Under Null, no vote among many validators decides the weights any more; exactly one validator does, namely the one with the largest stake. At the same time the number of slots per subnet rises from 256 to as many as 2,500.
For holders of TAO this is no footnote from a developer channel. Anyone delegating their tokens to a validator receives their dividend on a different calculation. And anyone wanting to enter a subnet as a miner no longer needs TAO to do it under certain conditions. The price stands at $273.87 on Monday, October 19, 2026, or 244.29 euros, which is 7.3 percent below the level of a week ago.
