How to explore Data inside of Blockchain Network in Javascript

In this tutorial, we’re gonna build API that allows us to explore the data inside of our Blockchain Network. We will have ability to search the entire Blockchain for a specific Block by Hash, for a specific Transaction by Id. We can also fetch data from our Blockchain Network for a specific User/Address.

How to build Consensus Algorithm for Blockchain Network in Javascript

During broadcasting Transactions over our Blockchain network, a certain node may not receive a piece of information, or even there is a bad actor who sent out false information or created fraudulent transactions and broadcasts them to the whole network, convinces everybody that they are legitimate transactions. So, the Consensus Algorithm provides us a way to compare one Node to all the other Nodes inside of the network to confirm that it has the correct data. In this tutorial, we’re gonna create a Consensus Algorithm that implements the Longest Chain rule.

How to build a Decentralized Blockchain Network in Javascript

In previous post, we have a single Blockchain and the only way to access it is through API from a single server. It is centralized and not good because this API totally controls the whole Blockchain with all data inside it. Today we will build a decentralized Blockchain network that has many different instances of the API. So instead of just having our Blockchain hosted on a single centralized node, it is hosted across a decentralized network which will be very powerful because of the security: we don’t have to trust only one single entity.
