This is the first PR in preparation for https://github.com/paritytech/polkadot-sdk/issues/454. ## Follow ups: - https://github.com/paritytech/polkadot-sdk/pull/3904. - https://github.com/paritytech/polkadot-sdk/pull/3905. Overall changes are documented here (lot more visual 😍): https://hackmd.io/@ak0n/454-np-governance [Maybe followup](https://github.com/paritytech/polkadot-sdk/issues/4217) with migration of storage item `VirtualStakers` as a bool or enum in `Ledger`. ## Context We want to achieve a way for a user (`Delegator`) to delegate their funds to another account (`Agent`). Delegate implies the funds are locked in delegator account itself. Agent can act on behalf of delegator to stake directly on Staking pallet. The delegation feature is added to Staking via another pallet `delegated-staking` worked on [here](https://github.com/paritytech/polkadot-sdk/pull/3904). ## Introduces: ### StakingUnchecked Trait As the name implies, this trait allows unchecked (non-locked) mutation of staking ledger. These apis are only meant to be used by other pallets in the runtime and should not be exposed directly to user code path. Also related: https://github.com/paritytech/polkadot-sdk/issues/3888. ### Virtual Bond Allows other pallets to stake via staking pallet while managing the locks on these accounts themselves. Introduces another storage `VirtualStakers` that whitelist these accounts. We also restrict virtual stakers to set reward account as themselves. Since the account has no locks, we cannot support compounding of rewards. Conservatively, we require them to set a separate account different from the staker. Since these are code managed, it should be easy for another pallet to redistribute reward and rebond them. ### Slashes Since there is no actual lock maintained by staking-pallet for virtual stakers, this pallet does not apply any slashes. It is then important for pallets managing virtual stakers to listen to slashing events and apply necessary slashes.
NOTE: We have recently made significant changes to our repository structure. In order to streamline our development process and foster better contributions, we have merged three separate repositories Cumulus, Substrate and Polkadot into this repository. Read more about the changes here.
Polkadot SDK
The Polkadot SDK repository provides all the resources needed to start building on the Polkadot network, a multi-chain blockchain platform that enables different blockchains to interoperate and share information in a secure and scalable way. The Polkadot SDK comprises three main pieces of software:
Polkadot
Implementation of a node for the https://polkadot.network in Rust, using the Substrate framework. This directory
currently contains runtimes for the Westend and Rococo test networks. Polkadot, Kusama and their system chain runtimes
are located in the runtimes repository maintained by
the Polkadot Technical Fellowship.
Substrate
Substrate is the primary blockchain SDK used by developers to create the parachains that make up the Polkadot network. Additionally, it allows for the development of self-sovereign blockchains that operate completely independently of Polkadot.
Cumulus
Cumulus is a set of tools for writing Substrate-based Polkadot parachains.
Releases
Note
Our release process is still Work-In-Progress and may not yet reflect the aspired outline here.
The Polkadot-SDK has two release channels: stable and nightly. Production software is advised to only use stable.
nightly is meant for tinkerers to try out the latest features. The detailed release process is described in
RELEASE.md.
Stable
stable releases have a support duration of three months. In this period, the release will not have any breaking
changes. It will receive bug fixes, security fixes, performance fixes and new non-breaking features on a two week
cadence.
Nightly
nightly releases are released every night from the master branch, potentially with breaking changes. They have
pre-release version numbers in the format major.0.0-nightlyYYMMDD.
