Obscura Brings Bulletproofs++ to the Beldex Mainnet for Sustainable Scaling

Since 2018, Beldex has evolved into a major privacy network with a growing ecosystem of decentralized, privacy-preserving dApps. From private messaging to anonymous browsing, Beldex ensures confidentiality across every user interaction. As the network expands, managing blockchain size becomes challenging, especially because private transactions carry more cryptographic data.

To address this challenge, Beldex introduced the Obscura hardfork, which went live on December 7, 2025, at block height 4939540. While the upgrade includes multiple refinements, its core improvement is the integration of Bulletproofs++, a more compact and efficient range-proof system designed to keep the chain lightweight and scalable.

What is the Obscura Hardfork?

Obscura is a major technical upgrade focused on improving proof efficiency and transaction scalability. Its primary objective is to ensure that Beldex can maintain transactional privacy without increasing block load or compromising node performance.

The introduction of Bulletproofs++ is the core objective of this hardfork, enabling Beldex to significantly reduce transaction sizes while enhancing verification speed and long-term sustainability.

How Bulletproofs Work

Bulletproofs are non-interactive zero-knowledge range proofs. They allow Beldex masternodes to verify that transaction amounts are valid positive and within a defined range, without revealing the actual amounts.

As the number of outputs increases, the proof size grows very slowly. This makes Bulletproofs ideal for privacy-focused blockchains where transaction amounts remain hidden and efficient scaling is essential.

How Bulletproofs++ Improve Efficiency

Bulletproofs++ are an evolution of standard Bulletproofs. They retain the same cryptographic guarantees but produce significantly smaller proofs.

• A typical Bulletproof output previously required 600–700 bytes.

• Bulletproofs++ reduce this by 30–40%, with an average reduction of around 38%.

  \ This improvement directly impacts network efficiency:

• More transactions fit within each block

• Proof generation and validation become faster

• Nodes require less storage and processing power

• The chain grows more slowly, supporting long-term sustainability

Why Bulletproofs++ Are Important for Beldex

Private transactions inherently carry more data due to the cryptographic components required to preserve anonymity. As usage increases, these components become one of the biggest contributors to chain weight and storage pressure.

Beldex uses a fixed block size ranging between 300 kB and 600 kB, depending on dynamic conditions. Inefficient proofs can quickly consume available block capacity, limiting throughput and increasing verification time.

Bulletproofs++ solve this structural limitation:

• Lighter proofs - Lighter blocks
• Lighter blocks - Lower hardware requirements for masternode operators
• Lower requirements - Higher participation and stronger decentralization
• Faster verification - Improved network responsiveness

What Obscura Unlocks for the Network

Obscura is more than an optimization, it’s a critical step toward sustainability and scalability for privacy-preserving blockchains. The integration of Bulletproofs++ strengthens Beldex in several key ways:

• Higher throughput due to smaller transaction footprints
• Reduced storage overhead for long-term node operation
• Improved verification speed for smoother network performance
• A lighter, more efficient chain capable of supporting future growth

The Obscura hardfork marks a pivotal moment in Beldex’s technical evolution. By integrating Bulletproofs++, Beldex significantly reduces proof sizes, improves verification efficiency, and strengthens its foundation for long-term scalability.

This upgrade ensures that the network remains fast, private, and sustainable, even as adoption increases. With Obscura, Beldex reinforces its commitment to delivering high-performance privacy while future-proofing its infrastructure for the next generation of decentralized applications.
