The staking yield could eventually act as a kind of benchmark rate, with some loans contracted at a rate which is a fixed spread over the staking yield rate. Determining the economic endgame for Ethereum’s Proof of Stake system is therefore difficult. Under the surface there is the pretence of a Proof of Stake system, but in reality, it barely matters, with most investors engaging with stETH. Ethereum’s Proof of Stake system could have many years left in it. The Proof of Work system may well survive longer than the Proof of Stake alternative.
