Shale

With Shale, SPs are monetizing(e.g., earning FIL) their computing devices (CPU/RAM/GPU servers) by leasing the computing resource together with their sealed data.

Shale is targeting on native high-performance computing such as AI/ML training/inference, usually against large/open datasets. Any traditional tasks are possible, such as C/C++ compiling, short-time web serving, general data-processing etc..

The idea is sending programs around to where the data locate (i.e. the data center of SP), and utilizing those Filecoin+ deals by disk mouting.

Programs here refer to off-chain native executables like C/C++, CUDA, TensorFlow.

SSH-payment-tunnel

Just like normal SSH, but equipped with a local cryptographic payment tunnel, which accumulates fractional payments and aggregates them to ZK proofs in the end. The ZK proofs will be posted to Shale layer-2 by SPs.

Both parties could terminate the lease anytime.

The design is to accommodate future plugins for in-place monitoring/benchmark of session quality to catch potential cheating behaviors.

Shale Layer-2 Marketplace

There will be smart contracts on FVM for coordinating orders between clients and SPs, where:

Clients create orders with their SSH pub-keys, prices, time and resource requirements SPs accept orders, confirming by clients with collateral SPs upload payment-tunnel ZKPs to claim rewards Clients post ratings/reviews based on their time/usage. High-performance native computing Programs are running natively in container with access to local accelerators (GPU).

All traditional web1/web2 software ecosystems (unix, apt-get, gcc, python, nodejs, etc.) become available, thanks to container technology.

Examples: C/C++ compiling, ML training/inference, general data pipeline/processing, short-time serving etc..

Implementation

The first implementation is a terminal command-line tool (CLI) that focused on demonstrating the using experiences, which includes:

Client lists SPs with available datasets Client sends request to particular SP SP spawns docker containers on server with required accelerators(e.g., GPUs) SP auto-provisions SSH server and client's pub-key inside container Mock SSH-payment-tunnel UI Client runs a ML training task remotely in the container
