Band Protocol has officially launched its much-anticipated Band v3 on the mainnet, marking a major advancement in decentralized data feed infrastructure. This upgrade is positioned as a transformative milestone that significantly enhances the network’s ability to support smart contracts and AI agents with secure, real-time data. By facilitating seamless connectivity between Web2 APIs and Web3 applications, Band v3 is expected to accelerate the expansion of decentralized ecosystems at an unprecedented pace.
The organization, which operates as a cross-chain oracle platform, emphasized the significance of this development through its official communication channels. The newly released version introduces a comprehensive overhaul of Band’s technical architecture and lays the foundation for greater scale, speed, and interoperability across blockchain networks.
Multichain Operability and Performance Boosts
Central to the release of Band v3 is its multichain operability, which includes a dramatic enhancement in performance metrics. The average block time has been reduced from roughly six seconds to just one second, a change that enables a threefold increase in throughput and a tenfold improvement in system efficiency. These optimizations are driven by three new architectural components that have been embedded into the protocol.
The upgrade introduces the Signaling Hub, a decentralized mechanism for symbol governance; the Concurrent Price Stream, which provides high-frequency asset pricing data; and the Data Tunnel, a system designed for secure cross-chain data relay. These components collectively support a more resilient and responsive data feed infrastructure, with mission-critical information such as validator reports and price updates safeguarded through a custom mempool.
Backed by Leading Validators
The enhanced mainnet has gained the support of prominent validators, including Binance Validator, Cosmo Station, HashKey Cloud, and Nansen. In addition to these leading participants, over 40 more validators are reportedly preparing to integrate with the Band v3 ecosystem. The data relays are further fortified through the Router Protocol, which ensures the integrity and accuracy of cross-chain communications.
The v3 infrastructure is also being integrated into chains that support Inter-Blockchain Communication (IBC) and IBC Hooks, expanding the reach of Band Protocol into broader cross-chain environments. This integration ensures that Band v3 can offer reliable oracle services to an even wider range of decentralized applications and networks.

Laying the Groundwork for Open Data Innovation
Band Protocol’s team considers this mainnet launch as the initial phase in a broader vision aimed at attracting more developers, protocols, and validators to its platform. The long-term objective is to foster a robust and scalable environment for decentralized applications that demand fast and reliable data services.
By delivering lower latency, improved scalability, and multichain compatibility, Band v3 is expected to shape the next generation of Web3 tools and platforms. The initiative is positioned to strengthen Band Protocol’s standing as a key player in decentralized data infrastructure and set new benchmarks for the performance of oracle networks.
In summary, the launch of Band v3 reflects a clear commitment to innovation, security, and efficiency in the Web3 space. With its revamped architecture and growing validator support, Band Protocol is preparing to lead the evolution of open and decentralized data ecosystems.
