Oracles: The All-Seeing Eyes That Guide Crypto Networks

Oracles in DeFi 101: A Deep Dive by Tellor

## What Is DIA (DIA)?

DIA (Decentralised Information Asset) is an open-source oracle platform that enables market actors to source, supply and share trustable data. DIA aims to be an ecosystem for open financial data in a financial smart contract ecosystem, to bring together data analysts, data providers and data users. In general, DIA provides a reliable and verifiable bridge between off-chain data from various sources and on-chain smart contracts that can be used to build a variety of financial [DApps](https://coinmarketcap.com/alexandria/glossary/decentralized-applications-dapps).

DIA is the governance token of the platform. It is currently based on [ERC-20 ](https://coinmarketcap.com/alexandria/glossary/erc-20)Ethereum protocol.

The project was founded in 2018, while the token supply was made available to the public during the bonding curve sale from Aug. 3 through Aug. 17, 2020, where 10.2 million tokens were sold.


### Who Are the Founders of DIA?

The DIA association was co-founded by a group of a dozen people, though Paul Claudius, Michael Weber and Samuel Brack are the leaders.

Claudius is the face of the project and its lead advocate, sometimes also mentioned as a CBO. He has a masters degree in international management from ESCP Europe and a bachelors in business and economics from Passau University. Apart from working on DIA, he is also a co-founder and CEO of BlockState AG and c ventures. Before crypto, he had worked as director for a nutrition company called nu3.

Michael Weber is DIA's Founder and Association President. He holds degrees in management from ESCP Business School and an  economics and physics from University of Cologne, Germany.

He has worked in several banks and financial institutions before turning to crypto, where he founded such projects as Goodcoin, myLucy and BlockState. 

Samuel Brack serves DIA in the role of CTO. Like both Claudius and Weber, he shares the same position at BlockState. He has a masters degree in computer science from Humboldt University of Berlin, where as of January 2020, he is still studying for his PhD.


#### What Makes DIA Unique?

DIA aims to become the Wikipedia of financial data. It specifically addresses the problem of dated/unverified/hard to access data in the world of finance and crypto, especially [DeFi](https://coinmarketcap.com/alexandria/article/what-is-decentralized-finance), while proposing to solve it viaa system of financial incentives for users to keep the flow of open-source, validated data streams to the [oracles](https://coinmarketcap.com/alexandria/article/oracles-the-all-seeing-eye-that-guides-crypto-networks) up and running. The current design of oracles, DIA argues, is non-transparent, difficult to scale and vulnerable to attack.

The DIA governance token will be used to fund data collection, data validation, voting on governance decisions and to incentivize the development of the platform. Users can stake DIA tokens to incentivi`e new data to appear on the platform, but access to historical data though DIA is free.

#### How Many DIA (DIA) Tokens Are There in Circulation?

The total DIA token supply is limited with 200 million coins minted. 10 million tokens were initially sold at a private sale, 19.5 million are with early investors and advisors, Outlier Ventures being the largest. 30 million coins were offered for a bonding curve sale in August 2020, out of which 10.2 million were sold to the public, and the remaining 19.8 million burned. Another 24 million tokens are allocated to founders and team with a 29 month vesting period, and 25 million locked for the future use for the development of the DIA ecosystem. Finally,  91.5 million DIA tokens are in the company's reserve to be unlocked in equal parts over 10 years every December. Out of the first unlocked part, half of the tokens were burned in an instant, after the community vote makes the decision.

It is planned that smart contracts using DIA oracles will be receiving DIA Governance Tokens on a daily basis through what they call “proof-of-use” and “proof-of-truth” mechanisms.


### How Is the DIA Network Secured?

DIA is a standard [ERC-20 ](https://coinmarketcap.com/alexandria/glossary/erc-20)token, meaning it requires Ethereum to function, inheriting all its strengths and weaknesses. The Ethereum network is one of the largest and thus strongest because of its decentralization, as all transactions are protected by the Ethash [proof-of-work](https://coinmarketcap.com/alexandria/article/proof-of-work-vs-proof-of-stake) function. ERC-20 merely defines a set of rules for tokens to operate on. Downsides of Ethereum may be noticeable: for example, congestion can hike the price of [gas](https://coinmarketcap.com/alexandria/glossary/gas-price) needed to perform transactions, leading to delays and abnormally high transaction fees, which impact all participants.


### Where Can You Buy DIA (DIA)?

DIA is a freely-tradable token. Pairs available for trading include BTC, USDT and ETH The top exchanges for trading in DIA are currently [Binance](https://coinmarketcap.com/exchanges/binance/), [OKEx](https://coinmarketcap.com/exchanges/okex/), [HBTC](https://coinmarketcap.com/exchanges/hbtc/), [Bidesk](https://coinmarketcap.com/exchanges/bidesk/), and [BiKi](https://coinmarketcap.com/exchanges/biki/).

Ontology is a project designed to bring trust, privacy, and security to Web3 through decentralized identity and data solutions. It is building the infrastructure to provide trusted access to Web3, allowing individuals and enterprises to rest assured that through regulatory compliant digital identity solutions, users and their privacy come first.

The Ontology blockchain is a high speed, low cost public blockchain. It is designed to bring decentralized identity and data solutions to Web3, with the goal of increasing privacy, transparency, and trust. To achieve this, users and enterprises are provided with the flexibility to build blockchain-based solutions that suit their needs, while also ensuring regulatory compliance. Through Ontology’s Ethereum Virtual Machine (EVM), Ontology ensures frictionless compatibility with Ethereum, the first step in the creation of the Ontology Multi-Virtual Machine and further interoperability for the chain.

At its launch, Ontology chose to forego the popular initial coin offering (ICO) model in favor of a series of community distributions and airdrops of its ONT cryptocurrency.

This helped to quickly establish both organic price discovery and a passionate community and helped the project to avoid subsequent regulatory scrutiny.

For example, for a brief period any person who signed up for the Ontology newsletter received an airdrop of free 1,000 ONT, which reached a value of $10 per token soon after the token became listed on major exchanges like Binance.

Ontology launched its own MainNet on June 30, 2018 and has been up and running smoothly since.

Ontology

Bella Protocol is a platform that provides a suite of DeFi products designed to make crypto banking simpler and more accessible. The protocol aims to create a better user experience by eliminating the high fee and slow transaction issues that can affect some blockchain platforms — while simultaneously improving the user experience through its simplified DeFi smart portal.

Bella's smart pool feature allows users to access the best yields available in the DeFi market, while benefiting from nearly zero gas fees — since these are directly subsidized by the platform.

The project launched in September 2020 as the first project distributed via Binance’s Launchpool platform, and has secured investments from several prominent firms, including Arrington XRP Capital and Ledger Capital.

The protocol was built by the ARPA team, a blockchain-based layer 2 solution for privacy-preserving computation. The BEL token is an essential component of the Bella Protocol ecosystem and serves as both a reward token that allows holders to participate in the governance of the platform.

BEL can be used to farm fee rewards from the network, get exclusive discounts on Bella protocol products (such as its robo-advisor tool), and for earning staking rewards.

Bella Protocol

UMA was founded in 2018 by Allison Lu and Hart Lambur, two ex Goldman Sachs traders, with the goal of making global markets universally fair, accessible, secure and decentralized.

Ren (REN) is an open protocol built to provide interoperability and liquidity between different blockchain platforms.

To learn more about this project, check out our deep dive of Ren.

Formerly known as Republic Protocol, Ren launched RenVM, its virtual machine mainnet, in May 2020, having completed a $34 million initial coin offering (ICO) in 2018.

The protocol’s native token, REN, functions as a bond for those running nodes which power RenVM, known as Darknodes.

Ren aims to expand the interoperability, and hence accessibility, of decentralized finance (DeFi) by removing hurdles involved in liquidity between blockchains.

Linear is a decentralized delta-one asset protocol capable of instantly creating synthetic assets with unlimited liquidity. The project opens traditional assets like commodities, forex, market indices and other thematic sectors to cryptocurrency users by supporting the creation of “Liquids” — Linear’s synthetic asset tokens.

The protocol consists of various products like Linear.Buildr, a DApp used to manage Liquids using Linear (LINA) and other tokens as collateral. The exchange is specifically created to enable trading of a variety of Liquids with rapid confirmation times and robust security.

LINA is an ERC-20 token built on the Ethereum network whose main purpose is as collateral for Liquids (using Buildr) and for community governance of the protocol. All token holders have access to the Linear DAO, enabling them to vote on different initiatives and proposals, helping to shape the development of the Linear ecosystem.

The main goal of Linear is to provide a superior user experience with better scalability and greater speed thanks to the cross-chain capabilities of the protocol. Linear Finance intends to provide a simple solution for users that want exposure to traditional assets while still benefiting from the features enabled only by blockchain technology.
