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.

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.

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!!!!

[@hanibaltesfamichael5936]

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

[@aditikulkarni-moghe6542]

Very nice example with all cases thank you

[@deanmindock3680]

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

[@mdmonzurmorshed3557]

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

[@PrieyudhaAkaditaS]

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

[@salawujonathan6722]

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

[@rosalsaini4352]

Great explanation sir🙏👍

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

Great work! Very clear in explanations

[@abidinberkay1]

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.

[@americancitizen748]

Awesome.

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?

[@deanmindock3680]

Create a class Node and then elaborate it, is my 1st thought.

[@chaaandkd]

Brilliant

[@MEmCe-gq2xj]

very good introduction, thank you

[@Mr_Oszy]

How can I run this code in cloudsim?

[@MrSaravanan009]

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

[@igormelo2446]

I think so.

[@oluwatomibombata8834]

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

[@MrYass24]

This statement has no logic since blockchain is a design pattern that can be implemented using any language not just javascript

[@kristinacassandratolentino7238]

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

[@igormelo2446]

You talk about the algorithm or the calculate of the transactions itself?

[@kristinacassandratolentino7238]

The calculate of the transaction

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

[@user-bc9nn1be1d]

Epic

[@aronwiza8412]

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

[@shadsluiter]

"...we are going to write some computer code to demonstrate how blockchain works". It is an academic exercise.

[@robysoriano2956]

Base from my observation, Block Chain is like LinkedList hahaha

[@deanmindock3680]

Yeah, it is very similar except for the use of hashed links.
