The comparisons of SRHC-TD and the RHCs.
| Storage method | The whole chain | The seed |
| Initialization | Computation | SRHC < SUHC < RHC < SRHC-TD | SRHC < SUHC < RHC < SRHC-TD | Communication | SRHC-TD = RHC = SRHC = SUHC | SRHC-TD = RHC = SRHC = SUHC |
| Publication and verification and recombination | Computation | SRHC-TD < RHC < SRHC < SUHC | SRHC-TD < RHC < SRHC < SUHC | Communication | SRHC-TD = SRHC < RHC = SUHC | SRHC-TD = SRHC < RHC = SUHC |
