Chaos testing on ZombieNet

The Vision

Testing Polkadot changes and releases before they go live is a multi-faceted challenge which we address by a plethora of different approaches, both automated and manual. The vision is to be able to test using an environment which is as close as possible to Kusama/Polkadot main nets. We've built and are continuously improving the core building blocks like ZombieNet as a means to get there and this is the first step that shifts our integration testing in this direction, but with reduced scope and scale. This milestone will make it possible to run long duration integration tests based on existing test cases but also include closer to real world parametrisation of the environment:

• 100 nodes in total (validators + collators)
• A mix of node versions as observed by Telemetry clustered in geographic regions (latency and packet loss perspective)
• Nodes popping in and out of the network
• Whole network upgrade of clients and runtime upgrades

The Plan

Described in the tracking issue: https://github.com/paritytech/polkadot/issues/5886

Open Questions

Currently the discussion is in the initial phase on the tracking issue, but some open questions that stand out are:

• How do we gather the required parametrisation data from the main networks ?
• Should we use test collators or actual collators from parachain teams in the ecosystem ?

Parathreads

The Vision

Parathreads are pay-as-you-go parachains: they pay for security on a block-by-block basis as opposed to leasing an entire core for a prolonged period of time.

Parathreads provide an on-ramp and off-ramp for projects, as well as the option for chains which produce blocks only occasionally. They provide another class of offering in the market for shared security which will lead to better pricing of security for longer leases as well.

The Plan

See https://github.com/paritytech/polkadot/issues/5492.

Open Questions

See considerations section in the issue above.

Asynchronous Backing

The Vision

By allowing parachain blocks to be built upon not the most recent (up to some depth K) relay-chain head, we can reduce the parachain block times to 6 seconds and allow more execution portion of a block (from 0.5 seconds to e.g. 2 seconds).

The Plan
