What are Blockchain Layers and How Do They Work?

What are Blockchain Layers?

On a blockchain, due to the lack of a centralized controlling body, all transactions are strictly protected and data safely kept on a distributed ledger that everyone can access and verify. Such a distributed ledger system follows a predetermined protocol, requiring a “consensus” to be reached by numerous computers (or nodes) in the network to validate transactional data. Each node continuously adds, examines, and modifies new entries.

Blockchains offer this unique technique of transaction authentication through the use of a layered architecture. There are five stages of play, and each has its own set of responsibilities. The blockchain layers explained below.

Each network participant in the dispersed network of a blockchain architecture layers maintains, approves, and updates new entries. The structure of blockchain architecture layers is represented by a set of blocks with transactions listed in a particular sequence. The blockchain architecture layers might be public, private, or consortiumbased.
