Nano Node v11 has been released with Universal Blocks support
Canary release proposal under peer review. Initial release is currently planned with the next Nano Node release (v11)
Universal Blocks live on the Nano Beta Network
Started initial code review on February 28th, 2018
Currently, there are 4 types of blocks in the Nano protocol: send, receive, change and open. Universal Blocks consolidates these types into a single block type.
Once Universal Blocks are implemented, an account’s full state is in one bundle of data, which improves internal bookkeeping. Universal Blocks is a base feature which opens the door to many exciting opportunities.
