币界网报道：Several major Ethereum validators, including Coinbase, Lido, and Kraken, are participating in a testnet experiment to evaluate potential bottlenecks in the network's block processing capacity. The test, conducted on the Holešky testnet, aims to simulate high transaction loads by increasing the number of attestations—votes confirming block validity—to stress-test the network. This initiative follows concerns raised by Ethereum core developers about the growing volume of attestations potentially slowing down block processing. The experiment will help assess whether current infrastructure can handle future scaling demands, particularly as Ethereum continues to grow in adoption. Results from the test could inform future protocol optimizations to maintain network efficiency.
