CoreJam #31

Closed gavofyork closed 7 months ago

gavofyork commented 10 months ago

This is a proposal to fundamentally alter the workload done on the Polkadot Relay-chain, both in terms of that which is done "on-chain", i.e. by all Relay Chain Validators (Validators) as well as that which is done "in-core", i.e. distributed among subsets of the Validators (Validator Groups). The target is to create a model which closely matches the underlying technical architecture and is both generic and permissionlessly extensible.

In the proposed model, code is stored on-chain with two entry-points. Workloads are collated and processed in-core (and thus parallelized) using one entry-point, whereas the refined outputs of this processing are gathered together and an on-chain state-machine progressed according to the other.

While somewhat reminiscent of the Map-Reduce paradigm, a comprehensive analogy cannot be taken: the in-core processing code does not transform a set of inputs, but is rather used to refine entirely arbitrary input data collected by some third-party. Instead, and in accordance, we term it Collect-Refine-Join-Accumulate.

As the prototype takes shape, a large number of the details RFC have changed. I'll close for new while I author a new spec to be discussed once the prototype is completed.
