Sending ether will no longer always carry the same network fee, breaking one of Ethereum’s oldest rules of thumb.
Developers from the Ethereum Foundation, the nonprofit that supports and maintains Ethereum, told wallet makers, blockchain trackers, and fee calculators in a blog post to update any software built on the assumption that a basic ETH transfer costs 21,000 gas units. Gas is how Ethereum measures the work a transaction asks the network to do, and users pay for that work in ETH.
Today, that 21,000 applies whether the receiving account has been used before or not. Under Ethereum’s next major upgrade, Glamsterdam, sending to an existing account still costs 21,000, while sending to an address that has never appeared in Ethereum’s records costs more because the network has to create and permanently store a new account.
The proposal puts that extra charge at 183,600 units of a new category called state gas.
