Block Gas Target
The block gas target is the desired total gas usage for a block, acting as the equilibrium point for the base fee adjustment mechanism. Under EIP-1559, the network aims for blocks to be half-full, which is defined as the target.
If the actual gas usage of a block exceeds this target, the base fee for the next block increases. If it is below the target, the base fee decreases.
This mechanism allows the network to accommodate bursts of transaction volume while maintaining a stable long-term average cost. It provides a buffer for network spikes without requiring an immediate, drastic change in fees.
The target is a protocol-level parameter that influences the elasticity of block space. It ensures that the network remains responsive to demand while preventing permanent congestion.
Traders and developers use this metric to understand the underlying pressure on the fee market. It is a key component of the protocol physics that dictates how the network scales its throughput.
