Using popularity of the > 'blockchain' meme to prop them up is misleading and will fire back. the difference is that blockchains are automated verifiers and reference for verification. i agree that much of the projected ideas around blockchains may be solved with common techniques. and that blockchains still need some further development. but once the proof is cheap and the transactions are fast, it scales well enough. and there will be thousand blockchains. see for instance Porsche's one blockchain per car: https://newsroom.porsche.com/en/themes/porsche-digital/porsche-blockchain-panamera-xain-technology-app-bitcoin-ethereum-data-smart-contracts-porsche-innovation-contest-14906.html Or Lenovo's Patent for paper verification: http://pdfaiw.uspto.gov/.aiw?PageNum=0&docid=20180046889&IDKey=4E2C6B937301&HomeUrl=http%3A%2F%2Fappft.uspto.gov%2Fnetacgi%2Fnph-Parser%3FSect1%3DPTO2%2526Sect2%3DHITOFF%2526u%3D%25252Fnetahtml%25252FPTO%25252Fsearch-adv.html%2526r%3D1%2526p%3D1%2526f%3DG%2526l%3D50%2526d%3DPG01%2526S1%3D20180046889.PGNR.%2526OS%3Ddn%2F20180046889%2526RS%3DDN%2F20180046889 Of course, this is still R&D. > > Every single of the enumerated mechanisms can be better executed without > blockchain.

For anything outside VM we are back to (a) and (b). There is this automated link between value administration and 'contract' execution. Imho there has nothing been like this before.
