Blockchain technology offers several distinct benefits for data exchange, including enhanced transparency, outstanding security, enhanced efficiency, reduced operational costs, and the ability to operate without intermediaries. This blog post will delve into blockchain’s organisation and its different layers’ functionality.

Architectural layers: 

  1. Data Layer: Blocks accumulate data securely utilising encryption. All transactions separately are digitally signed for safety, and data encryption guarantees tamper-proof information storage.
  2. Hardware Layer: Full data servers sustain safety and accessibility. A client-server and peer-to-peer network setup permits data swap among authorised nodes.
  3. Consensus Layer: All nodes within the network work together to preserve rules and guarantee transaction consistency, reducing the risk of fraud.
  4. Application Layer: This user interface allows interactions with decentralised applications (dApps) and transaction dealings.
  5. Network Layer: A peer-to-peer framework fosters legitimate transactions through rapid node communication.

Protocol layers:

Layer 0: Basis for node communication, enabling secure data swap and trustless agreement.

Layer 1: Contains prominent blockchain networks, ensuring secure transactions. 

Layer 2: Sustains scalability with off-chain resolutions. 

Layer 3: Hosts various blockchain-based applications. 

In summary, delving into the various layers of blockchain and their components, it becomes clearer how this technology operates. Blockchain is a sophisticated system that relies on the collaboration of each layer to facilitate the secure and efficient transfer of data or value between individuals. Recognising the distinct layers assists developers in crafting more advanced decentralised applications and innovating new products applicable in various domains.
