Blockchain implementation

It depends on the objective of the Blockchain that you want to start up. Also, it depends on if you want to have an open or a private Blockchain.

• If you want to start up a private Blockchain, i.e. the acces to the Blockchain is controled and the data isn't open, I suggest you to start reading about Hyperledger Fabric.
• On the other hand, if you want to start up a public Blockchain, i.e. everyone would acces to the Blockchain and the would be open, I suggest you to start reading about Ethereum.

If you give more information about your idea, we could help you. Like Carcigenicate said, your question is too broad.

watch this tutorial, there is also the code to try it.

You can try exploring Ethereum and NEM for your purposes. The reason mainly is because a lot of financial institutions (startups to enterprise levels) are already either using or experimenting with them with great success.

If you want to create your own Blockchain implementation, try out either BigchainDB (https://www.bigchaindb.com/) or multichain (https://www.multichain.com). Both are open source platforms for creating your own blockchain implementation.

To understand Blockchain just start with some Basic Theory but do more Practicals Here i am Share some of Links that will help you a lot :: -> Decentralised Application by Siraj Rawal Intro to Decentralized Apps

-> Decentralised Application Book by Siraj Rawal Decentralized Applications: Harnessing Bitcoin's Blockchain Technology

-> Also use some Block Chain Demo Application so that you can understand the working and concepts which is working behind the System - Blockchain Demo

-> The Most Part is to Understand the IPFS (InterPlanetary File System) it is the backbone of entire Blockchain.
