Scalability in Alterium is achieved through off-chain transaction processing. By moving most of the computational work off the main chain and using advanced Layer 2 protocols, Alterium is capable of handling a much higher volume of transactions per second (TPS) compared to traditional Layer 1 blockchains.

The utilization of State Channels and Optimistic Rollups plays a critical role in this. State Channels allow for multiple transactions to be bundled into a single on-chain operation, while Optimistic Rollups perform computations off-chain but keep transaction data on-chain, allowing for an improved transaction capacity.

By balancing on-chain and off-chain operations, Alterium ensures that the blockchain network remains scalable, fast, and efficient, even as the number of users and transactions grows.
