| Summary | 0004483: Optimize refresh protocol with deterministic blinding | ||||
| Description | We could reduce the exchange's storage requirements by deterministically generating the blinding factor and new coin private keys from a seed value. At present, this is outlined in exchange/doc/papers/postquantum_melt.tex along with a discussion of the various options for doing a post-quantum refresh. | ||||

| We should coordinate making this change, as the DB structure will need to be adjusted at the same time. | |
| Resolved for libgnunetutil and exchange, minor fall-out remains to be addressed in the wallet, but at a high-level the bug is toast. | |
| Seems some crypto details need polishing ;-). | |
| Should be resolved with Jeff's latest changes. | |
| Fix committed to master branch. | |
