1/ For the 10-31 test day I ran my own: 100k attestations end to end through the Traceport API. I started late, so I capped it at 6.5 hours to finish by midnight UTC.

Each got its own org-derived key, a PushDrop tx, and a verifiable merkle proof.

99,879 accepted. 1 failed.

2/ The rate was ~4.4/s, by design. That's real requests from four apps (food traceability US/FDA-FSMA, charities, multi-sector), each with its own key derivation and a treasury that refills itself while it's being spent.

Typical response: ~230 ms from request to txid.

3/ Then the chain did its thing: three reorgs (973484, 973522, 973536). One-block reorgs are normal, two miners finding a block at once. A 12-tx block beat one holding ~18k of mine; another lost to a coinbase-only block.

26,581 of my stored proofs pointed at orphaned blocks.

4/ My reorg sweep caught all three. It checks every stored proof against my own block headers service.

It also found a gap: if a tx's outputs were already spent, nothing fetched its new proof. I re-proved 12,724 overnight, each checked against my headers. Fix going in now.

5/ Final count: 99,879 of 99,879 attestations with a verified proof on the winning chain.

Reorgs are why "broadcast" can't mean "done." If you build on BSV, your app has to own its state: what's proven, against which block, and what to do when that block goes away.

6/ Thank you to @J1Pelaez for organizing, to everyone who built and broadcast that day, and to the architects of the network and the services underneath it. And of course thanks to the creator of Bitcoin! (Dr. Craig S. Wright).
