QANplatform is a quantum-resistant hybrid blockchain platform enables developers and enterprises to rapidly switch to QANplatform or build software applications and run business processes on blockchain by providing a powerful software toolkit. The QAN blockchain platform toolkit includes: open-source code, private and public blockchain, easy setup, fast deployment, simple migration, multi-language development, online developer academy, community support, fast data transactions, low hardware and energy cost, quantum computing resistant security

QARK is an ERC-20 Ethereum utility token, an essential part of QAN's platform, with the following functions:

Generic smart contract developers get QARK after their code is being reused by the Specific Smart Contract Developers.

All developers pay for their smart contract deployment in QARK.

Specific smart contract developers pay a fraction of the full price as a license fee to the Generic Smart Contract Developers in QARK.

Validator pays a deposit fee in QARK to enter the pool of validators who have the right to validate the following block.

Full node providers get a reward in QARK for giving access to their storage for the blocks to be validated (tokens generated by the network), in proportion to the storage actually used by the blocks. 

Smart contract users pay for transaction fees. Fees are fixed in FIAT, long term predictable. (All operations which modify data require payment of a transaction fee.)
