Avalanche Upgrades to 'Banff 5' to Introduce Direct Communication between Subnets

The Avalanche developers have upgraded AvalancheGo — the software implementation of the blockchain in the Go programming language — to "Banff 5."

The upgrade introduces a communication protocol for Avalanche-based blockchains (called subnets) known as Avalanche Warp Messaging. The feature will allow subnets to share data and crypto assets with each other to enable what's described as "seamless native communication" between subnets to transfer assets or data across different subnets.

AWM is available today in both the Golang and Rust VM SDKs for use by any VM builder. Soon, this capability will be rolled out to the subnet-evm, giving Subnet creators native, cross-chain communication capabilities out-of-the-box.
