A trillion-dollar crypto market is represented by thousands of projects and platforms, covering many use cases. The problem which prevents crypto to break out into the mainstream is that platforms are mostly non-interoperable. The Quant platform is an experiment in creating global networks connected to the blockchain. Its main tool is the Overledger network comprised of tunnels and bridges that run with the Overledger OS. With this operating system, developers can not only build bridges but also multi-chain apps ("mDApps") on this platform.
The native utility token QNT is taken for a license fee to deploy a mDApp or bridge on the Overledger network. Therefore, users who want to use the Overledger bridges are charged QNT to use them. At the time of writing, Overledger supports Ethereum, Qtum, and Hyperledger. QNT in particular is an ERC20 token and is not supported by other blockchains.
