The high cost and limitations of network resources on EOS make it so that it is very expensive for dApp developers to store data in the form of RAM on the EOS blockchain. The requirement of having to store both dApp smart contracts and their state information, such as the balance for each user, permanently in RAM is presenting a barrier to dApp scalability. The vRAM System proposed by LiquidApps offers a decentralized alternative memory solution.
The DAPP Network is a protocol introduced into the EOS blockchain to complement it and help EOS dApps to scale. The DAPP Network is not a separate blockchain instead it is a protocol built on top of the EOS blockchain to complement it. DSPs (DAPP Service Providers) are incentivized through inflation rewards to create and offer services on the network, in the same way Block Producers get rewarded in EOS tokens. The LiquidApps team itself has built services for the DAPP Network such as vRAM, LiquidAccounts, Zeus SDK, LiquidOracles, and LiquidLink.
