(T)he best way to really wrap your head around a scheme like bitcoin is to really suspend belief for a bit and get exposed to all these relevant details. What are some general advantages to using. And the way we basically handle and reduce the risk of double spending is through a specific set of nodes in this peer to peer network who are known as Bitcoin miners, okay. Let's say as a ledger item you could think of a transaction block as representing let's say an entire page in a ledger book, okay. And again, there is this proof of work that I mention that is used work from home meeting planner jobs to kind of determine or identify what the what work was involved in coming up with a transaction Blockchain, okay. That may be a term that you've heard if you have had any interest in Bitcoin recently. So, there's going to be some level of continuity.

Bitcoin : What is it?

What do you think about the move by Khan Academy to accept Bitcoin Cash donations? Coding in my Sleep blog. But it's basically an incentive for other nodes in the Bitcoin network to help Alice in essentially validating some of the details of this transaction for Bob, okay. He'll probably send the check some part of the transaction. And the idea is that Bitcoin then becomes more of us is pseudonymous protocol where people are addressed by their pseudonyms and that provides some level of privacy to users who want to transact using the Bitcoin system, okay.

The bitcoin scheme is fairly involved, he explains. And these Bitcoin miners will also include in this block. Thus creating a closed loop virtuous cycle.

And by Alice's identity again I mean her identity within the Bitcoin system. Bitcoin Digital signatures, in the overview video, Ramzan focuses on the details of how a single transaction works, rather than attempting to summarize the workings of the overall bitcoin system. Zulfikar is a world-leading expert in computer security khan academy bitcoin and cryptography and is currently the Chief Scientist at Sourcefire.

And my plan for this first video in this series is to describe some of those mechanics at a high level. Perry added, While there are admittedly bigger stories to be found in the bitcoin world right now, as an education reformer,r and long-time fan of the good work Khan Academy is doing, I have to say this has me pretty excited. She might decide that she wants to give let's say 30 of these Bitcoins over to Bob.

The new Khan Academy titles include: Bitcoin Overview, bitcoin The money supply, bitcoin Transaction block chains. And we'll talk about what a transaction fee means a little later and I think I'll also dive into it in future videos. And then Bitcoin miners will also include a specially crafted sequence of numbers associated with these transactions. One BCH supporter, for example, is selling his Tesla and a diamond ring for Bitcoin Cash only, with BCH supporters campaigning and promoting its use as a currency.

And by cryptocurrency I mean that we use a lot of cryptographic techniques in order to facilitate or to really enable Bitcoin transactions to take place. You ultimately have what you can think of as a chain of transactions and you can call this a transaction blockchain, okay. And then once the newly broadcast chain gets kind of verified and meets the right properties and nodes on the network are just going to go ahead and start using it and there are sort of pending new transaction blocks to that chain, okay.
