• Band Protocol offers a decentralized data oracle that connects smart contracts such as Defi to external data and APIs. The project has raised ~$10.5 MM via private token sales and the Binance Launchpad Sale.

• The project uses Delegated Proof-of-Stake (DPoS) on its Cosmos-based blockchain. BandChain provides a decentralized, scalable, and cross-chain oracle solution for any decentralized finance application or smart contract developer.

• BandChain allows developers to customize and create a 'data oracle script' that allows smart contracts to connect to external data sources and APIs, and specify aggregation methods and security parameters.

• BAND is the native token of BandChain and is used as a medium of exchange for transfer/data request fees as well as staking to ensure accountability and secure data curation from a trusted global pool of validators.

1. What is Band Protocol (BAND)?

Band Protocol is a decentralized cross-chain data oracle platform that aggregates and connects real-world data and APIs to smart contracts. The protocol leverages BandChain, an independent blockchain built specifically for oracle computations including settlement, data sourcing, and aggregation, that is secured by delegated proof-of-stake to enable the following features:

• Decentralized economic incentive: BandChain nodes operate independently are required to stake BAND and reputation to uphold data integrity.

• Scalability: All oracle computations occur on BandChain with 2 seconds block time. Band oracles are not bottlenecked by speed and congestion of any native blockchain hosting the dApps such as the Ethereum network. This allows Band oracles to be able to respond swiftly to all the data requests from multiple blockchains independently of each other.

• Real-Time Data Query: Smart contracts can use Band Protocol to query data on-demand and receive a real-time ready to be confirmed on destination blockchains within 4-6 seconds.

• Flexibility: Create fully customizable oracle scripts on BandChain that specify any data sources or APIs to connect to, with customizable aggregation methods and security parameters.

• Real-time Payments: Data requests can be paid in real-time on Band Protocol as opposed to a large fixed cost to update reference data.

Band Protocol aims to drive a highly secure decentralized ecosystem by reliably connecting smart contracts with external data, bringing blockchain applications toward mass adoption though oracles managed by its DPoS consensus mechanism". BandChain will be built in 3 phases, to fully realize a multi-faceted oracle solution capable of dealing with all types of data sources.

• Phase 0 is the foundational version of BandChain that will enable BAND token transfer and staking for validators.

• Phase 1 supports querying from public and permissionless data sources as well as gas metering on WebAssembly scripts on-chain. This will enable the creation of fully customizable oracle scripts, multi-blockchain support, and a catalog of built-in oracle scripts that are readily available to be integrated into DApps.

• Phase 2 release improves on composability between multiple data request scripts and support for data sources under a paywall or permissioned API, allowing data source owners to collect revenue from usage. During Phase 2, developers will be able to utilize most of the data on the internet.

• Phase 3 supports private/identity oracle scripts and more payment options in the ecosystem, allowing developers to pay in a token of their choice or subscription model. The focus upon this release will complete the BandChain decentralize oracle network, ready to drive interoperability between smart contracts and traditional enterprise services.

Its value proposition is centered around the following areas:

• Band Protocol offers a fast, low-cost, and synchronous query model for decentralized applications.

• Through the DPoS consensus mechanism, Band Protocol offers a decentralized network where data providers have both money and reputation at stake.

• The BAND token aims to capture the network value of Band Protocol, rather than just being a simple payment token.

BAND Token Utility

The BAND Mainnet token for BandChain is necessary to secure and power the decentralized oracle network. The use-cases and utility of BAND include:

• Collateral/Stake for Validators: All validators are required to stake BAND with a higher stake equating in a high probability of being selected to fulfill data requests. Underperforming or malicious actors will result in having their tokens and thus value slashed.

• Medium of Exchange: BAND tokens are used to pay as a transaction, query fee, and also for data access behind paywall (private APIs).

• Participation in BandChain Governance: Token holders are able to vote for the protocol upgrades and parameter changes on BandChain. The governance process allows the token holders to have decision making power in shaping a truly decentralized oracle network on BandChain.

2.2 Key features (Updated as of August 12th 2020)

Architecture overview

Band Protocol aims to drive a secure decentralized ecosystem by reliably connecting smart contracts with external data. The protocol incentivizes multiple independent parties to work cooperatively to provide trusted data using a delegated proof-of-stake consensus. The Band ecosystem primarily consists of these participants:

• Validators are specialized entities responsible for the curation of data in return for a data request fee.

• Token Holders collectively share a governance stake in Band Protocol and are responsible for ensuring the high quality of data, by delegating BAND tokens to trusted validators in exchange for a portion of the query fee and block rewards.

• DApp Developers integrate Band Protocol to consume real-time trusted data on their smart contracts through their own customized oracle script, in exchange for a small (transaction) fee for the data request.

• Trusted data sources can choose to provide open APIs or monetize their APIs under a paywall for decentralized applications to consume as a stream of revenue.

Customizable Oracle Scripts

Developers can create their own custom oracle script on BandChain, which uses delegated-proof-of-stake to secure source data, the aggregation methodology, and security parameters such as validator confirmations.

The creation and editing of the oracle script are permissionless, allowing for quick iterations and the consumption of scalable real-time data. An illustrative example of how BandChain oracle works:

6. Band Protocol's activity and community overview

6.1 Social and community data

Strategy overview

The initial community development plan will be focused on both dApp developers and general crypto users. The team has created a strong network of developers, starting with the South-East Asian community where developers began building on Band Protocol.

Band Protocol will continue to expand global and local presence with regards to its developer communities.

Band Protocol focuses on three key groups for future community growth:

1. General community users: Band Protocol will focus on educating users on token staking and getting the most value out of holding BAND, along with promoting user-generated content. Band will reward users who contribute positively in community building, content creation and evangelizing Band Protocol through an Ambassador Program. The community management team will be available 24/7 to answer questions and facilitate discussions in community channels as well as engaging local events to educate and foster adoption of Band Protocol.

2. Developer community: Band Protocol focuses on giving developer support through both offline and online channels. By design, developers can integrate Band data with only a few lines of Solidity code. The simplicity of integrating Band Protocol makes it easy for any developer to experiment. With this advantage, Band will organize both online and local hackathons on a regular basis. Promising projects will be eligible for receiving funding and additional support through a Developer Grant Program.

3. Public validators: Band Protocol is targeting a global pool of 100+ nodes upon the completed rollout of BandChain to achieve the highest degree of decentralization as possible. Gradually, reputable and trusted public validators will be onboarded onto BandChain to ensure the stability of the network.
