pub const ROOT_TAG: u8 = 0x4;Expand description
Stream root: H(ROOT_TAG ++ leaf_count[8, LE] ++ bag(peaks)[32]) (mmr::MmrRoot::from_bag).
Binding the count stops a peer from presenting the same peaks at a forged position. The empty
MMR has no peaks to bag; its root is the count-0 case, with a zero bag (mmr::empty_root).
