Eligius, September 2012: the body of 197883 and the headers of 197701 and 197705 #18

Description

@deadmanoz

Summary

Three Eligius blocks from September 2012 are listed in data/reported-blocks.jsonl as reported coinbase overpayments that the dataset cannot establish. Luke Dashjr reported them in #bitcoin-dev on 9 September 2012 together with 197438, which is an admitted record. The pool's own block list, captured on 18 September 2012, carries all three hashes marked stale.

What is known:

  • 197883 (000000000000011e6d02f6063d4a797ce42fe1f97ecf3dd640b8145f12c2304d): the header is recovered and meets its target. Merged-mined child blocks on Namecoin, Ixcoin, I0coin and Devcoin preserve its coinbase, 47 outputs paying 50.0005 BTC, and a Merkle branch with exactly one sibling, so the block held two transactions. The sibling's txid is 002a6ddf7bc76472bba263f4c5eea26c3ab978b9879b44ecb50421afd3d23956. Its bytes, and so its fee, are missing, and without the fee the overpayment stays a report.
  • 197701 (00000000000003414be07bc5e700b1b2168ceb7259b4b9de4b583c435ebc03f2) and 197705 (0000000000000607179812c7bc8751fb834436bdb79f1ab6239d34b4f8cd2dda): known only by hash.

Admission needs the complete body of each block. A header alone for 197701 or 197705 would fix its identity but could not establish the overpayment.

What has been searched

The same sibling txid appears next to the coinbase in 274 merged-mining records across 219 distinct Bitcoin parent headers between 14:41 and 20:57 UTC on 8 September 2012, so the pool kept the commitment across many templates, but no child chain preserves the transaction itself. Neither 197701 nor 197705 appears in the Namecoin, Ixcoin, I0coin or Devcoin blocks of the period. Current nodes and the mempool.space, Blockstream and blockchain.info APIs return nothing for the three hashes or the txid, and the Wayback Machine holds no explorer page for them. The Eloipool source of 1 September 2012 has a fee accounting path that could produce an overpayment, but that is a possible mechanism, not evidence of the block's contents.

If you ran a node, a pool or an explorer in September 2012 and kept block or transaction data, a body for any of these hashes, or the transaction above, would settle it.
