Vibhu Norby of the Solana Foundation has issued a challenge to the XRP community for a public debate focused on on-chain activity data. Norby highlights significant differences in network activity, noting that Solana boasts 2.5 million daily active accounts compared to XRP's 25,000 over the past three years. Additionally, Solana processes approximately 100 million daily transactions, vastly outpacing XRP's 1 to 1.5 million.
