=== YUMO YUMO PRICE EPOCH v1 === # # Yumo Yumo — open price ledger # Product prices read from real receipts, published permanently. # # Publisher : Yumo Yumo Inc · https://yumoyumo.com # Sealed by : 32T9x5xGz6uaHtPnRhUhqHgJyWshbDJas7RYahEJjMjE (Solana mainnet) # One memo per epoch, no other authority: # yumoyumo:price-epoch:v1:::: # # Each observation below is identity-free: no buyer, no wallet, no receipt # id, and no time — merchant, city, date and price only. Receipt leaves are # opaque hashes; a receipt sealed with a wallet can be proven its owner's by # signing with that wallet's key, and reveals nothing to anyone else. # # Verify (needs nothing but this file and the memo above): # 1. keccak256(this file) === in the memo # 2. leaf = keccak256(utf8(line)) — the line IS the preimage # node = keccak256(concat(sort([l,r]))) — 32-byte pairs, sorted # leaves sorted ascending; an odd node is carried up unchanged # 3. fold every price-obs:v1| line + every receipt leaf # → must equal MERKLE_ROOT below and the root in the memo # # The chain proves this data was not altered. It does not prove we read # each receipt correctly: observations are validated before publication, # and whatever fails is withheld rather than published. # # When we get one wrong after publishing it, we say so here rather than # quietly. A === WITHDRAWN === section, when present, lists observations from # earlier epochs that this epoch retracts: # price-withdrawn:v1||| # is keccak256 of the published line, so you can find it in that # epoch's manifest yourself. Apply epochs in order and drop what is withdrawn; # a corrected value, where one exists, is republished here as a normal # observation. Withdrawals fold into the root below, so a retraction is sealed # as firmly as the mistake was. # # Row : price-obs:v1|||| # |||||| # |||| # kind = product | category (category = loose produce, id is a category) # discounted = 1 if the price was on offer, else 0 # Recipe : https://arweave.net/eabxr24slHrMbnZWIaKL3QiL7oitneL7y5sBHzK6EXQ # Licence : CC0-1.0 · https://creativecommons.org/publicdomain/zero/1.0/ # Public domain.
