Hääl is the first protocol with a proof-of-concept for Secret Voting on Public Blockchains.
It reproduces the full process of an election, generating a proof-of-vote receipt and validating it on chain.
The protocol assures all votes are encrypted and just the result is decrypted, with a zk-proof-of-result.
Noone can see for whom you cast the vote, but everyone can count, check and audit all the encrypted votes in real-time.
