What is Blossom?

Blossom is the third network upgrade for Zcash, and in accordance with the Zcash trademark agreement, it is endorsed by both Electric Coin Co. and the Zcash foundation.

Improvements

Shorter Blocktimes

This feature increases the frequency of blocks, 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.

To keep the emission rate and halvening schedule of Zcash unchanged, the halved block times also require that the per-block reward be halved. The emission rate per time, however, remains unchanged.
