Ethereum sets a great example when it comes to security. For all the auditing and internal reviews they do, they still put $2,000,000 up for grabs in a Sherlock audit contest. And their approach was completely vindicated. 4 Highs were found in the contest!! These weren't Highs in clients that control 1% of the network. In order to meet the criteria for High, it has to slash, bring down, or split >33% of the network. And 4 of these vulnerabilities were found in the contest. Credit to Ethereum for going the extra mile with a $2,000,000 audit contest. Contests are still the gold standard for security🏅
