最新报道:Despite over 150 existing Ethereum layer 2 networks, companies like Robinhood continue launching their own due to lower costs and ecosystem integration advantages compared to building independent layer 1 blockchains. While centralized layer 2s offer control over pricing and access, they must purchase Ethereum mainnet transaction space, though expenses remain low—exemplified by Base’s $50,000 settlement fees against $4.9 million revenue in June. Despite debates over fee fairness, layer 2’s economic appeal remains strong even with potential future increases.
