All these companies/ICOs adopting 'Blockchain' doesnt mean a damn thing unless you have decentralized hash power behind its generation (security). Otherwise you just have a shitty database
While I mostly agree, there are some benefits to using a blockchain. If the SEC mandated companies publish block hashes they would be unable to edit transaction history.
Consensus and PoW are a large part of immutability and future trust (ala 51% attack).
Great point that is often missed. Anyone can chain blocks of data together. PoW is what makes this unique, trustworthy, and immutable.
and when you mention that, they start kvetching.
