Git is not a secure blockchain. It's quite easy to rewrite history in git to change the true order of events (after all, that's the whole purpose of rebase). A true blockchain has to be protected by cryptographic signing protocols; git is not.
- darawk 8y agoA) What is your point? B) Git is perfectly secure if you don't accept pushes.
- dreamcompiler 8y agoMy point is that it cannot solve the problems a blockchain can. You could not build a digital currency on git.
- darawk 8y agoCryptocurrencies are just git + proof of work. Git, on its own, is a blockchain. Adding proof of work to a blockchain solves the timestamping problem, which allows you to use that blockchain as a currency (i.e. prevent double spends). Many times that property is useful (more than just in currencies, e.g. trading stocks), but not always, and it is not an essential property of a 'blockchain'.
