Token Bucket Implementation

Algorithm

A Token Bucket Implementation functions as a rate-limiting algorithm, crucial for managing network bandwidth or API request frequencies within cryptocurrency exchanges and financial derivative platforms. Its core principle involves refilling a ‘bucket’ with ‘tokens’ at a defined rate, representing permissible actions, and decrementing the bucket with each action taken, ensuring controlled throughput. This mechanism prevents system overload and mitigates denial-of-service attacks, particularly relevant in high-frequency trading environments where rapid order placement is common.
