Pure general relativity with a negative cosmological constant can in principle be a constant UV theory on its own. Following the AdS/CFT correspondence, the boundary dual should be some two dimensional CFT. Nevertheless, finding the boundary dual for this simple bulk theory remains an open problem. In this talk, I will review the status for the boundary dual of pure 3D gravity. I will discuss the interpretation of this theory in terms of an ensemble of 2d CFTs, review the successes of this approach and mention open questions. https://belgrade-strings-ipb-ac-rs.zoom.us/j/6664242666?pwd=QW5UjVWFuadA4MBhB0K6wockM1OxPZ.1&omn=97736682374 Meeting ID: 666 424 2666 Passcode: 314159
