In the Web2 era, to "subscribe" meant authorizing a centralized company to automatically pull a recurring payment from your bank account or credit card in exchange for access to a service. This created a rigid, trust-based relationship where the platform dictated the terms and billing cycles for services like software, streaming, or content. The subscription was a sunk cost managed by the provider, and the user's control was limited to a often cumbersome cancellation process, with the company retaining control over the customer's financial data and access rights. In the Web3 and Fourth Industrial Revolution (4IR) paradigm, to "subscribe" is to grant a smart contract permission to stream payments in real-time from your wallet, a permission you can revoke instantly. This shifts from a "pull" to a "push" model, giving the user full control. Alternatively, subscribing can mean holding a specific token or NFT in your wallet, which acts as a verifiable key for access. This transforms the subscription from a recurring expense into a potential asset; when you no longer need access, you can sell the token on an open market, potentially recouping your cost. The act of subscribing becomes a dynamic, user-controlled, and asset-based interaction.
