Between the pools

Every crossing between the transparent world and a shielded pool, and between one pool and another, is public by construction: the amounts are in the clear even when the endpoints are not. What follows is all of them for the last day, the balances they add up to, and the share of the supply whose soundness nobody can prove either way.

source to destination, last 24 hours. 84 percent of it is the Orchard to Ironwood migration. Orchard shows zero inflow by consensus: ZIP 2006 makes it exit-only.

balances now - CipherScan at 3,456,227, which is also the height the content stats seed carries. The site's rendered chain tip is 3,456,854 and the research dossier was taken at 3,456,938; a balance is quoted at the height it was read.

Pool balances at height 3,456,227, with the consensus rule that governs each.

Sprout rests on the BCTV14 construction whose key generation emitted the bypass elements found in 2018 (CVE-2019-7167), and Orchard on the circuit that carried the 2026 counterfeiting bug. Neither balance can be proven free of counterfeit value. That is not a claim that either contains any.

A pool born at zero has small trees, and early anchors bound small sets. Plotted, not asserted: this is the distribution of what the anchor bound permits, not of what anyone has resolved.

What this page does not claim

the residual is a bound, not an accusation

The unprovable residual is a statement about verification, not about behaviour. Sprout's soundness rested on the BCTV14 construction, whose key generation emitted the bypass elements found in 2018 (CVE-2019-7167), and Orchard's on the circuit that carried the 2026 counterfeiting bug; neither balance can be proven free of counterfeit value, and neither is claimed to contain any. Nobody has shown that a single counterfeit note exists in either. The number is here because the honest answer to "is the supply sound" is "95.67 percent of it is provably so", and rounding that to yes would be the same move this site spends the rest of its pages objecting to.

The migration lens counts denominations and never attributes one. A canonical amount is a property of ZIP 318, not a fingerprint of a wallet: every wallet migrating the same balance emits the same denomination run, which is what makes the ladder a privacy feature rather than a leak. The distribution is plotted because the shape of a day is worth seeing. No row of it belongs to anyone.
