Blockchain CBSA – Blockchain 101 Part 5

Comparing enterprise blockchains Enterprise blockchain. So let’s go ahead and talk about enterprise blockchains. Now, the exam itself is really going to focus on three blockchains. The main blockchain is going to focus on is Ethereum, hyper, ledger and Bitcoin. Let’s just clarify, Bitcoin is not an enterprise anything, it’s a cryptocurrency, right? So it’s not a blockchain, it doesn’t support smart contracts, at least from a wide scale perspective. There’s a way to run them, but it’s not going to be efficient by any means. But that’s another story…

Objective – Consensus among Blockchains Let’s go ahead and talk about consensus. Now, when it comes to consensus, this is a course area that will be tested, I guess, in a way probably significantly more than perhaps other sections.
