Band Protocol is a decentralized data oracle platform built on the Cosmos network, designed to bridge real-world information with blockchain-based smart contracts. In today’s interconnected digital economy, smart contracts power decentralized applications (dapps) across finance, gaming, insurance, and more. However, these contracts are limited—they can only execute based on data available within the blockchain. To access critical off-chain data such as asset prices, weather conditions, or sports outcomes, blockchains rely on data oracles.
Band Protocol serves as one of these essential utilities, enabling secure and reliable transmission of external data onto various blockchains. While Chainlink remains the most widely recognized oracle solution—particularly in the Ethereum ecosystem—Band Protocol has carved out its own niche by focusing on cross-chain interoperability and high-performance data delivery through the Cosmos ecosystem.
By 2022, Band Protocol had expanded its reach to over 20 major blockchains, including Ethereum and BNB Chain, making it a versatile player in the decentralized infrastructure space. Its core blockchain, BandChain, operates as a Delegated Proof of Stake (DPoS) network where validators secure the system and deliver accurate data from trusted sources like CoinMarketCap, centralized exchanges, and financial APIs.

The Origins of Band Protocol
Founded in 2017 by a team of three Thai technologists—Soravis Srinawakoon (CEO), Sorawit Suriyakarn (CTO), and Paul Nattapatsiri (CPO)—Band Protocol emerged during the early wave of blockchain innovation. Srinawakoon, recognized in Forbes’ 30 Under 30 list, brought strong leadership vision, while Suriyakarn contributed deep technical expertise from prior roles at Quora and Dropbox.
Initial development was accelerated in 2019 following a $3 million funding round led by Sequoia India. At that stage, the team was still evaluating which blockchain framework would best support their vision—options included Ethereum layer-2 solutions, standalone chains, or Cosmos-based architectures. Ultimately, they chose Cosmos for its scalability, modularity, and interoperability features via the Inter-Blockchain Communication (IBC) protocol.
Band Protocol launched its mainnet—BandChain—in 2020 as a custom-built blockchain using the Cosmos SDK. This marked a pivotal moment: not only did it enable efficient cross-chain data transfers, but Band also became the first blockchain project to join OpenAPI, an industry consortium that includes tech giants like Google and IBM. This collaboration underscores Band’s commitment to standardizing data formats across digital platforms.
How Band Protocol Works: Oracle Infrastructure on Cosmos
At its core, Band Protocol functions as a decentralized oracle network that pulls off-chain data and delivers it securely to smart contracts across multiple blockchains. This process relies on two foundational components: BandChain and the Band Standard Dataset.
BandChain: A Purpose-Built Oracle Blockchain
BandChain is a high-throughput, low-latency blockchain optimized for data retrieval and validation. It uses the Cosmos SDK, allowing seamless integration with other Cosmos-based chains through IBC, while also supporting connections to non-Cosmos ecosystems like Ethereum and BSC.
When a dapp needs real-world data—say, the current price of Bitcoin—it submits a request via an oracle script. This script defines:
- Which data to fetch
- Which external sources to query
- How to aggregate results
Validators on BandChain execute this script by retrieving data from multiple predefined sources. They then submit individual data reports, which are aggregated into a single result using a median or weighted average algorithm. This final value is returned to the requesting smart contract.
Each query incurs a small fee paid in BAND tokens, incentivizing validators to provide timely and accurate responses.
Band Standard Dataset: Ready-to-Use Price Feeds
One of Band’s most widely adopted offerings is the Band Standard Dataset, a curated collection of price feeds for cryptocurrencies, fiat currencies (forex), and commodities like gold and silver. These feeds are optimized for use in DeFi protocols, where accurate pricing is crucial for lending, borrowing, trading, and synthetic asset creation.
Key advantages include:
- Multi-source aggregation for enhanced accuracy
- Low gas costs due to efficient data packaging
- Cross-chain availability, reducing dependency on single networks
- Customizable update intervals based on application needs
This dataset significantly lowers the barrier for developers integrating reliable price oracles into their dapps without building custom solutions.

The Role of the BAND Token
The BAND token is central to the protocol’s operation, serving multiple functions within the ecosystem.
Staking and Network Security
BandChain operates under a Delegated Proof of Stake (DPoS) consensus model. Validators must stake BAND tokens to participate in block production and data validation. The more BAND staked, the higher their chance of being selected to propose new blocks and earn rewards.
Non-validator users can also contribute by delegating their BAND tokens to trusted validators. In return, they receive a share of the staking rewards—typically distributed after deducting a commission fee set by the validator.
This delegation mechanism promotes decentralization by allowing smaller holders to participate in network security and earn passive income.
Payment for Oracle Services
Beyond staking, BAND tokens are used to pay for data queries executed through BandChain. Dapps pay fees in BAND when submitting oracle requests, creating a sustainable economic model that rewards validators and maintains service quality.
Tokenomics: Supply and Distribution
The BAND token has an inflationary monetary policy designed to maintain long-term network participation.
- Initial supply: 100 million BAND tokens at launch
- Inflation rate: Adjustable between 7% and 20% annually
- Target staking ratio: 66.6% (2/3 of total supply)
The inflation rate dynamically adjusts based on actual staking levels—if less than two-thirds of tokens are staked, inflation increases to incentivize more participation; if over-staked, it decreases to control supply growth.
Token allocation at genesis:
- Ecosystem Fund: 25.63%
- Foundation: 22%
- Team & Advisors: 5%
- Private Investors: 15%
- Public Sale: 12.37%
Remaining tokens were reserved for future incentives, partnerships, and community programs.
Frequently Asked Questions (FAQ)
Q: What makes Band Protocol different from Chainlink?
A: While both are oracle networks, Band Protocol leverages Cosmos’ high-speed architecture and IBC for faster cross-chain communication. It also offers standardized datasets out-of-the-box, whereas Chainlink often requires custom node setups.
Q: Can BAND tokens be staked?
A: Yes. Users can stake BAND directly or delegate to validators to earn rewards through transaction fees and block issuance.
Q: On which blockchains does Band Protocol operate?
A: Originally Cosmos-based, Band now supports over 20 chains including Ethereum, BNB Chain, Polygon, Avalanche, and Solana via cross-chain bridges.
Q: Is BandChain secure?
A: Security is maintained through decentralized validation, multi-source data verification, and economic incentives aligned via staking.
Q: How often is data updated on Band Standard Dataset?
A: Updates occur at regular intervals (e.g., every few minutes), configurable based on the specific feed and consumer requirements.
Q: Where can I buy BAND tokens?
A: BAND is listed on several major cryptocurrency exchanges and can be traded against BTC, ETH, USDT, and other pairs.
