What is Blockchain in AWS?  

At its core, Blockchain technology can be defined as a distributed ledger which records transactions across multiple computers or nodes. It provides transparency, security, and immutability to the data stored within it. AWS Blockchain takes this technology and simplifies its implementation, making it accessible to developers and businesses.

Blockchain in AWS is a fully managed service provided by Amazon Web Services  which enables developers to build and deploy scalable Blockchain networks quickly and easily. It eliminates the need for: 

1) Manual setup

2) Manual configuration

3) Manual Management of Blockchain infrastructure 

This enables developers to focus more on application building and less on the underlying infrastructure.

How Does Amazon Managed Blockchain Work? 

The Amazon Managed Blockchain is basically a proven solution for the creation and management of highly scalable Blockchain networks with ease.  This fully managed service helps users join public networks easily. Additionally, it supports the development and management of private networks with scalability, by leveraging open-source frameworks such as Ethereum and Hyperledger Fabric. The importance of Amazon Managed Blockchain is paramount in the reduction of overheads in creating networks. It also assists in reducing overheads that are involved in joining a public Blockchain. It helps in automatic scalability for addressing the demands of applications executing millions of transactions. 

Blockchain in AWS Architecture 

Now that we know what Blockchain in AWS is, let's learn what is Blockchain in AWS Architecture and how Blockchain in AWS works. The digital chain of ledgers called Blockchain is made up of blocks that contain information about transactions. The second thing that is stored inside a block is called a hash. A hash is defined as a unique code that is generated whenever a new block has been created. The third thing stored in a block is a hash of the previous block. 

The very first block in the whole chain, that does not store the hash of any block is called the Genesis block. This looped structure is the reason behind the security and integrity provided and maintained by Blockchain technology. If anyone tries to jeopardise the data stored in any block, it will directly affect the whole chain by altering its hash. This is why Blockchain security is invincible.
