo hashes that are scanned by the chat control app where only trusted organizations for childrens safety can add hashes to, supported by block chain so we have full transparency of who adds what… wdyt of this?

This way there is no single point of control. Blockchain provides full transparency because every addition of a hash is recorded as a transaction that anyone can verify, showing who added it and when, and since the blockchain is immutable, hashes can’t be secretly altered or deleted. Digital signatures prove which trusted org added each hash.
