One line adds up Rootstock's own peg events. The other ignores Rootstock entirely and asks Bitcoin what the federation addresses hold, reconstructed from every transaction touching all fifteen of them. Two routes to one number is the point: where they diverge, something is being missed, and the gap is more informative than either line alone.
The event line starts in May 2020, not at genesis. Before block 2,395,450 the Bridge logged no peg activity, and while some peg-ins from that era are recoverable by replay, the peg-outs are not recorded anywhere — 282.82 BTC left the federation in 24 transactions that Rootstock never logged. Summing from zero therefore overstated the balance by that amount for ever after. The line is anchored instead to the Bitcoin-measured balance at the week the events begin, so what is drawn is only what is measurable.
Latest: 1019.69 BTC in the week of 2 Nov 2026. 799 weekly observations.
