| 2780 | Reduce intrinsic transaction gas | Matt Garnett (@lightclient)> | https://ethereum-magicians.org/t/eip-2780-reduce-intrinsic-cost-of-transactions/4413 | Draft | Standards Track | Core | 2020-07-11 |
Abstract
Reduce the intrinsic cost of a transaction to 16,360 gas.
Motivation
The current 21,000 gas intrinsic cost of a transaction does not accurately
represent the true cost of the transaction.
Specification
After block.number >= FORK_BLOCK, enforce an intrinsic gas cost of 16,360.
Rationale
The EVM-equivalent of transaction validation would consist mostly of ~110 bytes
of data and 2 x SLOAD (0x54), 2 x SSTORE (0x55), and an ECRECOVER. This
translates to (16 * 110) + 2 * 800 + 2 * 5,000 (assuming account is initialized) + 3000 = 16,360. This implies that the current intrinsic cost of
a transaction is overpriced by 4,640 gas. Since validation is implemented
natively, it's possible that this is a conservative estimate.

Security Considerations
Increased transactions-per-block
Reducing the intrinsic gas of transaction will lead to an increase of transactions per block. This has several consequences:
-
Historically, periods of high transaction counts has correlated with higher-than-average uncle blocks being mined. It must be determined that the new intrinsic cost
16,360will not adversely affect. -
The state size of Ethereum continues to grow at an unsustainable pace. Increased the transaction throughput will exasperate this problem.
Storage may be accessed more than once
It is difficult to arrive at a fixed-cost for the intrinsic transaction fee, because it's possible for clients to need to revalidate a transaction in its mempool. This can be caused artificially by submitting a chain of transactions and bumping the gas price of the first transaction by minimal step sizes. Since the first transaction is now a "new" transaction, the transactions that follow sequentially will need to ensure the account's balance can still afford to transact.
