Fine-Grained Control of Authorization

In CAP-0018 (an alternative to CAP-0016’s cosigned assets), Jonathan Jove suggests a new approach to giving asset issuers more control over their assets.

Cosigned Assets

Because Stellar is intended to be securities-friendly, some asset issuers need additional levels of control over their assets beyond authorizing asset holders. Some issuers are spinning up solutions that require them to be co-signers on asset holders’ accounts (see SEP-0008), preventing holders from maintaining full custody of other, unregulated assets. “Cosigned Assets” is a draft CAP by David Mazières that attempts to address this issue by requiring cosigning of transactions that involve a “cosigner authorized” asset without requiring the asset issuer to also be a cosigner on the holder’s account.

Their analysis indicates that 87% of accounts on the network have less than 10 lumens, and 9.76% of accounts performed 10 or more transactions in the past month.
