-
C.
The DAO hack
The DAO hack was a 2016 exploit of a major Ethereum-based investment fund smart contract that led to the theft of millions of ether and ultimately prompted a controversial hard fork of the Ethereum blockchain.
-
D.
EIP-1559
EIP-1559 is an Ethereum protocol upgrade that restructured transaction fees by introducing a base fee that is burned and a separate tip to miners, aiming to make fees more predictable and reduce ETH supply inflation.
-
E.
