源卡字段/Source fields

字段含义
source源名(§2.2 `source` 六值之一)blockchain_com
role角色(四值闭集)comparison
judgement判据原文(逐字搬自 `criteria.json`)name: "Confirmed Transactions Per Day";unit: "Transactions";period: "day";description: "The number of daily confirmed Bitcoin transactions."(逐字取自 https://www.blockchain.com/api/charts_api 的 Response 示例)。图表页 Methodology 逐字:"Transactions from confirmed blocks are simply summed up to obtain daily numbers";Notes 逐字:"Transactions are accounted for only once they are included in a block.";API 文档逐字:"The timezone is UTC."
caliber口径(逐字搬自 `criteria.json`)实测判定:含 coinbase。依据=2026-09-15/16/17 三日该源值与本方双节点逐块复算的 M2(含 coinbase)逐日相等(818399/653862/652518),与 M3(不含 coinbase)逐日不等。日界=UTC 00:00:00(响应 x 时间戳逐日为该 UTC 日零点)。文档未声明 coinbase 是否计入——该点由本探针实测补上。
license许可(逐字搬自 `criteria.json`)未闭合。《Blockchain.com User Agreement》(最后更新 2026-08-27)正文无再分发/爬取/署名/速率条款;Section 1.1 将独立的《API Agreement》并入引用(incorporated by reference),Section 1.3 将 "our APIs" 列为 Services;Section 2.1 为 "revocable, limited, non-exclusive, non-transferable license"。**《API Agreement》正文未获取 ⇒ 转述与再发布许可无法判定**。

页型:**锚点型**(不设比值阈值;门槛 = 锚点齐备〔首末块哈希+高度区间+时点+口径指纹〕+必要性判据)|源数 0|本页 ratio = —(来源数 0 < 2 ⇒ 比值不适用 ⇒ 不构成分歧 ⇒ 走锚点型(`EP-23`))|定义:比值 ratio ≡ max(values) ÷ min(values),仅在**同指标、同日、同口径**的 ≥2 个来源之间计算;min(values) ≤ 0 时 ratio 无定义,该日不成页并登记原因。/ratio = max(values) / min(values), computed only across >=2 sources of the same metric, same day and same caliber; undefined when min(values) <= 0, in which case no page is produced for that day and the reason is logged.
