For blockchain, Layer-0 is a root layer that allows for cross-chain interoperability between Layer-1 protocols. In other words, it is a connector of blockchains.
When it comes to blockchains, one of the major issues they face is scalability. The benefit of Layer-0 is that it has several use cases in scalability and can set up individual reward structures, data validation, and digital currency wrapping. With Layer-0, operators deploy networks quickly and across several nodes without needing to directly communicate with the underlying protocols of existing blockchains; they can do it outside of them and still work effectively.
The backbone of a blockchain comprises miners, connections, and hardware. Layer-0 works as a network framework under the blockchain, validating data based on user-defined functions and setting up a series of state channels. It supports several systems, such as Cosmos and Polkadot, in addition to multiple consensus algorithms like Proof of Work (PoW), Proof of Stake (PoS), Proof of Reputable Observations (PRO), Proof of Activity (PoA), and Directed Acyclic Graphs (DAGs).
Layer-0 projects are incredibly useful, as they can benefit blockchain encryption in three significant areas — neutrality, scalability, and adaptability. They typically have a native token as its core consensus layer, which gives users economic incentives to contribute and uphold an ecosystem.
