Horizen Labs builds programmable, customizable blockchains with a focus on privacy and scalability. It offers an SDK that lets developers create custom blockchains and a product called zkAudit, a privacy-enabled audit system that verifies data without revealing it. These products run on a proof-of-stake infrastructure to be secure and energy-efficient. The company differentiates itself through its use of zero-knowledge cryptography (zk SNARKs) to enable confidential transactions and audits, combining developer tools with privacy-preserving solutions for businesses across finance, supply chain, healthcare, and more. The goal is to provide secure, scalable, and privacy-enhanced blockchain solutions that help organizations adopt blockchain technology while protecting sensitive information.

Horizen Labs launches Vela to enable private execution on public blockchains.

Horizen Labs launches Vela to enable private execution on public blockchains. EtherX March 19, 2026 Horizen Labs has officially introduced Vela, a new solution designed to bring private execution capabilities to public blockchains, marking a major step forward in blockchain privacy and scalability innovation. The launch aims to address one of the most pressing challenges in decentralized systems: how to maintain transparency while protecting sensitive data. The introduction by Horizen Labs of Vela into the market for carrying out private transactions within the public ledger is meant to improve on what has been referred to as the transparent but insecure nature of decentralized systems when viewed against some private information. Vela Brings Privacy Layer to Public Blockchain Infrastructure By introducing Vela, which is a private execution solution by Horizen Labs for applications in public blockchain, developers can now transact and execute smart contracts with added privacy. Public blockchains are recognized for their transparency, whereby transaction information can be seen by all users. Although this feature enhances trust, it also restricts the usability of data-sensitive applications like financial transactions, corporate activities, and identity management. Vela solves this problem by providing for confidential computation layers that take advantage of the security provided by public blockchain networks. "Our objective in developing Vela was to create opportunities for those programmers who require privacy features that are consistent with a decentralized system," said a spokesperson from Horizen Labs. Expanding Use Cases for Enterprise and DeFi Applications It is anticipated that the Horizen Labs Vela private execution technology supporting DeFi and enterprise blockchain use cases will create new opportunities across various sectors. Privacy-enhanced transactions in decentralized finance (DeFi) could enhance user security and reduce risks related to front-running, as well as information leakage for enterprises being able to process confidential data on-chain while maintaining its secrecy. This may spur the adoption of blockchain technology in finance, health care, and supply chain management sectors. According to industry analysts, solutions such as Vela play a crucial role in closing the gap between the transparency of public blockchains and the privacy needs in the real world. Strengthening Blockchain Scalability and Security The impact of Horizen Labs Vela on blockchain scalability and secure private computation extends beyond privacy alone. By enabling off-chain or protected execution environments, Vela can help reduce congestion on public networks while maintaining data integrity. This approach enables developers to create leaner applications that do not overwhelm the blockchain infrastructure. Nonetheless, security is paramount; hence, Vela is structured in such a way that it guarantees verifiable and reliable private computations. The Emergence of Privacy in Web3 and Its Prospects The introduction of Vela by Horizen Labs has seen to it that there can be private execution even for the Web3 applications, which is just but a part of the wider move towards the integration of privacy solutions within decentralized ecosystems. There is an increasing demand for privacy-enhancing measures as blockchain technology advances. Programmers and businesses now want to create safe, adaptable, and lawful programs through some specialized means. By rolling out Vela, Horizen Labs positions itself as a leader in redefining the interplay between privacy and transparency in the future blockchain technology era. Posted by: etherx.
