Abstract

This EIP introduces a new Merkle tree shape for Simple Serialize (SSZ) types that results in fewer hashes when only a small number of leaves is used. The new tree shape grows progressively with increased leaf count and no longer has a bounded capacity. It also offers forward compatibility: a given chunk index is always assigned the same stable generalized index (gindex) regardless of leaf count…
