-
B.
The Merge
The Merge was Ethereum’s landmark transition from proof-of-work to proof-of-stake consensus, fundamentally altering its security model, energy usage, and ETH issuance dynamics.
-
C.
Ethereum hard fork
An Ethereum hard fork is a backward-incompatible upgrade to the Ethereum blockchain protocol that creates a permanent divergence in the network’s transaction history and rules.
-
D.
Ethereum consensus layer
The Ethereum consensus layer is the part of the Ethereum protocol that coordinates validators and block production to securely agree on the canonical blockchain state.
-
E.
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.
