Introduction

We are delighted to announce a major milestone in Band v3's journey—introducing Router Protocol as the first Data Tunnel provider. This collaboration represents a significant step toward revolutionizing how price data flows across blockchain, further underscoring Band Protocol’s commitment to building an open data oracle for everyone.

What Is a Data Tunnel in Band v3?

Data Tunnel is one of the core features of Band v3, designed to relay aggregated price feeds from BandChain’s Concurrent Price Stream seamlessly to various blockchains and smart contract platforms.

Key features include:

• Aggregated Price: Prices recorded on BandChain are automatically relayed to destination platforms.
• Secure Relay Mechanism: Provides superior cryptographic guarantees through the Threshold Signature Scheme (TSS).
• Cost Efficiency: Minimizes the cost of proofs, making data relays more affordable.
• Open Access: Band Protocol collaborates with Router and other leading interchain messaging protocols to provide open access to price feeds.

Meet Band’s First Tunnel Provider: Router Protocol

Router Protocol is one of the leading blockchain interoperability platforms specializing in seamless, cross-chain communication. Its commitment to scalability, security, and efficiency makes Router the perfect fit for Band v3’s vision of open and decentralized data infrastructure.

Why Router is a Perfect Fit:

• Technical Expertise: Router’s technology aligns with BandChain’s architecture, ensuring smooth integration.
• Proven Track Record: Known for delivering secure and efficient data transfers across multiple blockchains.
• Ecosystem Alignment: Router shares Band Protocol’s mission to support developers with reliable, cost-effective tools.
• Technological Compatibility: Router Chain’s design is fully compatible with Cosmos, enabling seamless communication between Band Protocol and Router Protocol via IBC and CosmWasm.

With all these synergies, Router Protocol is the first data tunnel provider for Band allowing data stored on Band v3 to flow to different blockchains and ecosystems.

How Data Tunnel Works: A High-Level Overview

The Data Tunnel operates through the interaction between BandChain, Router Chain, and Destination Chains. Here’s a simplified overview:

1. Data Aggregation on BandChain: Aggregated prices from the Concurrent Price Stream are sent to the Data Tunnel module on BandChain. This module contains asset prices and specific commands detailing the routes to destination chains.
2. Encryption and Transmission: Once everything is aligned, price feeds are encrypted using the Threshold Signature Scheme (TSS).and sent via the Inter-Blockchain Communication (IBC) protocol to Router Chain’s CosmWasm module.
3. Processing on Router Chain: The Router Chain leverages its built-in CosmWasm module—enabled by the Cosmos SDK—to facilitate seamless communication and message exchange with BandChain.
4. Relay to Destination Chains: Router relays data from Band to Router-integrated chains, ensuring developers have effortless access to price feeds.

Impact of Band v3 with Router Protocol as Our First Data Tunnel Providers

Once Band v3 launches, Router Protocol as a Data Tunnel provider will enable all Router-supported chains to access Band Price Oracles with minimal integration effort.

This collaboration will:

• Expand Router Protocol’s service portfolio by including Band v3 Price Oracles in its interoperability offerings.
• Enhance the developer experience by delivering secure and decentralized price feeds across multiple chains without custom integration requirements.
• Accelerate the adoption of Band Oracles across Router’s growing ecosystem, fostering interoperability at scale.

Together, Band Protocol and Router Protocol are driving cross-chain innovation in DeFi and tokenized assets by enhancing blockchain interoperability and data infrastructure. As a result, end-users in Web3 will have continuous access to real-time, reliable price data.

Testimonials and Invitations to Developers

What’s Next?

With Router as our first Data Tunnel provider, Band v3 takes a significant step toward redefining how secure, cost-effective, and decentralized data flows across blockchain ecosystems. This is just the beginning. Band Protocol is actively collaborating with additional interoperability providers to decentralize and strengthen the Data Tunnel network further.

As Data Tunnels are still in an active development phase, there may be updates and clarifications on specific details as the feature evolves. Keep an eye on Band v3’s progress as we redefine the landscape of blockchain data oracles in Web3, delivering open and decentralized solutions to meet the growing demands of the ecosystem.

About Router Protocol

The Router Chain is a layer 1 blockchain that leverages tendermint’s Byzantine Fault Tolerant (BFT) consensus engine. As a Proof of Stake (PoS) blockchain, the Router Chain is primarily run by a network of validators with economic incentives to act honestly. The Router Chain is built using the Cosmos SDK and encapsulates all the features of Cosmos, including fast block times, robust security mechanisms, and, most importantly, CosmWasm - a security-first smart contract platform. By leveraging the CosmWasm toolkit, developers can start building secure blockchain applications on the Router Chain from scratch or port their existing applications to the Router Chain with minimal overhead.
