A curated list of awesome blogs, events, docs, podcasts, videos, academic research, and, diagrams of Substrate, Polkadot, ParityTech and Web3 Foundation.
A curated list of awesome resources of Substrate, Polkadot, ParityTech and Web3 Foundation.
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
