Zerocoin Protocol Vulnerability
- Got a serious vulnerability back in 4-2019. It basically meant their protocol was broken and most projects utilizing Zerocoin stopped their private send functions afterwards. Projects affected were: ZCoin itself, PIVX, Veil, Gravity Coin, NavCoin (who was developing a Zerocoin variant called ZeroCT on their testnet) and NIX. On 19-4-2019 core developer Peter Shugalev found the root cause of the issue and confirmed that it was a failure in the cryptography of the Zerocoin protocol and that it affected all Zerocoin implementations. Forged coins were created, but not exceeding 1% of the circulating supply. The issue was not from a coding error, but from a cryptographic flaw in one of the proofs in the Zerocoin protocol that has existed since its inception.
