I think the greatest barrier here is in verifying the real world house price at exit on the blockchain. I, as an investor, would have to trust someone to verify this for me. At which point it may as well not be on the blockchain.
Also, verifying any of the following on the blockchain:
- whether an exit has taken place
- whether the person claiming to own a house actually owns it
- whether the house even exists
- anything concerning the real world, really
"Not just any blockchain-based ledger, however, will suffice. For one, electronic corporate records must be capable of being converted into legible paper form within a reasonable time. Second, like all other Delaware stock ledgers, a blockchain ledger must be able to (i) be used to prepare a list of stockholders entitled to vote, (ii) record information required by the DGCL to be maintained in the ledger and (iii) record transfers of stock pursuant to Article 8 of the Delaware Uniform Commercial Code."
So a blockchain or distributed ledger technology can be used, but it could just as easily be done using a relational database or paper records.
