Adam B. Levine’s post on the topic of DRM and content access:
One concept we’re working on at Tokenly is the idea of Token Controlled Access (TCA), or Token Controlled Viewpoint (TCV), as I prefer to think of it. What you see in a given application, or on a given website, varies depending on what access tokens you possess.
We’re building a generic service that will let you create an account and associate a bitcoin wallet with it. You prove to the service that you control the wallet by signing a transaction or making a .0001 BTC send to an address shown only to you. This proves that you control the private key, which means you control the account, and the tokens it contains are yours.
In the future, the service will let applications and websites request information about your verified public addresses — we call them pockets — either generally, or ask yes/no questions to confirm or disprove balances a user indicates it possesses in a private pocket.
