Program a Blockchain example with Java code example

Blockchain in Java. Create a blockchain of transactions in Java in just 15 minutes using hashing techniques to ensure a secure chain of events. Blockchain uses hashing algorithms similar to encryption techniques used in password security. The blockchain approach takes hashing to the next step by linking blocks in a series to make transactions in the chain of blocks secure and preventing fraud through a distributed ledger. This takes security away from a central authority and places security in the realm of peer to peer crowdsourced security.

This video is amazing. I’m writing an essay in computer science for my finals about a topic of my choice. Of course I chose blockchain as I find it incredibly fascinating. This video literally eliminates a huge amount of research I would have had to do… thank you for that!!!!

[hanibaltesfamichael]

This a very great example of blockchain. I literally didn't have any idea about blockchain and I am a beginner in computer science. So Thank you

[deanmindock]

Very well done. My Java is rusty, but was able to follow along. Presently just a hodler of 14 cryptos.

[AmanKumar-mrgo]

Thank you very much. I love to iron the basics before I can go fancy about some topic. It explains the basic so well. Kudos to your effort, simple and effective.

[MrSaravanan]

Could we say, it is similar to linked list structure?

[aditikulkarni-moghe]

Very nice example with all cases thank you

Working on a project where I need to simulate nodes on a network creating blocks on a blockchain, like 2 thousand nodes, and test the "network" with say 10 or 20 transactions per second, thinking of instantiating objects of a "node" class for the nodes, but how to I simulate all this?

[tedesco]

Very good explanation. How to use common blockchain with Java in simple steps?

[PrieyudhaAkaditaS]

Amazing explanation! Thanks!
But how other computers validate this block of chain? Do you have video for that too?

[abidinberkay]

nice video but just a small critic if you care; zooming in/out to screen is so frequent. sometimes im getting tired or loosing attention due to zooming every 5-10 seconds.

[kristinacassandratolentino]

how about the result of transaction in every block? in the second block shadgiveitaway then how to change the value in every transaction?

[salawujonathan]

Hi, thank you very much for this invaluable video. I'm working on a project for sharing textual data on the blockchain (possibly with interplanetary file system IPFS). How do I go about it after watching your video? Thanks

[mdmonzurmorshed]

It is really a very nice example. Thank you. Can you show an small java code example of Consensus algorithm on this program?

[lassewierowski]

This Video is so Amazing! Thanks a lot

What do you say to people who suggest that JavaScript is much suitable for constructing blockchains as compared to JAVA?

[chessmaster]

A basketball player can do a slam dunk. So hash sounds like making it a 10000 story building. Something that no one can reach

[aronwiza]

You can, of course, try and write your own blockchain, but why? There is already a multifunctional blockchain ecosystem Utopia

[massimilianovitale]

Great work! Very clear in explanations

[robysoriano]

Base from my observation, Block Chain is like LinkedList hahaha

[chessmaster]

I thought I was learning how to mint money
