Pactus 1.2.0 (Sydney) Released | Pactus.org

Overview

Pactus Blockchain Version 1.2.0 (Sydney) is now available for download. This release includes the following applications:

Pactus GUI: The graphical user interface (GUI) for the Pactus node that is suitable for both beginners and experienced users.
Pactus Daemon: The command-line interface (CLI) for the Pactus node that is suitable for experienced users.
Pactus Shell: The command-line tool that allows users to interact with a Pactus node.
Pactus Wallet: The wallet software that allows users to manage their wallet and send transactions without the need to sync the entire blockchain.

Highlights

This version includes some improvements and new features, such as:

Clock offset calculation: Adding clock offset check to alert the user if their machine’s time is not synced with the network. See PIP-18: Clock Offset Calculation.
Minimum fee: The minimum fee is configurable in this version, with the default set to 0.01. Each validator can decide the minimum fee of transactions they want to include in the block by changing the min_fee value inside the config file.
ip blocker: A new option allows nodes to block certain IPs and disconnect from them.
rate limit: Nodes can set rate limits for incoming messages, including transactions.
wallet manager: The wallet manager allows users to create and manage wallets using gRPC endpoints.
