By the time its chips were to be embedded into Internet of Things (IoT) devices, 21 projected its cost to produce 1 BTC could be as low as $7.45.
The documents suggest 21 had been considering a multi-pronged strategy to build out a competitive mining network that also sought to reimagine the transaction confirmation process as a way to onboard consumers.
Without a strong core of industrial bitcoin mining facilities, the document contended, consumer mining with the chips would have been too unprofitable to attract interest.
The documents projected that, should the BitSplit chips seek to process transactions alone, a user would need 34,722 days, or about 93 years, to discover a block. By pooling its resources, however, 21 projected it could reduce the average block time to 200 minutes, or roughly three hours, paying users 0.72 mBTC or about 17 cents per day.
As part of this effort, 21 would also seek to make the activity of mining more user-friendly by auto-enrolling users into its own social network. Named BlockParty, the project was introduced via a visual mock-up of how the social network might look running as a mobile application.
According to the image text, users could keep track of BTC earned daily and view the purchasing habits of friends. In the example, one user is able to use his BTC to skip 15 minutes of commercials on online video service Hulu.
Other updates show friends activating and deactivating devices.
Internet of Value
Once consumers and businesses are set up to receive bitcoin via everyday devices, the documents provide evidence 21 had built technology that intends to serve as the template for how such earnings could be used in microtransactions on the Internet.
In particular, 21 had been working on a process that would allow developers to block users from accessing websites unless funds are sent to a bitcoin address. Notably, the process used the 402 Payment Required error code originally intended for web-based micropayments at the outset of the World Wide Web.
Under this scenario, a client would ask a server to open a connection, and rather than seeing an error when denied, the user would receive a price quote in BTC.
Paid APIs, paid Wi-Fi, priority email and ad-free web browsing, 21 had suggested, were all additional use cases that could be enabled once consumers are able to generate small amounts of bitcoin through its mining products.
