Zcash Supply Check

Checks the no-counterfeiting arithmetic of the Zcash chain value pools from the balances you paste in: recomputes the four-pool sum in integer zatoshi, checks every pool is non-negative (a negative pool balance is an invalid chain state under the pinned consensus rules), and tests the pools' sum against the claimed total supply, reporting any difference exactly, in zatoshi, with its sign. It checks arithmetic only: this tool cannot read the Zcash chain and does not verify that the pasted numbers are true of any chain at any height, and it does not verify the claimed issuance total itself. Values only: non-numeric fields, unknown pool names, missing pools, fractional zatoshi, and over-bound values are refused, never echoed or zeroed.
