Lisk Core Documentation
Table of contents
Lisk Core is the program that implements the Lisk Protocol. Every machine must set it up in order to run a node that allows for participation in the network. Setting up Lisk Core enables a user to:
- Contribute to the decentralisation of the Lisk network
- Explore data recorded on the Lisk blockchain
- Post transactions to the Lisk blockchain
- Enable/Disable forging for a registered delegate
- Configure Lisk Core to specific needs, as required
An instance of Lisk Core is generally detailed in two different ways:
A Lisk Core instance connected to a network is referred to as a Lisk Node.
A Lisk Node connected to other Lisk Nodes is referred to as a Lisk Peer.
Both meanings refer to a machine which, after installing and executing Lisk Core, become a server. The server participates in the network and provides blockchain data to its clients.
Lisk Core can be connected to different networks. There are two key public networks, entirely independent of each other, that are always accessible: Mainnet and Testnet.
Mainnet is where the true Lisk economy exists. On this network, Lisk users are able to transfer LSK tokens from one account to another, register accounts as delegates, vote for another delegates or register dApps. It can be explored via the Lisk Explorer.
Testnet is an independent replica of the Lisk Mainnet intended as an area to rehearse upgrades before they take place on the Lisk Mainet. This is where new versions and fixes of Lisk Core are tested. It can be explored via Lisk Tesnet Explorer.
The Lisk Core consists of 3 main components:
PostgreSQL is a powerful, open source object-relational database system with over 30 years of active development which has earned it a strong reputation for reliability, feature robustness, and performance. All Information on the Lisk mainchain is stored inside of PostgreSQL databases.
Redis is an open source, in-memory data structure store. Lisk Core mainly uses it to cache database query results. This prevents performance drops in the applicationn, for example when the same DB queries are sent repeatedly.
