Kyle Samani, Co-Founder and Managing Partner of Multicoin Capital, speaking at a roundtable discussion on the topic of “Why SOL Will Flip ETH” on the first day of the TOKEN2049 Main Conference, said:
Blockchain is a financial system, and on-chain transactions are the most important metric in blockchain. Over the past year, Solana has had some weeks when its on-chain transactions were higher than Ether's, and some weeks when they were lower, but today Solana and Ether are about even in terms of on-chain transactions.
In terms of total validator fees paid to Ether holders and Solana holders in their respective systems, there have been some weeks where Ether has gained more and some weeks where Solana has gained more. These metrics are essentially evenly matched right now as well.
