Detailed five major layered architecture of the block chain!

Because the block chains eliminate the existence of the central management institution, all transactions must be strongly protected, and the data must be safely stored on a distributed book. Distributed Base Technology (DLT) Working on the preset protocol, various computers (or nodes) on the network reach a “consensus” to verify transaction data. Each node is added, checked, and updated when an entry appears.

The block chain has a hierarchical architecture to facilitate this unique transaction authentication. It involves five layers, each layer has its own different functions. Let us understand the role of architecture and each layer.

Hardware infrastructure layer

The block chain data is securely stored in the data server. When we browse the web or use any block chain app, our machine will request access to these data from the server. Framework for promoting this data exchange is called a client-server architecture. The block chain is a point-to-point (P2P) network, allowing the client to connect to the “point-to-point”, which is faster and easier to share data. It is just a huge device network that communicates with each other and requests data with each other. This is the way of creating distributed books. Each device that communicates with another device on the network is a node. Each node is randomly verified the transaction data.

2. Data layer

The block chain is just a “block” that contains transaction data. When a node verifies a certain number of transactions, the data is bundled into a “block”, added to the block chain, and links with the previous data block. “Chuangli” is the first block in the chain, so it does not need to link any previous block. Instead, the subsequent block is linked to the creation block and the process will be repeated each time you add a new block. This is the formation and continuous development of the block chain. Each transaction uses the private key of the sender’s wallet to “digital signature”. Only senders can access this key, ensuring that the data will not be accessed or tampered with anyone else. This is called “finality” in the block chain terms. Digital signatures can also protect the identity of the owner, which is encrypted, which ensures maximum security.

3. Network layer

The P2P framework enables all nodes to exchange transaction data to reach a consensus on the effectiveness of the transaction. This means that each node must be able to discover other nodes on the network for fast communication. It is the network layer to promote this “node communication”. Due to the node discovery, block creation and block additions are also managed by this layer, and therefore also referred to as “propagation layers.”

4. Consensus

This is the most critical layer in block chain operation. This layer is responsible for verifying the transaction, without it, the entire system will fail. This layer runs requires a certain number of nodes to verify the protocol of a transaction. Therefore, each transaction is processed by multiple nodes, and then these nodes must reach the same result and agree on their validity. The frame maintains the deposition properties of the block chain, as no node can separately control any transaction data, and the role is distributed. This is called a consensus mechanism. Because there are so many nodes to process transactions, they are bundled and they are added to the block chain, so multiple blocks may be created at the same time, thereby forming a branch in the block chain. However, there must always be a single block to add, and the consensus layer also ensures resolution of this conflict.

5. Application layer

This is a layer that runs intelligent contracts and decentralized applications (DAPP). Intelligent contracts make decisions based on certain triggers, such as contracts, realization of spot prices. The action following these decisions is performed by DAPP, and all this happens at the application layer. DAPP also promotes communication between user equipment and block chains. Therefore, the application is like facing the user’s front end, while the main zipper chain is a rear end, and the data is securely stored therein.
