A Compute node executes WASM executables which are uploaded and stored in Swarm and registered in a Work Order registry, for non-recurrent work orders, and a Jobs registry, for recurring work orders.
A node sole responsibility is to compute data or datasets stored in Swarm or any IPLD-compatible store, eg Filecoin, IPFS. Because it only understand how to execute WASM, any Beeson Query Language usage is done internally in the context of the WASM Engine.

Summary
A Compute node executes WASM executables which are uploaded and stored in Swarm and registered in a
Work Orderregistry, for non-recurrent work orders, and aJobsregistry, for recurring work orders.A node sole responsibility is to compute data or datasets stored in
Swarmor any IPLD-compatible store, egFilecoin,IPFS. Because it only understand how to execute WASM, any Beeson Query Language usage is done internally in the context of the WASM Engine.Guide-level explanation
WASM
A node implements both
EIP-3668and EIP-5559: Cross Chain Write Deferral Protocol to accept storage tasks, executes them and update its state to a blockchain.There are two types of nodes as described in Swarm DB - Indexing and computing,
indexingandcomputenodes.We defined a combination of WASM blocks, one being the WASM Engine and another the WASM Runnable orchestrator:
A node can be any P2P client, thus we might have a compute node inside a web browser and an indexing node in a cell phone.
Additionally, a set of smart contracts are required that uses the above EIPs specifications.
