What was the plan that purposed one house legilature?

The plan proposing a one-house legislature is often referred to as the "unicameral legislature" concept, which gained attention during the debates of the U.S. Constitutional Convention in 1787. It suggested that a single legislative body would simplify the lawmaking process, reduce government costs, and enhance accountability. The idea was championed by figures like Thomas Paine and later influenced some states, such as Nebraska, which adopted a unicameral system. However, the U.S. ultimately established a bicameral legislature with the House of Representatives and the Senate.
