Camelot is a blockchain oracle that provides reliable data from external sources to smart contracts. It ensures the accuracy and integrity of off-chain information used in decentralized applications. Camelot was founded by a team of blockchain experts in 2020. The name is inspired by the legendary kingdom in Arthurian folklore, symbolizing trust and security. Key facts include its role as an information provider for smart contracts and its commitment to data verification.
Camelot is a blockchain oracle solution that brings several benefits compared to its direct competitors. One of the key advantages of using Camelot is its high level of security. The platform employs advanced security measures to ensure the integrity and accuracy of the data it provides to smart contracts. It uses cryptographic proofing mechanisms to validate and authenticate external data, making it extremely difficult for malicious actors to tamper with or manipulate the information.
Another notable benefit of Camelot is its flexibility and wide range of data sources. The platform supports multiple data providers, allowing users to choose from a diverse pool of trusted sources. This not only enhances the reliability of the data but also enables users to select the most relevant and up-to-date information for their specific needs.
Furthermore, Camelot offers seamless integration with various blockchain networks. It is compatible with popular blockchain platforms, ensuring smooth interoperability and easy integration into existing decentralized applications (dApps). This versatility sets Camelot apart from its competitors by providing developers with the freedom and flexibility to deploy blockchain oracles on different networks without facing significant compatibility issues.
Additionally, Camelot offers efficient and reliable data delivery. Its robust infrastructure and optimized protocols ensure fast and accurate data transmission, minimizing latency and improving overall performance. This is particularly crucial for time-sensitive applications that require real-time data updates.
In summary, Camelot distinguishes itself with its strong emphasis on security, wide range of data sources, compatibility with different blockchain networks, and efficient data delivery. These benefits position Camelot as a reliable and versatile choice for developers and users seeking a high-quality blockchain oracle solution.
Camelot is a blockchain-based platform that utilizes cutting-edge technology to provide a decentralized solution for various applications. The platform is built on the Ethereum blockchain, which is a popular choice due to its smart contract functionality and security features.
At its core, Camelot uses blockchain oracles to connect external data sources to the smart contracts running on the Ethereum network. A blockchain oracle acts as an intermediary between the off-chain world and the blockchain, ensuring that accurate and reliable data is fed into the smart contracts.
Camelot's functioning revolves around the concept of trustless data feeds. By leveraging oracles, Camelot enables smart contracts to securely access and verify real-world data, such as financial market prices, weather conditions, or any other information that needs to be processed on-chain.
The process begins with an external data provider, selected by Camelot, supplying information to the oracle. This data undergoes verification and authentication before being fed into the smart contracts. Once the data is validated, it becomes accessible to the applications and decentralized applications (dApps) built on Camelot.
This decentralized approach eliminates the need for a trusted third party, making the platform more transparent and less vulnerable to manipulation or tampering. It also enhances the efficiency and reliability of applications relying on real-time data.
By leveraging Ethereum as the underlying blockchain and implementing blockchain oracles, Camelot ensures the secure and trustworthy functioning of its platform, opening up a wide range of possibilities for decentralized applications and their users.
DIA employs a comprehensive approach to data management when it comes to fetching trade data from DeFi and NFT exchanges. The process varies depending on the type of exchange being referred to.
For centralized exchanges such as Coinbase, Kraken, and Binance, DIA utilizes scraping techniques to directly collect trades from the exchange databases. This is achieved by leveraging Rest APIs or WebSocket APIs to access the trade data. The frequency of data collection ranges from 1 to 7 seconds, depending on the exchange.
On the other hand, for decentralized exchanges like Uniswap, curve.finance, and PancakeSwap, DIA retrieves trading data directly from the blockchain. This is done by subscribing to swap events in liquidity pools on various blockchains. By retrieving the data directly from the blockchain, DIA ensures enhanced accuracy and reliability.
When it comes to NFT marketplaces, DIA captures live trading data by integrating with the smart contracts of these marketplaces. The retrieval period for NFT marketplaces ranges from 20 seconds to 1 minute, covering all NFT transactions happening in real-time. By focusing on the actual NFT transactions rather than unreliable bids and offers, DIA ensures precise and reliable data from the broader NFT market.
Overall, DIA's strategy involves leveraging a network of WebSockets and decentralized node providers to collect granular trade data from over 80 exchanges. This allows for a vast data availability of approximately 15 billion trades per day. By fetching data directly from exchange databases and blockchains, DIA can provide highly accurate and customizable price feeds for its users.
DIA builds price oracles by computing trade data from Camelot for both DeFi exchanges and NFT collections, but the process varies depending on the type of exchange.
For DeFi exchanges, DIA follows a two-step process. First, there is data cleaning and outlier detection to ensure the quality of the trade data. This involves removing trades with prices that deviate significantly from the market price to avoid irregularities caused by market manipulation, errors, or flash crashes. DIA applies an Interquartile Range (IR) filter to identify and exclude outliers. The remaining trades move forward for further processing.
Next, DIA applies price determination methodologies to calculate the final price. One example is the Volume Weighted Average Price (VWAP), which considers the different volumes of trades. Trades are weighted by their volume, and the volume-price-products are accumulated and divided by the sum of all volumes. Another methodology is the Moving Average with Interquartile Range Filter (MAIR), where trades are ordered by timestamp and weighted against the volume for each data point.
For NFT collections, the process for building price oracles is different. The trade data retrieved from the blockchain is first processed through cleansing filters to exclude market outliers and manipulation techniques. Then, a pricing methodology is applied to determine the final price point.
The simplest methodology is the Floor Price, which provides the lowest sale price of an NFT collection recorded on the blockchain within a given time window. However, this methodology can be manipulated by malicious actors using techniques like wash trading and sweeping the floor. To address this, DIA offers advanced methodologies such as the Moving Average of Floor Price, which calculates the moving average of a collection's floor price and applies an interquartile range outlier detection filter.
DIA is also open to discussing custom filters and methodologies for specific use cases beyond the implemented techniques.
Please note that this information is based on the general process followed by DIA to build price oracles and does not include specific details about DIA's technology or services.
Instead of distributing pre-calculated data feeds, DIA covers the whole data journey from individual trade collection, and computation to the last mile of the feed delivery.
