During his speech at the Ethereum Community Conference (EthCC), Mudit Gupta, the chief information security officer of Polygon, shed light on the practical challenges associated with private or mnemonic keys despite their security advantages.
Gupta emphasized the disparity between theoretical and practical security within the blockchain and crypto space.
While the industry is rapidly progressing in terms of theoretical security, Gupta believes it lags significantly behind in practical security.
He specifically highlighted the difficulties of safeguarding private keys compared to passwords. Private keys, once leaked, cannot be changed, unlike passwords.
Gupta explained that the responsibility of keeping a mnemonic or private key safe poses a far more challenging problem.
The consequences of failing to secure mnemonic keys are significant, with billions of dollars already lost due to individuals misplacing or losing their keys.
Gupta stressed the urgency of addressing this issue, as countless users’ wallets contain billions of dollars that are improperly secured.
Gupta acknowledged that private keys are theoretically 100% secure, as long as they remain unknown to others.

However, he recognized practical challenges that can arise, such as ensuring access to funds for loved ones in the event of the owner’s death or dealing with compromised keys.
Furthermore, Gupta discussed the inherent difficulties faced by defenders in the security realm. He pointed out that attackers have an easier time than defenders since they only need to exploit a single vulnerability.
Defenders, on the other hand, must cover every possible entry point, leaving no room for any oversight.
Despite these challenges, Gupta emphasized the importance of defending against cyber threats.
He acknowledged that security professionals have a tougher role compared to hackers and exploiters, as defenders must diligently cover all bases to ensure the integrity of systems.
In conclusion, Mudit Gupta highlighted the practical challenges surrounding private or mnemonic keys, even though they offer enhanced security.
He called for greater attention to securing mnemonic keys, considering the billions of dollars at risk due to improper security measures.
Additionally, Gupta emphasized the arduous task faced by defenders, who must safeguard every aspect of a system against attackers seeking vulnerabilities.
