The virtual mempool is Arkade’s offchain execution layer, a dynamic coordination environment for Bitcoin-native applications. It powers real-time transaction flows that:
  • Emulate Bitcoin’s UTXO model through Virtual Transaction Outputs (VTXOs)
  • Execute in parallel without global state bottlenecks
  • Let users control when (and if) to anchor to the Bitcoin blockchain (“dynamic settlement”)
Arkade’s execution layer is designed for scale. Transactions form a directed acyclic graph (DAG) that enables independent branches to execute simultaneously. Execution is instant, and settlement is batched onchain.
