# HeLa Consensus Node The **HeLa Consensus Node** is powered by **Tendermint Core**, a proven Byzantine Fault Tolerant (BFT) consensus engine that is widely recognized for its robustness and reliability. Within the HeLa architecture, the Consensus Node forms the backbone of the **consensus layer**, ensuring both the security and integrity of the network. A Consensus Node is responsible for: * **Validating transactions** submitted to the network. * **Participating in consensus** to agree on the ordering of blocks across all active nodes. * **Maintaining immutability and accuracy** of transaction history. By leveraging Tendermint Core, HeLa ensures: * **Fast and deterministic finality** of transactions. * **Resilience against Byzantine faults**, enabling the system to function correctly even in the presence of malicious or faulty actors. * **High stability and predictable performance**, critical for supporting both developers and end-users. As HeLa continues to evolve, additional details and specifications regarding Consensus Node operation and its utilization of Tendermint Core will be shared. These enhancements are aimed at further strengthening the HeLa blockchain ecosystem. Stay connected for upcoming updates and advancements as we refine the consensus infrastructure powering HeLa Chain. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
