Ethereum warns fake builders could disrupt Sepolia test ahead of Glamsterdam upgrade on Oct 6

Ethereum developers confirmed the public test of the Glamsterdam upgrade on Oct. 6 using the Sepolia testnet but warned that attackers could exploit free test ether and disposable builder identities to win block auctions and withhold transaction payloads. This attack would not affect mainnet funds but could disrupt critical infrastructure testing before the upgrade goes live on Ethereum's mainnet. The Glamsterdam upgrade aims to increase block capacity and improve gas pricing, supporting more transactions per block. Developers also noted a shortened review period for client teams before the Sepolia fork and have tentatively scheduled the next public test on the Hoodi testnet for Oct. 27, with mainnet activation still unscheduled.

Ethereum developers' warning about the upcoming Glamsterdam test is presented here with Pluang's market data as of Sep 18, 2026 12:31 WIB. Among 50 major cryptocurrencies priced on Pluang, 46 rose and 3 fell today. Notable movers include AAVE at Rp2.368.716 with an 8.72% increase, AXS at Rp17.786 up 8.59%, and ADA at Rp3.777 rising 8.29%.
