So recently I've heard about David Chaum's eCash. Which is weird because that was a thing in the 1990s. His company DigiCash went for a few years and then filed bankruptcy. Back then, the byzantine generals problem hadn't been worked out and we didn't have blockchain technology, so the double-spend problem was solved by the bank (yes, a bank) keeping a ledger. Also unlike bitcoin, it provided privacy, it was untraceable.

So I'm presuming the ideas are coming back in order to provide untraceability to bitcoin?

Yes, still requires a custodian, but I think nostr:npub12rv5lskctqxxs2c8rf2zlzc7xx3qpvzs3w4etgemauy9thegr43sf485vg has pointed out in the past that the other big problem with ecash was always that there was no agreed upon unit of account. Bitcoin solves that so that we can have private custodial ecash denominated in a unit that all parties can agree on.
