Idk if you watched the video but the reason it works is mentioned in the video, if not explored in detail.
You have a digital id and a digital signature that is tied to you as a citizen.
Each vote has to be signed with your personal voter signature.
I watched though about half of it, before concluding that this video is only going to be a summary video that won't answer my questions fully.
Digital ID and Digital signature are absolutely necessary, though depending on how those two are implemented I could still see fraud and vote manipulation being feasible. I was hoping someone with more knowledge about how Estonia is doing its security and verification systems to ensure records aren't being modified maliciously.
I’m happy to revisit and explain, but I don’t have much time to type right now - the wikipedia page for estonia has great info; you will need a basic understanding of cryptographic hashing and merkle trees
There should also be a 30sth page doc about how the e-voting machines are set up, configured and secured somewhere. But it is in Estonian and I can't be arsed to find it now

It's actually fascinating. Asymmetric keys with public keys hosted by the government and the private key in your ID.
A 4 digit pin1 code is required to use the authorization key and a 5 digit pin2 is required to use the signing key.
The average Estonian signs 50 documents per year using this method.
Everyone in Estonia has to have an ID card, which contains the RSA keys and x.509 certs for giving digital signatures.
And all the software is open source :)
