The Starknet v0.12.1 upgrade introduces a substantial change in the operation of the sequencer. The prime objective of these changes revolves around improved transaction efficiency by handling failed transactions differently. Here’s a closer look at what the changes proposed in Starknet v0.12.1 mean for the users.
Resolving the Issue of Failed Transactions
In an ideal scenario, all transactions submitted are valid, but that’s not always the case. Invalid transactions end up consuming valuable sequencer resources without contributing any fees. In the current system, this creates wastage and reduces the potential for processing valid transactions.
The Starknet v0.12.1 upgrade, however, addresses this problem head-on. By putting failed transaction into a block, the system charges them a fee – turning an issue into a potential revenue stream. This also enhances the sequencer’s capability for processing valid transactions, thereby creating a win-win situation.
Implementing a Validation Stage
- The new update advocates the addition of a validation stage to the mempool. With this new phase, invalid transactions will be prevented from consuming the sequencer’s precious resources.
- Only those transactions that successfully pass through the validation stage will continue to progress further in the transaction processing.
- Transactions that fail validation are marked with a REVERTED status and included in the block, where they attract a fee. The screenshot below illustrates the changes:
Key Changes To The API
- An added transaction status – REVERTED.
- New fields in the transaction receipt to provide information on execution status and results.
The addition of these new fields and parameters provides more granular information and allows users to understand the progress of their transactions better.
Enhancing The Centralized Sequencer
One of the most significant changes included in the upgrade is to the centralized sequencer. The upgrade adds a separate validation phase. Here, the sequencer gets the authority to reject any invalid transactions even before their execution stage.
The underlying goal of this change is to enable optimization of the sequencer’s capacity by filtering earlier in the transaction pipeline. It includes failed transactions but also levies a charge on them.
The Upcoming Upgrade
As announced by Starknet, the 0.12.1 upgrade becomes operational on Mainnet in the coming week. This is a significant part of Starknet Quantum Leap, aiming to optimize sequencer use. The better filtering of transactions, imposition of fees, and better overall utilization promise faster and smoother transactions for all users.
Prepare to experience a drastic change in the way your transactions progress with the Starknet v0.12.1 upgrade.
