The Electric Coin Company, the overseer of the Zcash (ZEC) blockchain protocol, has released v2.0.7 where ZIP208 was implemented, and which will take effect when Blossom activates. Upon activation, the block times for Zcash will decrease from 150 seconds to 75 seconds, and the block reward will decrease accordingly.

The changes affect at what block height halving events will occur, but should not affect the overall rate at which Zcash is mined. The total founders’ reward stays the same, and the total supply of Zcash is decreased only slightly due to rounding.

This release also includes Blossom activation on testnet, bringing shorter block times. The testnet Blossom activation height is 584000.

Changes needed for the Insight explorer have also been incorporated into Zcash. The Zash team says that this is an experimental feature and therefore is subject to change.

More details can be found on GitHub.

Summary of changes included in v2.0.7 release:

  • Shorter block times.
  • Blossom activation on testnet.
  • Insight explorer changes.
