The Ethereum Dencun upgrade was activated at block height 8626176, marking Ethereum's move towards a more secure and efficient blockchain network. The upgrade includes 9 EIPs, of which EIP-4844 has received the most attention, which can improve the staking experience and cost efficiency. The benefit areas include Layer 2, staking, storage and DA. The TVL of Ethereum Layer 2 has reached 38.98 billion US dollars, with an increase of approximately 11.08% in the past 7 days. Projects that have not issued coins have also attracted much attention. Proposals EIP-7044 and 7045 will improve the exit mechanism and security risks caused by the increasing scale of staking, and proposal EIP-7514 will reduce the burden. The Dencun upgrade introduces temporary data storage capacity to stimulate demand for the DA layer. Projects on the RaaS track include Altlayer, Caldera, Conduit, etc., providing users with friendly tools and services to integrate and deploy Rollup solutions.
