Kraken is a popular cryptocurrency exchange that operates using a combination of centralized and decentralized technologies. The underlying technology behind Kraken is a hybrid model that leverages both centralized and decentralized components for optimal security and efficiency.
The primary blockchain used by Kraken is Bitcoin's blockchain, which is widely recognized as the most secure and established blockchain in the industry. By utilizing Bitcoin's blockchain, Kraken ensures the transparency and immutability of transactions taking place on its platform.
The functioning of Kraken involves a multi-step process. First, users sign up for an account on the platform, providing the necessary identification and verification documents. Once their accounts are verified, users can deposit funds into their Kraken wallets.
When it comes to trading, Kraken operates as a centralized exchange, matching buy and sell orders between users. It provides a user-friendly interface for placing orders and managing trades. Additionally, Kraken offers advanced trading features such as margin trading and futures contracts.
In terms of security, Kraken employs various measures, including cold storage for the majority of funds and encrypted communication protocols. This ensures that user funds are protected from potential hacking attempts.
Overall, Kraken's functioning is built on a hybrid model, combining the security of a blockchain with the convenience and user-friendliness of a centralized exchange. This allows users to trade cryptocurrencies in a secure and efficient manner.
DIA employs a comprehensive approach to fetching trade data from various sources, including both centralized and decentralized exchanges. The process differs depending on the type of exchange being referred to.
For centralized exchanges like Coinbase, Kraken, and Binance, DIA utilizes scraping to collect trade data directly from the exchange databases. This is achieved through the use of Rest APIs or WebSocket APIs. The frequency of data collection varies, typically ranging from 1 to 7 seconds, depending on the exchange. By retrieving data as close to the source as possible, DIA ensures high precision and accuracy.
In the case of decentralized exchanges, DIA retrieves trading data from various blockchains by subscribing to swap events in liquidity pools. This approach allows for the direct retrieval of data from the blockchain, ensuring enhanced accuracy and credibility. Some examples of decentralized exchange sources include Uniswap, curve.finance, and PancakeSwap.
When it comes to NFT marketplaces, DIA captures live trading data by monitoring and retrieving information directly from the integrated marketplace's smart contracts. The retrieval period typically ranges from 20 seconds to 1 minute, ensuring that all NFT transactions happening in real-time are accounted for. By leveraging this approach, DIA can provide accurate and customizable price feeds for the broader NFT market without relying on unreliable bid and offer data.
Overall, DIA's comprehensive data management strategy, utilizing scraping and direct blockchain retrieval, enables the provision of highly accurate and customizable price feeds for both cryptocurrency and NFT trading.
When it comes to building price oracles with Kraken trade data, DIA follows different processes depending on the type of exchange we are referring to.
For decentralized finance (DeFi) exchanges, DIA begins by cleaning and detecting outlier trade data. This step ensures that the price estimation process remains resilient against trades that deviate significantly from the current market price. Data points and sets lying outside an acceptable range determined by the interquartile range (IR) filter are excluded. This filtering helps remove irregularities caused by market manipulation, errors, or flash crashes. The remaining trades within the "middle" quartiles are then used for further processing.
DIA applies various price determination methodologies to calculate the final price for each asset. One example is the Volume Weighted Average Price (VWAP), which considers the different volumes of trades. Trades are weighted by their volume, and the accumulated volume-price-products are divided by the sum of all volumes combined.
On the other hand, for non-fungible token (NFT) collections, DIA follows a different process. The goal is to determine the floor price of an NFT collection. First, the on-chain trade data is processed through cleansing filters to exclude market outliers and manipulation techniques. Then, a pricing methodology is applied to determine the final price point.
One such methodology is the Floor Price, which provides the lowest sale price of an NFT collection recorded on the blockchain during a given time window. However, due to the potential for manipulation, DIA also offers advanced methodologies for pricing, such as the Moving Average of Floor Price. This methodology calculates the moving average of a collection's floor price, with customizable parameters like the length of the average and the size of the floor window. An interquartile range outlier detection filter is also applied to filter out malicious behavior like wash trading.
Overall, DIA employs different processes for computing trade data from Kraken, depending on whether it is for DeFi or NFT exchanges. These processes ensure the production of market-representative prices while mitigating the effects of outliers and manipulation techniques.
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.
