Ethereum co-founder Vitalik Buterin has announced plans for four significant upgrades to the Ethereum network in response to criticisms of its "chronic death." These upgrades aim to enhance the system's performance and scalability. Since the Ethereum Merge, the network's circulating supply has increased by over 950,000 ETH, with an annualized inflation rate of approximately 0.23%. In a separate incident, IoTeX has suffered a $4.3 million loss due to a suspected private key leak. The company has detected suspicious activity in its token vault and is actively tracking and freezing the hacker's assets to mitigate further losses.
