There are perhaps hundreds of thousands of videos “explaining” how Blockchain works.  I picked this one in particular because it talks about what I think is going to be the critical issue: security of the blockchain and who provides secure blockchains.

1) If blockchains might have security issues with programming or crypto-cracking the algorithms that make them work, who could be involved to make sure this does not happen?

2) What sort of companies might legitimately and usefully provide secure blockchain technology?
