PathDB keys diff layers by state root, not by block hash. A side-chain block can legitimately collide with an existing canonical diff layer when both blocks produce the same post-state (same parent, same coinbase, no txs). layerTree.add blindly overwrites tree.layers[root] in this case, corrupting the parent chain for any child layers already built on top of the existing one and appending a duplicate root to the lookup indices so that accountTip/storageTip resolve the wrong diff layer. Make duplicate-root inserts idempotent: a second layer with an already- present state root carries no new retrievable state, so keeping the original layer preserves the existing parent chain and avoids polluting the lookup history. |
