The Chicago Sun-Times will test a "social paywall" Feb. 1. To access the site, "readers will be prompted to donate Bitcoins to or Tweet about the Taproot Foundation," a group that says it "makes business talent available to organizations working to improve society."

Sun-Times Editor-in-Chief and Publisher Jim Kirk said the Sun-Times is the "first major USA newspaper to test a Bitcoin-based paywall." The Dish Daily implemented a paywall built by the same company, BitWall, last year.

The Sun-Times erected a more traditional metered paywall in 2011.
