>Why don't we have a proof of custody (chain of ownership)
In the USA and most developed countries, we already do have a "proof of a chain of ownership". And, we've had it for hundreds of years. For example, the title deeds and transfer of title documents saved at the county courthouse.
The issue is whether the so-called "proof" is : authentic or forged, and/or conflicting with other prior claims. (E.g, is the title transfer document faked? Are the signatures from the real owners? Was the previous person who transferred the title the actual rightful owner?)
Ultimately, "proof" of ownership is a social consensus that sorts out the claims and converges on agreement of who owns what. (I made a previous comment about this.[1])
You might notice that "proof" is recursive: if we "prove" that the "proof" was valid, how do we know that proof is valid? Well, things like "title insurance" and/or a court case with a judge/jury to render a final judgement is the process to break that infinite cycle of "proof of proofs".

- dingaling 8y agoIn the UK the banks and property agencies are moving away from title deeds in a process called 'dematerialisation' My deeds, dating back to 1949, no longer exist. They were shredded by Nationwide. I have a certified copy but they are considered of academic interest and 'proof of ownership' is now recorded by a database row. Which is terrifying, as a simple clerical error or a system failure could ruin so many lives.

- chii 8y agoPaper, if recognised legally means you have the responsibility to hold and present it as proof. You could keep the paper in a safety deposit. You can make certified copies. If proof is electronic, you have no recourse if computer error causes a dispute, since you do not hold any proof yourself to present as evidence!

- eagsalazar2 8y agoDigital + govt agencies... high likelihood of screw ups. I still think blockchain makes sense here. Distributed verifiable record that doesn't depend on any single entity to do things right or be honest. That is a perfect fit for bc.
