Canton Network: March 31 Fork and Fee Updates
Summary
Canton Network announces three key updates: batched and weighted featured app markers arriving on MainNet March 31 to reduce costs and speed traffic, free confirmation responses now live to lower node fees, and a mandatory fork on March 31 requiring upgrade to Splice 0.5.11 to avoid incompatibility. These changes improve transaction efficiency and network bandwidth.
Three important updates:
Batched and Weighted Featured App Markers ~~are live on MainNet as of last week (Splice 0.5.11)~~. Coming March 31st to MainNet. This will make it possible to replace App Markers with a single weighted marker setting a weight equivalent to the nominal traffic cost of the transaction. Multiple markers will be be processed as a batch. Implementing weighted and batched markers reduces your total transaction cost, speeds up transaction processing, and makes more bandwidth available across the network.
- This is an intermediate step on the path toward traffic-based app rewards (CIP-0104).
Free confirmation responses went live last week. This means that if your node hosts parties that are involved in transactions that they do not submit, your node does not need to pay a traffic fee to submit confirmation responses for those transactions.
Fork coming March 31st. Splice 0.5.11 introduces Daml models that will fork any node that does not upgrade to at least 0.5.11 before those Daml models go live. These models were previously scheduled to go live yesterday, but that has been delayed until March 31st to resolve a bug in a dependent process on the Sequencer
