Lost keys have already cost billions of dollars, many more at risk — Polygon exec By Cointelegraph

While private or mnemonic keys offer many advantages for security, they also present practical challenges, according to Mudit Gupta, the chief information security officer of layer-2 scaling solution Polygon.

Speaking at the Community Conference (EthCC) event on July 17, Gupta discussed the differences between theoretical security and practical security in the blockchain and crypto space. Gupta told the EthCC audience in Paris that when it comes to theoretical security, the space is “running so fast.” However, the Polygon executive believes that when it comes to practical security, the space is “so far behind.”
