Three ways to value an instrument
A rebasing instrument names its price source; a par instrument has none; an accumulating one is priced by its reserve, from its assets’ own price sources.
Backed instruments
A backed instrument is minted against deposits of eligible assets into a reserve on the ledger, which the venue, the issuer and the reserve’s own holder sign. The assets can be any registrar’s, the issuer’s own or another’s. See Backed issuance for the reserve, its terms, and the rule it keeps. Every mint and every redemption checks, inside its own transaction, that the reserve still covers what is outstanding (Σ units × price × (1 − haircut) ≥ outstanding × backed price × minimum cover); a settlement that would break it fails, and nothing moves.Reference structures
What changes with configuration, and what needs new software
A new version of the shared software is a vetting event: each party’s node approves the new package itself before acting on it. A new asset is never one.
An instrument’s display is off the ledger: its name, symbol and display decimals are the venue’s record, shown beside its id and never settled on. Ids may be opaque, since the registry’s operator reads every configuration.
