@Vanar Automated Transaction Fee Update Mechanism on Blockchain
The illustrated flowchart explains an automated mechanism for updating transaction fees on a blockchain network, designed to ensure fairness, efficiency, and price accuracy over time. This process becomes active after the first 101 blocks, allowing the network to stabilize before dynamic fee adjustments begin.
The workflow starts by checking whether the transaction fee needs to be updated. On every new block, the system compares the transaction fee (fee per transaction) of the latest block with the fee recorded 101 blocks earlier. This comparison helps identify any mismatch that may require a protocol-level update.
If the transaction fee remains unchanged, the system simply reuses the transaction fee available in the parent block, ensuring consistency and avoiding unnecessary recalculations. In this case, the process ends smoothly without additional computation.
However, if the transaction fee differs, the system initiates a price update process. It requests the latest token price using an external API. To maintain performance and prevent delays, the system waits for a response for up to one second. If a valid response is received within this time, the network calculates the new transaction fee based on the updated token price and applies it to future transactions.
If the API does not respond within the allowed time, the system falls back to using the last known block price. To ensure accuracy in subsequent blocks, the protocol retries fetching the updated price in the next block.
This approach balances decentralization, reliability, and efficiency. By limiting external dependencies with timeouts and fallback mechanisms, the blockchain avoids congestion while still adapting transaction fees to real-time market conditions. Overall, this automated fee update process enhances network stability, protects users from sudden price fluctuations, and ensures predictable transaction costs across the blockchain ecosystem.
