coindemo package

Overview

Realm coindemo is a deliberately minimal third consumer proving the extracted primitives compose: coinio handles every coin movement, feeledger handles every balance. It is an echo-vault: deposit GNOT, claim it back in full (no fees), owner sweeps out-of-band surplus.

Conservation: H == U + S (no fee pot, no app escrow), where U is the ledger's users total and S >= 0 is out-of-band surplus, recoverable only via the owner's Sweep which reserves U.

Functions

func BalanceOf(addr address) int64

BalanceOf returns addr's claimable balance.
