INTMAX is the first stateless zkRollup, which shifts data availability (DA) and computation to the client side, providing extreme scalability and privacy to Ethereum. In addition to this, the stateless architecture allows for the democratization of block generation and interoperability. This could signify the beginning of truly convenient decentralized payments.

On a more profound level, the INTMAX algorithm introduces several features that were previously unthinkable in zkRollups

• Block producers remain unaware of the contents of each transaction or its validity.
• The cost of data availability is 4~6 bytes per transaction, and a large number of token transfers can be made in one transaction without additional DA (Data Availability) costs.
• An invalid transaction can become valid later through deposits.
• Both data storage and ZKP computations get to O(1) on user-side.
• Subscription payments are available.
