Today, we are excited to announce that Chorus One will join the Band Protocol ecosystem as a block validator and data provider.

Band Protocol is a data layer for Web 3.0 applications providing decentralized off-chain data to smart contracts through community-curated oracles. Band Protocol is backed by a strong network of stakeholders including Sequoia Capital, one of the top venture capital firms in the world, and the leading cryptocurrency exchange, Binance.

Band Protocol 2.0 introduces BandChain, a blockchain built on the Cosmos SDK to accommodate user-defined data requests and support data oracles across multiple blockchains. Dapps can use BandChain to query data from traditional APIs and send it to the smart contracts in a verifiable and secure manner.

Oracle Risks

We have seen how price oracles have the potential to cause chaos in crypto. Synthetix had a close call when their price oracle failed last year. Recent flash loan arbitrage trades have shown that automated market makers like Uniswap can be fragile when low liquidity is paired with leverage. Similarly Terra, where Chorus One also runs a validator, saw their stablecoin swap mechanism subjected to arbitrage attacks leading to an effort to continuously improve the robustness of their oracle implementation.

Why We Are Supporting Band Protocol

We believe Band Protocol has the capacity to help mitigate oracle risks through their novel incentivized model on BandChain that incorporates flexibility, customizability, and speed while also ensuring the security and integrity of the data.

As a validator and data provider on Band Protocol we hope to bring additional decentralization and security to all blockchain applications that seek to safeguard against critical failures arising from dependency on any sole oracle solution”

- Brian Fabian Crain, CEO & Co-Founder of Chorus One

Here are some of the reasons why we chose to support Band Protocol:

  • Customizable Data Querying
    Decentralized applications will have full flexibility to define how the data they need is sourced and aggregated. Hence, data feeds can be consumed safely whether through any developer defined method such as median, time-weighted, volume-weighted moving average.
  • Secure Connections to High Quality Data
    BandChain enables on-demand data query from any traditional open API and will be able to facilitate cross-chain payment for permissioned oracle data from private or credentialed APIs which deliver premium data.
  • Cross-Chain Compatible Solution
    With a key focus on being blockchain-agnostic and established partners such as Fantom, Kava, Tomochain and more - Band Protocol seamlessly connects to any other blockchain through bridge contracts or Cosmos-based blockchain through IBC.
  • Streamlined Data Request Mechanism
    By moving onto an independent blockchain, Band Protocol is able to produce real-time spot data by offloading all expensive computational oracle requirements including sourcing and aggregating onto BandChain so only the final value needs to be submitted to target blockchains.

Driving The IoB Vision With Band Protocol

As Chorus One, we strongly believe in the Internet of Blockchains vision, as espoused by Cosmos and others. We believe that there will be many blockchain networks that all interact with each other and that, over time, these chains will become increasingly specialized. These chains will use inter-blockchain communication, via protocols like the Inter-blockchain Protocol (IBC), to securely transact with each other.

One key problem for the Internet of Blockchains is that blockchains are unable to verify data that is created outside of their network. This is known as the “oracle” problem and technologies designed to solve this problem are called oracles. Financial contracts need market data, insurance contracts need IoT data, and gaming applications need provable randomness. The oracle problem is such a fundamental one, we believe there will be many competing solutions, all providing unique benefits and making various data feeds available.

So while we recently partnered with Chainlink, the current market leaders in this space, we also see Band Protocol playing a key role in the evolution of oracles in the Internet of Blockchains. In an IBC context, oracles can bridge the Internet of Blockchains to real world data. As the Band Protocol network is built using the Cosmos SDK, it can operate as a Cosmos “zone”. This means it will naturally fit into the world of chains communicating over the IBC protocol, bringing high-quality data feeds to other application-specific chains built using the Cosmos SDK.

We expect to see many applications choosing to partner with multiple oracle solutions to improve resilience, as per the recent bZx announcement, where bZx have decided to partner with both Chainlink and Band Protocol to improve their price feed oracles.

About Band Protocol
Band Protocol is a decentralized oracle framework for Web3.0 applications. Band Protocol connects smart contracts with trusted off-chain information, provided through community-curated oracle data providers. Blockchains are enabled to connect to any web API with assured data integrity through dPoS economic incentives through one simple function call. Developers using Band Protocol will be able to easily build and manage off-chain oracles, reputation scores, identity management systems and much more.
