Solidus is live on the Nano network
Nano Node v19 marches onto the main net
We are pleased to announce the release of the latest version of the Nano node software, in what is one of the most extensive protocol updates to date. Through a collection of significant updates and smaller targeted optimizations, Solidus brings the resilience and immutability necessary to foster trust and confidence in Nano as a leading digital currency.
The V19.0 release would not have been possible without our army of community beta-testers and contributors who have committed to providing the most efficient and comprehensive beta testing to date. Their work has been instrumental in ensuring that Solidus is well prepared for launch and we would like to extend our appreciation to all of the people involved in contributing to this release.
Before we get into the great features, there are some important upgrade considerations to call out. All node operators, services and exchanges integrating with Nano should closely review these details before upgrading.Key upgrade considerations Version Limits
Upgrades from versions V17.1 and earlier to V19 will involve a sequential database upgrade and impact participation of the node on the network. RPC calls will be unavailable for a long period of time amongst other impacts. It is highly recommended that nodes are upgraded to V18.0 first or a V18.0 ledger is acquired and used when upgrading to V19.0.Confirmation tracking considerations
The addition of confirmation height to the database requires the node to validate that blocks are confirmed before the cementing can occur. This process can take up to 24 hours or longer to complete but won’t impact participation on the network. For integrations watching confirmations, the existing HTTP callback, block_confirm RPC and confirmation_history RPC methods will continue to function as before, however it is required that tracking of confirmed block hashes...
