Ethereum Fixes Potential Glamsterdam Upgrade Flaw to Prevent Misallocation of Staked ETH
Summary
- Ethereum developers said they fixed the possibility that staked Ether (ETH) could be misallocated during the Glamsterdam upgrade.
- The flaw could have caused both deposits to be credited to a block builder account if that account and a validator deposit overlapped under a specific public key.
- Developers applied a rule that sorts pending deposits by withdrawal credentials so validator deposits are properly credited to validator accounts.
Forecast Trend Report by Period
Ethereum developers have fixed a potential flaw in the Glamsterdam upgrade that could have incorrectly assigned staked Ether to a block builder account.
Odaily, a digital-asset news outlet, reported on October 27 that Ethereum developer George Avsetsin found an issue under draft rules in which both deposits could be credited to a block builder account if a specific public key was first registered as a block builder and a validator deposit was later made using the same key.
Avsetsin described it as a code-level issue that could arise under certain conditions, not an actual attack case. Existing review procedures can prevent such an attack, and no related losses have been reported so far.
Developers also revised the rules to sort pending deposits by withdrawal credentials, ensuring validator deposits are credited to validator accounts as intended.
