What is VERA (VRA)?

VERA (VRA) is a blockchain-based cryptocurrency that operates on the Verasity platform. Its purpose is to enable secure and transparent transactions within the platform's ecosystem, which supports online video content. VRA was founded in 2018 by David Orman, the CEO of Verasity. The name "VERA" is derived from the Latin word for "truth," reflecting the platform's goal of ensuring fair and reliable video monetization. It offers solutions for content creators, advertisers, and viewers, with features like rewarded video advertising and audience engagement tools.

How does VERA work?

VERA is a blockchain oracle platform that operates on the Ethereum blockchain. Blockchain oracles are crucial components that connect smart contracts with external data sources, facilitating the exchange of information between the on-chain and off-chain realms. VERA aims to provide reliable and verified data to smart contracts, ensuring the accuracy and integrity of data inputs.

At its core, VERA utilizes a decentralized network of nodes called validators, which retrieve, verify, and deliver external data to smart contracts. These validators are responsible for sourcing data from a wide range of trusted sources, such as APIs, web scraping, and off-chain databases. Once the data is collected, it undergoes a validation process to ensure its accuracy and reliability. This validation is carried out by multiple validators who independently verify the data before it is transmitted to the blockchain.

The VERA platform leverages the Ethereum blockchain for its transparency, security, and immutability. Ethereum acts as the underlying infrastructure where smart contracts are executed, and VERA's oracle service seamlessly integrates with this ecosystem. By using Ethereum, VERA ensures that the data retrieved from external sources is securely and transparently shared with smart contracts in a tamper-proof manner.

In summary, VERA functions by utilizing a network of validators to fetch and validate real-world data from various sources. The platform then securely delivers this verified data to smart contracts, enabling them to make informed decisions and perform actions based on real-time information from the external world.

What are the benefits of VERA?

VERA (Virtual Economic Research Assistant) offers several benefits compared to its direct competitors in the field of blockchain oracles.

Firstly, VERA provides a decentralized and trustless solution for accessing external data on the blockchain. Through the use of smart contracts and cryptographic verification mechanisms, VERA ensures the integrity and reliability of the data it provides. This makes it a more secure option compared to centralized oracles that may be vulnerable to manipulation or data tampering.

Secondly, VERA offers a wide range of data sources and data types. It is capable of retrieving and aggregating data from various off-chain sources, including APIs, websites, and other blockchain networks. This versatility enables VERA to support a broader range of use cases and applications, making it a more flexible choice compared to oracles that are limited to specific data sources or types.

Another advantage of VERA is its high degree of customization. It allows developers and users to configure the oracle to meet their specific needs and preferences. This customizability extends to parameters such as data aggregation methods, data frequency, and data filtering options. This level of control empowers users to tailor the oracle's functionality to their specific use cases, ensuring optimal performance and efficiency.

Lastly, VERA is designed to be cost-effective. It aims to minimize transaction costs associated with data retrieval and processing, making it a more affordable option for developers and users. This cost-efficiency, combined with its other benefits, positions VERA as a competitive choice compared to its direct competitors in the blockchain oracle space.

Overall, VERA's decentralized and trustless nature, wide range of data sources, customizability, and cost-effectiveness make it a compelling solution for accessing verified external data on the blockchain.

What is VERA used for?

VERA is a blockchain oracle that serves as an external information provider for smart contracts. It acts as a bridge between the blockchain and real-world data, allowing smart contracts to access and verify off-chain information in a decentralized and trustless manner.

One common use case for VERA is in decentralized finance (DeFi) applications. In DeFi, smart contracts often require real-time and accurate data such as price feeds, interest rates, or liquidity information. VERA can provide this data by sourcing it from various reliable and trusted sources, such as centralized exchanges or decentralized exchanges, and then feeding it into the smart contracts.

Additionally, VERA can be used for supply chain management. By leveraging VERA, companies can securely and transparently track and verify the movement of goods and raw materials along the supply chain. This can help alleviate issues such as counterfeit products or unethical sourcing practices by ensuring that the information stored on the blockchain is accurate and tamper-resistant.

Another specific use case for VERA is in the gaming industry. With the integration of blockchain technology in gaming, VERA can provide real-time and provably fair game results, ensuring transparency and trust for all participants. For example, VERA can verify the outcome of random number generation for in-game items or determine the winner of a multiplayer competition.

In summary, VERA is a blockchain oracle that enables smart contracts to access and verify real-world data. While it is commonly used in DeFi applications, it also has applications in supply chain management and gaming, among others.
