With the implementation of the Dencun Upgrade in Cancun, EIP-4844 will further reduce data costs for L2/L3. This is a huge benefit for XAI. Lower costs mean increased profit margins, or in other words, a further reduction in user barriers. We are on the eve of an L3 technology explosion, and today's XAI is like broadband technology during the dial-up internet era. Once it becomes widespread, applications will explode.
