ETH is the sole medium with which blockspace can be purchased within the Ehtereum network (i.e., the only medium in which transaction fees are paid).

ETH is the sole medium with which blockspace can be purchased within the Ehtereum network (i.e., the only medium in which transaction fees are paid).
[1] = ƒ(blockspaceDemand, feeMarketPressure)
blockspaceDemand
— measurement of the computational resources required to process transactions (directly tied to ETH's exchange utility)feeMarketPressure
— an abstract reflection of the competitive dynamics of transaction fee bidding (a direct value transfer mechanism)Since EIP1559 has been accepted, Ethereum has implemented partial fee burning: fees are subdivided into base fees and additional priority fees, with the former being burnt. This generates a consistent guaranteed upward deflationary pressure on the value of ETH.
[21] = ƒ(token_extant, token_burnt, token_generated)
token_extant
— the amount of ETH in existencetoken_burnt
— the amount of ETH burnt in a given timeframetoken_generated
— the amount of ETH minted in a given timeframeEthereum's PoS consensus protocol requires that every validator stake at least 32 ETH. These tokens are not only exposed to possible unmitigated depreciation due to a required immobilisation period, but are also alienable in case of malfeasance by the validator.
[7] = ƒ(staking_period, amount_staked, price_at_staking)
staking_period
— the duration of the lock-up periodamount_staked
— the amount of tokens locked up by the userprice_at_staking
— the price of the locked token position at the moment of locking; defines the locked value together with the lockedOnce a validator is included in the active set by staking a sufficient amount of ETH, he must also participate in the consensus, both to avoid being slashed (i.e., penalised in terms of partial stake alienation) and to qualify for remuneration.
[8] = binary
Reflects rewards earned by validators. When a validator performs his duties correctly, he is eligible to receive a number of rewards:
[22] = ƒ([8], priority_fee_income, consensus_reward_parameters, MEV)
priority_fee_income
— the variable priority fee income of a validatorMEV
— validator income due to MEVconsensus_reward_parameters
— the parameters of the consensus reward emissions
