  "notes": "BIP 1 (\"BIP Purpose and Guidelines\") is the document defining the Bitcoin Improvement Proposal process. Its header in the official bitcoin/bips repository states 'Created: 2011-08-19', and the Bitcoin wiki page for BIP 0001 corroborates this creation date. Therefore the four-digit calendar year is 2011. This is an off-chain historical fact (evidence: panel); the pinned Ethereum chain/block window is used only as a timestamp for the request, not as the source of the answer."
