The vulnerability discovered in Monero blockchain during its second audit could have been used for denial of service attacks. It could enable hackers to breach into Monero nodes thereby creating a large DoS attack. Using the same weak link, the situation of 51% attacks could have also been developed. But, developers have created a new Bulletproof protocol that has successfully closed all doors of above-said possibilities. The new protocol patched up a total of 8 critical issues, two medium-impact ones and 20 small vulnerabilities successfully found during the security audit.

Sadly, the live code also became the worst hit of the same old issue. Therefore, the report was halted and the team worked to resolve the issue as soon as possible. Otherwise, anyone could have used the information to attack the network. Soon after resolving the vulnerability, the Monero Research Lab and QuaksLab resumed their work.

The developers also patched four other major vulnerabilities those could have used by untrusted inputs into the system and to accept false proofs. QuarksLab ran audits and suggested people for on improving code practices to stabilize Monero in a better way for a bug-free performance.

The Bulletproof protocol is a much-improved version of Monero that resembles as a zero-knowledge proof (ZK-Snarks) tool. Monero team has proposed about the same for the first time in December last year. They opined it to be a perfect medium to make Monero stable and secure.

It will help to make faster transactions and will make the code more efficient than before. Another USP of this new version is that it will also enable moderators to verify the authenticity of the transactions without revealing their identity.
