It is the production-ready version of the network, where real transactions and smart contracts are executed. The Mainnet is where all the blockchain transactions are processed, and it is the network that runs 24/7, providing users with access to various features, including smart contract execution, cryptocurrency transfers, and more. The Mainnet operates on a decentralized system, which means that all nodes on the network work together to validate transactions and maintain the integrity of the blockchain. The Mainnet is also designed to be scalable, meaning it can handle a large volume of transactions and grow with the needs of the network. The EXA\_Blockchain Mainnet uses a Proof of Authority (PoA) consensus mechanism, which relies on trusted validators to verify transactions and secure the network. This makes the Mainnet more efficient and faster than other consensus mechanisms, which require a large number of nodes to reach consensus. In summary, EXA\_Blockchain Mainnet is the production-ready version of the EXA\_Tech blockchain network, where real transactions and smart contracts are executed. It is designed to be scalable, decentralized, and secure, providing users with access to various features and services on the network.
