# Runtime side for PoV Reclaim ## Implementation Overview - Hostfunction to fetch the storage proof size has been added to the PVF. It uses the size tracking recorder that was introduced in my previous PR. - Mechanisms to use the reclaim HostFunction have been introduced. - 1. A SignedExtension that checks the node-reported proof size before and after application of an extrinsic. Then it reclaims the difference. - 2. A manual helper to make reclaiming easier when manual interaction is required, for example in `on_idle` or other hooks. - In order to utilize the manual reclaiming, I modified `WeightMeter` to support the reduction of consumed weight, at least for storage proof size. ## How to use To enable the general functionality for a parachain: 1. Add the SignedExtension to your parachain runtime. 2. Provide the HostFunction to the node 3. Enable proof recording during block import ## TODO - [x] PRDoc --------- Co-authored-by: Dmitry Markin <dmitry@markin.tech> Co-authored-by: Davide Galassi <davxy@datawok.net> Co-authored-by: Bastian Köcher <git@kchr.de>
Substrate Cumulus Parachain Template
A new Cumulus-based Substrate node, ready for hacking ☁️..
This project is originally a fork of the Substrate Node Template modified to include dependencies required for registering this node as a parathread or parachain to a relay chain.
The stand-alone version of this template is hosted on the Substrate Devhub Parachain Template for each release of Polkadot. It is generated directly to the upstream Parachain Template in Cumulus at each release branch using the Substrate Template Generator.
👉 Learn more about parachains here, and parathreads here.
🧙 Learn about how to use this template and run your own parachain testnet for it in the Devhub Cumulus Tutorial.
