By fostering a collaborative environment, Harmony ONE aims to empower a diverse range of participants, from individual creators to larger institutions, facilitating the growth of a vibrant decentralized economy.

### How is Harmony ONE secured?

Harmony ONE uses a Proof of Stake (PoS) consensus mechanism, where validators are responsible for confirming transactions and maintaining the integrity of the network. This model allows for efficient transaction processing and scalability. Validators are selected based on the amount of ONE tokens they stake, incentivizing them to act honestly to protect their investment.

The protocol employs cryptographic techniques such as Ed25519 for authentication and data integrity, ensuring that transactions are secure and verifiable. To align participant incentives, Harmony incorporates staking rewards for validators, which are distributed based on their performance and the amount staked. Additionally, the network implements slashing penalties for malicious behavior or failure to validate transactions correctly, discouraging dishonest actions.

Further safeguards include regular audits and a governance model that allows token holders to participate in decision-making processes, enhancing the network's resilience. The diversity of client implementations also contributes to the overall security of the Harmony network, reducing the risk of vulnerabilities.
