Ethereum, the second largest blockchain by market capitalization, has implemented various initiatives to strengthen its security and scalability. Among the most notable is the Ethereum Improvement Proposal (EIP) 3074, designed to enhance the experience and security of transactions through signature delegation. Additionally, the network has adopted mechanisms such as Proof of Stake (PoS) following 'The Merge', reducing energy consumption and mitigating 51% attack risks.
Another key initiative is the Ethereum Bug Bounty Program, which incentivizes developers to identify vulnerabilities in the protocol. According to the Ethereum Foundation, this program has been instrumental in detecting critical flaws before they can be exploited.
However, challenges persist. Vulnerable smart contracts remain an issue, with millions in losses due to exploits such as those occurring in DeFi protocols. To address this, projects like Ethereum 2.0 (now part of the main network) aim to improve efficiency and security through sharding and solution layers like Rollups.
In conclusion, Ethereum continues to advance in security, but requires a multifaceted approach that combines technical updates, rigorous audits, and education for developers. Its evolution will be crucial for maintaining trust in Web3.
