Blockchain Layers Explained
Blockchain technology is a decentralized digital ledger that records transactions across multiple computers.
This technology is the backbone of cryptocurrencies like Bitcoin and Ethereum but has many other potential uses.
One way to understand the different types of blockchains is to divide them into layers.
The first layer of blockchain technology is the underlying network or protocol. This layer is responsible for maintaining the integrity and security of the Blockchain. It is the foundation upon which all other layers are built.
The most popular protocols are Bitcoin and Ethereum.
The second layer of blockchain technology is the application layer. This layer is where users interact with the Blockchain. It is where smart contracts, decentralized applications (dApps), and other blockchain-based services are built.
The most popular dApps are built on the Ethereum blockchain, but many others exist.
The third layer of blockchain technology is the data layer. This layer is where data is stored on the Blockchain. It is where users can store and retrieve data, such as documents, images, and videos.
The InterPlanetary File System (IPFS) is the most popular data layer.
The fourth layer of blockchain technology is the governance layer. This layer is where users can vote on changes to the Blockchain and make decisions about the direction of the network. It is where users can propose and vote on new features or improvements.
The most popular governance layer is the Decentralized Autonomous Organization (DAO), but many others exist.

In summary, Blockchain technology is divided into four layers: the underlying network or protocol, the application layer, the data layer and the governance layer.
Each layer serves a different purpose and enables additional functionality, but they all work together to create a secure, decentralized network.?
Understanding these layers can help you better understand the potential of blockchain technology and how it can be used in various industries.
