amount
→ tao_equivalent
TaoBalance TAO-equivalent of the move in RAO, the TaoBalance returned by transition_stake_internal. This is NOT the alpha that moved: the extrinsic takes alpha_amount, and that alpha leg is absent from this payload. Do not read this field as an alpha delta. The alpha actually debited and credited is visible only in the StakeRemoved / StakeAdded pair the same call emits.
