An interesting tie-in to the space is that cash is memoryless whereas Bitcoin has memory - the ownership of every transaction output that has ever been owned is permanently preserved.
I had been wondering if anyone was using memory palaces for seed phrases. It makes sense that they would be but I hadn't heard anyone talk about it.
On the other hand, some more complex technical bounties lay dormant for many years and then when someone tried to claim them, it was hard to get paid out. Perhaps X Prize style grants from larger organizations would be more trustworthy for folks to expend resources trying to claim.
Bounties should be time locked in some kind of multisig escrow like transaction. I know I wouldn't work on a bounty that I wasn't intrinsically motivated to contribute to unless it had credibly committed to paying out.
Development of DIDs has been ongoing for several years; adoption has seemed pretty slow. There is a bit of a network bootstrapping issue with this type of technology - you preferably want everyone on the same standard, but it's tough to get early adopters since you don't know which platform will end up taking most of the market share.
It'd probably be easier to start with a centralized ID and decentralize it (in terms of bootstrapping the network) than start with a decentralized UX and forking/updating limitations.
