Block Elasticity

Block elasticity refers to the ability of a blockchain to dynamically adjust its block size or capacity to accommodate varying levels of network demand. By allowing blocks to grow or shrink within defined parameters, the network can manage temporary spikes in transaction volume without immediate fee volatility.

This design allows for a target block size while providing flexibility to handle bursty traffic. When demand is low, the network shrinks the block size toward the target; when demand is high, it expands to provide more throughput.

This concept is vital for maintaining a balance between decentralization, which requires manageable block sizes, and performance, which requires high throughput. It is a key component of modern consensus efficiency.
