chains

on solana the machine is one anchor program and one coin. the program accepts shares, keeps the anchor mirror, keeps the commitment and output accounts, keeps the tree, and holds the rung. it has no instruction that moves coins or sol except the reward buy, which is a cpi into the curve from the buffer.

the program's name shows on explorers because its idl is published on chain with the deploy, and the deploy is a verified build so the source hash matches the executable. the links above resolve to the program and its state account.

zcash is the even side. the machine receives orchard notes at a unified address and never spends them. the full viewing key is published so the notes can be listed by anyone with a view only wallet. the anchors the program mirrors are the orchard tree roots zcash itself publishes in its block headers.

a zcash fill is grade 1 by the direct route and grade 3 by the two hop route. its share proves a merkle path from the note commitment to a mirrored anchor, which is the same proof a zcash spend would make, minus the spend.

monero is the odd side. the machine receives outputs at a primary address and never spends them. the view key is published so incoming outputs can be listed by anyone with a view only wallet. the key images are never produced, so the outputs are provably unspent for as long as the machine exists.

a monero fill is grade 2 by the direct route and grade 3 by the two hop route. its share proves the output's global index and transaction hash after ten confirmations, which is monero's own unlock depth.
