* Lightweight
Compatible with the self-interests of each peer, or ability to select the best neighbors
* Robust against adversarial actions: A Catena peer does not need all details about a candidate neighbor to decide whether to connect Incentivizes peers to relay blocks promptly.
* Naturally adaptive to varying hash-power
Catena is the next generation of blockchain protocol designed to enable legacy, current, and future blockchains to scale and communicate seamlessly. Catena offers a wide variety of possibilities in the blockchain space due to its sharding, interoperability, and central algorithm.

By providing a fair and secure platform, Catena allows users to regain control over their personal information. The project offers a scalable network featuring functionalities that bypass current blockchain limitations. CORE intends to provide an environment-friendly system that is sustainable, interoperable and provides enhanced throughput. 

**Highlights**
Network Efficiency – Catena contains an AI model at the core of its blockchain. This AI Model speeds up the network’s collective transaction processing times and also enables the network to operate under attacks or faults. 
Security – The AI model helps coordinate the nodes on the network while also strengthening security on the Catena blockchain. This is accomplished through the network’s outlier detection protocol, which monitors for unusual behavior. The AI randomly selects nodes to test and gather data, monitoring network activity outside of the norm. In this phase, any corrupt nodes will be identified. 

**Transaction Privacy Protection Layer**: Catena transaction privacy protection layer (TPPL) adds an extra layer of security and privacy when transacting on its blockchain. This universal layer is applied to every CORE-connected chain and can be applied to the major public blockchains.

**Randomness** – The Catena network combines Verifiable Random Function (VRF) and Verifiable Delay Function (VDF) into a single hybrid solution, thus achieving true Randomness within the network. Randomness influences the difficulty in the mining function of PoW blockchains and periodically chooses the validators in a PoS blockchain.

**Scalability** – To address the scalability issue of Practical Byzantine Fault Tolerance, Catena enhanced the consensus mechanism by reducing the communication complexity within standard PBFT implementations to create the Accelerated Practical Byzantine Fault Tolerance (APBFT) consensus mechanism.

CMCX Coin Usage
Through the CMCX token, users can conduct transactions on the Catena blockchain and pay for all utility fees within the ecosystem. Platform users can use the token to participate in governance, stake, transactions, smart contracts, and reward validators.

Catena’s mission is to serve the community. Users can vote for management and developer teams using the native token (CMCX). The Catena community provides projects funding. Users will vote on any proposed changes to the blockchain or platform, creating a community-driven blockchain.
Through Catena, all blockchains, past and present, will be able to scale and communicate seamlessly with one another by utilizing the CMCX token. 

**Advantages**
Extensive research & value proposition to current blockchain limitations: The Whitepaper available on the Multi-chain website provides an in-depth yet accessible presentation of the responses provided by the team to solve current limitations on scalability, network efficiency, overall security, and reward fairness.

**Security audits available**: An audit of the network performed by CERTIK is currently public on the CORE Multi-Chain website. This research documents the project’s performance in the following criteria: Security, Runtime, Documentation, Testing, General, and Transparency.
