The first type of Blockchain Layer is the Architecture Layer, which is composed of 5 sub-layers: the hardware layer, the data layer, the network layer, the consensus layer, and the application layer. Read more to learn how these layers work.The hardware layer is the first layer of blockchain architecture. As the foundation of blockchain technology, the hardware layer provides the physical infrastructure for the blockchain network.
This consensus layer consists of the algorithms and protocols for multiple nodes to reach a consensus on new blocks and additions to the blockchain. All nodes validating the transaction must be in agreement to declare that the transaction is valid.can vary across blockchains, such as with Bitcoin’s Proof-of-Work consensus mechanism or Ethereum’s Proof-of-Stake method.
Both Proof-of-Work and Proof-of-Stake systems are capable of running dApps, thanks to smart contracts on the application layer. Networks like Ethereum, Polkadot, and Cardano are great examples of platforms that have an application layer that developers use to build their own dApps.The second way to understand blockchain technology is by knowing the different layers of blockchain protocols. The blockchain network comprises four layers: Layer 0, Layer 1, Layer 2, and Layer 3.
