I'm in agreement with Tom on a lot of this, but land title is one of the examples I use for why blockchain is superficially relevant, but actually not of much use. Back when land titles were, at law, dependent on evidence of a sufficiently long series of successive transactions, a chain of electronic transactions would have reflected the real world of land title. Torrens Title was invented in South Australia in 1858, and much of the world has adopted it: https://en.wikipedia.org/wiki/Torrens_title The key point about Torrens Title is that the legal authority is a register entry, and hence the chain is of no more than historical interest. So (remnant 'old system title' arrangements aside), the blockchain model has no more relevance to land titles than it has to share-trading. _________________ >"NSW Land Registry to trial blockchain for conveyancing: The state wants to >transition completely to eConveyancing by July 1, 2019:", Asha McLean, zdnet, >October 15, 2018: >https://www.zdnet.com/article/nsw-land-registry-to-trial-blockchain-for-conveyancing/ > >I am on the ACS Blockchain Technical Committee and have attended a few >meetings with Data 61 who are preparing a report on it for ACS.
