The state of Layer-1 and Layer-2 Blockchain Scaling
Blockchain scalability presents challenges with increased adoption, resulting in congestion, high fees, and limited throughput. This article aims to provide a comprehensive list of feasible scaling solutions and track the latest developments in this area.
Trading data from faulty WebSockets and slow-responding REST APIs: System Design and Implementation
Following problem analysis and proposing optimal solutions, we proceed with the system design and implementation of crucial system components for the Historical Trading Data Service
Constructing a resilient crypto trading database: Data from faulty WebSockets and slow-responding REST APIs
Building historical trading data faces problems from the unreliability of crypto API endpoints, especially WebSockets. This hinders the retrieval of accurate high-frequency data, like pricing information. Our mission is to calculate a precise rolling 5-minute VWAP by ticker, correcting historical data for trade errors and ensuring accuracy
