Cube is a virtual machine designed to enable bridgeless smart contract execution natively on Bitcoin. Providing a fully trustless execution environment with unilateral exit, Cube keeps users in full control of their funds.

By combining virtual UTXOs with a symmetric state channel architecture and leveraging Bitcoin DA, Cube integrates Bitcoin payments directly into a virtual machine with global-state.

Cube is currently in the early development phase.
