Im wondering about function isChainValid because it secures all blocks except of the last one. So lets try to change data nad hash in savjee.chain[2].data and savjee.chain[2].hash.. you will receive TRUE in this case. Or maybe I missed something? or.. maybe somehow its not needed to check in real cryptocurrency mechanism?
I assume that every block should only be the previousHash of one other one, right? So in a real world example, the addBlock would have to be synchronised to run atomic. I mean I know JS is more or less single threaded, but in the real world this code would run distributed even, not just multi threaded.
Thanks Brother….you have pushed me in right direction. I was reading, watching many videos on Block Chain, but your Javascript example cleared lot of ideas. Thanks again. May I tell you, I have used many a times timestamp & date to create a unique ID for various databases. That concept has been expanded into something massive. Great work….
Good job. Very well explained.
Buy my shitcoin guys 😉
can you make a tutorial adding the proof of elapsed time consensus to it?
I get this error: TypeError: Cannot read property 'hash' of undefined . Does anybody know how to solve it?
how do you open the terminal
why mine didnt work but yours did
How to hosted these things on everyone computers, I mean how to create a decentralized network?
what npm did you install to download crypto-js? mine keep sending me an error message.

This is an awesome explanation 👌
Perfectly explained. The miracle of simplicity. Thank you.
lol the comments on this video all seem made by bots
I understand correctly that the hash of the new block can be parsed and get the date of the old block?
what is the name of code editor you use?

Thanks bro..nice explanation.
Wonderful explanation. Thank for this video. which platform is used to write the code?
coff coff hyped linked list… i say Blockchain..

Hi Savjee, i'm totally new to coding. when i open up my terminal it shows the powershell and my file directory terminal is it correct?
After +1 year of courses, projects documentation and tutorials I could finally understand how Javascript classes work thanks to this video. Thanks!
just awesome, i planning to implement in go, but awesome explanation.
Gold
you sound just like GreatScott
Im having an issue where my genesis block does not have a hash therfore validation fails, any idea?
error: Require is not defined
When I go to the vs cod terminal and type,"npm install –save crypto-js" it says there is no command with the name "npm".
I like java but I am learning G code its a hybrid codeing language to make my blockchain
