Overview of Substrate

Translated version: 中文.

This is an up-to-date cheatsheet of news, events, and onboarding materials for Substrate.

Substrate is an open-source framework that lets you build entire, configurable blockchains in minimal time. Optionally, you can then deploy your blockchain to the Polkadot network, which has pooled security and other advantages. See a detailed summary here.

With Substrate, you get the following *customizable- functionalities out-of-the-box:

A default PoS blockchain
Upgradable runtimes
Pluggable consensus (PoS, PoW, PoA)
Block production, synchronization
Efficient storage
Efficient state machine
P2P networking layer
Built in crypto primitives
Light client support
Suite of libraries to modify runtime logic, i.e. manage storage, accounts, staking, a treasury, consensus and more
UI kits
