Substrate Consensus Layer refers to a framework that helps blockchains agree on the state of the network without needing a central authority. It is part of the Substrate framework developed by Parity Technologies, designed to build custom blockchains on the Polkadot network.At its core, the Consensus Layer manages how transactions are validated and added to the blockchain. It uses various consensus mechanisms that ensure all participants, or nodes, have the same view of the blockchain’s history and current state.By employing this layer, developers can focus on building specific features for their blockchain while relying on the Consensus Layer to handle the complexities of agreement among nodes. This flexibility allows for the integration of diverse consensus algorithms, enabling different blockchains to customize their behavior based on their unique needs.Overall, the Substrate Consensus Layer plays a crucial role in maintaining decentralization, security, and scalability, ensuring that transactions are confirmed in a way that all participants can trust.
