Pactus 1.15.0 (Bucharest) Released

Overview

Pactus Blockchain Version 1.15.0 (Bucharest) 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

The most significant change in the Bucharest release is support for the Secp256k1 cryptographic curve, introduced through Pactus Improvement Proposal 53 (PIP-53). This proposal adds support for the main elliptic curve used by Bitcoin and many other blockchain ecosystems, making it one of the most widely adopted cryptographic standards in the industry.

Secp256k1 support enables compatibility with a broad range of existing wallet solutions, including many popular hardware wallets. The feature has been implemented in this release and will be activated in the next protocol upgrade.

Another major addition is the new Config Editor, which allows node operators to manage and modify their node configuration through a user-friendly interface. This simplifies node administration and reduces the need for manual configuration file editing.

The GUI has also been migrated from GTK3 to GTK4, bringing the application onto a modern UI framework. This migration improves long-term maintainability, enables access to newer platform capabilities, and lays the foundation for future user interface enhancements.

In addition to these major features, the Bucharest release includes numerous performance improvements, stability enhancements, and bug fixes across the node, wallet, and supporting tools, resulting in a more reliable and streamlined user experience.
