The Glamsterdam upgrade will increase Ethereum's throughput to 10,000 transactions per second by the end of 2026.
"Glamsterdam. Scheduled for the first half of 2026, this upgrade is huge. It introduces something called EPBS or enshrined proposer builder separation which yes does sound a bit like Gwennneth Paltro's next divorce but simply put it makes the network more decentralized and censorship resistant. It also aims to increase throughput towards 10,000 transactions per second by the end of the year."
