What is Blossom?
Blossom is the third network upgrade for Zcash.
This feature increases the frequency of blocks (subject to further security and performance analysis), allowing transactions to resolve faster. This will improve Zcash’s usability and increase how many transactions per hour the network can sustain while keeping transaction fees low.
How do I upgrade?
This feature has undergone a specification audit, and is currently being tested on testnet as part of the Blossom Network Upgrade Pipeline before version 2.1.0 of zcashd, supporting mainnet activation, is released in September.
