The default trie cache size before was set to `64MiB`, which is quite
low to achieve real speed ups. `1GiB` should be a reasonable number as
the requirements for validators/collators/full nodes are much higher
when it comes to minimum memory requirements. Also the cache will not
use `1GiB` from the start and fills over time. The setting can be
changed by setting `--trie-cache-size BYTE_SIZE`.

The Polkadot SDK repository provides all the components 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.

⚡ Quickstart

If you want to get an example node running quickly you can execute the following getting started script:

curl --proto '=https' --tlsv1.2 -sSf https://raw.githubusercontent.com/paritytech/polkadot-sdk/master/scripts/getting-started.sh | bash

📚 Documentation

🚀 Releases

Current Stable Release  Next Stable Release

The Polkadot SDK is released every three months as a stableYYMMDD release. They are supported for one year with patches. See the next upcoming versions in the Release Registry.

You can use psvm to update all dependencies to a specific version without needing to manually select the correct version for each crate.

🛠️ Tooling

Polkadot SDK Version Manager: A simple tool to manage and update the Polkadot SDK dependencies in any Cargo.toml file. It will automatically update the Polkadot SDK dependencies to their correct crates.io version.

Polkadot Fellowship

Development in this repo usually goes hand in hand with the fellowship organization. In short, this repository provides all the SDK pieces needed to build both Polkadot and its parachains. But, the actual Polkadot runtime lives in the fellowship/runtimes repository. Read more about the fellowship, this separation, the RFC process here.

History

This repository is the amalgamation of 3 separate repositories that used to make up Polkadot SDK, namely Substrate, Polkadot and Cumulus. Read more about the merge and its history here.
