Pactus 0.19.0 Released | Pactus.org

Overview

Pactus Blockchain Version 0.19.0 is now available for download. This release includes a graphical user interface (GUI) that is suitable for both beginners and experienced users. It also includes a command-line interface (CLI) for advanced users and wallet software that allows users to interact with the blockchain without the need to sync the entire blockchain.

Highlights

This version has improved the overall performance of the blockchain by implementing PIP-15. PIP-15 suggests to add caching algorithms to the database for the most frequently used items.

Additionally, this version has enhanced the connectivity of the nodes in the P2P network.

Availability Score

This version comes with the implementation of PIP-19. PIP-19 suggests assigning the “Availability Score” to each validator based on their activities in the committee. Validators with a score less than 0.8 won’t receive the block reward, as their proposals will be rejected by other validators. The main reason behind this PIP is to prevent users from downgrading their node specifications and running Pactus on machines with low resources.

Breaking change

The Docker container now contains both daemon and wallet binary files. Users who use Docker to run Pacts now need to add the entry point to run Pactus.

Download

This version has been implemented for Testnet-2 and is being prepared for the upcoming Mainnet launch. To start using Pactus Blockchain Testnet-2, download the latest version from the download page and join the Testnet.
