Bitcoin saw another one-block reorg on Sept. 11 — the third reported in about four weeks. Two valid blocks competed at height 966,500, and the network ultimately followed the branch with more accumulated work.
That does not mean Bitcoin is broken. It means one confirmation is not absolute finality.
That matters most for software. LND v0.21.0 changed channel-close handling so closes now wait 3–6 confirmations before being considered final, specifically to add reorg protection.
The practical point: finality assumptions are part of application security. If software treats the first confirmation as irreversible, a normal short reorg can become an application-level problem.
