var AtomicGasLimit *big.Int = big.NewInt(100_000)

The atomic gas limit specifies the maximum amount of gas that can be consumed by the atomic transactions included in a block and is enforced as of ApricotPhase5. Prior to ApricotPhase5, a block included a single atomic transaction. As of ApricotPhase5, each block can include a set of atomic transactions where the cumulative atomic gas consumed is capped by the atomic gas limit, similar to the block gas limit.

This value must always remain <= MaxUint64.
