# What QMS Offers

### Quantum Miners

QMS is designed so that quantum hardware can join its miner network, bringing greater computational power and better solutions to the clients who pay for them. 

This is achieved by combining two ingredients:

* A PoUW consensus protocol, where miners find solutions to optimization problems that commercial clients actively pay to solve, e.g., logistics scheduling, portfolio optimization.
* Optimization problems that quantum hardware is natively designed to tackle, e.g., Quadratic Unconstrained Binary Optimization (QUBO) problems.

PoUW alone is already a revolution in tokenomics, giving miners a second source of income on top of block rewards. As quantum hardware matures and joins the network, the network's computational capacity grows further, amplifying this effect.

### Proof-of-Useful-Work

As the name suggests, PoUW consists in replacing the hashing of Bitcoin with work that not only secures the blockchain, but creates extra value by finding solutions to real problems. On the QMS Network, problems are proposed by clients. They also lock funds into a smart contract to pay the miners that find good solutions. The miners run a solver, prove that they have done the work, produce blocks, and earn the corresponding block rewards. The best solutions found in the process claim the client payment.

From the miner perspective, this multiplies earnings. They are not only paid by the blockchain and its users for ordering and executing transactions, but also by clients for the solutions they find. Two revenue streams from a single computation.

From the user perspective, they get the security of a PoW chain at reduced cost, since client payments also support the cost of mining.

From the client perspective, they have access to a decentralized supercomputer at a competitive price.

From the investor perspective, they hold the tokens of the only PoW chain that redirects the energy spent toward solving problems for paying clients. The tokenomics are optimized to extract every bit of value from the work, without losing on chain security.

### Post-Quantum Security

QMS is designed around a hybrid model for the execution layer. Initially, users open accounts with standard elliptic curve signatures for ease of use and compatibility with major wallets. In subsequent protocol updates, security-conscious users will be able to upgrade their accounts to PQ signatures, after which funds can only be transferred with a PQ signature. Because QMS is designed from a clean slate, this migration can be completed significantly faster than for incumbent networks.

As Q-Day approaches, non-PQ accounts will be frozen, preventing funds from being stolen. Legitimate users can recover their funds by providing a zero-knowledge proof that they know the seed from which their secret key was derived. This protects against quantum attacks: even though quantum computers can compute the secret key from the public key, they cannot compute the seed from the secret key.

### EVM Compatibility

While QMS is writing a brand new consensus layer for the quantum era, the execution layer is taken largely unchanged from Ethereum. Existing wallets, block explorers, and developer tooling are compatible from launch, and smart contracts can be migrated with no code changes.
