# Scalability of POW+A and Liquidity Control of DGC

The DGC Coin, a mining reward, is expected to be used as the main value standard in the POW+A mainnet. The value of the mainnet coin is determined from two perspectives: utilization and incineration amount. Utilization refers to the development of the Dapp based on POW+A. POW+A mainnet will open various platform services to activate the DApp. POW+A-based token users will receive a service that allows them to swap their tokens with DGC Coins through the Smart Contract authorized by the POW+A Foundation. POW+A-based tokens can swap with DGC Coin, the mainnet coin, because it supports the factoring service for payment methods.

The structure, in which the mainnet coin grafted with the factoring and the POW+A-based token are swapped, generates GAS for the POW+A Smart Contract; it is operated for the token's issuance, distribution, and swap. Like the Ethereum structure, the POW+A mainnet will also constantly control liquidity by the blockchain itself.
