In the evening ACDC #180 discussed EIP-8282, which moves builder deposits and exits into separate contracts and could delay Glamsterdam by months; splitting the upgrade was mentioned as an option. The EIP-8130 change making `authenticateActor` return the full authorization surface was merged. pcaversaccio argued that Sign-In with Ethereum trains users to sign casually and creates signing fatigue. weiihann submitted EIP-8297, a partitioned binary tree.

New EIP: Partitioned Binary Tree

(weiihann), submitted; this is EIP-8297. It replaces the hexary Patricia tries with one binary tree keyed by 32 bytes, merging account and storage tries and holding contract code; account data is split into independent leaves grouped by 256 for locality; the high 4 bits of each key are a zone id for account headers, contract code or storage.
